方法很简单，这里就不多废话了，直接奉上代码：

复制代码 代码如下:
$.extend({
     includePath: '',
     include: function(file) {
        var files = typeof file == "string" "");
            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']);
