jQuery聚合函数实例
本文实例讲述了jQuery聚合函数。分享给大家供大家参考。具体如下:
(function($) { $.fn.aggregate = function(seed, func) { var _r = seed == null ? "" : seed; this.each(function(index, element) { _r = func(_r, element); }); return _r; }; $.fn.count = function() { return this.aggregate( 0, // seed function(result, _) { // func return result + 1; }); }; })(jQuery); alert($("a").count());
希望本文所述对大家的jQuery程序设计有所帮助。
