如何从另一个脚本调用函数(AngularJS)

问题描述

这是我的问题的简化版本.假设我有 loadMe.js 脚本，其中包含返回一些数组的简单函数.

Here is the simplified version of my problem.Let's say that I have loadMe.js script containing simple function which is returning some array.

CallMe = function(){
return [1,2,3];
}

是否有可能在 ng 中创建另一个脚本来加载 loadMe.js 脚本，而不是从 调用 CallMe 函数loadMe.js 脚本并返回该函数返回的任何内容，在本例中为数组 [1,2,3].谢谢！

Is there any possibility in ng to create another script which will load loadMe.js script , than invoke CallMe function from loadMe.js script and return whatever that function is returning, in this case array [1,2,3].Thank You!

推荐答案

将 loadMe.js 变成一个模块，如:

Make loadMe.js into a module like:

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

loadMe.factory('loadMe', [function(){

return {
    'callMe':function(){
        return[1,2,3];
    }
}]);

然后将模块注入您的应用程序:

Then inject the module into your app:

var myApp = angular.module('myApp', ['loadMe']);

然后在您的控制器中使用它:

Then use it in your controller:

myApp.controller('mainController', ['$scope', 'loadMe', function ($scope, loadMe) {
//use loadMe to get [1,2,3]
var array = loadMe.callMe();
 console.log(array); //will log [1,2,3]

});

不要忘记在 HTML 中包含该模块

Don't forget to include the module in your HTML

<script src="/assets/js/models/loadMe.js"></script>

如果您想直接从您的视图中获取数组，您可以将您的 loadMe 模块添加到控制器的作用域中:

---

If you are looking to get the array directly from your view you can add your loadMe module to the controller's scope:

$scope.loadMe = loadMe;

然后在您的视图中您可以使用 {{loadMe.callMe()}}

Then in your view you can use {{loadMe.callMe()}}
