Submit multiple forms to various iFrames

due to security and implementation reasons that are out of the scope of this post, I need to submit multiple forms in a single page to different iFrames (one iFrame for each form). I can't use jQuery nor AJAX, it has to be done via:

<script>
document.Form1.submit();
</script>

The problem is, after I submit the first form (everything goes well), I can't submit the other three forms. I'm guessing only one form.submit() call is allowed per page. Is there a way around this?? I have no problem with submitting all the forms at the same tim开发者_开发知识库e.

Ps: I'm forwarding the post request to the iframe using the target param of the form. Like this:

<form id='Form1' name='Form1' action='https://www.xxx.com/index.php' method='post' target='iFrame1'>

Thanks a lot in advance for your time and help. Best regards,

You can also have multiple forms and have each form submit to a separate iFrame.
