使用jquery动态加载js文件的方法教程

方法很简单，这里就不多废话了，直接奉上代码：

代码如下:

$.extend({
     includepath: '',
     include: function(file) {
        var files = typeof file == "string" ? [file]:file;
        for (var i = 0; i < files.length; i++) {
            var name = files[i].replace(/^\s|\s$/g, "");
            var att = name.split('.');
            var ext = att[att.length - 1].tolowercase();
            var iscss = ext == "css";
            var tag = iscss ? "link" : "script";
            var attr = iscss ? " type='text/css' rel='stylesheet' " : " language='javascript' type='text/javascript' ";
            var link = (iscss ? "href" : "src") + "='" + $.includepath + name + "'";
            if ($(tag + "[" + link + "]").length == 0) $("body").append("<" + tag + attr + link + "></" + tag + ">");
        }
   }
});

//使用方法
$.includepath = '../js/exam';
$.include(['/addquestion.js']);
