setFocus not working in mozilla

Question

Hi, Im using form_name.textbox.focus() and it working fine in IE but not in mozilla. Can someone tell me how to handle this? this for answering.

Answer 1

You're using a non-standard IE behavior that turns all elements with IDs into global variables.
Since Firefox does not do this, form_name is undefined.

Change it to

document.getElementById("ID of <input> element").focus();

Answer 2

Give these a go:

document.form_name.textbox.focus()
document.form_name[ "textbox" ].focus()
