Js submission form

1.doc ument. forms. from. submit ();
Document. form. sumbit ();
Document. form. submit. click ();
This. form. submit ();
The above forms of js form submission do not work in the firefox browser.
2. w3c standards must be followed:
1) Use the getElementById () method to obtain the form.
2). submit the form using the. submit () method
3) The name/id of the button cannot be named "submit"
4) The name/id of all components (buttons, text boxes, etc.) in form cannot be named "submit"

# When the name or id of the submit button is submit, an error is reported when the form is submitted in js and the form name. submit (), prompting that the object does not support this attribute or method.
The solution is to modify the name or id of the submit button and do not have the same name as the submit or action.
So why does js report an error when the name or id of the submit button is submit or action? Is this a bug?
Please advise the experts ....

# I found <input type = "submit"/> and
The results are very different. Can someone tell me the differences between the two?
How can I replace the original submit button with images?

! <Input type = "submit"/> indicates a button, which is a submit button. When you click it, it automatically submits the form in which it is located.
