To create Regex for a phone number field

[Gulzar Manuja2]

Dear All,

Greetings !!!

I have a requirement to create a Phone Number variable on a catalog item which is supposed to follow E164 format. Since E164 type is not available on a catalog item, I have created a Single Line Text type field, however, I am facing issues while creating Regex for this field. My requirement is to allow users to enter numbers, spaces and special characters such as brackets, hyphen, plus sign. On top of that, they should not be able to enter alphabets in this field. A few valid examples of valid phone numbers are:

1. +1 (201) 515-1633
2. +919876543210
3. 9876512345
4. 201-515-1633
5. 987 654 321

I would like to keep spaces and special characters(brackets, plus sign, hyphen, spaces) to be optional. I have tried creating Regex for this requirement but apparently I haven't able to create the correct one. Could someone help me to create Regex for this requirement please?

Thanks & Regards,

Gulzar Manuja

The advantage of doing this as a "Question Regular Expression" is that is reusable throughout the catalog without having to introduce a client script on every catalog item.  My catalog has multiple items where there is some sort of phone variable, and there are more to come.  If I have a regex value for phone, I just have to select a drop-down value for the phone variable.

Hello ,

For validation you have to create on change client script on mobile number field

Attaching screen shot for the same

 

******************code snippet********************

function onChange(control, oldValue, newValue, isLoading) {
if(isLoading || newValue == ''){
return;
}
// Allows formats of (999) 999-9999, 999-999-9999, and 9999999999
var pattern = /^[(]?(\d{3})[)]?[-|\s]?(\d{3})[-|\s]?(\d{4})$/;
if(!pattern.test(newValue)){
alert('Phone enter a valid phone number');
g_form.setValue('u_mobile_number', '');
}
}

Hey,

I think there is a no code way to achieve this:

Follow below article for the same:

Feel free to mark correct, If I answered your query.

Hi Gulzar

If using regular expression, create a "Question Regular Expressions" ("Service Catalog" > "Catalog Variables" > "Variable Validation Regex"

I don't think regular expression alone will be able to fully validate all e164 numbers because the standard just have maximum number of digits. In actual usage, number of digits is defined by the country code.
