如何使用AngularJs捕获按钮单击事件并显示警告框

Question

How can we trigger the button click event using AngularJs and show an alert message box? I have tried the alert("message") messagebox but it doesn't work.

Answer 1

You can use ng-click on button something like this:

Controller :

   var VLogin = angular.module('myApp',[]);
   VLogin.controller('TestCtrl', ['$scope',function($scope) {

   $scope.clicked = function(){
        alert("Clicked");
    }
}]);

And in your HTML like :

<div ng-app="myApp">
    <div ng-controller="TestCtrl">
      <button ng-click="clicked()">Click me!</button>
    </div>
</div>

Here is the working Fiddle :- http://jsfiddle.net/nuejh9h6/
