jquery same label multiple same event return statement form Submit instance

If the submit,a tag of the form form comes with a single mouse click event, we can actually add additional click events

such as: $ (': Submit '). Click (); The custom Click event executes first, then the click event that comes with the label, and if there is a return false in the custom event function, the event that the label comes in does not take effect, and a return true takes effect

This is often used to do form validation because the entry is incomplete or the error is not allowed to be committed
