jquery $.fn 与 $.extend 的用法
$.fn 源码
jQuery.fn = jQuery.prototype = {init:function( selector, context ){};
$.fn 即原形对象给原形对象添加方法,每个jq实例都可以调用。
$.fn.copyText = function(options) { return this.each(function () { var me = this; $(this).zclip({ path:'/templates/default/images/copy-btn/ZeroClipboard.swf', copy:function(){ return $(me).data('copytext'); }, afterCopy:function(){ var d = $.alert({ content:'The code has been copied!', title:'', ok: false }); } }); }); };
$.extend 是给字面量对象jquery添加的静态方法
$.extend({ test: function(){ alert('liu'); } });
