Why do you have `(?=.*[a-z])`? Also you need to escape `[]` in a character class. — Jerry, Sep 16 '13 at 15:05
Duplicate. This question gets asked a lot. I'm partial to my own answer(s). See: "[regex for password](http://stackoverflow.com/a/9611715/433790)" and "[Regular expression for a string that must contain minimum 14 characters, where at minimum 2 are numbers, and at minimum 6 are letters](http://stackoverflow.com/a/5527428/433790) — ridgerunner, Sep 16 '13 at 15:29

For the rules you mentioned:

/^(?=.*[0-9])(?=.*[A-Z])(?=.*[^a-zA-Z0-9])/;

This should suffice.

[^a-zA-Z0-9] matches anything that is not an alphabet and not a number, i.e. a special character.

I removed the case insensitive flag because you specifically mentioned there should be 1 uppercase letter.
