(function($) { // closure $.fn.hilight = function( options ) { //将方法定义在$的fn上 var defaults = { textColor: "#000", backgroundColor: "#fff" }; var settings = $.extend( {}, defaults, options ); return this.each(function() { // Plugin code would go here... }); }; })(jQuery);
使用
$(elem).hilight(options) //或者 $.fn.hilight.call($(elem),options)
