I'm using ng-repeat to generate a bunch of radiobuttons.
<div class="radiobutton" ng-repeat="mylabel in field.labels">
<input
type="radio"
name="{{field['key']}}"
value="{{mylabel.label}}"
id="{{mylabel.name}}"
>
<label for="{{field['key']}}">
{{mylabel.label}}
</label>
</div>
I would like to add a class to the input-element based on if the input-element is checked or not, using angluar. As far as I can understand I should apply a ng-model to the element and then use that to declare a ng-class, but how do I make it so that each input get's it's own model-name?
try:
<div class="radiobutton" ng-repeat="mylabel in field.labels">
<input
type="radio"
name="{{field['key']}}"
value="{{mylabel.label}}"
id="{{mylabel.name}}"
ng-model='$parent.my_radio_button'
ng-class='{ class_name: (my_radio_button == mylabel.label) }'
>
<label for="{{field['key']}}">
{{mylabel.label}}
</label>
</div>
Since you use radio buttons, I guess only one can be selected, so you can share the same ng model.

In my angular app I'm using ng-repeat to generate several radio buttons, the ultimate goal is to add a choiceSelected class (ngClass colour styling) to the label of the clicked radio input. I can add the style to the clicked button, BUT that style is added to every other clicked radio button and I end up with 5 coloured labels. Can't understand why.
Here is the HTML code:
<div class="row" ng-repeat="obj in questionObject.choices">
<div class="radio">
<label class="choice" ng-class="{'choiceSelected': isChecked==$index}">
<input type="radio" name="optradio" ng-model="isChecked" ng-value="$index" ng-click="selectAnswer($index,questionObject)">{{obj.body}}</label>
</div>
</div>
<div class="row" ng-repeat="obj in questionObject.choices">
<div class="radio">
<label class="choice" ng-class="{'choiceSelected': isChecked==$index}">
<input type="radio"
name="optradio"
/*********************************************/
ng-model="isChecked"
ng-value="$index"
/*********************************************/
ng-click="selectAnswer($index,questionObject)">{{obj.body}}
</label>
</div>
</div>
Look at the lines inside the comments, clearly tells that your value of the checkbox($index) is binding to the isChecked variable.
By your, condition in ng-class isChecked==$index it is same for all the elements and so the class is applied for all radio buttons.
if you can update the Json of questionObject , can give you alternative option.
Assuming that questionObject contains the following json
[{
"body": "abc"
}, {
"body": "def"
}, {
"body": "aghi"
} ]
You can use the below code to make your result achieve
<div class="row" ng-repeat="obj in questionObject track by $index" >
<div class="radio" >
<label class="choice"
ng-class="{'choiceSelected': isChecked==$index}">
<input type="radio"
name="optradio"
ng-value="obj.body"
ng-click="selectAnswer($index,obj)">
{{obj.body}}
</label>
</div>
The method selectAnswer should make your work simple. Use this
$scope.selectAnswer=function(number,obj)
{
$scope.isChecked=number;
}

NOTE: In your code the selectAnswer method call in HTML passes the
questionObject fully

Reason for manually defining isChecked
Angular looks for the the value of isChecked in the scope because you have used ng-class in the
I have validation issue if i use k-ng-model on field that field is not required with Angularjs validation , User can submit the form so below code field is required even i dont select the value user can still submit the form.. Any idea how to solve it ?
main.html
<div class="row">
<div class="form-group col-md-12">
<label for="themesList" class="required col-md-4">Themes:</label>
<div class="col-md-8">
<select class="multiselect" kendo-multi-select="themes"
k-options="challengThemesOptions" data-text-field="'text'"
data-value-field="'id'" name="themesList"
k-ng-model="challengesDTO.themesKyList" required
id="themesList"></select>
<p class="text-danger" ng-show="addChallengeForm.themesList.$touched && ddChallengeForm.themesList.$error.required">Theme(s) is required</p>
</div>
</div>
</div>
You can use ng-model with k-ng-model, Try assigning ng-model to a seperate variable and use ng-required.
<select class="multiselect" kendo-multi-select="themes"
k-options="challengThemesOptions" data-text-field="'text'"
data-value-field="'id'" name="themesList"
k-ng-model="challengesDTO.themesKyList" ng-model="challengesDTO.themesKyListValue" ng-required
id="themesList"></select>
This solution worked for me: kendo ui, angular require validation for numeric text box
Just create a hidden input for the each kendo widget and bind the model from your k-ng-model also to the ng-model of the hidden field. The k-ng-model seems to be no NgModelController, which is why the validators cannot hook into the models $validators and do their work.
<input kendo-date-time-picker k-ng-model="$ctrl.event.endDate"></input>
<input type="hidden" name="endDate" ng-model="$ctrl.event.endDate" required></input>
I have one checkbox list. I need to disable all elements which have model value set to false initially. But because of two way binding I have a problem when I deselect one checkbox it becomes disabled. How to solve it?
<div class="item-s" ng-repeat="element in model.elements">
<input id="element{{$index.toString()}}"
type="checkbox"
ng-true-value="true"
ng-false-value="false"
ng-model="element.value"
ng-disabled="!element.value" />
<label for="element{{$index.toString()}}">{{element.name}}</label>
</div>
Adding :: in front of a binding expression causes it to only be evaluated once. This should get you what you need:
ng-disabled="::!element.value"
Here's Angular's docs on one-time binding.
Try using ng-init:
<div id="myApp" ng-controller="MyController">
<div class="item-s" ng-repeat="element in model.elements">
<input id="element{{$index.toString()}}" type="checkbox" ng-true-value="true" ng-false-value="false" ng-model="element.value" ng-init="initValue = element.value" ng-disabled="initValue==false" />
<label for="element{{$index.toString()}}">{{element.name}}</label>
</div>
</div>
Here is JSFiddle: http://jsfiddle.net/jz65o9tv/
I created this simple example: http://jsfiddle.net/5Bh59/.
If you switch between AngularJS 1.2.1 and 1.1.1, you'll see the radio buttons don't work properly in either version. If you watch the radio button's $dirty field, 1) for version 1.1.1, it will only be set when the first button is clicked, and 2) for version 1.2.1, it will only be set when the last button is clicked.
I read this answer: AngularJS Radio group not setting $dirty on field but I don't really understand the answer. Not only that but the fiddler example demonstrates the same behavior.
So, is this a bug in AngularJS and how can I work around it?
You either need to give each radio button input a different name, or you need to wrap each radio button in an ng-form (each of which have a different name). If you use two inputs with the same name in the same form, only the last one will be bound to the property on the FormController. If you use different names, then each input will have its own property on the FormController.
Example with different names for each radio button:
http://jsfiddle.net/BEU3V/
<form name="form" novalidate>
<input type="radio"
name="myRadio1"
ng-model="myRadio"
ng-click=""
value="Rejected"
required>Rejected<br />
<input type="radio"
name="myRadio2"
ng-model="myRadio"
ng-click=""
value="Approved"
required>Approved<br />
Form $dirty: {{form.$dirty}}<br />
Field1 $dirty: {{form.myRadio1.$dirty}}<br />
Field1 $dirty: {{form.myRadio2.$dirty}}<br />
Value: {{myRadio}}
</form>
Example wrapping with ng-form:
http://jsfiddle.net/39Rrm/1/
<form name="form" novalidate>
<ng-form name="form1">
<input type="radio"
name="myRadio"
ng-model="myRadio"
ng-click=""
value="Rejected"
required>Rejected<br />
</ng-form>
<ng-form name="form2">
<input type="radio"
name="myRadio"
ng-model="myRadio"
ng-click=""
value="Approved"
required>Approved<br />
</ng-form>
Form $dirty: {{form.$dirty}}<br />
Field1 $dirty: {{form.form1.myRadio.$dirty}}<br />
Field2 $dirty: {{form.form2.myRadio.$dirty}}<br />
Value: {{myRadio}}
</form>
If you'd like a single check for the radio group, you can wrap all the radio buttons in their own ng-form and call it something like name="radioGroup".
http://jsfiddle.net/6VVBL/
<form name="form" novalidate>
<ng-form name="radioGroup">
<input type="radio"
name="myRadio1"
ng-model="myRadio"
ng-click=""
value="Rejected"
required>Rejected<br />
<input type="radio"
name="myRadio2"
ng-model="myRadio"
ng-click=""
value="Approved"
required>Approved<br />
</ng-form>
Form $dirty: {{form.$dirty}}<br />
Group $valid: {{form.radioGroup.$valid}}<br />
Group $dirty: {{form.radioGroup.$dirty}}<br />
Value: {{myRadio}}
</form>
This answer is related but perhaps not exactly applicable, but after finding and reading this item I felt it valuable to provide, and I don't have enough points to just comment on an answer (which I thought would have been a more appropriate way to respond).
My issue was that I wanted to show a required error (using ng-messages) but when you tabbed through / past the radio button group $touched didn't turn true unless you shift-tabbed back from the next UI element back to the last radio button of the group. (When my form renders the radio buttons are not set - I'm wanting the user to make a selection and not rely on the user accepting a default.)
Here's my code:
<div class="form-group" ng-class="{'has-error': pet.genderId.$invalid && pet.genderId.$touched}">
<label class="control-label">
What is your pet's gender?
<span ng-messages="pet.genderId.$error" ng-show="pet.genderId.$invalid && pet.genderId.$touched">
<span ng-message="required">(required)</span>
</span>
</label>
<div>
<label class="radio-inline"><input type="radio" ng-model="genderId" name="genderId" value="1" required ng-blur="pet.genderId.$setTouched();" />Male</label>
<label class="radio-inline"><input type="radio" ng-model="genderId" name="genderId" value="2" required ng-blur="pet.genderId.$setTouched();" />Female</label>
<label class="radio-inline"><input type="radio" ng-model="genderId" name="genderId" value="3" required ng-blur="pet.genderId.$setTouched();" />Not sure</label>
</div>
</div>
The 'magic' was adding the ng-blur attribute to set 'touched' myself even if only the first radio button was tabbed past.
You may be able to employ a similar tactic for $dirty by calling $setDirty() in the ng-changed attribute.
In AngularJS, I'm trying to add/remove a checked class on a parent element, when its child radio button is checked/unchecked.
<label ng-class="{checked: menuType.isChecked0}">
<input type="radio" name="menuType" ng-model="menuType.isChecked0" />Text 1
</label>
<label ng-class="{checked: menuType.isChecked1}">
<input type="radio" name="menuType" ng-model="menuType.isChecked1" />Text 2
</label>
Here is a fiddle: http://jsfiddle.net/fAA2w/
There is no controller or any other relative code. If there is a better way to approach this, please share. This seems simple enough, but I cannot find an answer to this question. What am I doing wrong here?
You need to give the radio input a value.
For more examples see http://docs.angularjs.org/api/ng/input/input%5Bradio%5D.
<div ng-app>
<label ng-class="{checked: isChecked == 1}">
<input type="radio" name="menuType" ng-model="isChecked" value="1" />Text 1
</label>
<label ng-class="{checked: isChecked == 2}">
<input type="radio" name="menuType" ng-model="isChecked" value= "2" />Text
</label>
</div>
This is the correct way to be doing it. Reason being, when your ng-model changes, your ng-class will pick up on that and update the view, the Angular way!
