How do you limit a variable to 10digits?

[Navneet3]

Hi, The requirement is> minimum of 10 digits is required for a variable.

Is this the correct script?

Here is the script. I created a on change script.

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

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

return;

}

 var val = g_form.getValue('Facility_npi');

var pattern = /\d{10}/;

if (pattern.test(val))

alert('looks like 10 digits');

else

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

    var num = g_form.getValue('number'); // add number field value
    var pattern = /^[0-9]{10}$/;

    if (pattern.test(num)) {
        g_form.setValue('number', num);
    } else {
        alert("Please make sure that the number you provide is 10 digits long");

Hi Navneet,

                     If my response with output is worked for you, mark it as correct, so it will be useful for future readers

Since you have already used Validation regex as number all you need is a check for length.

Try below

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var val = g_form.getValue('Facility_npi');
    var lengthis = val.length;
    if (lengthis > 9) { //do nothing
    } else {
        alert('Enter more than 10 digits');
        g_form.getValue('Facility_npi', '');
    }

}
