如何动态的导入js文件具体该怎么实现_javascript技巧

var docFunc = {

/***************************************************************************
* purpose: 调用下面的动态加载脚本方法load_script
**************************************************************************/

loaddefJquery : function() {
//alert(ucapSession.hostPath + ucapSession.appPath);

//ucapSession.appPath为根目录
docFunc.load_script(ucapSession.appPath
+ "ftdxxglxt/js/jquery-1.8.1.min.js");
docFunc.load_script(ucapSession.appPath
+ "ftdxxglxt/js/jSuggest.js");
},

/***************************************************************************
* purpose: 动态加载脚本
**************************************************************************/
load_script:function(url){
var x = new ActiveXObject("Msxml2.XMLHTTP");
x.open('GET', url, false);
x.send('');
eval(x.responseText);
var s = x.responseText.split(/\n/);
var r = /^(?:function|var)\s*([a-zA-Z_]+)/i;
for (var i = 0; i {
var m = r.exec(s[i]);
if (m != null)
{
window[m[1]] = eval(m[1]);
}
}
}

}

<script> <BR>docFunc.loaddefJquery(); <BR></script>
