open new window with javascript and send POST parameters

Question

I would like to open a new window with javascript and pass POST parameters to it. I've tried a lot of things.

My latest code looks like this so far, but not working (I haven't tried to pass post parameters but after it will work I can only add hidden input to make it work. I guess.):

<form method="POST" name="showgraph" onsubmit="javascript:window.open('graph.php', 'Graph', 'scrollbars=yes,titlebar=no,top=300,left=400');" action="javascript:void(0)">
<a href="#" onClick="document.showgraph.submit();">Show graph</a>
</form>

Replace `action="javascript:"` with `action="graph.php"`, remove `onsubmit=...` and add `target="Graph"`. The form will be opened in a new tab/window, depending on the user's preference. — Rob W, Jul 13 '12 at 10:54

You need to create hidden form with target="_blank" and submit it with javascript. It is not possible to pass POST parameters using window.open method. For more details visit this link

If you have control over the initial page, why not just creat JavaScript variables with PHP?

<script type="text/javascript">
<?php

foreach ($_POST as $key => $val)
{
    echo "var php_$key = $val;";
}

?>
</script>

Then, you can pass the js vars in the query string of the URL parameter of window.open.
