AngularJS ng-click not invoked with {{$index}} used

问题

For some reason AngularJS does not fire off the event when {{$index}} is used in ng-click.

My html:

<div ng-controller="Ctrl">
  <ul>
    <li ng-repeat="foo in foos">
     <label>{{foo.name}}</label>
     <a href="#" ng-click="remove({{$index}})">X (doesnt work)</a>
     <a href="#" ng-click="remove(0)">Remove first element (works)</a>
    </li>
  </ul>
 </div>

Anyone knows how to fix this? Thanks

回答1:

The value of the ng-click attribute is evaluated as an angular expression, so simply use remove($index).

solved!

<div ng-repeat="idiomax in textos.idiomas ">
    <div class="idioma"  ng-click="cambiaridioma($index)" ng-class="idioma != $index || 'idioma-activo'" > 
    {{idiomax.idioma}}
    </div>
</div>

---

$scope.cambiaridioma = function (indice) {
        $scope.idioma = indice;

    }

I had to use $index in a string expression and this is how it worked:

HTML

<button ng-click="showUserStories($event, '#modal-id-prefix-' + $index)">Show Modal</button>

Script

$scope.showUserStories = function(event, modalId) {
        $(modalId).modal("show");
        event.stopPropagation();
    }
