代码

<script language="javascript" type="text/javascript">
    <!--
        window.onload=window.onresize=function()
        {
            if(document.getElementById('RDiv').clientHeight<document.getElementById('LDiv').clientHeight)
            {
                document.getElementById('RDiv').style.height=document.getElementById('LDiv').offsetHeight+"px";
            }
            else
            {
                document.getElementById('LDiv').style.height=document.getElementById('RDiv').offsetHeight+"px";
            }
        }
    -->
</script>

<div id="LDiv" style=" float:left; width:150px; background-color: #E6E6E6;">
</div>
<div id="RDiv" style=" float:left; background-color: #E9F4FF;">
