先定义两变量 移上去的定时器 和 移开的定时器

var overTimer, outTime;

$('.box').hover(function(){

overTimer?clearTimeout(overTimer):'';

outTime?clearTimeout(outTime):'';

overTimer = setTimeout('show()',1000);

},function(){

overTimer?clearTimeout(overTimer):'';

outTime?clearTimeout(outTime):'';

outTime = setTimeout('hide()',1000);

});

function show(){

$('.box').html('事件触发');

}

function hide(){

$('.box').html('悬停');

}

    
     悬停
