javascript select option - help

[kbrown2974]

I am having some problems validating a select option under Javascript. Below is the code I am having problems with

vbscript to create the selection option
RESPONSE.WRITE "<b>Gender: <select name="&chr(34)&tgender&chr(34)&">"
RESPONSE.WRITE "<option selected value=M>M</option>"
RESPONSE.WRITE "<option value=F>F</option>"
RESPONSE.WRITE "</select>"
RESPONSE.WRITE "<BR>"


javascript to validate it
var checkok = "BAD";
for (var y=0; document.MyForm.tgender.length;y++)
{
if (document.MyForm.tgender[y].selected == true)
{ checkok = "OK"; }
}
if (checkok == "BAD")
{
llok = 0;
alert("Must choose a Gender");
return false;
}

The problem I am having is on the for line. I wanna check to see if the option was clicked on by the user.

Thanks
Ken

make sure that VBScript is writing the correct name for select tag

[kbrown2974]

The name of the select tag is tgender. Is there a quick little one line statement that can be used to see if the select was actually clicked on? For some reason, it doesn't appear in the post data.

The usual way to do this is to offer three options to your <select> - the first or default asks the user to select an option and will have some invalid value (say 0) so you can easily see that it hasn't been changed.

<select name=tgender>
<option value=0>M/F
<option value=M>M
<option value=F>F
</select>

still having a problem with this. If the select box is NOT selected, it is a null object. Any way I can check to see if this way selected? .length does not work, .selected also does not work.

If the select box is NOT selected, . . .
In this pattern, the invalid choice should be generated as selected.

<select name="foo">
<option value="0" selected="selected">Pick One</option>
<option value="1">First choice</option>
<option value="2">Second choice</option>
</select>
