怎样用javascript控制一个文本框的显示和隐藏？
我根据SELECT的值来控制一个 TEXT的有无？
<select name= "test ">
<option value= "1 "> 显示 </option>
<option value= "2 "> 隐藏 </option>

<input type= "text " name= "display ">

谢谢高手帮忙...

[解决办法]
$get(id).style.display= 'none '
[解决办法]
<select name= "test " id= "test " onclick= "showInput(this) ">
...
<input type= "text " id= "display "/>

function showInput(sel)
{
if(sel.value== "1 ")
{
document.getElementById( "display ").style.display= "block ";
}
else
{
document.getElementById( "display ").style.display= "none ";
}
}
