关于jquery 怎样让 animate不多次执行呢

loveifa 2011-08-13 10:24:04

提供一段w3c里面的教程
http://www.w3school.com.cn/tiy/t.asp?f=jquery_animation

<html>
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#start").click(function(){
$("#box").animate({height:300},"slow");
$("#box").animate({width:300},"slow");
$("#box").animate({height:100},"slow");
$("#box").animate({width:100},"slow");
});
});
</script>
</head>

<body>

<p><a href="#" id="start">Start Animation</a></p>

<div id="box"
style="background:#98bf21;height:100px;width:100px;position:relative">
</div>

</body>
</html>

大家可以先打开看一下，当点击Start Animation一次的时候有有一个动画出现。

当你快速点击5次的时候，这个动画就会显示5次，请问如果避免这种情况呢。

因为我要做一个类似 www.yilunet.com 首页这个滑动的效果。我的站上面当鼠标在三个图上面滑动多次后页面就不听的动，请高手指点如何才能做到类似www.yilunet.com这个的华东效果

这样修改即可：



<script type="text/javascript">  

$(document).ready(function(){

    $("#start").click(function(){

        if($("#box:animated").length==0)

        {

            $("#box").animate({height:300},"slow");

            $("#box").animate({width:300},"slow");

            $("#box").animate({height:100},"slow");

            $("#box").animate({width:100},"slow");

        }

    });

});

</script>

给单击事件做个判断，



$("#button").click(function() {

    if(!$("#div:animate")) {

        $("#div").animate();

    }

}

#button,就是你的按钮，#div是你想让他运动的元素，：animate是jquery选择器中选择正在运动的元素，具体参加jquery api，如果#div正在执行动画的话，那就什么都不做，如果没有在执行动画的话，那就执行你指定的动画
