Javascript Regex UK Phone Number

Posted on by CU21020959-0 2,601

I'm validating a phone number on entry in CRM.  Could someone give me an example of the regex they're using if they're doing something similar.

Ideally a regex for mobile and one for landline, or otherwise a single one to cover both.

Thanks

    function showActivitiesReport() {
        //Get iframe
        var iframeObject = Xrm.Page.getControl("IFRAME_AllActivitiesReport");

        if (iframeObject != null) {
            var accountId = Xrm.Page.data.entity.getId();
            var strURL = "/crmreports/viewer/viewer.aspx?"
        + "action=run&context=records&helpID=Organisation%20Activities.rdl&"
    + "id=%7badcfa60f-526d-e711-810a-5065f38b06f1%7d&records=" + accountId + "&recordstype=1";


            //Set URL of iframe
            iframeObject.setSrc(strURL);
        }
    }

    I found sample Regex's for both landline and mobile numbers.  They only work if the spaces are stripped out of the numbers.  These are the 2 functions I then created:

    function Lib_IsValidMobileNumber(p) {

       p = p.replace(/\s/g,'');

       var mobileRegEx = /^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/;

       return mobileRegEx.test(p);

    }

    function Lib_IsValidLandlineNumber(p) {

       p = p.replace(/\s/g, '');

       var landlineRegEx = /\s*\(?(0[1-6]{1}[0-9]{3}\)?[0-9]{6})\s*/;

       return landlineRegEx.test(p);

    }

    This is what I used for a mobile phone regex with Javascript

    (070|071|072|073|074|075|076|077|078|079)\d{7,8}$

    it makes sure the the number begin with 07 and then it has 7 or 8 digits.  Apart from that, there isn't a great deal of validation you can do with phone numbers.

    I also removed brackets and replaced international codes with a zero, so they didn't cause problems with the regex expression
