I am building radio buttons dynamically. ng-change='newValue(value)
stops being called after each radio button has been pressed once.
this works: Clicking on the radio buttons changes the value to foo/bar/baz. http://jsfiddle.net/ZPcSe/19/
<div ng-controller="MyCtrl">
<input type="radio" ng-model="value" value="foo" ng-change='newValue(value)'>
<input type="radio" ng-model="value" value="bar" ng-change='newValue(value)'>
<input type="radio" ng-model="value" value="baz" ng-change='newValue(value)'>
<hr>
{{value}}
</div>
this code does not: The {{value}} - "label" is not updated once each radio button has been pressed at least once. Aparently ng-change is not fired any more.
<div ng-controller="MyCtrl">
<span ng-repeat="i in [0, 1, 2]">
<input name="asdf" type="radio" ng-model="value" value={{i}} ng-change='newValue(value)'>
</span>
{{value}}
</div>

The Controlles is the same each time:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.value = '-';
$scope.newValue = function(value) {
$scope.value = value;
}
}
Thanks for your help.
ngRepeat
creates new scope, so trying to set value
sets it on the new scope. The workaround is to reference a property on an object that is on the parent scope--the object lookup happens on the parent scope, and then changing the property works as expected:
HTML:
<div ng-controller="MyCtrl">
<span ng-repeat="i in [0, 1, 2]">
<input name="asdf" ng-model="options.value" value="{{i}}" type="radio">
</span>
{{options.value}}
JS:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.options = {
value: '-'
};
$scope.newValue = function(value) {
// $scope.options.value = value; // not needed, unless you want to do more work on a change
}
}
You can check out a working fiddle of this workaround. See angular/angular.js#1100 on GitHub for more information.
