ServiceNow Learning 26: Common and frequently used RegExp expressions which can be use in ServiceNow

[Shamma Negi]

Hi All,

Common and most frequently used RegExp in ServiceNow

1. Password or any string field length should not be less than 8 digits (This one is without usage of RegExp but useful one).

process : function() {
          var user_password = request.getParameter("user_password");
          var min_len = 8;
          var rules = "Password must be at least " + min_len + 
             " characters long and contain a digit, an uppercase letter, and a lowercase letter.";
          if (user_password.length() < min_len) {
             gs.addErrorMessage("TOO SHORT: " + rules);
             return false;
          }

2. Password or strong field should contain number/digits (0-9)

var rules = "Password must be at least " + min_len + 
             " characters long and contain a digit, an uppercase letter, and a lowercase letter."

var digit_pattern = new RegExp("[0-9]", "g");
          if (!digit_pattern.test(user_password)) {
             gs.addErrorMessage("DIGIT MISSING: " + rules);
             return false;
          }

3. It should contain uppercase letters 

 var upper_pattern = new RegExp("[A-Z]", "g");
          if (!upper_pattern.test(user_password)) {
             gs.addErrorMessage("UPPERCASE MISSING: " + rules);
             return false;
          }

4. It should contain lowercase letters

var lower_pattern = new RegExp("[a-z]", "g");
          if (!lower_pattern.test(user_password)) {
             gs.addErrorMessage("LOWERCASE MISSING: " + rules);
             return false;
          }

Hope this helps.
