Question

I haven’t seen a good RegEx using jQuery validate plugin that validates a phone number and extension. Does anyone have a good solution for this? The required format can be shown to the user: ie

Example: [phone] x 1234

Answer 1

// custom extension regex
phone: function(value, element) {
    return this.optional(element) || /^(1-?)?(\([2-9]\d{2}\)|[2-9]\d{2})\s*-?[2-9]\d{2}-?\d{4}(\s*x\s*\d{4})?$/.test(value);
},
