Get a form action/url with jquery

问题:

How do I get the action url from a form with jquery?

回答1:

Get the form, ask for the action attribute:

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

回答2:

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'

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();

回答4:

Try this one:

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

Or on form sumit:

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