jquery validation regex for digits with hyphens

Can someone provide开发者_开发问答 a regex that only allows digits and optionally hyphens

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

The following matches numbers interspersed with dashes, but not double dashes:

/^\d+(-\d+)*$/

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.

Try this plugin: Masked Input jQuery plugin. It allows to make own masks and simplifies input for user.

/^\w*-?\w*-?\w*$/

• \w* Alphanumeric character repeated 0 or many times.
• -? Optional hyphen.

Try this out...

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

Not phone numbers, but what you wanted from the comments

Check this out...

var phoneno = /^+?[0-9]+(-[0-9]+)*$/;

Ans +954-555-1234

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, '');
});

<input type="tel"></input>
