Putting data into a variable from a popup window or frame

[Rune Hammerskov]

I have a javascript where the following line is used prompt the user for
a url.

# szURL = prompt("Enter a URL:", "");

The problem is that I would like to open a php script instead of the
prompt. In that php script the user should then be able to select a link
and the information passed back to the 'szURL' variable.
Is this possible?

If you now have

szURL = prompt("Enter a URL:", "");
// do something with szURL ...

then use instead of that

window.szURL = -1; // or any other value that indicates no selection
window.open("example.php");
function continue() {
// do something with window.szURL ...
}

and in the document your PHP script creates something like

if (opener
&& !opener.closed
&& typeof opener.continue != "undefined"
&& typeof opener.szURL != "undefined"
) {
opener.szURL = ...
opener.continue();
self.close();
}
