You can add Pop-Up functionality to a web page quickly and easily with a little Javascript. This is useful for help screens or any other informational screens where you don’t need a browser window with full functionality and you don’t want to lose your existing page.To do this, add the following to the <HEAD> portion of your HTML document:
< SCRIPT LANGUAGE="JavaScript" type="text/javascript>
< !-- Begin
function popexternal( h ) {
if( h ) {
var offsite = window.open( h, "offsite", 'width=800, height=600, left=5, top=5, menubar=no, scrollbars=yes, resizable=yes, toolbar=no' );
offsite.focus();
}
}
// End -->
< /SCRIPT>
Then set up your href links like this:
<a href="javascript:popexternal( '/help.html' )">HELP!</a>
This will open a new browser window with the geometry specified in the ‘function’ and display the relative URL ‘help.html’.
In Perl, you can add the same Javascript function to your page like this:
my $jscript =<<END;
function popexternal( h ) {
if( h ) {
var offsite = window.open( h, "offsite", 'width=800, height=600, left=5, top=5, menubar=no, scrollbars=yes, resizable=yes, toolbar=no' );
offsite.focus();
}
}
END
# Page header, etc
print header, start_html(-title => "Basic Web Page ",
-script => {-language => 'JAVASCRIPT', -code => $jscript},
);
As of this writing, this method of generating a pop-up is NOT captured by Windows XP SP2’s pop-up blocker.
