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。
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>好玩的鼠标指向后带图片的提示效果</title> <script language="<a href="http://www.xgdown.com/article/239/ArticleList239_1.htm" target="_blank" title="Java技巧">Java</a>script"> 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> </head> <body> <div id="Layer1" style="display:none;position:absolute;z-index:1;"></div> <img src="/images/logo.gif" onmouseout="hiddenPic();" onmousemove="showPic(this.src);" /> <p></p> <img src="http://www./img/200406301.jpg" onmouseout="hiddenPic();" onmousemove="showPic(this.src);" /> </body> </html>
