onChange value

Got a simple list that when the options change it fires an function ajaxcall.

Is it possible to put the value of the change and other lists in?

So for example, current code is:-
<select name="select1" size="5" STYLE="width: 150px" onChange="ajaxcall('catSel2.php',ajaxCat1,'catSel2');">
<select name="select2" size="5" STYLE="width: 150px" onChange="ajaxcall('catSel2.php',ajaxCat1,'catSel2');">

Id like it to say something like:-
<select name="select1" size="5" STYLE="width: 150px" onChange="ajaxcall('catSel2.php?select1=' . select1.value . '&select2=' . select2.value . ',ajaxCat1,'catSel2');">

Any ideas?

Thank you

Try adding ids along with the names, then:

<select name="select1" id="select1" size="5" STYLE="width: 150px" onChange="ajaxcall('catSel2.php?select1=' + document.getElementById('select1').value + '&select2=' + document.getElementById('select2').value + ',ajaxCat1,'catSel2');">

There are other ways to do this, but this is clear enough.  Also, note that + is used for concatenation.
