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
[解决办法]
var dg = function(id){return document.getElementById(id);} 试试
