How can I efficiently import css values into javascript file? - javascript

I have a colors.less file that maintains consistent color palette for a site.
I also have a chart.js file that requires hard coded colors to display chart elements in appropriate colors.
How can I make the chart colors dependent on the generated colors.css file?
So far I've been maintaining two color palettes, one in less and another in js. How can I merge the two?
Example:
/* colors.less */
#green: #46a546;
#red: #9d261d;
#yellow: #f1c40f;
and
/* chart.js */
var chartElements = {
"apples": {
label: "Apples",
color: "#46a546",
},
"oranges": {
label: "Oranges",
color: "#f1c40f",
},
"grapes": {
label: "Grapes",
color: "#9d261d",
}...
How can I stop maintaining both sets of colors?

Even tho Pointy's answer may fit better here (talking about LESS), I want to remind that you can access stylesheet data directly via ECMAscript. You might be able to identify a specific rule and just grab the value. Might look like
[].forEach.call(document.styleSheets, function( set ) {
if( set.href && set.href.indexOf( 'dialog.css' ) > -1 ) {
[].forEach.call( set.cssRules, function( rule ) {
if( rule.selectorText === 'div#dialog-container-left' ) {
// to whatever here, grab the value and store it for global application usage
console.log( rule.style.backgroundColor );
}
});
}
});

Having that exact problem, I "solved" it with the following hack.
The CSS includes a list of "swatch-nn" classes (swatch-1, swatch-2, and so on). Those get the pre-defined LESS constants as their background color. (For me, a simple numerically-ordered list works; other situations might call for other approaches.)
My SPA wrapper creates a (hidden) list of elements that have the swatch classes.
<div id=swatches>
<div class=swatch-1>
<div class=swatch-2>
<!-- etc -->
</div>
Some JavaScript code at application startup populates a globally-available list of colors from the swatches.
var swatches = {}, $swatchContainer = $("#swatches"), rname = /\bswatch-(.*)\b/;
$swatchContainer.children("div").each(function() {
var swatch = this;
this.className.replace(rname, function(_, label) {
swatches[label] = $(swatch).css("backgroundColor");
});
})
$.swatches = swatches;
My Chart.js code thus copies the color values out of that global array. It's crude but it works fine.

How to change styling of cells that has been edited in ag-Grid?

I want to mark cells who has been edited so the user can see which cells have been touched and altered. I know there is a cell flash option, but that just changes the background colors for a bit. What I want is a background color change when an edit has been done.
Cannot seem to find any specific documentation on accessing for example the html element or the styling of affected cell.
Anyone got any ideas?
You can use ColDef.onCellValueChanged to detect if something changes and update the cell style accordingly using GridApi.refreshCells()
const columnDefs = [{
headerName: "Athlete",
field: "athlete",
onCellValueChanged: this.markAsDirty
},...]
...
private markAsDirty(params: ICellRendererParams) {
params.colDef.cellClass = (p) =>
p.rowIndex.toString() === params.node.id ? "ag-cell-dirty" : "";
params.api.refreshCells({
columns: [params.column.getId()],
rowNodes: [params.node],
force: true // without this line, the cell style is not refreshed at the first time
});
}
In your css file
:host ::ng-deep .ag-cell-dirty {
background-color: rgba(255, 193, 7, 0.5) !important;
}
You may also want to use defaultColDef if you want this behavior applied to all columns
this.gridOptions = {
defaultColDef: {
editable: true,
onCellValueChanged: this.markAsDirty
},
};
Live Demo
I did this on a project I was working on.
There is a cellClass property that you can define in your column definitions (https://www.ag-grid.com/javascript-grid-cell-styles/) and it can take a callback function with params: CellClassParams.
So try doing:
cellClass: (params: CellClassParams) => {
// you need to have a handle on the original untouched data
// See if the original value does not equal the modified value in params
// For shortness, I will write pseudocode
if (originalValue !== modifiedValue) {
return 'ag-cell-was-modified';
}
}
If many columns are editable, you may want to use a re-usable function for cellClass for each column.
That should apply the class ag-cell-was-modified conditionally whether the cell was modified or not and in your style.scss or main stylesheet, you can add:
.ag-cell-was-modified {
background: red;
}
Of course, if you are using SASS, you can place this class definition in somewhere more appropriate.

UI5 application (in WebIDE): sap.m.ColumnListItem: Change entire row color depending on a value in one column: What is wrong?

I googled how to change the color of a row inside a table ( ColumnListItem ) based on a value inside a column. I found a lot of google results and from all of the results I chose the one, which avoids to use predefined ( or individually defined ) css's inside my project folder.
BTW, even inside the F12-browser-tools (modifying the css orsuch stuff at the frontend) seems not to work as expected.
I followed this approach ( quite old post ) and cannot get it working:
https://archive.sap.com/discussions/thread/3360580
The table line simply should become green, yellow, or red.
This is my code so far, inside onInit ( first part, creating the template )
var oTable = this.byId("companySecret");
var oView = this.getView();
var oTemplate = new sap.m.ColumnListItem({
cells: [
new sap.m.Text({
text: "{Col1}"
}),
new sap.m.Text({
text: "{Col2}"
}),
new sap.m.Text({
text: "{Col3}"
}),
//
// ALL OTHER COLUMNS
//
// The only difference is that I do this inside the "loop".
new sap.ui.commons.TextView({
text: "{Color}"
}).bindProperty("text", "Color",function(cellValue)
{
var backgroundColor = "red";
var cellId = this.getId();
var row_col = $("#"+cellId);
// As You see, I am quite desperate
$("#"+cellId).css("background-color","#FF0000");
$("#"+cellId).parent().css("background-color","#FF0000");
$("#"+cellId).parent().parent().css("background-color",'#FF0000');
$("#"+cellId).parent().parent().parent().css("background-color","#FF0000");
$("#"+cellId).parent().parent().parent().parent().css("background-color","#FF0000");
$("#"+cellId).parent().parent().parent().parent().parent().css("background-color","#FF0000");
return cellValue;
})
]
});
Immediately after these lines, the binding is initiated like this:
var sUrl = "/sap/opu/odata/sap/Z_COMPANY_SECRET/";
var oModel = new sap.ui.model.odata.v2.ODataModel(sUrl, false);
oTable.setModel(oModel);
oTable.bindAggregation("items", {path: "/Company_Secret", template: oTemplate });
So, what am I missing ? In the referred link the adopted answer is flagged as "helpful" so it MUST work. Any hints ? Thx in advance.
To manipulate a table line, I generally use a custom attribute on the row via XML:
<Table>
<columns>
<Column><Text text="value"/></Column>
</columns>
<items>
<ColumnListItem type="Active">
<customData>
<core:CustomData key="color" value="{= ${MyArgument} ? 'red' : 'green'}" writeToDom="true" />
</customData>
<cells>
<ObjectIdentifier text="{Value}"/>
</cells>
</ColumnListItem>
</items>
</Table>
This writes a data attribute called data-color to the tr element on the DOM with value either red or green. Expand this with your own logic, or use a formatter like you would on any other value if the check is to long or unwieldy.
You can then manipulate the attribute via your included CSS file:
tr[data-color="red"] {
background-color: red;
}
Works for me.
You might be able to do something like
document.querySelectorAll('tr[data-color="red"]').forEach(s => s.style.backgroundColor = 'red');
I know this is already an old question, but might be able to help others.
Jorg's answer is probably the cleaner approach. I use the same approach as well.
Generally, it's cleaner and a lot safer to avoid using and accessing auto-generated Control-IDs (especially with the jQuery selector) as these IDs are most likely to change whenever the model it's bound to is refreshed.
By using the CustomData-CSS approach, you get to take advantage of the binding and not worrying about changing IDs or finding the right ID for a list/row item that's bound to change anyway, when the model is refreshed.
You just have to maintain some CSS. Which is simpler and much cleaner. :)
If it helps, I converted your code to conform to Jorg's answer.
See below:
new sap.ui.commons.TextView({
text: "{Color}"
}).addCustomData(new sap.ui.core.CustomData({
key: "color",
value: "{= $(argument) ? 'red' : 'green'}",
writeToDom: true
}));
And in CSS, should be the same as Jorg's:
tr[data-color="red"] {
background-color: red;
}
I hope this helps!

Using Javascript loop to create multiple HTML elements

I would like to use a javascript loop to create multiple HTML wrapper elements and insert JSON response API data into some of the elements (image, title, url, etc...).
Is this something I need to go line-by-line with?
<a class="scoreboard-video-outer-link" href="">
<div class="scoreboard-video--wrapper">
<div class="scoreboard-video--thumbnail">
<img src="http://via.placeholder.com/350x150">
</div>
<div class="scoreboard-video--info">
<div class="scoreboard-video--title">Pelicans # Bulls Postgame: E'Twaun Moore 10-8-17</div>
</div>
</div>
</a>
What I am trying:
var link = document.createElement('a');
document.getElementsByTagName("a")[0].setAttribute("class", "scoreboard-video-outer-link");
document.getElementsByTagName("a")[0].setAttribute("url", "google.com");
mainWrapper.appendChild(link);
var videoWrapper= document.createElement('div');
document.getElementsByTagName("div")[0].setAttribute("class", "scoreboard-video-outer-link");
link.appendChild(videoWrapper);
var videoThumbnailWrapper = document.createElement('div');
document.getElementsByTagName("div")[0].setAttribute("class", "scoreboard-video--thumbnail");
videoWrapper.appendChild(videoThumbnailWrapper);
var videoImage = document.createElement('img');
document.getElementsByTagName("img")[0].setAttribute("src", "url-of-image-from-api");
videoThumbnailWrapper.appendChild(videoImage);
Then I basically repeat that process for all nested HTML elements.
Create A-tag
Create class and href attributes for A-tag
Append class name and url to attributes
Append A-tag to main wrapper
Create DIV
Create class attributes for DIV
Append DIV to newly appended A-tag
I'd greatly appreciate it if you could enlighten me on the best way to do what I'm trying to explain here? Seems like it would get very messy.
Here's my answer. It's notated. In order to see the effects in the snippet you'll have to go into your developers console to either inspect the wrapper element or look at your developers console log.
We basically create some helper methods to easily create elements and append them to the DOM - it's really not as hard as it seems. This should also leave you in an easy place to append JSON retrieved Objects as properties to your elements!
Here's a Basic Version to give you the gist of what's happening and how to use it
//create element function
function create(tagName, props) {
return Object.assign(document.createElement(tagName), (props || {}));
}
//append child function
function ac(p, c) {
if (c) p.appendChild(c);
return p;
}
//example:
//get wrapper div
let mainWrapper = document.getElementById("mainWrapper");
//create link and div
let link = create("a", { href:"google.com" });
let div = create("div", { id: "myDiv" });
//add link as a child to div, add the result to mainWrapper
ac(mainWrapper, ac(div, link));
//create element function
function create(tagName, props) {
return Object.assign(document.createElement(tagName), (props || {}));
}
//append child function
function ac(p, c) {
if (c) p.appendChild(c);
return p;
}
//example:
//get wrapper div
let mainWrapper = document.getElementById("mainWrapper");
//create link and div
let link = create("a", { href:"google.com", textContent: "this text is a Link in the div" });
let div = create("div", { id: "myDiv", textContent: "this text is in the div! " });
//add link as a child to div, add the result to mainWrapper
ac(mainWrapper, ac(div, link));
div {
border: 3px solid black;
padding: 5px;
}
<div id="mainWrapper"></div>
Here is how to do specifically what you asked with more thoroughly notated code.
//get main wrapper
let mainWrapper = document.getElementById("mainWrapper");
//make a function to easily create elements
//function takes a tagName and an optional object for property values
//using Object.assign we can make tailored elements quickly.
function create(tagName, props) {
return Object.assign(document.createElement(tagName), (props || {}));
}
//document.appendChild is great except
//it doesn't offer easy stackability
//The reason for this is that it always returns the appended child element
//we create a function that appends from Parent to Child
//and returns the compiled element(The Parent).
//Since we are ALWAYS returning the parent(regardles of if the child is specified)
//we can recursively call this function to great effect
//(you'll see this further down)
function ac(p, c) {
if (c) p.appendChild(c);
return p;
}
//these are the elements you wanted to append
//notice how easy it is to make them!
//FYI when adding classes directly to an HTMLElement
//the property to assign a value to is className -- NOT class
//this is a common mistake, so no big deal!
var link = create("a", {
className: "scoreboard-video-outer-link",
url: "google.com"
});
var videoWrapper = create("div", {
className: "scoreboard-video-outer-link"
});
var videoThumbnailWrapper = create("div", {
className: "scoreboard-video--thumbnail"
});
var videoImage = create("img", {
src: "url-of-image-from-api"
});
//here's where the recursion comes in:
ac(mainWrapper, ac(link, ac(videoWrapper, ac(videoThumbnailWrapper, videoImage))));
//keep in mind that it might be easiest to read the ac functions backwards
//the logic is this:
//Append videoImage to videoThumbnailWrapper
//Append (videoImage+videoThumbnailWrapper) to videoWrapper
//Append (videoWrapper+videoImage+videoThumbnailWrapper) to link
//Append (link+videoWrapper+videoImage+videoThumbnailWrapper) to mainWrapper
let mainWrapper = document.getElementById('mainWrapper');
function create(tagName, props) {
return Object.assign(document.createElement(tagName), (props || {}));
}
function ac(p, c) {
if (c) p.appendChild(c);
return p;
}
var link = create("a", {
className: "scoreboard-video-outer-link",
url: "google.com"
});
var videoWrapper = create("div", {
className: "scoreboard-video-outer-link"
});
var videoThumbnailWrapper = create("div", {
className: "scoreboard-video--thumbnail"
});
var videoImage = create("img", {
src: "url-of-image-from-api"
});
ac(mainWrapper, ac(link, ac(videoWrapper, ac(videoThumbnailWrapper, videoImage))));
//pretty fancy.
//This is just to show the output in the log,
//feel free to just open up the developer console and look at the mainWrapper element.
console.dir(mainWrapper);
<div id="mainWrapper"></div>
Short version
Markup.js's loops.
Long version
You will find many solutions that work for this problem. But that may not be the point. The point is: is it right? And you may using the wrong tool for the problem.
I've worked with code that did similar things. I did not write it, but I had to work with it. You'll find that code like that quickly becomes very difficult to manage. You may think: "Oh, but I know what it's supposed to do. Once it's done, I won't change it."
Code falls into two categories:
Code you stop using and you therefore don't need to change.
Code you keep using and therefore that you will need to change.
So, "does it work?" is not the right question. There are many questions, but some of them are: "Will I be able to maintain this? Is it easy to read? If I change one part, does it only change the part I need to change or does it also change something else I don't mean to change?"
What I'm getting at here is that you should use a templating library. There are many for JavaScript.
In general, you should use a whole JavaScript application framework. There are three main ones nowadays:
ReactJS
Vue.js
Angular 2
For the sake of honesty, note I don't follow my own advice and still use Angular. (The original, not Angular 2.) But this is a steep learning curve. There are a lot of libraries that also include templating abilities.
But you've obviously got a whole project already set up and you want to just plug in a template into existing JavaScript code. You probably want a template language that does its thing and stays out of the way. When I started, I wanted that too. I used Markup.js . It's small, it's simple and it does what you want in this post.
https://github.com/adammark/Markup.js/
It's a first step. I think its loops feature are what you need. Start with that and work your way to a full framework in time.
Take a look at this - [underscore._template]
It is very tiny, and useful in this situation.
(https://www.npmjs.com/package/underscore.template).
const targetElement = document.querySelector('#target')
// Define your template
const template = UnderscoreTemplate(
'<a class="<%- link.className %>" href="<%- link.url %>">\
<div class="<%- wrapper.className %>">\
<div class="<%- thumbnail.className %>">\
<img src="<%- thumbnail.image %>">\
</div>\
<div class="<%- info.className %>">\
<div class="<%- info.title.className %>"><%- info.title.text %></div>\
</div>\
</div>\
</a>');
// Define values for template
const obj = {
link: {
className: 'scoreboard-video-outer-link',
url: '#someurl'
},
wrapper: {
className: 'scoreboard-video--wrapper'
},
thumbnail: {
className: 'scoreboard-video--thumbnail',
image: 'http://via.placeholder.com/350x150'
},
info: {
className: 'scoreboard-video--info',
title: {
className: 'scoreboard-video--title',
text: 'Pelicans # Bulls Postgame: E`Twaun Moore 10-8-17'
}
}
};
// Build template, and set innerHTML to output element.
targetElement.innerHTML = template(obj)
// And of course you can go into forEach loop here like
const arr = [obj, obj, obj]; // Create array from our object
arr.forEach(item => targetElement.innerHTML += template(item))
<script src="https://unpkg.com/underscore.template#0.1.7/dist/underscore.template.js"></script>
<div id="target">qq</div>

Titanium Alloy ListView Nested Model Array of Tags

I am using Titanium Alloy version 3.2. I have a collection of posts in a listview. My data looks like this:
[
{ username: 'dude', imageUrl: 'url', tags: ['tag1','tag2','tag3'] },
{ username: 'wheres', imageUrl: 'url', tags: ['tag1'] },
{ username: 'my', imageUrl: 'url', tags: ['tag1','tag2','tag3','tag4'] },
{ username: 'car', imageUrl: 'url', tags: ['tag1','tag2'] }
]
And here is the xml. This works only for username and image. I can't figure out how to add the tags to each post.
<ListView id="streamListview">
<Templates>
<ItemTemplate name="template" id="template">
<View class="item-container">
<ImageView bindId="pic" class="pic"/>
<Label bindId="username" class="username"/>
</View>
</ItemTemplate>
</Templates>
<ListSection id="section">
<ListItem template="template" class="list-item"/>
</ListSection>
</ListView>
And my controller code (without the tags)
var posts = [];
for (var i=0; i<data.length; i++){
var post = {
template : "template",
pic : { image : data[i].get("imageUrl") },
username : { text : data[i].get("username") }
};
posts.push(post);
}
$.section.setItems(posts);
How can I add tags (that are clickable) to the post if I am supposed to declare EVERY view in the template before hand? Each tags array in my example would need a different number of views depending on the array length. Each tag would ideally be its own UI.Label element. I believe this can be done using a TableView, but I would prefer using ListView for performance reasons.
I think I know what you need, in this case since you want to generate each item dynamically (for example, a scenario where you open your window with your ListView empty first and make an API call to get remote data and fill the ListView with said data) you will need to use ItemTemplates declared in their own controllers.
You just create a new controller like normal and in the view xml you put your ItemTemplate:
<Alloy>
<ItemTemplate name="template" id="template">
<View class="item-container">
<ImageView bindId="pic" class="pic"/>
<Label bindId="username" class="username"/>
</View>
</ItemTemplate>
</Alloy>
In your tss you put all of the styles referred to each element in your template, since you didn't provide a tss example I can't tell what are your style properties, but in the tss you need to define the style of the template, for example lets say something like:
"#template": // this is the id of your template in your xml
{
width : Ti.UI.FILL,
height : '44dp',
backgroundColor : '#FFFFFF'
}
To fill your ListView with ListItems dynamically, you will need to do something like this in your callback from your API:
function displayListItems(items)
{
var itemCollection = [];
for(var i=0; i < items.length; i++)
{
var tmp = {
pic : {
image : items[i].image
},
username : {
text : items[i].text
},
template : 'template' // here goes the name of the template in your xml, **do not confuse name with id, both are different and using one doesn't replace the other**
};
itemCollection.push(tmp);
}
$.ListView.sections[0].items = itemCollection;
}
And voila, you get your ListView filled dynamically. Now there are some extra steps you can do.
In your template controller you can leave it blank since the ListView can manage the itemclick event, but if you want different actions to take place when a certain element in the Listitem to trigger, you need to specify the functions to be called in your controller for each element.
For example lets say you passed a property called dataInfo to your ImageView and your Label in your template like this:
function displayListItems(items)
{
var itemCollection = [];
for(var i=0; i < items.length; i++)
{
var tmp = {
pic : {
image : items[i].image
dataInfo : items[i].fooA //lets pass to the ImageView the object fooA
},
username : {
text : items[i].text,
dataInfo : items[i].fooB //lets pass to the Label the object fooB
},
template : 'template' // here goes the name of the template in your xml, **do not confuse name with id, both are different and using one doesn't replace the other**
};
itemCollection.push(tmp);
}
$.ListView.sections[0].items = itemCollection;
}
And you want the ImageView and the Label to call different functions, you will need to change your xml like this:
<Alloy>
<ItemTemplate name="template" id="template">
<View class="item-container">
<ImageView bindId="pic" class="pic" onClick="imageFunction"/> <!-- added onClick event -->
<Label bindId="username" class="username" onClick="labelFunction"/> <!-- added onClick event -->
</View>
</ItemTemplate>
</Alloy>
In your controller you will declare each function:
function imageFunction(e)
{
var dataInfo;
if(Ti.Platform.osname === 'android')
{
var item = e.section.items[e.itemIndex];
var bindObject = item[e.bindId];
dataInfo = bindObject.fooA;
}
else
{
dataInfo = e.source.fooA;
}
}
function labelFunction(e)
{
var dataInfo;
if(Ti.Platform.osname === 'android')
{
var item = e.section.items[e.itemIndex];
var bindObject = item[e.bindId];
dataInfo = bindObject.fooB;
}
else
{
dataInfo = e.source.fooB;
}
}
Now you might ask, why do check for the operative system name, well that is because Android and iOS receive different e objects even if you use the same function. In iOS whatever property you pass to the source of the event can be accessed directly with e.source.propertyName while in Android you need to access to the item in e.section using e.itemIndex, after that you retrieve the view inside the item with the e.bindId associated to it.
One of the biggest restrictions on ListItems is updating the views inside a ListItem, to do this you need to update the whole item you want to change visually and assign it a different template, but the speed at which this is done you won't be able to notice any lag, seriously ListView's performance is something else, unlike ScrollView and let's not talk about the horrible and buggy TableView.
A warning, as of Titanium SDK 3.2.0.GA there's a bug in ItemTemplates that causes for views inside child views in the template to change their zIndex in Android with no way to control it, there are two known instances for this:
If you use a don't set the layout in a child view: this could cause for a view that should be displayed beneath another view to come on top of it.
If you use a vertical layout in a child view: this could cause for the positions of each view to be scrambled, this is because zIndex alters the order of display in a vertical layout.
This bug is triggered randomly and the Appcelerator team hasn't put much work on it, check the JIRA ticket here TIMOB-16704.
This can be avoided if you use a template with fixed positioned views and making sure no view comes on top of another, also remember no vertical layouts, haven't tested this with horizontal but personally I try to avoid horizontal layouts since there are other bugs related to it when used in scrollviews, normal views, etc.
EDIT
Another thing you might want to do with this is to assign a different look to the items you render, you have to options:
To apply the styles when you declare the ListItem.
To apply a different layout to each ListItem depending on a series of conditions.
For the first option you need to omit or overwrite the declaration of certain properties in your template:
For example, let's use a different background color where the property fooA exists and another color if it doesn't:
function displayListItems(items)
{
var itemCollection = [];
for(var i=0; i < items.length; i++)
{
var properties = {};
if(typeof items[i].fooA !== 'undefined')
{
properties = {
backgroundColor : 'red'
};
}
else
{
properties = {
backgroundColor : 'blue'
};
}
var tmp = {
properties : properties, // properties for the template
pic : {
image : items[i].image
dataInfo : items[i].fooA //lets pass to the ImageView the object fooA
},
username : {
text : items[i].text,
dataInfo : items[i].fooB //lets pass to the Label the object fooB
},
template : 'template' // here goes the name of the template in your xml, **do not confuse name with id, both are different and using one doesn't replace the other**
};
itemCollection.push(tmp);
}
$.ListView.sections[0].items = itemCollection;
}
You can change width, height, backgroundColor, layout, etc. according to your needs.
Now if you want each item to have a distinct look (meaning different views to display different content) and perhaps a different behavior, you'll need to use different templates.
This might sound bothersome but it is not, templates are fast to create once you get used to them which doesn't take long, another downer might be that if you want 11 different looks, that might mean you'll need 11 templates but that's a extreme case and you might want to rethink your UI if you're dealing with that many templates.
Although restrictive, item templates offer a wide array of options for you to use, a little of imagination is the only ingredient necessary to bring out all of the possibilities.
EDIT 2
I finally understood what was you problem, if you need to create a template whose content changes according to a x variable, then you should try declaring the template on your ListView controller, but this should be done before opening the window were you will be showing the ListView since the templates property can only be set on creation, you should add something like:
function createTemplate(items)
{
var template = {};
for(var i=0; i < items.length; i++)
{
template.childTemplates = [];
for(var j=0; items[i].tags.length; j++)
{
var childTemplate = {
type: 'Ti.UI.Label',
bindId: 'tag' + j,
properties : {
width : Ti.UI.SIZE, // Here you define how your style
height : Ti.UI.SIZE,
font : {
fontSize : '18dp'
},
text : items[i].tags[j].text // you can pass the text here or if you want to on the later for
}
};
template.childTemplates.push(childTemplate);
}
}
// After this you should end up with a template with as many childTemplates as tags each item have, so send the template to the controller with your ListView
Alloy.createController('ListViewWindow', {customTemplate: template});
}
And in your ListView controller you retrieve the template:
var args = arguments[0] || {};
var template = args.customTemplate;
$.ListView.templates = {'customTemplate' : template}; // before any window open call, do this
This should add the template to your ListView, you can also create the ListView in your controller instead of declaring it in your Alloy xml, use the one that fits your needs more.
This should be possible with a ListView if you create the template in the controller dynamically. You would also need to iterate through each "tags" object and generate a Ti.UI.Label "type" for each tag item. However, I'm not certain this method will be more efficient than using a TableView object because essentially every ListItem you create will contain a different template.
To generate a dynamic template it would be similar to this below: Keep in mind you will need to iterate over "tags" and generate x Ti.UI.Label types where x is the length of "tags". Also, the click event should work using Titanium SDK 3.2.1.
var plainTemplate = {
childTemplates: [
{
type: 'Ti.UI.Label',
bindId: 'username'
},
{
type: 'Ti.UI.ImageView',
bindId: 'pic'
},
{
type: 'Ti.UI.Label',
bindId: 'tags',
events: { click : handleTagClickEvent } // Binds a callback to click event
}
]};
function handleTagClickEvent(e) {
Ti.API.info('You clicked a tag label: ' + e.type);
}
var listView = Ti.UI.createListView({
templates: { 'plain': plainTemplate },
defaultItemTemplate: 'plain'
});
Hope this helps you in some way!

How to translate a html into different languages in MS CRM 2011?

I have created one Html for ms crm 2011, this is in English language.But i want to show the same html in other languages(Arabic,Spanish..etc ) for some users, how i can achieve this,is there any traslating api ?
Unfortunately there are not translating API. All you can do is to create a separated webresource for every language you want to support and show webresource based on the language of current user.
No OOB functionality exists unfortunately, but it's not as hard as it seems to implement in JS.
All you need is a container with your labels, CRM can tell you the user's language. The script would look like this (taken right out of a working project, which also leverages jQuery ... if you don't, just add it as webresource and include in your HTML page):
(function (pageCode, $, undefined) {
var labels = {
1033: {
element1: 'english label for element1',
element2: 'eng label for element2'
},
1040: {
element1: 'italian label for element1',
element2: 'italian label for element2'
},
xxxx: {
element1: 'xxxx language label for element1',
element2: 'xxxx language label for element2'
}
}
pageCode.performTranslation = function() {
var langCode = Xrm.Page.context.getUserLcid();
if (typeof (locLabels[langCode]) == 'undefined') {
// You don't have labels for this language... let's go English
langCode = 1033;
}
for (var ctrlName in locLabels[langCode]) {
$('#' + ctrlName).text(locLabels[langCode][ctrlName]);
}
}
}(window.pageCode = window.pageQuote || {}, jQuery));
$(function(){
pageCode.performTranslation();
});
You'll need to include ClientGlobalContext.js.aspx in your web resource so you have access to Xrm, and change what your HTML code looks like in this fashion:
If your HTML is now
<label>This is a label</label>
<label>This is another label</label>
You should give an id to all the translated elements, and the code should become
<label id="element1"></label>
<label id="element2"></label>
Note that you no longer need to fill the text in the HTML (the JS will take care of it!).
