Hi Rajashekar,

The below script will do the required checks.

var test_string = "1234";// replace with your form variable

var regex = /^[\+\-()0-9]{0,10}$/;

var result = regex.test(test_string);

alert(result);

Also make use of madrid  Variable Validation Regex.

For more details on using Variable Validation Regex check the below link.

Hi,

Please try this code for above Requirement.It's Working fine on my DEV.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var phone = g_form.getValue('phone_number');// Phone_number is my variable name
var answer = true;
var param =/^[0-9-+()]{1,15}$/;
if (!phone.match(param))

{

g_form.addErrorMessage('Only valid Phone numbers are allowed');
g_form.clearValue('phone_number');
answer = false;
}
else if (phone == /^[0-9-+()]{1,15}$/)
{
g_form.setValue('phone_number');

} else {
answer = true;
}
return answer;
}

Thanks,

Prathyusha.
