Copy the all codes to a HTML file, use IE to run it, if u select "X4" , TextBox will be hidden, otherwise TextBox will be showen, good luck

一个问题，这个SAMPLE可以隐藏INPUT，但是如何隐藏INPUT前面的文本提示呢？

多谢上面两位大虾，It works. binghongcha76的SAMPLE可直接使用。<html>
<body>
<form name="myform">
<SELECT NAME="myselect" onchange="javascript:change();">
<OPTION VALUE="valueA" selected>ABCD
<OPTION VALUE="valueB">EFGH
</SELECT>
</form>
<script language="javascript">
function change()
{
var value = document.myform.myselect.value;
if(value == "valueA"){alert("test");}
else {alert("test1");}
}
change();
</script>
</body>
</html>
