Make Browser Dialogue Box Pop Up.

[Gazza]

Hi,

I want to make a web page that causes the user's browser to pop a dialogue
box onto their screen with a message of whatever I want (such as 'Thanks
for visiting this site!'). The box should include a 'close' button to get
rid of it. Would the web page wait until the box had been closed before
loading or would it load in the background? What HTML tags would I need to
use? Or would I have to use a Perl CGI script to do this (to send a
special HTTP header, say)?

Yours,
Gary Hayward.

The usual way of doing this is to use JavaScript - see the alert() function.
Some people have JavaScript disabled, a small but still significant
minority. See:
http://www.w3schools.com/js/default.asp for an intro to JavaScript.

By the way, needless popups are one of the most annoying things on the web,
and may discourage return visits.

Hi,

Thanks.

You are right about pop-ups having the potential of being annoying and I
assure you that I don't actually intend to use a pop-up in the trivial way
described; I just gave a simple example of the type of thing I wish to do
without going into unnecessary detail. Here, though, is what I do intend
to do.

On my computer, I have created and run as a daemon a BASH script that checks
my computer's Internet IP address and, when it changes, creates an HTML
page including it that it then uploads to one of my Internet-hosted web
sites. The page on the web site is password protected thanks to a Perl CGI
script that I wrote. Everything works fine, but then decided I wanted the
IP address not in the web page (which could be saved by the user and could,
therefore, potentially be accessed by someone able to access the computer
that saved file was on but unauthorised to do so), but popped up in a
browser dialogue box of the user. I guess there is no way of stopping the
user from dragging their mouse pointer over the IP address in the dialogue
box with the left mouse button pressed down and copying and pasting it in a
file, though, is there?

In Windows at least, I'm pretty sure that the text in an alert window is
not selectable. But obviously there's no way to stop them from writing
it on a piece of paper, or manually typing it into a file.

....which is maddening when one is trying to capture details of an
error report...

Or take a screen shot, and feed it to text recognition software.
