regular expressions in javascript:

some excerpts from

http://www.siteexperts.com:

two ways to create one
1) var daRegExp=new RegExp("pattern","switch&quot
2) (the more used) var daRegExp=/pattern/switch


then you would use it like this:

if (daRegExp.test(5)){ /*do stuff if it matches*/ } else
{ /*do stuff if it doesnt match*/}


I suppose now you are wondering what pattern and switch represent now?

pattern: there are many different ways to validate a string with a regExp. The best table is at this site:

http://www.siteexperts.com/tips/functions/ts23/page1.asp

.
I would explain it here, but it would take to long.

switch: there are three, optional switches:
g,i, and gi.

g stands for global search, and i stands for ignore case. gi then stands for global search, ignoring case.

I am not going to go into syntax, if you want that, check the website.


P.S. - email me, I have a question for you.
