在飞行中从外部站点加载js [英] Load js from external site on fly

问题描述

我想在用户点击按钮时从外部网站加载JS代码。例如：

I want to load JS code from external site when user click on button. For example:

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

当用户按下按钮时，我们会在文档中添加新脚本：

and when user press button we attach new script to the document:

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

然后我们必须执行此脚本。这是真的吗？

and then we must execute this script. Is it real?

推荐答案

检查一下：如何动态加载来自不同域的javascript文件？

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
    }
};
