jquery 插件开发:
// 定义一个JS 插件 ;(function($){ $.fn.man=function(options) { var defaults={ name:"rhythmk", age:20, url:"rhythmk.cnblogs.com" }; options= $.extend(defaults,options); this.show=function(){ alert("name:"+options.name+",age:"+options.age+",email:"+options.url); }; }; })(jQuery); //插件调用 var data={name:"wkaaaaaaa"}; var man=$.fn.man; //直接使用插件 var m=new $.fn.man(data); m.show(); //插件别名 var man=$.fn.man; var m1=new man(); m1.show();
