Dojo Javascript variable scope - javascript

I am using dgrid and i am attempting to set the dataStore externally. When the page loads i call aliasTicket.load() to create the grid. At the time the grid is loading the datasource is null. When a query is executed the setAliasSource(aliasData); is set.
There are no errors however the grid is still empty. The aliasStore is being updated with data however it isn't being reflected on the grid even after the grid is refreshed. How can i get the data reflected in the grid after the query?
Javascript Object
var aliasTicket = (function (){
var aliasData = [];
require([ "dojo/store/Observable", "dojo/store/Memory"]);
var aliasStore = new dojo.store.Observable(new dojo.store.Memory({
data: aliasData,
idProperty: "id"
}));
return{
load:function(){
require([
........
], function(declare, Memory, OnDemandGrid, ColumnSet, Selection,
selector, Keyboard, DijitRegistry, editor, ColumnHider,
registry, Observable,lang) {
aliasData = this.aliasData;
var Store = this.aliasStore = new dojo.store.Observable(new dojo.store.Memory({
data: aliasData,
idProperty: "id"
}));
console.log(Store);
var CustomAliasNameGrid = declare([OnDemandGrid, selector, Selection, Keyboard, editor, DijitRegistry, ColumnHider]);
var aliasNameGrid = new CustomAliasNameGrid({
store: Store,
columns: {
id: {
label: "Id",

return str.replace(/\w\S*/g, function(txt) {
return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
});
}
}
},
selectionMode: "none",
loadingMessage: "Loading data...",
noDataMessage: "No results found....",
allowSelectAll: true
}, "aliasNameGrid");
aliasNameGrid.refresh()
});
},
setAliasSource: function (data){
console.log(data);
this.aliasSource = data;
},
setAliasData: function (data){
this.aliasData = data;
},
getAliasSource: function (){
return this.aliasSource;
}
};
})();
Setting Data Store Data
aliasData = [{.....},
{.....},
{......];
require(["dijit/dijit"]);
aliasTicket.setAliasSource(aliasData);
dijit.byId('aliasNameGrid').refresh();

You are setting 'this.Store' to an object array, not a real 'dojo store' object. Following your code I can not see where you actually use 'this.Store'. Inside the grid code I do see a local variable named 'Store'.
So I'm not sure if I'm following your code example here but, you should 'set' the store of the grid and then refresh it. Something like this.
setAliasSource: function (data){
console.log(data);
this.Store = data;
dijit.byId('aliasNameGrid').set("store",new dojo.store.Observable(new dojo.store.Memory({ data: data,idProperty: "id"}));
dijit.byId('aliasNameGrid').refresh();
},

How Do I Enable Filter Functions in CA Agile Central?

I need to employ a filter function to implement a heuristic for selecting records. Simple field/value checks, alone, are inadequate for our purpose.
I'm trying to follow the examples for function filters, but for some reason, the "allowFunctions" flag keeps getting set to false.
I attempt to set the allowFunctions property to true in the storeConfig:
storeConfig: {
models: ['userstory', 'defect'],
allowFunctions: true,
filters: [{
// This did not work ...
property: 'Iteration.Name',
value: 'Sprint 3',
// Trying dynamic Filter Function. Update: Never called.
filterFn: function (item) {
console.log("Entered Filter Function!");
var iter = item.get("Iteration");
console.log("Iteration field: ", iter);
if (iter !== null && iter !== undefined) {
return (iter.name === "Sprint 3");
} else {
return false;
}
}
}]
},
After the grid view renders, I inspect it the store configuration and its filters:
listeners: {
afterrender: {
fn: function (_myVar, eOpts) {
console.log("Arg to afterrender: ", _myVar, " and ", eOpts);
var _myStore = _myVar.getStore();
console.log("Store filters: ", _myStore.filters);
}
}
},
What I find is that the allowFunctions property has been set back to false and I see that the filter function I specified never fired.
Console Screen Shot
So either I am setting allowFunctions to true in the wrong place, or something built into the Rally Grid View and its data store prohibits filter functions and flips the flag back to false.
OR there's a third option betraying how badly off my theory of operation is.
Oh, wise veterans, please advise.
Here's the entire Apps.js file:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function () {
//Write app code here
console.log("Overall App Launch function entered");
//API Docs: https://help.rallydev.com/apps/2.1/doc/
}
});
Rally.onReady(function () {
Ext.define('BOA.AdoptedWork.MultiArtifactGrid', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function () {
console.log("onReady Launch function entered");
this.theGrid = {
xtype: 'rallygrid',

console.log("Arg to afterrender: ", _myVar, " and ", eOpts);
var _myStore = _myVar.getStore();
console.log("Store filters: ", _myStore.filters);
}
}
},
storeConfig: {
models: ['userstory', 'defect'],
allowFunctions: true,
filters: [{
// This did not work ...
property: 'Iteration.Name',
value: 'Sprint 3',
// Trying dynamic Filter Function. Update: Never called.
filterFn: function (item) {
console.log("Entered Filter Function!");
var iter = item.get("Iteration");
console.log("Iteration field: ", iter);
if (iter !== null && iter !== undefined) {
return (iter.name === "Sprint 3");
} else {
return false;
}
}
}]
},
context: this.getContext(),
scope: this
};
this.add(this.theGrid);
console.log("The Grid Object: ", this.theGrid);
}
});
Rally.launchApp('BOA.AdoptedWork.MultiArtifactGrid', {
name: 'Multi-type Grid'
});
});
This is a tricky one since you still want your server filter to apply and then you want to further filter the data down on the client side.
Check out this example here:
https://github.com/RallyCommunity/CustomChart/blob/master/Settings.js#L98
I think you can basically add a load listener to your store and then within that handler you can do a filterBy to further filter your results on the client side.
listeners: {
load: function(store) {
store.filterBy(function(record) {
//return true to include record in store data
});
}
}
I'm not familiar with allowFunctions, but in general remoteFilter: true/false is what controls whether the filtering is occurring server side or client side. remoteFilter: true + the load handler above gives you the best of both worlds.

Updating server from Kendo Color picker inside kendo grid

The Problem
So i am currently trying to implement a color picker inside of a Kendo grid, that will hopefully send the chosen color to my Sql Table. Unfortunately, It doesn't seem as though the Update controller is being reached. I am relatively new to Kendo UI, so there might be some incredibly dumb errors shown.
Questions
I guess my main question would be: How can i call the update method when update is clicked on the grid. Essentially, the color picker and the edit command are showing up in beautiful fashion. I just want to know how i can be sure that the method is being called when 'Update' is clicked, seeing as it is not reaching my controller. Feel free to ask if you need to see more code or perhaps a screen shot.
Code
Config.cshtml ( Grid )
#model IEnumerable<STZN.Models.AGCData.ErrorCode>
#{
ViewBag.Title = "Config";
}
#section HeadContent{
<script src="~/Scripts/common.js"></script>
<script>
$(document).ready(function () {
$("#grid").kendoGrid({
editable: "inline",
selectable: "row",
dataSource: {
schema: {
model: {
id: "error_code",
fields: {
color: { type: 'string' }
}
}
},
transport: {
read: {
type: "POST",
dataType: "json",
url: "#Url.Action("ErrorCodes")"
},
update: {
type: "POST" ,
dataType: "json",

}
}
},
columns: [
{ command : [ "edit" ] },
{
field: "error_code", title: "Error Code",
},
{
field: "error_description", title: "Error Description"
},
{
field: "color",
width: 150,
title: "Color",
template: function (dataItem) {
return "<div style = 'background-color: " + dataItem.color + ";' </div>"
},
editor: function (container, options) {
var input = $("<input/>");
input.attr("color",options.field);
input.appendTo(container);
input.kendoColorPicker({
value: options.model.color,
buttons: false
})
},
}
]
});
});
</script>
}
Update Controller
public JsonResult UpdateErrorCodes(ErrorCode model)
{
using (var db = new AgcDBEntities())
{
db.Entry(model).State = System.Data.Entity.EntityState.Modified;
db.SaveChanges();
db.Configuration.ProxyCreationEnabled = false;
var data = db.ErrorCodes.Where(d => d.error_code == model.error_code).Select(x => new
{
error_code = x.error_code,
description = x.error_description,
color = x.color,
});
return new JsonResult()
{
JsonRequestBehavior = System.Web.Mvc.JsonRequestBehavior.AllowGet,
};
}
}
I actually managed to fix my issue by adding an additional input attribute to my editor function in the "color" field. It looks like this:
input.attr("data-bind","value:" + options.field);
There are still some present issues (unrelated to the fix/server update) , but as far as updating to the server, It work's as intended.

Selectize: Setting Default Value in onInitialize with setValue

I have a web application with multiple Selectize objects initialized on the page. I'm trying to have each instance load a default value based on the query string when the page loads, where ?<obj.name>=<KeywordID>. All URL parameters have already been serialized are are a dictionary call that.urlParams.
I know there are other ways to initializing Selectize with a default value I could try; but, I'm curious why calling setValue inside onInitialize isn't working for me because I'm getting any error messages when I run this code.
I'm bundling all this JavaScript with Browserify, but I don't think that's contributing to this problem.
In terms of debugging, I've tried logging this to the console inside onInititalize and found that setValue is up one level in the Function.prototype property, the options property is full of data from load, the key for those objects inside options corresponds to the KeywordID. But when I log getValue(val) to the console, I get an empty string. Is there a way to make this work or am I ignoring something about Selectize or JavaScript?
module.exports = function() {
var that = this;
...
this.selectize = $(this).container.selectize({
valueField: 'KeywordID', // an integer value
create: false,
labelField: 'Name',
searchField: 'Name',
preload: true,
allowEmptyOptions: true,
closeAfterSelect: true,
maxItems: 1,
render: {
option: function(item) {
return that.template(item);
},
},
onInitialize: function() {
var val = parseInt(that.urlParams[that.name], 10); // e.g. 5
this.setValue(val);
},
load: function(query, callback) {
$.ajax({
url: that.url,
type: 'GET',
error: callback,
success: callback
})
}
});
};
...
After sprinkling in some console.logs into Selectize.js, I found that the ajax data hadn't been imported, when the initialize event was triggered. I ended up finding a solution using jQuery.when() to make setValue fire after the data had been loaded, but I still wish I could find a one-function-does-one-thing solution.
module.exports = function() {
var that = this;
...
this.selectize = $(this).container.selectize({
valueField: 'KeywordID', // an integer value
create: false,
labelField: 'Name',
searchField: 'Name',
preload: true,
allowEmptyOptions: true,
closeAfterSelect: true,
maxItems: 1,
render: {
option: function(item) {
return that.template(item);
},
},
load: function(query, callback) {
var self = this;
$.when( $.ajax({
url: that.url,
type: 'GET',
error: callback,
success: callback
}) ).then(function() {
var val = parseInt(that.urlParams[that.name], 10); // e.g. 5
self.setValue(val);
});
}
});
};
...
You just need to add the option before setting it as the value, as this line in addItem will be checking for it:
if (!self.options.hasOwnProperty(value)) return;
inside onInitialize you would do:
var val = that.urlParams[that.name]; //It might work with parseInt, I haven't used integers in selectize options though, only strings.
var opt = {id:val, text:val};
self.addOption(opt);
self.setValue(opt.id);
Instead of using onInitialize you could add a load trigger to the selectize. This will fire after the load has finished and will execute setValue() as expected.
var $select = $(this).container.selectize({
// ...
load: function(query, callback) {
// ...
}
});
var selectize = $select[0].selectize;
selectize.on('load', function(options) {
// ...
selectize.setValue(val);
});
Note that for this you first have to get the selectize instanze ($select[0].selectize).
in my case it need refresh i just added another command beside it
$select[0].selectize.setValue(opt);
i added this
$select[0].selectize.options[opt].selected = true;
and changes applied
but i dont know why?
You can initialize each selectize' selected value by setting the items property. Fetch the value from your querystring then add it as an item of the items property value:
const selectedValue = getQueryStringValue('name') //set your query string value here
$('#sel').selectize({
valueField: 'id',
labelField: 'title',
preload: true,
options: [
{ id: 0, title: 'Item 1' },
{ id: 1, title: 'Item 2' },
],
items: [ selectedValue ],
});
Since it accepts array, you can set multiple selected items

ExtJS property grid reload after render

I have a property grid :
periods.each(function(record){
var tempPropGrid = me.getView().add(
{
xtype:'propertygrid',
width: 80,
header: false,
title: 'prop grid',
//for some reason the headers are not hiding, we may need to deal with this using CSS
//hideHeaders: true,
enableColumnResize: false,
sortableColumns: false,
nameColumnWidth: 1,
source: record.data,
sourceConfig: {
periodScrumMaster: {
editor: Ext.create('Ext.form.ComboBox', {
tdCls: 'red',
store: team,
queryMode: 'local',
displayField: 'personName',
valueField: 'personName',
listeners: {
'expand' : function(combo) {
var gridvalues = this.up('propertygrid').getSource();
combo.getStore().clearFilter(true);
combo.getStore().addFilter({property: 'teamName', value: teamName});
combo.getStore().addFilter({property: 'periodName', value: gridvalues.periodName});
var totalFTE = team.count();
console.log(totalFTE);
var teamStore = Ext.getStore('personPeriods');
console.log('store');
console.log(teamStore);
},
}}),
displayName: 'Scrum Master'
},
},
That has a render listener:
beforerender: function(){
debugger;
var gridValues = this.getSource();
// console.log(record);
//debugger;
// filter periods for this period only
periods.filterBy(function(record,id){
if(record.get("periodName") === gridValues.periodName){
return true;
}});
// filter teamMembers for this period and team
var view = this.up();
var vm = view.getViewModel();
var store = vm.getStore('teamMembers');
store.filterBy(function(record,id){
if(record.get("periodName") === gridValues.periodName) {
return true;
}});
//store.clearFilter(true);
store.addFilter({property: 'teamName', value: teamName});
// get FTEs assigned to this team in this period by counting records
var resourcedFtes = store.count();
// Here I check the record in the periods store to make sure the data matches up with how many resourcedFte there is an update it if required
// This is super bad and will need to refactor
periods.each(function(record,idx){
var value = record.get('resourcedFte');
if(value != resourcedFtes){
record.set('resourcedFte',resourcedFtes);
record.commit();
vm.data.parentController.saveParent();
}});
// Need to call save parent so that the record is updated when we update it above
//Clear everything so that we can start fresh next period
store.clearFilter(true);
//periods.clearFilter(true);
Basically there is some logic to check if the data is correct/up to date and if its not it updates it. This works fine, but the data is not then loaded into the grid. I have to refresh after rendering the grid for it to load correctly.
Is there a way I can call a refresh or reload method on the property grid to load the data again inside an if statement?
If I understand your question, I would suggest you to programm the store proxy so that it returns the whole changed record.
Is your store parametered with autoLoad enabled?
(sorry I can't (yet) comment)

Consume WCF crossdomain using JSONP to store in datagrid and view data dojo?

I can't find this anywhere and i don't know why the cross domain REST request is not solved by dojo. anyways here is the problem:
I am implementing dojo data-grid, and i am trying to get the data for the grid from a WCF that is not in my domain, so i crossdomain problem is raised and i am trying to over come this problem by using JSONP.
but i am a newbie in dojo so i am probably doing something wrong. here is my code:
require([
"dojo/store/JsonRest",
"dojo/store/Memory",
"dojo/store/Cache",
"dojox/grid/DataGrid",
"dojo/data/ObjectStore",
"dojo/query",
"dijit/form/Button",
"dojo/domReady!",
"dojo/request/script","dojo/dom-construct"
],function(script, domConstruct){
//make the request just as before
script.get("http://localhost:8060/ListService.svc/LoadLists?uid=c4446476-15e6-e111-9ecb-b7c5971d170a", {
jsonp: "callback",
query: {q: "#dojo"}
}).then(function(data){
test = data;
}).then(function(){
console.log(results);
});
}, function (JsonRest, Memory, Cache, DataGrid, ObjectStore ,query) {
grid = new DataGrid({
store: dataStore = test,
structure: [
{ name: "Blog Id", field: "id", width: "50px", },
{ name: "Name", field: "listtype", width: "200px",classes:"Name" },
{ name: "Phone Number", field: "longlevel", width: "200px",classes:"test" }
]
}, "gridTest"); // make sure you have a target HTML element with this id
grid.startup();
dojo.query("body").addClass("claro");
grid.canSort = function () { return false; };
});
the error i am getting is query is not a function. any ideas how to implement this correctly.
Simple mistake just put the data grid command inside the first then with the data returning
require([
"dojo/store/JsonRest",
"dojo/store/Memory",
"dojo/store/Cache",
"dojox/grid/DataGrid",
"dojo/data/ObjectStore",
"dojo/query",
"dijit/form/Button",
"dojo/domReady!",
"dojo/request/script","dojo/dom-construct"
],function(script, domConstruct){
//make the request just as before
script.get("http://localhost:8060/ListService.svc/LoadLists?uid=c4446476-15e6-e111-9ecb-b7c5971d170a", {
jsonp: "callback",
query: {q: "#dojo"}
}).then(function(data){
function (JsonRest, Memory, Cache, DataGrid, ObjectStore ,query) {
grid = new DataGrid({
store: dataStore = test,
structure: [
{ name: "Blog Id", field: "id", width: "50px", },
{ name: "Name", field: "listtype", width: "200px",classes:"Name" },
{ name: "Phone Number", field: "longlevel", width: "200px",classes:"test" }
]
}, "gridTest"); // make sure you have a target HTML element with this id
grid.startup();
dojo.query("body").addClass("claro");
grid.canSort = function () { return false; };
})
}).then(function(){
console.log(results);
});
};
If you still find a problem probably because the grid is created before the request is returning from the wcf.
if that happened please use the Deferred in dojo 1.8 which make you in control of you processes sequence.
so you will be able to call the request give it some time and then put the data in the grid to be viewed.
