I am having a very big form which has lot of form columns.
I am putting my form data using this code :
var formData = {};
$("#newwaitlist div").children().each(function(i, el){
formData[el.id] = $(el).val();
});
var waitdriver= new DriverWaitModel(formData);
console.log(JSON.stringify(waitdriver));
this.collection.add(waitdriver);
The data is correctly getting taken.
but i am having a small bug in this.
Inside my form i also have my buttons and also form that takes options(like drop downs).
The above code also logs the button value and its id. Is there a way to remove it before adding to the collection ??
IS the way i am passing my data to the collection correct ?? or is there a better way of doing the same ??
Note
I cannot use backbone-stickit or anyother .. Just with backbone, underscore and jquery we have to do. So ...
You could just do a check for the type, as in el.prop('type'). Like this:
$("#newwaitlist div").children().each(function(i, el) {
if (el.prop('type') !== 'button') {
formData[el.id] = $(el).val();
}
});
The above answer also solved the problem,
But in my case i had also to filter out some form elements that were also of not button type.
So this is how i made it work;
if(el.id!="addDriveBtn"===true){
formData[el.id] = $(el).val();
}
which ever id you dont want to input you can just filter out.
Worked great...
JavaScript and Backbone just rocks

I've been working with Liferay 7 for a while and needed to create a feedback form with prefilled values. I created a feedback form and a page, where it's shown and where I could add Javascript.
The user clicks on a link ("Did you find this helpful? Yes/No") and it takes you to the feedback page with the page and answer as URL parameters.
URL: {feedback-page-url/} ?pageUrl=/services&answer=Yes
Now here's where the problems began. Liferay updates it's values very confusingly and while generic document.getElementsByName(...) etc. seemed to work at first, they updated back when clicking the page. The difficult thing is to update the right values in right elements, so they won't be overrun by Liferay.
I provided an answer to my question below. Feel free to ask me anything, I'll try to help :)
Full code block in the end!
So I found out a solution to this problem. Liferay creates an instance (_com_liferay...) and uses it's values to be up to date, so we need to get a hold of it and update it's values. You can do it manually by inspecting and finding your instance, but I have an automatic code that should get it for you.
The id we are searching for is for DDMFormPortlet and the String we get this way is close to perfect. The String that document.querySelector() finds begins with p_p_id_com..., so we can use .substring to remove the unnecessary part and then add +"form" in the end to make it complete. If you find a better way to find this, please share it :)
// _com_liferay_dynamic_data_mapping_form_web_portlet_DDMFormPortlet_INSTANCE_randomkey_form
const idFinder = function() {
const idString = document.querySelector('[id*="DDMFormPortlet"]').id;
return(idString.substring(6) + "form");
}
Now that we have the correct String text, we'll find the element, that corresponds to it:
const formFieldArray = window[idFinder()];
Now if you try it just by itself, it most likely won't find anything, because it's loads slowly. I put all of this into try-catch with setTimeout() to make sure everything works as intended. Now all we need to do is collect the information from our URL and set it to the correct places.
const params = new URLSearchParams(location.search);
const formAutoFiller = function (params) {
try {
const formFieldArray = window[idFinder()];
// make sure you have the numbers according to your form!
formFieldArray.pages[0].rows[0].columns[0].fields[0].value=params.get('pageUrl');
formFieldArray.pages[0].rows[1].columns[0].fields[0].value=params.get('answer');
// ...
}
}
And finally, as the changed values update to the form after clicking an input field, we'll move the selection focus to one of the input fields after the other code is ran:
document.getElementsByClassName("ddm-field-text")[1].focus();
A bit cleanup for myself and we're done! Full Javascript here:
const params = new URLSearchParams(location.search);
const idFinder = function() {
const idString = document.querySelector('[id*="DDMFormPortlet"]').id;
return(idString.substring(6) + "form");
}
const formAutoFiller = function (params) {
try {
const formFieldRows = window[idFinder()].pages[0].rows;
formFieldRows[0].columns[0].fields[0].value=params.get('pageUrl');
formFieldRows[1].columns[0].fields[0].value=params.get('answer');
document.getElementsByClassName("ddm-field-text")[1].focus();
} catch (e) {
setTimeout(formAutoFiller, 500, params);
}
}
formAutoFiller(params);
Here is a drop down list in SmartClient: http://www.smartclient.com/#dropdownGrid.
I want to make a selection using JavaScript. Like, I run some JavaScript in console, and the drop list will select a specific item.
I did some research, found a code snap to do this (the code is in Java, but I think there should be similar functions in JavaScript):
Record rec = perdomainGrid.getRecordList().find("domaine_id", domaine_id);
perdomainGrid.selectSingleRecord(rec);
If I want to make selection, first I need to obtain perdomainGrid object. In my above giving link, the drop down list id in GWT is exampleForm (can be seen in dropDownGrid.js tab). I try to get the object by:
var form = isc.DynamicForm.getById("exampleForm");
form does exist, but there is no getRecordList() function on it, there is selectSingleRecord() function on it though.
I try to check form's class by form.className, its value is normal. I don't know what does that mean.
I'm kind of confused now. Could somebody help me on this?
isc_SelectItem_5 has a function called pickValue(), it takes one parameter SKU. This function can be used to select item.
var itemName = "Letter Tray Front Load Tenex 200 Class Blk #23001";
var data = isc_SelectItem_5.optionDataSource.cacheData;
var targetSKU = data.find(function(e) {
if (e.itemName == itemName) {
return e;
}
}).SKU;
isc_SelectItem_5.pickValue(targetSKU);
I've built an app that is form-based. I want to enable users to partially fill out a form, and then come back to it at a later date if they can't finish it at the present. I've used iron router to create a unique URL for each form instance, so they can come back to the link. My problem is that Meteor doesn't automatically save the values in the inputs, and the form comes up blank when it is revisited/refreshes. I tried the below solution to store the data in a temporary document in a separate Mongo collection called "NewScreen", and then reference that document every time the template is (re)rendered to auto fill the form. However, I keep getting an error that the element I'm trying to reference is "undefined". The weird thing is that sometimes it works, sometimes it doesn't. I've tried setting a recursive setTimeout function, but on the times it fails, that doesn't work either. Any insight would be greatly appreciated. Or, if I'm going about this all wrong, feel free to suggest a different approach:
Screens = new Meteor.Collection('screens') //where data will ultimately be stored
Forms = new Meteor.Collection('forms') //Meteor pulls form questions from here
NewScreen = new Meteor.Collection('newscreen') //temporary storage collection
Roles = new Meteor.Collection('roles'); //displays list of metadata about screens in a dashboard
//dynamic routing for unique instance of blank form
Router.route('/forms/:_id', {
name: 'BlankForm',
data: function(){
return NewScreen.findOne({_id: this.params._id});
}
});
//onRendered function to pull data from NewScreen collection (this is where I get the error)
Template.BlankForm.onRendered(function(){
var new_screen = NewScreen.findOne({_id: window.location.href.split('/')[window.location.href.split('/').length-1]})
function do_work(){
if(typeof new_screen === 'undefined'){
console.log('waiting...');
Meteor.setTimeout(do_work, 100);
}else{
$('input')[0].value = new_screen.first;
for(i=0;i<new_screen.answers.length;i++){
$('textarea')[i].value = new_screen.answers[i];
}
}
}
do_work();
});
//onChange event that updates the NewScreen document when user updates value of input in the form
'change [id="on-change"]': function(e, tmpl){
var screen_data = [];
var name = $('input')[0].value;
for(i=0; i<$('textarea').length;i++){
screen_data.push($('textarea')[i].value);
}
Session.set("updateNewScreen", this._id);
NewScreen.update(
Session.get("updateNewScreen"),
{$set:
{
answers: screen_data,
first: name
}
});
console.log(screen_data);
}
If you get undefined that could mean findOne() did not find the newscreen with the Id that was passed in from the url. To investigate this, add an extra line like console.log(window.location.href.split('/')[window.location.href.split('/').length-1], JSON.stringify(new_screen));
This will give you both the Id from the url and the new_screen that was found.
I would recommend using Router.current().location.get().path instead of window.location.href since you use IR.
And if you're looking for two way binding in the client, have a look at Viewmodel for Meteor.
I know this will probably a simple question, but I'm new to CQ5 and AEM in general.
I have a cq:Widget node which is a simple textfield.
<rowtitlevalue
jcr:primaryType="cq:Widget"
fieldLabel="Row Title Value"
name="./rowtitlevalue"
xtype="textfield"
disabled="true"/>
Now at the moment within my JavaScript, I'm currently accessing it via
var textfield = panel.findByType('textfield')[1];
which works fine (there's another textfield before this one, hence the 1 in the array.
MY QUESTION:
how do I look for this field using it's NAME attribute within my javascript.
Any help would be appreciated.
Also, I'm using this object to run the following:
if (show != undefined) {
textfield.enable();
textfield.show();
}
else if (show == undefined) {
textfield.disable();
textfield.hide();
}
The JavaScript is located within the Component Based ClientLibs.
And this is the Listener that I have under the checkbox that defines the value of SHOW within the javascript (which is working fine).
<listeners
jcr:primaryType="nt:unstructured"
loadcontent="function(field,rec,path){Ejst.toggleRowTitle(field);}"
selectionchanged="function(field,value){Ejst.toggleRowTitle(field);}"/>
Please let me know if you see any problems with this.
Appreciate it in advance
The CQ.Dialog API defines the getField( String name) method which returns a field with the given name. In case more than one field with the same name exists, it returns an array of those fields.
Thus finding parent of xtype dialog instead of panel as shown below would solve this.
Ejst.toggleRowTitle = function(checkbox) {
var dlg = checkbox.findParentByType('dialog');
var rowTitleField = dlg.getField('./rowtitlevalue');
// perform required operation on rowTitleField
}
i did something like that a few days ago and my solution was to make a js file on the same level of the component and with the same name of the component with the information that i need.
Something like this:
The file will be called rowtitlevalue.js and the content would be:
"use strict";
use(function() {
var data = {};
data.rowtitlevalueData = properties.get("rowtitlevalue");
//more properties if needed...
return {
data: data
}
});
then where i need to use it in javascript, i need the following tags:
<sly data-sly-use.data="rowtitlevalue.js">
<script type="text/javascript">
var myVariable = ${data.rowtitlevalueData};
</script>
</sly>
(there are other questions but neither helped me out)
Hi, I would like to know if this is the right way to filter the results I get from service where I'm displaying only one result (like a detail).
I know I could use ng-repeat and filter it in the view and that is the cleanest, but I want to have more control over because I will re-use some of the data in the controller for other operations.
Right now I'm doing this:
$scope.savedEvents = Event.getPayedEvents(); //gets a list from service
//Goes through entire list and checks for a match
angular.forEach($scope.savedEvents, function(event) {
if (event.IdEvent == $stateParams.eventId) {
$scope.showEvent = event;
}
});
//now if there is a match I can use $scope.showEvent.eventName etc
Not sure if this would be easier using $filter to return just one event that has correct IdEvent. Or if someone has better solution, please let me know.
thanks
I don't see any problems with what you have, but you could inject the $filter service and do this one liner:
$scope.showEvent = $filter('filter')($scope.savedEvents, { IdEvent: $stateParams.eventId });
EDIT: Here is an easy way to resolve the result to a single value from the returned array:
var showEvents = $filter('filter')($scope.savedEvents, { IdEvent: $stateParams.eventId });
$scope.showEvent = showEvents && showEvents.length ? showEvents[0] : null;
In CoffeeScript it is a little more concise:
$scope.showEvent = $filter('filter')($scope.savedEvents, { IdEvent: $stateParams.eventId })?[0]
