I have simple form.
<form target="_blank" action="somescript.php" method="Post" id="simpleForm">
<input type="hidden" name="url" value="http://...">
<input type="hidden" name="code" value="wrxosf">
</form>
...and there are some anchor link
<a href="#" onclick="$('#simpleForm').submit();return false;">Do it!</a>
It works fine in FireFox or IE, but Google Chrome. Chrome does once, then link become unclickable.
onsubmit = function () { if (allowSubmit) allowSubmit = false; else return false; } })(); (well, as sure-fire as you can get with JS enabled anyway). You could disabled the button as a visual confirmation to the end user that the form can only be submit once too. Very correct.
Also had such problem.
The decision was to add something random to URL each time before submitting.
HTML:
<form action="go.php" method="post" target="_blank" id="go">
...
</form>
JavaScript (jQuery):
$('#go').attr('action','go.php?'+Math.random()*1000).submit();
Forms with target="_blank" submiting only once. This is webkit & chromium bugs.
