This method simulates a mouse-click on a Button, Checkbox, Radio, Reset, or Submit form element. It does not trigger the onclick event handler for the input element.
When called on Button elements, it may (or may not) produce the visual appearance of a button-click, but it has no other effect since it does not trigger the onclick event handler for the button. For Checkbox elements, it toggles the checked property. It makes unchecked Radio elements become checked but leaves checked elements alone. When called on Reset and Submit elements, the click( ) method causes the form to be reset or submitted.
