如何在“ ng-click”事件中动态调用angularjs函数？

Question

I want to call a function dynamically as the function name string will come from database. 我想动态调用一个函数，因为函数名称字符串将来自数据库。 ie "myNameIsGopal". 即“ myNameIsGopal”。

Using window"myNameIsGopal", I am able to call a function which is not there in the controller, but I want to call a function inside angular controller dynamically. 使用窗口“ myNameIsGopal”，我可以调用控制器中不存在的函数，但是我想动态地调用角度控制器中的函数。

Right now, I have defined following function outside the controller, which I am able to call using window"myNameIsGopal" 现在，我已经在控制器外部定义了以下函数，我可以使用窗口“ myNameIsGopal”调用该函数

function myNameIsGopal(args){
alert(args);}

But I want to call a method like this from inside of the controller. 但是我想从控制器内部调用这样的方法。

$scope.myNameIsGopal=function(args){
alert(args);
};

Below is My html page: 以下是我的html页面：

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link rel="stylesheet" href="style.css" />
    <script data-require="angular.js@1.3.x" src="https://code.angularjs.org/1.3.16/angular.js" data-semver="1.3.16"></script>
    <script src="app.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <p>Hello {{name}}!</p>

    <input type="text" ng-model="value" ng-enter="hideToolTip(event)" />

    <input type="button" ng-model="gobar" ng-click="dynamicCaller('myNameIsGopal','banana')" value="click me">`enter code here`
  </body>

</html>

Below is App.js code: 以下是App.js代码：

var app = angular.module('plunker', []);

function myNameIsGopal(arg){
    alert(arg);
  }
app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';


 $scope.dynamicCaller=function(arg1,arg2){
   window[arg1](arg2);
  }

  $scope.myNameIsGopal=function(arg){
    alert(arg);
  }



  $scope.hideToolTip = function(event) {
    alert(event);
  }
});

You were close, as function are defined in $scope object use it not window 您已关闭，因为函数是在$scope对象中定义的，请使用它而不是window

$scope.dynamicCaller=function(arg1,arg2){
   $scope[arg1](arg2);
}

 var app = angular.module('plunker', []); app.controller('MainCtrl', function($scope) { $scope.name = 'World'; $scope.dynamicCaller = function(arg1, arg2) { $scope[arg1](arg2); } $scope.myNameIsGopal = function(arg) { console.log(arg); } $scope.hideToolTip = function(event) { console.log(event); } });

 <script src="https://code.angularjs.org/1.3.16/angular.js"></script> <div ng-app="plunker" ng-controller="MainCtrl"> <p>Hello {{name}}!</p> <input type="button" ng-click="dynamicCaller('hideToolTip', 'mango')" value="click hideToolTip"/> <input type="button" ng-click="dynamicCaller('myNameIsGopal','banana')" value="click myNameIsGopal"> </div>
