I'm actually looking for a javascript regex for a numeric pattern. Regex should accept any numeric input of below formats but not 0.0.0
Condition:
each segment in the pattern ranges between 0-10
Valid2.9.60.6.1010.10.100.0.1
Invalid0.0.0
Any help would be appreciated..!! Thank you...!!
Just use a negative lookahead:
/^(?!0\.0\.0$)(?:\d|10)\.(?:\d|10)\.(?:\d|10)$/

I have a simple Regex to match 'der' - /der/g
I need the context around the match. Is there any way to build the regex that way? Thank you in advance.
If you want to match the context plus the search string, simply add the optional range before and after the searched string: .{0,5}der.{0,5}
If you want to get the context only, you have to fetch it separately: (.{0,5})der(.{0,5})

how to include both digits and hyphens in javascript pattern. Like in phone number where user can add both digits and hyphens. No matter where is the hyphen.
The regular expression to make this is so simple. You can make something like this:
([0-9\-]+)
That means all numbers and hypen no matter where is. You can test it here:

i am using this regex but it still doesn't accept a 'whitespace' input. though it restricts any 'special character'..
.replace(/[0-9]|\W|^\s/,'')
Any help is much appreciated, thanks
You're looking for /[a-zA-Z\s]/. The \s covers spaces (tabs, newlines, etc.). If you literally just want a space " " then change it to /[a-zA-Z ]/.

I have a email regex . But i want to allow only 1 to 20 characters before the # symbol in the regex.
([\w-\"]+(?:\.[\w-\"]+))#((?:[\w-]+\.)*\w[\w-]{0,255})\.([a-z]{2,6}(?:\.[a-z]{2})?)
Any help would be appreciated.
You're better off checking outside of the regex, but there happens to be a way in this specific case:
(?=[^#]{1,20}#)([\w-\"]+(?:\.[\w-\"]+))#...

I want the regular expression to extract the &[1], &[2},&[3],&[4] values from the following string, with comma delimited.
var str = "Sum({[Account].&[1]+[Account].&[2]+[Account].&[3]+[Account].&[4]})";
Thanks for your help
(&\[\d+\]) Seperates them in to groups, you have to delimit them with commas yourself but that's not a big problem.. :P
Btw.: This is a great test for regex testing purposes http://rubular.com/r/0kLKf1gTaD
