I have a problem setting the readonly property of a textbox which depends on a yes and no radio buttons selection, I'm sure that my code is correct but i dont know why nothing happens.
This is code:
CODE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<script LANGUAGE="JavaScript">
<!-- Begin
function changeRadio(sVal) {
    if (sVal=='n')
    {
        a.textval.readonly=true;
        a.texval.value="";
    }
    else {
        a.textval.readonly=false;
    }
}
//  End -->
</script>
</HEAD>

<BODY>
<form name="a" method="post">
<table class="tabla" width="100%" border="0" cellpadding="2" cellspacing="10">
   <tr>
   <td width="32%">READONLY TEXTBOX</td>
   <td>
   <input type="radio" value="n" name="radiobtn" onclick="changeRadio('n')" CHECKED>No<BR /><input type="radio" value="s" name="radiobtn" onclick="changeRadio('s')">Yes</td>
   </tr>
   <tr>
   <td class='textoedicion' width="32%">TEXTBOX</td>
   <td><input type="text" name="textval" value='' size="21" maxlength="20"></TD>
    </tr>
</table>
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" align="center" valign="middle"><input type="submit" name="submit" value="Save"> <input type="button" name="cancel" value="Cancel" onClick="window.close()"></td>
</tr>
</table>
</form>
<script language="JavaScript" type="text/javascript">
<!--
if (document.a.radiobtn[0].checked) {
    document.a.textval.readonly=true;
}
else {
    document.a.textval.readonly=false;
}
//-->
</script>
</BODY>
</HTML>

Best regards,

Took me a couple of minutes and a little search over here to understand your problem. Javascript is a case conscious language, and so you have to write "readOnly" instead of "readonly". A very simple find and replace should solve your problem! biggrin.gif

Why does the Alert dialog box state -4bf has no properties when starting FireFox 2
Problem With The ReadOnly Property

The last 2-3 days I have been unable to access my FireFox 2 program.
The first page of the Firefox 2 program appears and then a popup box appears stating:

Alert.
TypeError: -4bf has no properties
I have downloaded a fresh copy of Firefox 2, with the same result
Please, can you help me?
