JavaScript代码：
//为String对象增加方法isNullOrEmpty String.isNullOrEmpty = function (a) { if (a != null && a != "" && a != "undefined") return false; return true; } //为window/function增加方法usingNamespace window.usingNamespace = Function.usingNamespace = function (a) { var ro = window; if (String.isNullOrEmpty(a)) { return ro; }; var co = ro; var nsp = a.split("."); for (var i = 0; i < nsp.length; i++) { var cp = nsp[i]; if (!ro[cp]) { ro[cp] = {}; }; co = ro = ro[cp]; }; return co; }; //创建命名空间"sss.bbb" //创建类aaa //创建类成员 msg,name,school,todo() usingNamespace("sss.bbb")["aaa"] = { msg: "你来晚了", name: "刘德华", school: "中央党校", todo: function () { alert(this.name+","+this.msg+"! 你被"+this.school+"开除了！ "); } }
