Question

Someone tell me the difference between .submit() vs :submit. When & where to use with a simple example please.

Thanks

Answer 1

.submit() is a method. That means you need to call it when you want to trigger a form submission

$("#form").submit()

:submit is a selector helper to find specifically buttons that submits

$("button:submit")

You can find very valuable examples on the jquery doc pages linked in my answer.
