how to get return value after form submit

Question

I want to get the return value for hid and show div after form submit success

<form id='form1' action='api.php' method='post'><input ></input></form>
<div id='layer1'></div>

I tried: Js

$('#form1').submit(function(e){ 
e.preventdefault();
$('#layer1').show();
});

It doesn't work. Is there anythings that I should return in the api.php? As I am using php5.2 I cannot using something like formdata to upload image when doing form submit.

Can anyone help?

Since you do `preventDefault()`, the form is never submitting. So there's no return value. — Barmar, Oct 08 '15 at 07:44
What doesn't work? Error message or just nothing? I notice you are mixing layer1 and #layer. If you fix that does it work as you want? — Mattias Lindberg, Oct 08 '15 at 07:44
You also have a typo in `preventDefault`. The `D` is upper-case. — Barmar, Oct 08 '15 at 07:44
If you prevent the default form submission, you need to perform an AJAX call to get the return data. — Barmar, Oct 08 '15 at 07:45
if you need some values AFTER submit you should use ajax, here is a good example: http://stackoverflow.com/questions/16616250/form-submit-with-ajax-passing-form-data-to-php-without-page-refresh — swidmann, Oct 08 '15 at 07:46
I typed layer1 and preventDefault.But after submit nothing return. It is not a ajax submit? — SFY, Oct 08 '15 at 07:47
No it's not, please take a look at my answer above, there is a link, where you can see, how an ajax submit with jQuery is done — swidmann, Oct 08 '15 at 07:49
However I am using php5.2 and the form need to submit an image. Can I use ajax to submit form with image? — SFY, Oct 08 '15 at 07:49
take a look here, this might work: http://stackoverflow.com/questions/19447435/ajax-upload-image — swidmann, Oct 08 '15 at 07:50

Instead of using origin form submit, add a listener on event 'submit'(or just as you did, invoke .submit(), no difference), then prevent default behavior, do it using AJAX. See jQuery API
