regular expression

Hi,

Does anyone has a sample of how to validate a value using regular expressions.

I want to know if a field value contains any of this 9 characters.


" # + ' / ; < > \

Thanks

var myRE = new RegExp("[\"#+'/;<>\\]+","g");
if ( myRE.test([i]testString[/i]) ) then
   alert("Found special character");

Thanks for the quick response looks like everythingworks OK
except the \ I try to fixed but no luck. I get the error

error: expected "]"m in regular expresion.

Using a backslash in any regular expression is problematic - since it has such a strong meaning. Usually using two \\ in a row is the proper way to signify a literal \, but not with every language. Did you try using just a single \ there at the end? May be if the character after it has no special meaning when escaped by \ it will interpret the \ as literal.

Unfortunately the regular expression page in MSDN is no help. It doesn't even mention using \ to escape characters which have meaning into regular characters.

It also may be that escaping the quote with \ is unnecessary with a character class (i.e. the [ ] ), so it is already picking up the \ from there. Guess I can try to do some experimenting...
