Select SOME text from a page and use it as a var

melvynadam · Dec 16, 2004

If I open a new page with very little text on it such as
a bugmenot
results page is there a way to select some of the text there and
assign it to variables?
Selecting all and copying to the clipboard can be done with:
document.execCommand("SelectAll");
document.execCommand("Copy");
but I'm looking for something a little more refined.

The page contains seven lines of text and I'd like a simple way to say:
var username = [contents of line 4]
var password = [contents of line 5]
Can anyone point me in the right direction?

on the fly:

function getCurrentSelection(){
if (window.getSelection)
return typeof window.getSelection().toString();
else if (document.getSelection)
return document.getSelection()
else if (document.selection && document.selection.createRange)
return document.selection.createRange().text;
else
return null;
}

var sel=getCurrentSelection();

maybe it could be help you.

Thanks for the incredibly quick response! Unfortunately it's not quite
what I'm looking for - I want the process to be automated. If I have to
manually select the text it negates the point of the plugin I'm trying
to create.
I wish to open a bugmenot results page using my current location (e.g.
www.nytimes.com) with this line:
window.open('http://www.bugmenot.com/view.php?mo...=yes,menubars=no,toolbars=no,resizable=yes');
Then, in the new window I wish to automatically select the only text on
that page which changes (take a look at
http://www.bugmenot.com/view.php?mode=bookmarklet&url=http://www.nytimes.com
if you copy and paste all of the text you'll see that it's nicely
formatted and the two desired fields are on their own on individual
lines).
Later I'll want to try to return to the original page and find the
fields "user" or "username" etc. and paste back my results.

Wait, let me understand (I'm sorry, but my english is not very good)..

You have a page in a domain (http://www.nytimes.com); and you want open a
popup that points in other domain (http://www.bugmenot.com/), and after get
some information from this?

In according with SOP (Same Origin Policy), you cannot do it:

Will this help? Watch for word-wrap.
