question about writing to an open window

[gohrnz]

OK, Im real new to all of this.

I have a form in a php file that calls it self as the processor.

Upon submission a new window is opened and the results are posted in that new window.

I would like to preload an html file into this window.

window.open('wait.html','test','height=400,width=400')

the reason I want to add this wait.html is that when the form processes there is an exec that takes a bit of time. I just wanted a please wait message in the window untill the php completes and loads the output to the window.

everything works except the loading of the wait.html. I just get a blank window until the php finishes and writes its output.

I can manually open a 'test' window with the same command and the wait.html loads fine.

Just trying to understand why opening it durring the submit will not work.

here is kinda what i have.
echo "<form method='post' action='allocate.php' target=test>";

... some more php to build form ...

echo "<input type=submit onClick=window.open('wait.html','test','height=400,width=400')>";

</form>

Any help would be greatlyh appreciated.

Moved to the lounge, since it's really a javascript question.

What happens in your application is that the wait.html is probably loaded but as you post your form to that target the page is navigated away from... You can say that your posting page is replacing your waiting page. You can solve it with frames and/or you can look upon PHPs buffering functions. Maybe that will solve your problem.

what you need to do is have your processing script display the wait message and then start processing. When it's over, refresh to the next page and you have you processing page (you can even add some dots to a line each time you process something new which will give an idea of where you are in the overall processing.
