Issues with submit button

Question

Is there any difference between these two ways:

1) <form name=form> <input type=submit > </form>

2) document.form.submit();

Does it send any interrupts by clicking on submit button or by javascript.
Kindly let me know the major differences between these two ways of submit

Answer 1

When you submit with a submit button it will send the name of the submit button to the server, it can't happen if you submit with javascript.

Besides of this, I don't think there is a difference.
