jQuery Question

jQuery to submit form to new tab?

I have an action link in a form that needs to be updated with a token every minute. I get the new url/token from an api call when the user clicks on the submit button. I'm using something like this

<form id="somelink" action="http://some.external.url/" target="_blank" />

$('#somebutton').click(function(e) {
e.preventDefault();
var url = '/apicall?id=' + $('#someid').val();
$.post(url, function(data) {
$('#somelink').attr('action', data);
$('#somelink').submit();


problem is, using js/jQuery when it submits it opens in a new window without the typical menu and buttons in the browser and it's the size of a popup window.

Without the jQuery if I just clicked on the button it'll open in a new tab.

How can I accomplish this with jQuery?

Answer

Instead of catching the click event, try catching the submit event of the form and in case you find any error you can use event.preventDefault();
Update Here i tested with this code and it's working fine,

<!doctype html />
<html>
  <head>        
    <title></title>
    <script type="text/javascript" src="jquery.js"/></script>
</head>
<body>
  <form action='http://someSite.com' id='somelink' target='_blank'>
    <input type='text' name='lol' id='lol'/>
    <input type='submit'/>
  </form>
  <script type="text/javascript"/>
      $('#somelink').on('submit',function(e) {
          if($('#lol').val() == "poop"){ //Sample error check
              e.preventDefault();
              alert($('#lol').val());
          }
      });
  </script>
</body>
</html>

What this does is, if you enter "poop" it does not submit the form, for anything else it submits the form to new tab. Hope this helps :)
Update:
Regarding your comment, if in case of error you want to open some other tab, then replace e.preventDefault() with $(this).attr({"action":"http://www.someothersite.com"}); . Hope this helps :)
Update:
If you want to open a tab asynchronously, then you would have a hard time, this is the closest it can get.
HTML Part

<form id="someForm" action="about:blank" target="newStuff" />
<input type="submit" value="12345" id="someid" />

Javascript Part

$(document).ready(function() {
 $('#someForm').submit(function(e) {
    $.ajax({
        url: 'http://search.twitter.com/search.json?',
        dataType: 'jsonp',
        success: function(data) {
            if (data != "") {     
                var link = "http://www.google.com/";
                window.open(link,'newStuff'); //open's link in newly opened tab!
            }
        }
    });
 });
 });
