Posting Form using Ajax then to form defined action

Is it possible?

[Demaestro]

I have a form.. it has an action

<form method="post" action="example.com/landing_page">

<input type="text" name="blah" value"blah">

<input type="submit">

</form>

When submitted I would like to post the form using Ajax... but after that happens I would like the form to be posted to the action defined in the form tag.

So basically it would get submitted twice.... Is this possible?

Any guide to this would be helpful.

Instead of the '<input type="submit">' consider using a '<input type="button" onclick="someAjaxFunctionCallToSubmit(someReferenceToForm)">'
and have the AJAX function call for the form to be submitted when it's done.

Another approach, though not an option if the AJAX call must come first, is to 'target' the form to a, possibly hidden, iframe and have the two submissions run simultaneously and independant of each other (or the AJAX call can be delayed), by adding a 'onsubmit="someAjaxFunctionCallToSubmit(someReferenceToForm)"' to the 'form begin' tag.

Bear in mind, not all versions of X/HTML support the target attribute.

[XtendScott]

<form method="post" action="example.com/landing_page" onsubmit="ajaxsubmit();">

function ajaxsubmit() {
.....ajax stuff here
return true;
}

This should perform both submits, you may have to perform the ajax call non-synchronous so the page waits for the ajax call to finish.

Awesome you guys thanks a lot... just got it working.

Love Ajax! Makes your sites so slick.

Ok I ran into a boo-boo

<form method="post" action="example.com/landing_page" onsubmit="ajaxsubmit();">

function ajaxsubmit() {
.....ajax stuff here
return true;
}

This works in IE, but in FF the form data doesn't get passed with the Ajax submit but does get passed to the second "hard" submit. If I set the return to false the form data is passed to the Ajax submit.

function ajaxsubmit() {
.....ajax stuff here
return false;
}

But obviously I don't get the second submition.

Any guesses?
