Regex for Digit and Dashes (Phone number)

[BuriB]

Hi All, 

we will restrict phone regex 

We will allow digits with dashes in between, but the dashes could be optional. 

Example: 555555555 or 555-555-555 (no leading zero)

Currently we have the following regex: 

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var regex = /^[1-9][0-9]{0,29}$/; // regex for phone numbers

How can we solve this? Could you please help

Hi @BuriB,

I've tweaked it slightly and tested it to ensure it works as required:

(Please note, the 4 highlighted in bold in the ending brackets it the number used to determine the minimum and maximum number. So in using the regex as shown below you can have 9 minimum (3+3+3) and 10 maximum (3+3+4). If you want to extending this to 11 numbers for example, change the 4 to a 5.)

/^[1-9]{3}(-)?\d{3}(-)?\d{3,4}$/gm;

Hi @BuriB,

(Updated since original post @BuriB )

The regex required to match either '123123123' or '123-123-123' with no leading zero and no spaces is:

/^\d{3}(-)?\d{3}(-)?\d{3}$

hi Robbie, 

its not working as expected. It allows leading zero and is restricted to 9 digits in total but the number could more than 9 digits
