Javascript realizes the effect of changing the corresponding content below after the mouse is placed_javascript skills
This article describes the example of JavaScript realizing the effect of changing the corresponding content below when the mouse is placed. Share it with everyone for your reference. The details are as follows:
This is a relatively common menu effect on the Internet. When the mouse is placed, the corresponding content will switch, with graphic and text layout. In terms of technology, JS and CSS are combined to achieve it. You can extract the JS part of the code separately and save it as a JS file, and then introduce it into the page, which makes the main page code simpler. This effect is tested normally under IE, Firefox and other browsers.
The operation effect is as shown below:
The specific code is as follows:
<html>
<head>
<title>鼠标放上后下面的内容切换</title>
<style type="text/css">
*{margin:0;padding:0;}
a:link,a:visited{text-decoration:none;}
a:hover{text-decoration:none;}
ul{list-style:none;}
.menuA{background:#333;float:left;padding-top:2px;width:100%;}
.menuA li{float:left;}
.menuA li a{display:block;float:left;color:#fff;height:25px;line-height:25px;padding:0 5px;margin-left:2px;}
.menuA .check a {background:#fff;color:#000;}
.menuB{clear:both;border:2px solid #000;border-top:none;background:#fff;}
.menuB ul{display:none;padding:15px;line-height:180%;}
</style>
</head>
<body>
<div class="menuA">
<ul>
<li class="check"><a href="#">国际时事</a></li>
<li><a href="#">精美壁纸</a></li>
<li><a href="#">大国关系</a></li>
<li><a href="#">欧美风情</a></li>
</ul>
</div>
<div class="menuB">
<ul style="display:block;" class="one">
<li><a href="#">国际时事</a></li>
</ul>
<ul class="one">
<li><a href="#">精美壁纸</a></li>
</ul>
<ul class="one">
<li><a href="#">大国关系</a></li>
</ul>
<ul class="one">
<li><a href="#">欧美风情</a></li>
</ul>
</div>
<script>
function $_class(name){
var elements = document.getElementsByTagName("*");
for(s=0;s<elements.length;s++){
if(elements[s].className==name){
return elements[s];
}
}
}
var tabList = $_class("menuA").getElementsByTagName("li")
tabCon = $_class("menuB").getElementsByTagName("ul");
for(i=0;i<tabList.length;i++){
(function(){
var t = i;
tabList[t].onmouseover = function(){
for(o=0;o<tabCon.length;o++){
tabCon[o].style.display = "none";
tabList[o].className = "";
if(t==o){
this.className = "check";
tabCon[o].style.display = "block";
}
}
}
})()
}
</script>
