I am generating a bunch of radio buttons using ng-repeat, and then trying to update a model when one of them is selected. This doesn't appear to be working.
The same markup works just fine when the radio inputs are hardcoded as opposed to being generated by ng-repeat.
This works:
<input type="radio" ng-model="lunch" value="chicken" name="lunch">
<input type="radio" ng-model="lunch" value="beef" name="lunch">
<input type="radio" ng-model="lunch" value="fish" name="lunch">
{{lunch}}
This doesn't:
<input type="radio" ng-model="lunch" ng-repeat="m in meat" value="m" name="lunch">
{{lunch}}
See jsfiddle showing both here: http://jsfiddle.net/mark_up/A2qCS/1/
Any help would be appreciated.
Thanks
<div ng-controller="DynamicCtrl">
<input type="radio" ng-model="$parent.lunch" ng-repeat="m in meat"
ng-value="m" name="lunch">
{{lunch}}
</div>
Should do the trick.
As I understand it, ng-repeat
creates its own $scope
. so you need to refer to the $parent $scope;
Yes, AngularJS is tricky. Also you need to change the value
to ng-value
too.
the above issue was discussed here
That happens because ng-repeat creates a new scope. Basically, each <input>
is creating a selectedOption value on its own inner scope. To work around that, create a new container object for that value. For example, you could declare in your controller:
$scope.data = {selectedOption: x};
And then in your template, use ng-model="data.selectedOption"
in this way, ng-model gets updated .. :)
this is tricky
Just need to replace value with ng-value
