求助ver xx = document.getElementById 问题
现在代码：

if( document.getElementById( "name ") )
{
document.getElementById( "div_name_ ").innerHTML = "Please Insert Name! " ;
document.getElementById( "name ").focus();
return false;
}


想改为：
----------------------------

var dg = document.getElementById
if( dg( "name ") )
{
dg( "div_name_ ").innerHTML = "Please Insert Name! " ;
dg( "name ").focus();
return false;
}

----------------------------

在IE下好用，FF下所有效果丢失

------解决方案--------------------
var dg = function(id){return document.getElementById(id);} 试试
