Not sure what wrong I am doing, but I have followed the apparoch explained. I think, I am also getting the objects added into store object. but the same is not getting reflected on UI. the drop down is still blank. can sombody please help.
My Select box code:
<div class="ecmSearchFormInputArea">
<table class="ecmSearchFormInputArea">
<tr>
<td class="propertyRowLabel">
<label><span class="mandatory_red"></span>Cost Center :</label>
<select data-dojo-attach-point="costCenter" id="costCenter"
data-dojo-type="dijit/form/FilteringSelect" style="width: 18em;"
data-dojo-attach-event="onChange:loadDocStacks">
</select>
</td>
</tr>
</table>
</div>
My JS
postCreate: function() {
this.logEntry("postCreate");
//Trying to populate Combobox
var storeData = {
identifier: 'costCenter',
items: []
}
var jsonObj = [{
costCenter: 'sc1'
},
{
costCenter: 'sc2'
}]
dojo.addOnLoad(function () {
var costCenterStore = new dojo.data.ItemFileWriteStore({ data: storeData });
for (var i = 0; i < jsonObj.length; i++) {
alert ("value of i = " + jsonObj[i].costCenter);
costCenterStore.newItem(jsonObj[i]);
}
var serviceFilterSelect = dijit.byId('costCenter');
alert ("serviceFilterSelect " + serviceFilterSelect);
alert ("costCenterStore " + costCenterStore);
serviceFilterSelect.attr('store', costCenterStore);
});
//Trying to populate Combobox
this.logExit("postCreate");
},
Alerts in the FOR loop shows correct data. Am I missing anything?
add label attribute along with the identifier. Because that is what will be used as label to populate.
var jsonObj = [{
costCenter: 'sc1', name: 'label1'
},
{
costCenter: 'sc2', name: 'label2'
}];
var storeData = {
identifier: 'costCenter', label: 'name',
items: []
};

I'll try to simplify the problem as much as I can.
Let's say I have 2 scopes
$scope.section1 = [
{label: 'label1'},
{label: 'label2'}
];
$scope.section2 = [
{value: 'one'},
{value: 'two}
];
Those scopes are used to generate buttons with ng-repeat
<button ng-repeat="item in section1 type="button">{{item.label}}</button>
and
<button ng-repeat="item in section2 type="button">{{item.value}}</button>
Now what I would like to do it to create a third scope that would attach values to the combinations of objects from the two previous ones, say:
$scope.combo = [
{ section1.label:label1 + section2.value: one = 'result1' },
{ section1.label:label2 + section2.value: one = 'result2' },
{ section1.label:label1 + section2.value: two = 'result3' },
{ section1.label:label2 + section2.value: two = 'result4' }
];
Now here comes the tricky part. What I would need to do, is to add a function that would take the values of clicked ng-repeat buttons from each section and then display the results based on the third scope in an input field or something.
So, if you click the button with label:label1 and the one with value:two the input field would show result3.
I'm very green when it comes to Angular and I have no idea how to approach it, especially that all values are strings.
If I understand correctly you could setup your combo something like ...
$scope.combo = {
"label1": {
"one": "result1",
"two": "result2"
},
"label2": {
"one": "result3",
"two": "result4"
}
}
You can then reference the correct value as combo[valueFromButton1][valueFromButton2] where valueFromButton1 and valueFromButton2 point at a model that contains the result of the clicked buttons. Your controller function then just needs to tie everything together by updating the model when the buttons are clicked.

Without changing much you can also try like below provided code snippet.Run it to check the demo.
var app = angular.module('app', []);
app.controller('Ctrl',['$scope' ,function($scope) {
var key1, key2;
$scope.click = function(type, item) {
if (type == 'label') {
key1 = item;
} else if (type == 'val') {
key2 = item;
}
$scope.key = key1 + '+' + key2;
angular.forEach($scope.combo, function(val, key) {
if(val[$scope.key]){
$scope.finalVal = val[$scope.key];
}
});
};
$scope.section1 = [{
label: 'label1'
}, {
label: 'label2'
}];
$scope.section2 = [{
value: 'one'
}, {
value: 'two'
}];
$scope.combo = [{
'label1+one': 'result1'
}, {
'label2+one': 'result2'
}, {
'label1+two': 'result3'
}, {
'label2+two': 'result4'
}];
}]);

var dataSource = ko.observableArray([]);

How to get 'name' and 'check' values inside save function,Devextreme mobile?
You just can use the dataSource array.
var save = function () {
var items = dataSource();
console.log(items[0].name + " - " + items[0].check());
console.log(items[1].name + " - " + items[1].check());
};
If you want to get only checked items, you can use the jQuery.grep function to filter data.
var items = $.grep(dataSource(), function(item){
return item.check() === true;
});
Also, I suggest you use the ko.observable() to define the check field of items. It allows you to track changes of the check field.

In this plunk I have an empty grid (without columns). When I click on "Build Grid" I need to add columns (taken from an array) and also add a row to the table.
The problem is that the columns are not added to the grid, any ideas? If I try to refresh the grid, I get an undefined error.
HTML:
<button ng-click="buildGrid()">Build Grid</button>
<div kendo-grid="grid" k-options="gridOptions" k-data-source="ds"></div>
Javascript:
var app = angular.module("app", [ "kendo.directives" ]);
function MyCtrl($scope) {
$scope.ds = []
$scope.colsList = [{ name: "col1" },
{ name: "col2" },
{ name: "col3" },
{ name: "col4" }];
var gridCols = [];
$scope.gridOptions = {
columns: gridCols
};
$scope.buildGrid = function() {
$scope.data = {};
for (var x=0;x<$scope.colsList.length;x++) {
var col = {};
col.field = $scope.colsList[x].name;
col.title = $scope.colsList[x].name;
$scope.data[col.field] = "" + (1111 * (x+1));
gridCols.push(col);
}
// add one row to the table
$scope.ds.push($scope.data);
//$scope.grid.refresh();
};
}
You need to use k-rebind so that the grid reinitializes (you can't set the columns dynamically on an existing grid):
<div kendo-grid="grid"
k-options="gridOptions"
k-data-source="ds"
k-rebind="gridOptions"></div>

I have a select2 drop down with the following markup:
<select id="selectByName" ui-select2="select2Options" ng-model="selectId" data-placeholder="Select item by name" style="width:250px">
<option></option>
<option ng-repeat='item in items' data-show="{{item.show}}" value="{{item.id}}">
{{item.name}}
</option>
</select>
And the js contains the following:
$scope.items (an array that has a id, a boolean show property and a name property)
and the select 2 options:
select2Options : {
allowClear: true,
placeholder:"select a value",
formatResult: function(state) {
var $elem = angular.element(state.element),
isVisible = $elem.data('show');
return isVisible ? '<span style="color:red">'+state.text+'</span>':
<span style="color:blue">'+state.text+'</span>';
}
},
Well, the ng-repeat updates correctly the html markup and sets data-show attribute to either true or false, but the formatResult function does not update this value.
In the html source the data-show="true" and in the formatResult function $elem.data('show') = false;, why doesn't it update while the function is called every time the select2 is opened?
Here is made a plunker that illustrates my question: plnkr.co/edit/d0LxuhzdQh7hMdzOoxpr?p=preview .It looks the formatResult updates the results correctly only once before opening the select2 for the first time.
Edit
http://plnkr.co/edit/6Vma1WTQWQw0HAIQUVxE?p=preview
$scope.select2options = {
allowClear: true,
placeholder: "select a value",
formatResult: function(state, container) {
var $elem = angular.element(state.element);
var scope = $elem.data('$scope');
if (scope !== undefined) {
isVisible = scope.$eval($elem.data('show'));
$scope.dataShow[$elem.attr('value')] = isVisible;
$scope.updated++;
return isVisible ? '<span style="color:red">' + state.text + '</span>' :
' <span style="color:blue">' + state.text + '</span>'
}
}
}
The key part is grabbing the $scope data from the jqLite element and then calling $eval, which evaluates an unparsed string expression in the context of the scope. If we had used $scope.$eval, it would have used the controller $scope, which wouldn't have the ng-repeat on it. By grabbing it from the element we have a scope that has access to the item property for the ng-repeat.
Having said that I don't recommend using this code (sometimes jQuery widgets force you into unpleasant corners when working with angular). Again if you find yourself manipulating angular.element or using $element in a controller you probably should use a directive instead. Then again we programmers have to deal with non-ideal constraints (time, money, etc.) that prevent us from working "ideally" so given your context this may be a decent solution.
Let me know if any of my explanation doesn't make sense.

Is this what you want?
JavaScript
$scope.items = [{
id: 1,
show: false,
name: 'test1'
}, {
id: 2,
show: true,
name: 'test2'
}, {
id: 3,
show: true,
name: 'test3'
}];
$scope.selections = [1, 2];
$scope.getStyleForIndex = function (index) {
var item;
for (var i = 0; i < $scope.items.length; i++) {
if (i === index) {
item = $scope.items[i];
break;
}
}
return item.show ? { color: "red" } : { color: "blue" };
}
$scope.select2options = {
allowClear: true,
formatResult: function(item, container) {
var color = $scope.getStyleForIndex(parseInt(item.id, 10)).color;
container.html('<span style="color:' + color + '">RESULT ' + item.text + '</span>');
},
formatSelection: function(item, container) {
container.append($compile('<span ng-style="getStyleForIndex(' + item.id + ')">SELECTION ' + item.text + '</span>')($scope));
}
}
HTML
<div ng-repeat="item in items">
{{ item.name }}
<input type="checkbox" ng-model="item.show" />
</div>
<select ui-select2="select2options" ng-model="selections" style="width:200px" multiple="true" ng-options="i.id as i.name for i in items"></select>
{{selections}}
I have a AngularJS directive that allows users to select a values from a list to filter on. Pretty simple concept which is represented here:
Problem is when I click one of the checkboxes they all select unintended. My directive is pretty simple so I'm not sure why this is happening. The code around the selection and checkboxes is as follows:
$scope.tempFilter = {
id: ObjectId(),
fieldId: $scope.available[0].id,
filterType: 'contains'
};
$scope.toggleCheck = function (id) {
var values = $scope.tempFilter.value;
if (!values || !values.length) {
values = $scope.tempFilter.value = [];
}
var idx = values.indexOf(id);
if (idx === -1) {
values.push(id);
} else {
values.splice(idx, 1);
}
};
$scope.valuesListValues = function (id) {
return $scope.available.find(function (f) {
return f.id === id;
}).values;
};
and the data resembles:
$scope.available = [{
id: 23,
name: 'Store'
values: [
{ id: 124, name: "Kansas" },
{ id: 122, name: "Florida" }, ... ]
}, ... ]
the view logic is as follows:
<ul class="list-box">
<li ng-repeat="val in valuesListValues(tempFilter.fieldId)">
<div class="checkbox">
<label ng-click="toggleCheck(val.id)">
<input ng-checked="tempFilter.value.indexOf(val.id) === -1"
type="checkbox"> {{val.name}}
</label>
</div>
</li>
</ul>
First off, it toggleCheck fires twice but populates the correct data ( second time given my code it removes it though ).
After the second fire, it checks all boxes... Any ideas?
Perhaps its that the local variable doesn't get reassigned to the property of the scope property used in the view. Since your values are then non-existent and not found, the box is checked.
$scope.tempFilter.value = values
I took the interface concept you were after and created a simpler solution. It uses a checked property, found in each item of available[0].values, as the checkbox model. At the top of the list is a button that clears the selected items.
JavaScript:
function DataMock($scope) {
$scope.available = [{
id: 23,
name: 'Store',
values: [{
id: 124,
name: "Kansas"
}, {
id: 122,
name: "Florida"
}]
}];
$scope.clearSelection = function() {
var values = $scope.available[0].values;
for (var i = 0; i < values.length; i++) {
values[i].checked = false;
}
};
}
HTML:
<body ng-controller="DataMock">
<ul class="list-box">
<li>
<button ng-click="clearSelection()">Clear Selection</button>
</li>
<li ng-repeat="val in available[0].values">
<div class="checkbox">
<label>
<input ng-model="val.checked"
type="checkbox" /> {{val.name}}
</label>
</div>
</li>
</ul>
</body>
Demo on Plunker
The repeat that I used to grab the values based on the id, was the problem area.
<li ng-repeat="val in valuesListValues(tempFilter.fieldId)">
removing that and simple listening and setting a static variable resolved the problem.
$scope.$watch('tempFilter.fieldId', function () {
var fId = $scope.tempFilter.fieldId;
if ($scope.isFieldType(fId, 'valuesList')) {
$scope.valuesListValues = $scope.valuesListValues(fId);
}
}, true);
});
and then in the view:
ng-repeat="value in valuesListValues"
