Example
The code sample below demonstrates how you can perform a custom validation without using any predefined validation capabilities. Note that in this case, the ValidationSettings.EnableCustomValidation property should be set to true to show an error frame.
function OnAgeValidation(s, e) {
var age = tbAge.GetText();
if (age == null || age == "")
return;
var digits = "0123456789";
for (var i = 0; i < age.length; i++) {
if (digits.indexOf(age.charAt(i)) == -1) {
tbAge.SetIsValid(false);
break;
}
}
if (tbAge.GetIsValid() && age.charAt(0) == '0') {
age = age.replace(/^0+/, "");
if (age.length == 0)
age = "0";
tbAge.SetText(age);
}
if (age < 18) {
tbAge.SetIsValid(false);
tbAge.SetErrorText('Age must be greater than or equal 18');
}
}
