<title>js+CSS实现表格渐变</title>
<style>
#tip{
position:absolute;
left:90px;
width:0px;
height:0px;
color:#FFF;
font-size:12px;
background-color:#000;
border:1px solid #DEF;
filter:Alpha(Opacity=0);
opacity:0;
z-index:999;
}
</style>
<script type="text/javascript">
<!--
//定义“获得指定dom节点”的函数，因为其重用率高
function $(d){return document.getElementById(d);}
//控制div逐渐显示
var i = 0;
function change_show(){
var obj = $("tip");
i=i+5; //逐渐显示速度
obj.style.filter = "Alpha(Opacity=" + i + ")"; //透明度逐渐变小
obj.style.opacity = i/100; //兼容FireFox
if(i>=100){
clearInterval(s);
i=0;
}
}
//控制div逐渐消失
var j = 100;
function change_hidden(){
var obj = $("tip");
j=j-5; //逐渐消失速度
obj.style.filter = "Alpha(Opacity=" + j + ")"; //透明度逐渐变大
obj.style.opacity = j/100; //兼容FireFox
if(j<=0){
clearInterval(h);
//obj.style.display="none";
j=100;
}
}
//控制change_show()行为
var s;
function show(){
if(s){clearInterval(s);}
$("tip").style.display="block";
s = setInterval(change_show,1);
}
//控制change_hidden()行为
var h;
function hiddentip(){
$("tip").innerHTML="";
h = setInterval(change_hidden,1);
}
//-->
</script>
</head>
<body>
鼠标滑过这里，渐变出现
<div id="tip" style="background-color:blue;width:48%;height:48%;" onmouseover="show();" onmouseout="hiddentip();">
</div>
</body>
</html>
