Nihar - it’s not really designed to be manipulated via JavaScript.

Anyway - here is some code that might do it. I have not tested it, so it may have some small bugs.

function getSelectedInputs(select_name){
var inputs=[],selected_inputs=[],els=document.getElementsByTagName(’input’),i;
{
for(i in els)if(els[i].name==select_name+’[]‘)inputs[inputs.length]=els[i];
for(i in inputs)if(inputs[i].checked)selected_inputs[selected_inputs.length]=i;
return selected_inputs;
}

the above should return an array containing the indices of the selected inputs.

Hi,
Can you pls let me know how to get the values of the checkboxes selected?
I can’t grab those in a java script function.
Pls make an early reply.

Thank you. Someday, I’ll get around to the rewrite I’ve promised, but it is good that this old code is still useful!

This is a great script! It does wonders for cleaning up and simplifying information collection for me.

Thanks for the time and effort. It’s very much appreciated.

Hi Scott, I’ve added a new function to the code. it’s called “multiselect_hasSelected(name)”. it should return true if there is a selection, and false if not. I haven’t tested it, but it should work fine (it looks okay to me).

I think it’s time I rewrote this… maybe I’ll do it tonight.

I have another question for the javascript gurus here. On the form where I have this script implemented I need to force the user to make at least one selection from the list. When the form is submitted I run a javascript function that is suppose to check the elements marked as required to be sure they have a value. I’ve tried various scripts that I found on the web that is suppose to check SELECT MULTIPLE elements and I cannot seem to get them to work when this script is in place.
Can anyone provide such a quick function that is known to work with this script?
Thanks again.

Nevermind… it helps to read what others write….. sorry, I now see that update from John two posts up from mine and have that working now also. Thanks everyone for the hard work. This script is sooo cool. Keep up the good work.
