How to use javascript to access item VALUES on a portal form

Question

Hi,
I want to pick up VALUE of an item on a portal form from the on click event of the save button. I know there is a way to acces the item name and assign a value to that item. For example,
setItemValue(this.form,'UNIT_NAME', this.value)
If I use this line of code then I get the value of the save button because I put this line of code in the on click event of the save button. Please help.

You can get hold of any field on your form as follows:
document.forms[0].elements['<form>.DEFAULT.<field>.01']
So for example to get (or set) a value in my form I have:
document.forms[0].elements['REQUESTFRMEU.DEFAULT.BUS_OBJ.01'].value
Note that setting a value of a field with Javascript on the Insert button's onclick event will not result in the new value being sent to the DB. I think it has to do with the values being set into a session object of sort and the DB gets updated from these values and when you update the field with JS it does not update thesee session values. If you set the value somewhere else (e.g. another event handler before the Insert button is clicked) you should be OK.
