Validate 4th letter of a word using jqueryvalidation

Question

I am using http://jqueryvalidation.org/. And I want to add a rule to validate the field from the value entered by users on fourth letter.

Like if value is = ABCPUJJE

and we set rule that fourth letter = P

then the rule will check fourth value and display message "Right value entered" else "Please Enter correct value"

You should have made an honest attempt at this yourself before asking for help. — Sparky, Mar 14 '14 at 20:34

Defining custom method

function myTextOnlyValidation(value, element){

   var fourthChar = value.charAt(3);

   if (fourthChar === 'P') {
     return true;
   } else {
     return false;
   }
}

Add custom method to jquery validator

jQuery.validator.addMethod("validateChar", myTextOnlyValidation, "Custom Message");

Adding validation to the element

$('#TestForm').validate({
  rules : {
     txtboxElement: { validateChar: true }
  }
});
