jQuery实现鼠标经过事件的延时处理效果

(function($){   $.fn.hoverDelay = function(options){     var defaults = {       hoverDuring: 200,       outDuring: 200,       hoverEvent: function(){         $.noop();       },       outEvent: function(){         $.noop();       }     };     var sets = $.extend(defaults,options || {});     var hoverTimer, outTimer;     return $(this).each(function(){       $(this).hover(function(){         clearTimeout(outTimer);         hoverTimer = setTimeout(sets.hoverEvent, sets.hoverDuring);       },function(){         clearTimeout(hoverTimer);         outTimer = setTimeout(sets.outEvent, sets.outDuring);       });     });   } })(jQuery); 

$("#test").hoverDelay({   hoverDuring: 1000,   outDuring: 1000,   hoverEvent: function(){     $("#tm").show();   },   outEvent: function(){     $("#tm").hide();   } }); 

$("#test").hoverDelay({   hoverEvent: function(){     alert("经过 我！");   } });
