jQ +prepent如何在body前边加<script>?

Question

var url = window.location.href;
var topicUrl='http://www.rodo.cc/topics/19266.html';
if(url == topicUrl){
$("body").prepend("<script src='http://club.hukiio.com/source/plugin/kccdeeofficalwebsite/js/crossTopWindow.js'></script>");

    }

这里加载错误，请问怎么调整？谢谢

Answer 1

实在不行使用$.getScript()方法吧

$.getScript("test.js", function(){
  alert("Script loaded and executed.");
});

Answer 2

js 异步加载原生方式

var myScript= document.createElement("script");
myScript.type = "text/javascript";
myScript.src="my.js";
document.body.appendChild(myScript);

jquery的方式

$.getScript("test.js", function(){
  callbackFunc;
});
