Disable/enable drop-down menu with radio button
|
|
| TMonk252 2005-03-08, 4:17 am |
| I'm trying to enable or disable two drop-down menus (select1 & select2) by
clicking on one of three radio buttons in the same group. I only want the drop
down menus to be enabled if the radio button with the value of "hours" is
checked. I guess I really need to know how to identify the "hours" value radio
button in my second line of javascript code (below line starting with
"if(document.form1.(". The rest of the code on that line I believe is
incorrect. Is it even possible to identify a specific radio button within a
radio group to do this? Any help would be appreciated.
Thanks.
Here's my code:
<%@LANGUAGE="JAVASCRIPT" CODEPAGE="1252"%>
<script language="javascript"><!--
function codename1(){
if(document.form1.(RadioGroup1[value="hours"]).checked)
{
document.form1.select1.disabled=false;
}
else
{document.form1.select1.disabled=true;
}
}
//-->
</script>
<form name="form1" id="form1" method="post" action="">
<p>
<label></label>
<input name="RadioGroup1" onclick="codename1()" type="radio" value="hours"
/>
<select name="select1" disabled id="select1">
</select>
to
<select name="select2" disabled id="select2">
</select>
<br />
<input type="radio" name="RadioGroup1" value="closedallday" />
Closed
<input name="RadioGroup1" type="radio" value="openallday" />
Open 24-Hours </p>
</form>

| Have a look in the forms section of www.javascriptsource.com as there are a
couple of scripts in there showing how this is done.
