I'm trying to get multiple values selected form a checkbox list generated using ng-repeat in anguler
<div ng-repeat="item in items">
<input type="checkbox" ng-model="model.ID" ng-true-value="'{{item.ID}}'" ng-false-value="''"/>{{item.Name}}
</div>
But what I want is to have different ng-models for different check boxes. How can I do that. Is there a way to do what ng-repeat does with out using ng-repeat
In Angular one checkbox is linked with one model, but in practice we usually want one model to store array of checked values from several checkboxes.
Checklist-model solves that task without additional code in controller. examples
use $index as key
<div ng-repeat="item in items">
<input type="checkbox" ng-model="model[$index].ID"/>{{item.Name}}
</div>
or use item unique id:
<div ng-repeat="item in items">
<input type="checkbox" ng-model="model[item.ID]"/>{{item.Name}}
</div>

Is there a way to avoid IDs while creating elements i.e. using ng-model it is easier to validate form fields and other stuff?
<div ng-repeat="x in TestData">
<input type="text" id="nameField-{{$index}}"/>
</div>
The above code will display the number of input boxes equal to the length of the TestData array where every text box will have a unique id "nameField-0", "nameField-1" and so on, using these IDs we can take the textbox values, validate the fields etc.
<div ng-repeat="x in TestData">
<input type="text" ng-model=""/> <!-- what shall be done here to have unique IDs -->
</div>
Although going with IDs is working fine for me but as far as I can understand If I use IDs then that will not be a pure angular way (or IDs cannot be replaced by mg-models), correct me If I am wrong.
You don't need to grab element with id/name/etc. You can use ng-model to bind your values and ng-pattern to validate them.
<div ng-repeat="x in testData">
<ng-form name="tForm">
<input type="text" name="tInput" ng-model="x.name" ng-pattern="/^[A-Z]*$/" />
<span ng-if="tForm.tInput.$error.pattern" style="color:red">Invalid!</span>
</ng-form>
</div>
See this jsbin.
In your controller add this,
$scope.nameField = [];
in ng-reapeat add this,
<div ng-repeat="x in TestData">
<input type="text" ng-model="nameField[$index]"/>
</div>
nameField will be an array with all your values.
<div ng-repeat="x in TestData" ng-init='this["nameField-"+x]'>
<input ng-model='this["nameField-"+x]'/>
</div>
You use ng-init to add new variables to the controller, "this" refer to your scope, and since the scope is an object, since this[bla] == this.bla tou are actually saying, add to my scope a variable name "nameField=" and you add the x value.
after you have created your variable, just use it in the same way in your ng-model.
If you want to show your variable's value in any div/span, just use it via ng-bind:
<div ng-bind='this["nameField-"+x]'></div>
I want to create a a 3 radio button groups each having its own unique model using one ng-repeat. How can I achieve this?
<div class="radio" data-ng-repeat="item in selItem.items" >
<label class="control-label">
<input type="radio"
data-ng-value={{item.vm}}
data-ng-model="????"
name="{{selItem.Title}}"/>{{item.dm}}
</label>
</div>
First and foremost, why would you do that? Radio buttons are for a unique selection among a group of options, so having the same model for all radio buttons is the way to go.
However, for setting unique ng-models for each item iteration inside ng-repeat, you have to use object bracket notation, using $index or a property of each iteration itself to name the property of the object model.
<div ng-repeat="item in items">
<input type="text" ng-model="myModel[item.name]" >
</div>

I have number of checkboxes created using the ng-repeat based on the dynamic data, I want to set the ng-true-value of a checkbox with the dynamic data, that is a string, My code is as Follow:
<div ng-app="myApp" ng-controller="PostList">
<ul>
<li ng-repeat="ff in totalFeatures">
<input type="checkbox" ng-model="checkBoxModel.search[$index]" ng-true-value="{{ff}}" ng-false-value="" name="{{ff}}"/>
<label>{{ff}}</label>
</li>
</ul>
</div>
You have to define checkBoxModel.search[$index] as ng-model.
ng-true-value / ng-false-value represents the values which are bound to the model on true or false.
If these values are no boolean you have to wrap them with single quote too.
eg. ng-true-value="'{{ff.checkedTrueValue}}'"
Try to utilize ng-repeat instance like this
<li ng-repeat="ff in totalFeatures">
<input type="checkbox" ng-model="ff.isChecked" ng-true-value="{{ff.checkedTrueValue}}" ng-false-value="{{ff.checkedFalseValue}}" />
<label>{{ff}}</label>
</li>
You can get/set value of isChecked,checkedTrueValue,checkedFalseValue in $scope.totalFeatures
I am using ng-repeat in angularjs to display several checkboxes.
<div class="checkbox" ng-repeat="subject in priceinformation.subjects">
<label>
<input type="checkbox" ng-model="priceinformation.subscriptioninfo.subject.name"> {{subject.name}}
</label>
</div>
The problem is all the checkboxes are using the same model, hence if I check one, all are checked. I want to do it in a way that the model can resolve to different values. e.g.
ng-model="priceinformation.subscriptioninfo.subject.{{subject.name}}"
{{subject.name}} should resolve to something like English, History etc, hence a different model for each checkbox.
But ng-model="priceinformation.subscriptioninfo.subject.{{subject.name}}" is giving an error.
Note: {{subject.name}} is resolving correctly used elsewhere, and 'priceinformation.subscriptioninfo.subject' is working correctly.
Use [] instead of .
ng-model="priceinformation.subscriptioninfo[subject.name]"
Plnkr Demo
Script
$scope.priceinformation ={};
$scope.priceinformation.subjects = [{"name":"English"},{"name":"History"},{"name":"Maths"}];
$scope.priceinformation.subscriptioninfo ={};
<div ng-repeat="item in checks">
<input type="checkbox" ng-model="item.checked">{{item.name}}
</div>

I have a list of text fields with a button below it. I can add text fields to that list dynamically with AngularJS.
The text field by default has an empty value. But I want to order the position of the list item as soon as I update the value of that text field. But when I do that the orderBy isn't triggered.
How can I make this happen?
Here's a quick demo: http://jsfiddle.net/fqnKt/214/
I just wanted to specifically note why the example was wrong (because I had the same issue even though I was using the orderBy directive).
DO NOT USE
track by $index
In your ng-repeat
I think that this is what you want:
<div ng-app="myApp">
<div ng-controller="MyCtrl">
<ul>
<li ng-repeat="item in items | orderBy:'name'">
<input type="text" ng-model="item.name" /> {{item.name}}
</li>
</ul>
<input ng-model="newItem" type="text"></input>
<button ng-click="add(newItem)">Add</button>
</div>
</div>
