Syntax
Description
The
onsubmit attribute is used on the form element only. Its purpose is to capture
the moment when the form is submitted, following the moment when the user
activates the form’s Submit
button.
Example
This attribute is used
almost exclusively for the purpose of running form validation scripts. In
such scenarios, the user fills in the form and clicks submit, at which
point the onsubmit attribute triggers the form
validation routine, and the form is either submitted, or cancelled because
of an error of which the user is alerted:
<form name="frmPersonalDetails" action="/personal.php"
onsubmit="checkPersonalDetails();"> ⋮ </form>
Value
This attribute has no fixed value.
It’s up to the author to decide on the scripting that’s included here, be
that a call to one or more defined functions, or a simple
alert() statement.
