js封装，一个JS文件引用多个JS文件

(function() { //加载

  varobj =  {};

  /**

   * 动态加载脚本函数

   * @param url 要加载的脚本路径

   * @param callback  回调函数

   */

  obj.loadScript =function(url,callback){

    var doc = document;

    var script = doc.createElement("script");

    script.type = "text/javascript";

    if(script.readyState){ //IE

      script.onreadystatechange = function(){

        if(script.readyState=="load"||script.readyState=="complete"){

         script.onreadystatechange = null;

         callback();

        }

      };

    }else{

      script.onload = function(){

        callback();

      };

    }

    script.src = url;

    doc.getElementsByTagName("head")[0].appendChild(script);

  };

 varjsList = [

   "js1.js",

   "js2.js"

 ];

  function callback(){

      jsList.length?obj.loadScript(jsList.shift(),callback)

        :(function(){time =null})();

  }

  var time = setTimeout(function(){obj.loadScript(jsList.shift(),callback)},25);

})();

 

只需要更改jsList就可以了
