Javascrit function

Hello,

when setting a field in a document to a specific value like below,

document.Form1.qnt_handmic.value = 0

Is it possible to use a variable instead of specifying the textfield 'qnt_handmic'

I have tried to illustrate what i'm trying to achieve here.

function quantity(current_texfield) {

var strname = document.Form1.current_texfield.value
if (strname > 0 ) {
document.Form1.current_texfield.value = 0
}

any help would be greatly apreciated

document.forms['Form1'].elements[current_textfield].value = 0;

That's one of the problems with usingthe easy (and non-standard) way of referencing form fields by bypassing the forms and elements collections. It only works under certain conditions, and hides the fact that there is a MUCH more flexible method that IS standard. Using the forms and elements collections you can even mix constant and variable values. For example:

var x = "A";
var y = 1;
document.forms['form'+x].elements['field'+y].value = 0;
'refers to element field1 in form formA
