通过上一个基础篇我们知道插件的格式，这次我来写一个tab插件
$(function() { $.fn.插件名称 = function(options) { var defaults = { Event : "click", //触发响应事件 msg : "Holle word!" //显示内容 }; var options = $.extend(defaults,options); var $this = $(this); //当然响应事件对象 //功能代码部分 //绑定事件 $this.live(options.Event,function(e){ alert(options.msg); }); } });
直接贴代码：
