javascript - "SRC' ed”时是否可以访问脚本标签内容？

Question

我做了一个简单的test(jsbin)与:

 <script id='a' type="text/javascript">
   {a:1} //dummy value
   var a=1;
 </script>

然后:

alert($("#a").text());

结果是:

但是 - 使用 src 时有什么方法可以访问内容吗？ 使用脚本标签？

示例:

<script id='a' src="myjs.js" type="text/javascript"></script>

这似乎不起作用

换句话说:

if you have <script src="src">contents</script> - how to get "contents"

来自MDN ,

脚本标签

This attribute specifies the URI of an external script; this can be used as an alternative to embedding a script directly within a document. script elements with an src attribute specified should not have a script embedded within its tags.
