List Menu validation

MikeDee · Aug 9, 2001

If I had a list box like (below).
Is it possible to have a submit button to detect if someone has selected an option in the menu?

So if someone just press the submit without selecting an option in the menu a Javascript will alert("error&quot

;

<select name="bactivity" size="1" length="100"">
<option value="Selection" selected>Select one option</option> <option>Agriculture/Forestry/Fishing</option>
<option>Business Services</option>
<option>Central/Local Government</option>
</select>

Have a look at this, it maydo what you want:

Code:

<HTML>
<!-- CREATION DATE: 08/08/01 -->
<HEAD>
<TITLE></TITLE>

function checkIt(form)
{
   if (form.bactivity.value == '0')
      alert ('Not Selected');
}
</SCRIPT>
</HEAD>
<BODY>
<form>
<select name=&quot;bactivity&quot; size=&quot;1&quot; length=&quot;100&quot;&quot;>
<option value=&quot;0&quot; selected>Select one option</option> 
<option Value=&quot;1&quot;>Agriculture/Forestry/Fishing</option>
<option Value=&quot;2&quot;>Business Services</option>
<option Value=&quot;3&quot;>Central/Local Government</option>
</select>
<INPUT TYPE=&quot;button&quot; VALUE=&quot;Press Me&quot; onClick=&quot;checkIt(this.form)&quot;>
</form>
</BODY>
</HTML>

Slight modification to WildWill's code:

<HTML>

<HEAD>
<TITLE></TITLE>

function checkIt(form)
{
if (form.bactivity.value == '0') {
alert ('Not Selected');
return false;]{
}
else return true;
}
</SCRIPT>
</HEAD>
<BODY>
<form>
<select name="bactivity" size="1" length="100"">
<option value="0" selected>Select one option</option>
<option Value="1">Agriculture/Forestry/Fishing</option>
<option Value="2">Business Services</option>
<option Value="3">Central/Local Government</option>
</select>
<INPUT TYPE="button" VALUE="Press Me" onClick="return checkIt(this.form)">
</form>
</BODY>
</HTML>
