Passing multiple argument to ng-click method
提问by Jaison Justus
In my code i like to pass to arguments to the function specified inside the ng-click attribute.
在我的代码中，我喜欢将参数传递给 ng-click 属性中指定的函数。
<div class="shout" ng-repeat="user in users">
<p>{{user.name}}</p>
<img src="media/images/delete.png" ng-click="deleteUser({{$index}},{{user._id}})"/>
</div>
and in the controller
并在控制器中
function deleteUser(index, userId){...}
the parameter index is to remove the user from $scope.user and user._id to remove it from the mongodb. i am a newbee to angular js.
参数index是从$scope.user和user._id中移除用户，将其从mongodb中移除。我是 angular js 的新手。
when i tried like this the deleteUser is not getting called. if i pass single argument it works like charm but when i pass more than its not working
当我这样尝试时，没有调用 deleteUser。如果我传递单个参数，它就像魅力一样，但是当我传递的不仅仅是它不起作用时

You don't need {{ }}while specifying arguments to an event handlers (ng-click). The correct syntax would be ng-click="deleteUser($index, user._id):
{{ }}在为事件处理程序 ( ng-click)指定参数时不需要。正确的语法是ng-click="deleteUser($index, user._id)：
<div class="shout" ng-repeat="user in users">
<p>{{user.name}}</p>
<img src="media/images/delete.png" ng-click="deleteUser($index, user._id)"/>
</div>
Here is a working plunker based on the code you've provided (check the console to see that click handler is working correctly): http://plnkr.co/edit/26A4Rj0FScPXYU7z92E6?p=preview
这是一个基于您提供的代码的工作 plunker（检查控制台以查看点击处理程序是否正常工作）：http://plnkr.co/edit/26A4Rj0FScPXYU7z92E6?p=preview
