***

form.myTextBox.value
document.getElementById("myTextBox");

hi
as per my view if in your page have a more than one form tag and have a same textbox name that time this is better way to use

form.myTextBox.value;

rather than this way.
b'cos it give you directly value from the current document

document.getElementById("myTextBox").value;

Thanks

Thank you. This clearly explains when to use what...
