[QUOTE="RobG, post: 4928745"]
Presumably you want to know how to dynamically set an onchange handler
using a function that requires parameters, so:

object.onchange = function(){
someFunction(parm1, parm2);
}

Your next question will be 'how do I set the values of parm1 and
parm2?'.

object.onchange = function(){
someFunction('type1', 'item1');
}

Is that what you want?  You can do:

object.onchange = function(){
var param1 = 'type1';
var param2 = 'item1';
someFunction(param1, param2);
}

That creates a closure (in this case a completely unnecessary one) back
to the anonymous function, which may have complications.

Please indent code with 2 (preferred) or 4 spaces and manually wrap at
about 70 characters.  Allow for a couple of quoted replies too.

Where is optionTest declared or initialised? It doesn't seem to get
used anyway.

Where is formname initialised?

Where was items initialised?

You are better to post an example or link that is a minimal example of
what you are trying to do. Search the archives for 'dependent select
options' or 'dynamic select list'.
