I want to add to the following:
<input type="radio" ng-name='{{quest.id}}' ng-model='$parent.$parent.choice.input' ng-value='{{option}}' id='{{quest.id}}-{{option.id}}' ng-required='required'>
An attribute: ng-checked='checklast'
only if some condition is true,how do i do that?
just an example
<input type="radio" ng-checked="testModel.child_1 && testModel.child_2" ng-model="isChecked"/>
EDIT
if you using ng-repeat for displaying the list of radio then
<input type="radio" ng-name='{{quest.id}}' ng-model='$parent.$parent.choice.input' ng-value='{{option}}' id='{{quest.id}}-{{option.id}}' ng-required='required' ng-checked="$index == $last">

I have something like this:{{item.bla|| item.bla2}}
how can i put this in ng-model, i can't just do it like this:
input class="form-control" type="text" ng-model="{{item.bla || item.bla2}}"
Maybe this will help (assuming item is in scope):
<input class="form-control" type="text" ng-init="model= item.bla || item.bla2"
ng-model="model" />
In my HTML page, I have two sets of Boolean based radio buttons: Labeled: "Yes" and "No" / Values: True and False respectively. I'm populating a full form from a PostgreSQL database table to allow the authenticated user to view the form with populated data and edit the populated fields including the radio buttons, then save the form which will save the data to the DB. All of the other text fields populate without issue; it's both collection of radio buttons I am having an issue with pre-checkmarking the radio buttons.
The below does not pre-populate the checked on front end (but adds the correct attribute of checked in HTML source):
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" value="FALSE" ng-checked="person.billing == 'false'" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" value="TRUE" ng-checked="person.billing == 'true'" />
However, this does check the correct radio button on load:
<input id="billing-no" type="radio" name="billing" value="FALSE" ng-checked="person.billing == 'false'" />
<input id="billing-yes" type="radio" name="billing" value="TRUE" ng-checked="person.billing == 'true'" />
Note: I needed to check against the string boolean value in the directive ng-checked since the boolean value always comes back as a string from PostgreSQL. This, apparently, was a part of PostgreSQL's design when querying data from columns that have boolean data types.
When adding the ng-model directive, the radio button no longer is checked (at least in the rendered browser view). The odd part is that I looked at the source and it clearly checks the correct one. What's even more odd, is that I have to click on the radio button twice to 'check' it. I've tested this in latest version of Chrome, FF, and IE and it all results in the same issue.
The question is: when adding the ng-model directive, why would the HTML source add 'checked' in the radio button attribute, but seemingly does not mark the radio button? Furthermore, why would I have to click twice on the radio button that IS supposed to be checked?
Solution:
To fix this, I removed the ng-checked directive from the radio buttons and only used ng-model as suggested by #Cypher and #aet. I then replaced the attribute value with the directive ng-value "true" & "false". After, I set the values in the controller.
HTML
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="false" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="true" />
Angular JS
app.controller('peopleCtrl', function($scope, peopleFactory){
...
peopleFactory.getPerson(personParams).then(function(data){
$scope.person = data;
/* moved from ng-checked */
$scope.person.billing = data.billing == 'true';
});
...
};
I think you should only use ng-model and should work well for you, here is the link to the official documentation of angular https://docs.angularjs.org/api/ng/input/input%5Bradio%5D
The code from the example should not be difficult to adapt to your specific situation:
<script>
function Ctrl($scope) {
$scope.color = 'blue';
$scope.specialValue = {
"id": "12345",
"value": "green"
};
}
</script>
<form name="myForm" ng-controller="Ctrl">
<input type="radio" ng-model="color" value="red"> Red <br/>
<input type="radio" ng-model="color" ng-value="specialValue"> Green <br/>
<input type="radio" ng-model="color" value="blue"> Blue <br/>
<tt>color = {{color | json}}</tt><br/>
</form>
I solved my problem simply using ng-init for default selection instead of ng-checked
<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />

Avoiding using $scope, based on John Papa Angular Style Guide
so my idea is take advantage of the current model:
(function(){
'use strict';
var app = angular.module('way', [])
app.controller('Decision', Decision);
Decision.$inject = [];
function Decision(){
var vm = this;
vm.checkItOut = _register;
function _register(newOption){
console.log('should I stay or should I go');
console.log(newOption);
}
}
})();
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div ng-app="way">
<div ng-controller="Decision as vm">
<form name="myCheckboxTest" ng-submit="vm.checkItOut(decision)">
<label class="radio-inline">
<input type="radio" name="option" ng-model="decision.myWay"
ng-value="false" ng-checked="!decision.myWay"> Should I stay?
</label>
<label class="radio-inline">
<input type="radio" name="option" ng-value="true"
ng-model="decision.myWay" > Should I go?
</label>
</form>
</div>
</div>
I hope I could help ;)
Please explain why same ng-model is used? And what value is passed through ng- model and how it is passed? To be more specific, if I use console.log(color) what would be the output?
can we change URL when radio button selected. I am using angularjs?
following is my code and I want to change url when input radiobox is selected
<div class="switch">
<input type="radio" class="switch-input" name="view" value="week" id="week" checked>
<label for="week" class="switch-label switch-label-off">
Automatically
</label>
<input type="radio" class="switch-input" name="view" value="month" id="month">
<label for="month" class="switch-label switch-label-on">
Manually
</label>
<span class="switch-selection">
</span>
</div>
In AngularJS, you can use the $location service to change path as:
$location.path('/new-route');
On your input tag, you can then use the ng-change or the ng-click directives to call a function that will change the route. So, it can be something like this:
<input type="radio" ng-click="changeLocation('route-name')>
With your controller having the following code:
$scope.changeLocation = function (newRoute) {
$location.path(newRoute);
};
In AngularJS, I'm trying to add/remove a checked class on a parent element, when its child radio button is checked/unchecked.
<label ng-class="{checked: menuType.isChecked0}">
<input type="radio" name="menuType" ng-model="menuType.isChecked0" />Text 1
</label>
<label ng-class="{checked: menuType.isChecked1}">
<input type="radio" name="menuType" ng-model="menuType.isChecked1" />Text 2
</label>
Here is a fiddle: http://jsfiddle.net/fAA2w/
There is no controller or any other relative code. If there is a better way to approach this, please share. This seems simple enough, but I cannot find an answer to this question. What am I doing wrong here?
You need to give the radio input a value.
For more examples see http://docs.angularjs.org/api/ng/input/input%5Bradio%5D.
<div ng-app>
<label ng-class="{checked: isChecked == 1}">
<input type="radio" name="menuType" ng-model="isChecked" value="1" />Text 1
</label>
<label ng-class="{checked: isChecked == 2}">
<input type="radio" name="menuType" ng-model="isChecked" value= "2" />Text
</label>
</div>
This is the correct way to be doing it. Reason being, when your ng-model changes, your ng-class will pick up on that and update the view, the Angular way!
I'm using ng-repeat to generate a bunch of radiobuttons.
<div class="radiobutton" ng-repeat="mylabel in field.labels">
<input
type="radio"
name="{{field['key']}}"
value="{{mylabel.label}}"
id="{{mylabel.name}}"
>
<label for="{{field['key']}}">
{{mylabel.label}}
</label>
</div>
I would like to add a class to the input-element based on if the input-element is checked or not, using angluar. As far as I can understand I should apply a ng-model to the element and then use that to declare a ng-class, but how do I make it so that each input get's it's own model-name?
try:
<div class="radiobutton" ng-repeat="mylabel in field.labels">
<input
type="radio"
name="{{field['key']}}"
value="{{mylabel.label}}"
id="{{mylabel.name}}"
ng-model='$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.
