It's not like I haven't googled it... But still I couldn't understand when onsubmit
is used and when onclick
is used?
They're two completely separate events.
onclick
events fire when the user uses the mouse to click on something.
onsubmit
events fire when a form is submitted. The origin of this event can sometimes be traced back to an onclick
(like clicking the "submit" button) but it can also come from a keyboard event (like pressing enter).
This implies that using onclick
on a submit button on a form might miss some cases that an onsubmit
on the form would catch.
There are many other kinds of events such as: onload
for loading resources such as scripts or images and onkeydown
for detecting key presses on the keyboard.
