Variable help

[abshah]

I have a function that has one string parameter that contains a field name from a form. I would like to place focus on that field using the passed parameter. How do I do that?

For example:

function placeFocus(fieldname)
{
document.forms[0].+ fieldname + .focus();
}

I think you can use the fieldname as an index into the elements array like this:

document.formname.elements[fieldname].focus();

If that doesn't work, what you have above is on the right track, but you have to create a string out of it, and eval it. Like this:

eval("document.formname."+fieldname+".focus()");

Both solutions worked.
