從外部網站上運行加載js

Question

我想在用戶點擊按鈕時從外部網站加載JS代碼。例如：

<button onclick="LoadJSFromURL('facebook.com/blablabla')" /> 

，當用戶按下按鈕，我們重視新的腳本文件：

<script> Share.WorkUrl="http://MySite.com"; Share.UserId=5 </script> <script src="http://Facebookcom/blabalbal" ></script> 

，然後我們必須執行這個腳本。這是真的嗎？

檢查：How do you dynamically load a javascript file from different domain?

var script = new Element("script", {src: "myBigCodeLibrary.js", type: "text/javascript"}); 

script.onload = script.onreadystatechange = function(){ 
    if (!this.readyState || 
     this.readyState == "loaded" || this.readyState == "complete") { 
     //script is loaded 
    } 
};
