Dynmic form buttons

[subBlue]

I have a form that has a set of buttons that i want to change the appearance of when they are clicked. I can do this by specifying the button name directly, but i'd like to be able to do it with dynamically. For example:

I can do this:

formObj.button1.value += "*";
formObj.button2.value += "*";

etc etc

But i want to do something like this (which doesn't work!)

whichbutton = "button" + bnumber;
formObj[whichbutton].value += "*";

I gues it doesn't work because i'm trying to specify an object with a standard variable, so how do i change it to make it work?

Cheers.

Hi Tom,

Use the eval() for what you want

for (i=1; i <= numOfButtons; i++)
{
myButton = eval('document.formname.button' + i);
myButton.value = "*";
}
