count number of select lists with same name?

[mattastic]

Hi,

Can anyone tell me how I can do this? I need to vaidate them before the form is sent.

I can get the html collection object by using:

var w00t = document.getElementById('equipmentlist'+i).getElementsByTagName('select');
alert(w00t.length);

Can anyone tell me how I can get the number of instances? If i use the length property it just gives me the number of options in the list.


Thankyou

just try

var w00t = document.getElementsByTagName('select');
alert(w00t.length);

[samanyolu]

alert(w00t[0].options.length);

  

<script type="text/javascript">

window.onload = function () {

var w00t = document.getElementById('mydiv').getElementsByTagName('select');

alert(w00t[0].options.length);  // 5
alert(w00t[1].length);   // 2
}

</script>


<div id="mydiv">
<select>
<option>ee</option>
<option>ee</option>
<option>ee</option>
<option>ee</option>
<option>ee</option>

</select>

<select>
<option>ee</option>
<option>ee</option>
</select>
</div>

THanks for your replies.

I still having real problems with this. Can anyone help?

I have uploaded my page here:

http://www.halesowen.ac.uk/javascript_test.cfm

All I want to do is validate the fields users enter and make sure nothing is left blank.

My main problem is adding equipment, if you click the 'add' button, you can add pieces of equipment and there quanity, I just need to make sure users dont add a piece if equipment and leave the 'please select' as selected.

I cant get javascript to access the select lists of the same name, i could then loop through them and check the selectedindex isnt set to 0.

Can anyone please help?

Thankyou
