如何使用自定义角度指令加载脚本？ [英] How to load a script using custom angular directive?

问题描述

我正在尝试在自定义角度指令中加载脚本。现在，它只是在DOM中添加脚本标记，但它没有加载它。

I am trying to load a script in my custom angular directive. Right now, it is simply adding script tag in DOM but it is not loading it.

angular.module('myApp')
  .directive('rjHeader', function () {
    return {
      restrict: 'E',
       template : function(e,a){
           return '<script type="text/javascript" charset="utf-8" src="https://my.web.com/path/' + a.locale + '/some.js" ></script>';  
        }
    };
  });

---

并且在html中

---

And in html

<div rj-Header locale="en_US"></div>

---

在浏览器中打开页面时，它正确添加预期的脚本。

---

When opening the page in browser, it correctly adds the intended script.

<script type="text/javascript" charset="utf-8" src="https://my.web.com/path/en_US/some.js" ></script> 

但实际上并没有加载这个.js文件。如果我简单地将此行粘贴到我的html，那么它按预期工作。如何使用自定义角度指令注入脚本？

But this doesn't actually loads this .js file. If I simple copy paste this line to my html then it works as expected. How can I inject script using custom angular directive?

推荐答案

这里似乎有点不对，但如果你真的想这样做你可以在你的指令元素上附加一个脚本标记：

Something seems a little wrong here, but if you really wanted to do this you could just append a script tag to your directive's element:

app.directive('loadDirective', function() {
  return {
    restrict: 'E',
    link: function($scope, $el) {

      var script = document.createElement('script');
      script.src = '//cdnjs.cloudflare.com/ajax/libs/emojione/1.3.0/lib/js/emojione.min.js'
      $el.append(script);
    }
  }
});
