How to allow only "numbers","-" and "()" using JavaScript

Question

I have to do phone number validation using JavaScript.
I have already done validation for numbers as follows,

  
var filter =/^[0-9]+$/

But now I have to also allow hyphen and "()".
Please provide me a way for the same.

How about:

/^[0-9()-]+$/

Notes:

Parenthesis have no special meaning in a character set
If you start, or end, with a minus-sign, it is not interpreted as a range, but as the minus-character itself
