I want an HTML form to submit to itself. How do I use the action
attribute?
<form action="">
<form action="#">
<form action="some/address">
<form>
Which was is preferable?
In 2013, with all the HTML5 stuff, you can just omit the 'action' attribute to self-submit a form
<form>
Actually, the Form Submission subsection of the current HTML5 draft does not allow action="" (empty attribute). It is against the specification.
