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 @Robbie , 

we are very close now - when we can allow that we can enter Zero after the first digit and length can up to 30 digits in total, then we got it. 

Thank you

Hi @Robbie , 

@Amit Verma 

I got it = /^[1-9](-)?[0-9 \-]{0,29}$/;

Thank you all

Hi @BuriB , you can try the following regex: 

/^[1-9]\d{2}(-)?[1-9]\d{2}(-)?[1-9]\d{2}$/
