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

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})

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$)(?:\d|10)\.(?:\d|10)\.(?:\d|10)$/

am trying to validate relation field which will have alphabets, forward slash and dot for e.g
(s/o. Mr.ram or w/o. Mr.ram), i have already tried this ([a-z])/([a-z]) but it is not working
please help am new to this
thanks in advance
Just tested this in the JS console, you need to escape the slash in regular expressions.
/([a-z])\/([a-z])/
Should do it for you.

i want summarize this line in javascript!
how is it possible?
var c='['+']'+'('+')'+';'+':'+'<'+'>'+
'='+'<='+'/='+'>='+'+'-'+'&'+'*'+'/'+'=>';
I searched for character escapes but i found nothing!
I think this is what you want:
var opr_re = /\[|\]|\(|\)|;|:|<|>|=|<=|\/=|>=|\+|-|&|\*|\/|=>/;
\ is the escape character in regular expressions.

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-\"]+))#...
