Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

This is not a specific Perl problem but it relates, so please bare with me. How do I set a form button or form action to open in a new pre-sized/scrollbarred window?

I can set the target of the form to target"blank" and that works fine, it opens in a new window and everything runs beautifully. But that doesn't allow me to change the window size or anything else. Someone suggested <input type=button value="Go" onclick="javascript:window.open('post.pl','','scrollbars,width=500,height=500'); void('');"> but the problems with that are:

1) If I keep the target="blank", I have two windows that open up. If I remove target="blank", the form redirects itself to post.pl in the main window AND opens up in a new window. I just want it to open in a new window and leave the main window alone.
2) In the new onclicked window, I can't get my data to print anymore. I'm thinkink that since it's using JS to open the new window, all the form parameters are lost. Is that true? Anyone have ideas on how to fix this problem?

    This is not a Perl problem, but anyway: the window.open() method accepts a name of the new window as second parameter. This allows you to specify that window as a target for something, for example a form.

    <form target="form_results" ...>
...
<input type="submit" value="Go" onclick="javascript:window.open('','fo
+rm_results','...');void(0)" />
</form>

      So you're saying if I used print header, start_html('MyNewPage'); as the title of the post.pl, I'd write <input type="submit" value="Go" onclick="javascript:window.open('','MyNewPage','...');void(0)" /> ?

        No. You're confusing the title of an HTML-Document with the name of a frame/window. It's completely irrelevant what post.pl actually prints. Everything concerning windows happens on the clientside. The HTML i wrote already did all the necessary stuff: on submit-button-click a window is created (without content) an named "form_results" and the form has the target "form_results" which causes the browser to put the response of your post.pl into that window, if he is capable of and configured for handling multiple windows.

        This has still nothing to do with Perl.

    Do two things:
    1. In the onsubmit event of the form, open a new window with a recognizable, hopefully unique name. You can set it up however you like.
    2. Add a target attribute for the form, with this window's name as the attribute value.
    Now, the result of the query will appear in this new custom window.

    In addition, you could set the focus on this window when you open it, with the win.focus() call. This will make this window come to the front, in case it already existed.

    I wouldn't know how to make it stop redirecting in the same window, but if the data is lost in the new window maybe you could try a url_param. Instead of post.pl, use something like 
    my $forminfo = param('forminfo');
post.pl?stuff=$forminfo

    Then in post.pl, do something like: 
    my $forminfo = param('stuff');

if ($forminfo)
{
 print "Hello world!\n";
 print "$forminfo";
}

    I have no idea if this will help your problem, but if you pass the paramaters as part of the URL itself, maybe it will help.
