jQuery extend
Java代码 收藏代码 (function($){ $.fn.extend({ pluginName:function(opt,callback){ // Our plugin implementation code goes here. } }) })(jQuery); 形式2: Java代码 收藏代码 (function($) { $.fn.pluginName = function() { // Our plugin implementation code goes here. }; })(jQuery); 上面定义了一个jQuery函数,形参是$,函数定义完成之后,把jQuery这个实参传递进去.立即调用执行。这样的好处是,我们在写jQuery插件时,也可以使用$这个别名,而不会与prototype引起冲突.
(function($){ $.fn.extend({ pluginName:function(opt,callback){ // Our plugin implementation code goes here. } }) })(jQuery);
jQuery.fn.extend(object); 给jQuery对象添加方法。 jQuery.extend(object); 为扩展jQuery类本身.为类添加新的方法
$.validator = function( options, form ) { this.settings = $.extend( true, {}, $.validator.defaults, options ); this.currentForm = form; this.init(); }; $.extend($.validator, { }) $.fn.validator = function( options, form ) { this.settings = $.extend( true, {}, $.validator.defaults, options ); this.currentForm = form; this.init(); }; $.extend($.fn.validator, { })
