JS实现鼠标指向后图片提示效果当鼠标移到产品缩略图上时能弹出显示大图，用JS写两个函数即可实现：
一个函数在鼠标移到图片上调用，显示隐藏层并将图片载入到层中;
另一个函数在鼠标移出图片上调用，清空层的内容并隐藏层。使用时需将"this.src"改为产品大图地址。

function showPic(sUrl){
var x,y;
x = event.clientX;
y = event.clientY;
document.getElementById("Layer1").style.left = x;
document.getElementById("Layer1").style.top = y;
document.getElementById("Layer1").innerHTML = "<img src=\"" + sUrl + "\">";
document.getElementById("Layer1").style.display = "block";
}
function hiddenPic(){
document.getElementById("Layer1").innerHTML = "";
document.getElementById("Layer1").style.display = "none";
}
</script>

<body>
<div id="Layer1" style="display:none;position:absolute;z-index:1;"></div>
<img src="/images/logo.gif" onmouseout="hiddenPic();" onmousemove="showPic(this.src);" />

<img src="/img/200406301.jpg" onmouseout="hiddenPic();" onmousemove="showPic(this.src);" />
