How can I get a variable from one form into a javascript popup window?

Question

Using the code below, I'd like to post or get the value returned (date) into a javascript window so that I can run a query off of the value. Can someone please tell me how to do this?

<form method="post" action="search.html">
  <p style="padding:10px;">
    <input type="text" id="date" name="date" value="" maxlength="10"><a href="javascript:void(0);" onclick="g_Calendar.show(event, 'date', 'yyyy-mm-dd')" title="Show Calendar" style="text-decoration:none;">&nbsp;<img src="calendar.gif" class="cp_img" alt="Open Calendar" style="padding-bottom:3px;"></a><br /><br />
    <input type="submit" name="search" value="Submit">
  </p>
 </form>

Is this just not possible??

Answer 1

Using the target attribute of <form> will allow you to post data to a new window directly.

<form method="post" action="search.php" target="newpopup">
  <p style="padding:10px;">
    <input type="text" id="date" name="date" value="" maxlength="10"><a href="javascript:void(0);" onclick="g_Calendar.show(event, 'date', 'yyyy-mm-dd')" title="Show Calendar" style="text-decoration:none;"> <img src="calendar.gif" class="cp_img" alt="Open Calendar" style="padding-bottom:3px;"></a><br /><br />
    <input type="submit" name="search" value="Submit">
  </p>
 </form>

I am assuming that you are catching the data posted at search.php.

target also accepts _top, _blank, .. so on.

using the jQuery Form Plugin you could submit your form ajax-ily, and receive a return success event and values that you could easily pass in querystring of a window.open call and get the result you seek...

Thats just one way...

Another way is not use forms and submits, but just do a ajax post to php service and receive json results and pop up window or thickbox or whatever ..

If you can take your value to search.php, then you could store it in a session variable and recatch it from that session variable in your popup window.
