本文实例讲述了JS实现鼠标滑过显示边框的菜单效果。分享给大家供大家参考，具体如下：
<html>
<head>
<title>JS鼠标滑过显示边框菜单</title>
</head>
<body>
<style>
.menulines{
border:1px solid white;
}
.menulines a{
text-decoration:none;
color:red;
}
</style>
<script language="JavaScript1.2">
function borderize(what,color){
what.style.borderColor=color
}
function borderize_on(e){
if (document.all)
source3=event.srcElement
else if (document.getElementById)
source3=e.target
if (source3.className=="menulines"){
borderize(source3,"black")
}
else{
while(source3.tagName!="TABLE"){
source3=document.getElementById? source3.parentNode : source3.parentElement
if (source3.className=="menulines")
borderize(source3,"black")
}
}
}
function borderize_off(e){
if (document.all)
source4=event.srcElement
else if (document.getElementById)
source4=e.target
if (source4.className=="menulines")
borderize(source4,"white")
else{
while(source4.tagName!="TABLE"){
source4=document.getElementById? source4.parentNode : source4.parentElement
if (source4.className=="menulines")
borderize(source4,"white")
}
}
}
</script>
<table border="0" width="150" cellspacing="0" cellpadding="0" onMouseover="borderize_on(event)" onMouseout="borderize_off(event)" height="95">
<tr><td width="100%" bgcolor="#E6E6E6" height="13"><b><font size="2">导航菜单</font></b></td></tr>
<tr><td width="100%" class="menulines" height="14"><a href="#">网页特效</a></td></tr>
<tr><td width="100%" class="menulines" height="14"><a href="#">学习教程</a></td></tr>
<tr><td width="100%" class="menulines" height="14"><a href="#">网页素材</a></td></tr>
<tr><td width="100%" class="menulines" height="14"><a href="#">软件下载</a></td></tr>
<tr><td width="100%" class="menulines" height="14"><a href="#">平面设计</a></td></tr>
</table>
</body>
</html>
希望本文所述对大家JavaScript程序设计有所帮助。
