Hello,
after a hole day I finally achived to grab information via GM_xmlhttpRequest ...

This information is a piece of string placed into a variable.
eg. var found = "whatsoever"

Now inside of the whole GM_xmlhttpRequest - routine I can change/use... it. BUT I need it in another part of the script outside of this routine.
Even if I made 'found' global from the scripts beginning it will not be affected by the response result and stay an independent variable of it's own.

How can I make (export/transfer) a result from an xmlhttpRequest be available in the later script?

greets ~ V

GM_xmlhttpRequest({
method: "GET",
url: "https://www.google.com/",
headers: {
"User-Agent": "Mozilla/5.0",
"Accept": "text/xml"
},
onload: function(e) {
r=e.responseText;
test();
}
});

works perfectly
and use GOOGLE next time to save you (and us) a day
search for other errors in your script

Thanks for your quick reply - and sorry that it took you 2 minutes time.

I have been searching many scripts and references, also the guide etc. but I won't ask g00gle.

Ok - trying your example (with a different url) and appending
alert('r.: '+r);
behind your example: r stays just as empty as my variable.

that's because GM_xmlhttpRequest is asynchronous
onload is executed after your alert
to see this try putting an alert in onload

Yes - I wrote it above - I have no problem INSIDE GM_xmlhttpRequest but I need the result in another part of the script.

use callbacks, events, things like that

Great - a completely different topic to work through - so some more days until that (incl. all ref-links ect.) again is grasped. And then search for the hidden connection to xmlhttpRequest ....

That's what I'm doing all the time - and when I'm so stuck like now I dare to ask this forum.
I know it's more succsessfull to request complete scripts .... it's so frustrating.

later: Got it - explanation follows after break

If you want to make a variable global from inside a function, just use

function foo(){
window.variable="test"
}
