Drop down menu validation?

[Gogo82]

Hi,

I need help with a dropdown menu.

The deal is that I´ve got 2 menu´s, and I need to be able to pick one cathegory in each menu(menu1 and menu2) and press "submit" to get the info.

How do I "link" the two dropdowns together?


This is how I´ve done so far:
[HTML] <SCRIPT TYPE="text/javascript">
<SCRIPT TYPE="text/javascript">
<!--
function dropdown(mySel)
{
var myWin, myVal;
myVal = mySel.options[mySel.selectedI ndex].value;
if(myVal)
{
if(mySel.form.t arget)myWin = parent[mySel.form.targ et];
else myWin = window;
if (! myWin) return true;
myWin.location = myVal;
}
return false;
}
//-->
</SCRIPT>

<FORM
ACTION="../cgi-bin/redirect.pl"
METHOD=POST onSubmit="retur n dropdown(this.m enu1)"
TARGET="iframe" >


<div id="searchmain" >
<input name="q" value="" size="20" id="searchtext " type="text" alt="q">
<input name="ca" value="12_s" type="hidden">
<input name="th" value="1" type="hidden" />




<SELECT NAME="menu1">

<option value="">Jämtla nd</option>

</select>



<SELECT NAME="menu2">

Welcome to TSDN!

What do you mean by "linking" the two menus?

You can get the value of a dropdown select element using selObj.value where selObj is the select element.

Hi,

With "linking" I meant; 1st meny contains "country", 2nd contains "state" and then a submit button on that.

I´m a rookie at JS, and I´m having a hard time finding anything useful on the net ...please give me a script-example.

Maybe this is what you're looking for.

Thanx for now.
