DIV等高JS控制

代码 window.onload = function()
{
     var prodcut = document.getElementById("productDIV")getElementsByTagName("div");
     var len = prodcut.length;
     var h1;
     var h2;
     for(var i=0;i<len;i++)
     {
         var a=i;
         var b=++i;
         if(h1<h2)
         {
            product[a].style.height=h2+"px";
         }
         else
         {
            product[b].style.height=h1+"px";
         }
     }
}

HTML结构

<DIV id="product">

<div>faslkdjfkas

</div>

<div>124321342342</div>

</div>
