Phone number validation

[User_267]

In catalog form. There is a field call phone number.

User has to enter phone number in that field. And the phone number format is 123-456-7890.

If user doesn't enter in any above format. It shows error.

If user enters in above format . It needs to populate as (123)456-7890.

Require client script for this.

Hi @User_267 ,

1. Create the following onChange client script:

• • Type: onChange
  • Variable name: the name of the variable to be used
  • 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.

I have the above script, but if someone enters in correct format like 123-456-7890 then it should automatically populate as (123)456-7890 in this format in the field

Hi @User_267 

try to add this missing line in your script that will re format the number after entering 

 var formattedNumber = ‘(’ + match[1] + ‘)’ + match[2] + ‘-’ + match[3];
        // Update the field value with the formatted number.
        g_form.setValue(control.getName(), formattedNumber);
