jquery validation regex for digits with hyphens

Can someone provide a regex that only allows digits and optionally hyphens

I have got as far as phone_number.match(/[0-9-]/); but with no luck

I recently developed a regex pattern for my assignment which exactly matches 999-999-9999.

/^\d{3}-{1}\d{3}-{1}\d{4}$/

^ asserts position at start of a line
\d matches a digit (equivalent to [0-9])
{3} matches the previous token exactly 3 times
- matches the character - with index 4510 (2D16 or 558) literally (case sensitive)
{1} matches the previous token exactly one time (meaningless quantifier)
\d matches a digit (equivalent to [0-9])
{3} matches the previous token exactly 3 times
- matches the character - with index 4510 (2D16 or 558) literally (case sensitive)
{1} matches the previous token exactly one time (meaningless quantifier)
\d matches a digit (equivalent to [0-9])
{4} matches the previous token exactly 4 times
$ asserts position at the end of a line

Here is the solution for a input with hyphens

$('input[type="tel"]').keyup(function() {
  this.value = this.value
    .match(/\d*/g).join('')
    .match(/(\d{0,3})(\d{0,3})(\d{0,4})/).slice(1).join('-')
    .replace(/-*$/g, '');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="tel"></input>

What you're describing is used in the jquery validate plugin http://docs.jquery.com/Plugins/Validation/CustomMethods/phoneUS

^(1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})-?[2-9]\d{2}-?\d{4}$

I came here searching for something similar and found what I needed at http://regexlib.com/ they have a great collection of expressions as well as a helpful cheat sheet.
