关于div自适应高度/左右高度自适应一致的js代码

复制代码 代码如下:

<div style="width:300px;">
<div id="Left" style="float:left;background-color:blue;">1<br/>3<br/>5<br/></div>
<div id="Right" style="float:right;background-color:red;">2</div>
</div>
<script type="text/javascript" src="http://jt.875.cn/js/jquery.js"></script>
<script type="text/javascript">
$(function(){
var heightLeft= $("#Left").height();
var heightRight= $("#Right").height();
if (heightLeft > heightRight)
{
$("#Right").height(heightLeft);
}
else
{
$("#Left").height(heightRight);
}
})
</script>

复制代码 代码如下:

<div id="top" style="height="200px;"></div>
<div id="box">dsafsafsafsafsafdsa</div>
<script>
window.onload=function (){
function auto_height()
{
//var h= document.documentElement.clientHeight-200;
//var high = document.getElementById("box");
//high.style.height=h+"px";
document.getElementById("box").style.height=document.documentElement.clientHeight-200+"px";
}
auto_height();
onresize=auto_height;
}
</script>
