var test = string2.substri ng(string2.leng th,string2.leng th-7)
if (test == 'welcome')
{alert('It has welcome at the end')}

This way it looks cutier :)
alert("lala welcome".substr (-7).toLowerCase( ) == "welcome");
But I preffer using the regexp, it's more compact :b
alert(/welcome$/i.test("lala welcome"));

I prefer that too, because the former would display "false" in MSIE6
and "true" in FF1.

It's true, I forgot that IE was different about substr, this works on
both :]
alert("lala welcome".slice(-7).toLowerCase( ) == "welcome");

Of course the word "welcome" is likely to followed by a full stop ("."),
or a space(s) in a real world situation.
/welcome\.?\s?$/i
Something like that, not tested.

Yes :]
/welcome\.?\s?$/i
Maybe the "\b" will fit better :]

Thanks a lot! I'm sorry that I didn't describe my problem exactly, The
pattern I want to match is actually is :
I want to match all the pages of the site www.raphsy.com but the home
page www.raphsy.com/welcome.html
so one Regexp maybe: str.match(/^www\.raphsy\.c om\//) &&
!str.match(/welcome\.html$/)
but I don't want to use two bool expression, I want to combine the two
expression in one RegExp, that's to say: how to negate a pattern(like
/welcome\.html/) in RegExp?
Appreciate your help!!

And does it have to be compatible with all browsers that understand
RegExps? If so, consider
OK = !!str.replace(/welcome.html/, "\u20A4")
.match(/^www\.raphsy\.c om\/[^\u20A4]/)
Few modern pages will have \u20A4 anywhere, let alone in the URL.
It's a good idea to read the newsgroup and its old FAQ. See below.

Hi All,
I have encountered problems with JS RegExp.exec() and can't find what
is the problem. Could you help me?
formRequest is a function that extracts some information from
XMLHTTPRequest response. A very strange effect (and I can't find where
I've done something wrong) is that regexp matches in this function fail
on every second call.

Hi, All,
I encountered this strange problem while using function preg_match.
The following is the php code.
when I set the line:
$text = str_repeat('*', 12500);
preg_match will return 0 for the hard coded regular expression.
but if I set $text to 12499, it will return 1 for a match.
$text = str_repeat('*', 12499);

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
