Can anyone tell me meaning or possible values of below regular expression?
/(\+\d{2})/
Plus followed by a number on 2 digits.
This matches for instance: +23
A + followed by 2 digits: +23 +01 etc.

I need a Regex to match a string that must contains two positive integers separated by an undescore.
Examples:
12345_678 is Good
12345-678 is Bad
12345_678a is Bad
Thanks
^[0-9]+_[0-9]+$ will do it.
Explanation
^ the start of the string
[0-9]+ one or more digits
_ an underscore
[0-9]+ one or more digits
$ the end of the string

Can someone help me out here? I need a regex that will match the following pattern:
10-(any 5 digits except 73480)-(any 4 digits)
Examples
valid: 10-12345-1234
invalid: 10-73480-1234
Thanks
You should use negative lookahead to check for any occurance of 10-73480 before matching..
^(?!10-73480)10-\d{5}-\d{4}$
Try it here

I am absolutely terrible at regex and need to know how to determine if a value in a select is either 1 or 2, and not 0.
There are three options and only 2 are valid.
This is to be used as the validation regex for the jQuery validationEngine plugin.
Thanks in advance.
If you mean to match the literal strings "1" and "2",
/^[12]$/
will suffice.
The easiest way is to probably just check with ==, but if you really want to use regex:
var regex = /^[12]$/;

What is regular expression so that user can enter any integer or float number between 1-99.
For entering only integer I know regular expression is:
^(0?[1-9]|[1-9][0-9])$
Please tell me RE for entering integer as well as float numbers between 1-99.
A simple version is ^[1-9][0-9]?$ for integers and ^([1-8][0-9]?|9[0-8]?)\.\d+$ for floats. If you want one for both: ^(([1-8][0-9]?|9[0-8]?)\.\d+|[1-9][0-9]?)$
Test it here
Try [1-9][0-9]?(.[0-9]*)?
Edit: The above include 99.something too. This shouldn't:
[1-9](([0-8](\.[0-9]*)?)|[0-9])?
Test it here, it works. ;)

[a-zA-Z0-9-_]{3,} this is my currently using regular expression in login page. I would like to allow space in the regexp. How can i do it? I'm lack of knowledge in RegExp.
This is just a character class, so just add space at the end of the class: [a-zA-Z0-9_ -]{3,}
How about:
[a-zA-Z0-9-_\s]{3,}
This will allow all forms of whitespace...
