How do I g开发者_Python百科et the action url from a form with jquery?

---

Get the form, ask for the action attribute:

$('#myForm').attr('action');

---

Need the full action url instead of just the basename?

Generally it's better to use prop() instead of attr() when grabbing these sorts of values. (This prop() vs attr() stackoverflow post explains why.)

However, in this instance, @JAAulde answer is exactly what I needed, but not might be what you need. You might want the full action url.

Consider this html form start tag:

<form action="handler.php" method="post" id="myForm">

attr() returns the exact action value:

$('#myForm').attr('action'); 
// returns 'handler.php'

prop() returns the full action url:

$('#myForm').prop('action');
// returns 'http://www.example.com/handler.php'

Try this one:

var formAction = $('#form')[0].action;

Or on form sumit:

 $("#form").submit(function (event) {
    event.preventDefault();
    var frmAction=this.action;
});

To use the action attribute of a form use:

$( '#myForm' ).attr( 'action' );

like @JAAulde said.

To use an entered value from a form use:

$('#myInput').val();
