Re: To get selected value from combobox

HTML doesn't have a "combobox" control. Do you mean a "select" element? If your select element has an id of "x", you would get the value of the selected option:

x.options[x.selectedIndex].value;

Proper terminology is very important in any technical discussion.

Re: return a value from javascript

you can have a hidden field in your form, and then set the value using js before it is passed to php.

PHP Syntax (Toggle Plain Text)
<script>
var hidden=document.getElementById('myfield');
hidden.value='whatever you want'
</script>
<input type="hidden" id="myfield" name="myfield" value="" />
<script>
var hidden=document.getElementById('myfield');
hidden.value='whatever you want'
</script>
<input type="hidden" id="myfield" name="myfield" value="" />
