Hi ,

Thanks

Hi @raj99918,

This is ServiceNow's prescribed implementation:

You may however want to play or adjust the regex for your need. Eg:  ^\+[1-9]{1}[0-9]{1,14}$

1. Create a variable of Single Line Text type.
2. Create the following onChange client script:
   • Type: onChange
   • Variable name: the name of the variable to be use
   • Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    //Type appropriate comment here, and begin script below
    var pattern = /^[(]?(\d{3})[)]?[-|\s]?(\d{3})[-|\s]?(\d{4})$/;

    if (!pattern.test(newValue)) {
        alert('Phone enter a valid phone number');
        g_form.setValue('variable_name', '');
    }
}

*Please note that the above regex / pattern is specific for validating 10 integer digits only. You may modify this regex if there's a need for it to validate any other formats.

Hi @raj99918,

Is there any sort of pattern to the number you wish to apply? 

For a general regex that literally just allows numbers and the '-' and '+' symbols, use the following regex:

/^[0-9+-]*$

Hi @raj99918 ,

you can use the regex as below in your code,

^\+?\d{1,3}-?\d{3}-?\d{3}-?\d{4}$

which checks for all below possibilities

+123-456-7890, 123-456-7890, +1-123-456-7890, 1234567890, etc.
