Email Validation script Required

[venkateshdhanap]

Hi All,

Need to validate on Email field with below condition (Wrote Onchange client script on Email part)

• uppercase and lowercase letters A to Z and a to z;
• digits 0 to 9 allowed at the end of local part
• Allows single quote( ' )
• Domain part must contains ( A-Z, 0-9, - )
• comments are allowed with parentheses at either end of the local-part; e.g. john.smith(comment)@example.com and (comment)john.smith@example.com are both equivalent to john.smith@example.com.
• special characters !#$%&'*+-/=?^_`{|}~;
• dot ., provided that it is not the first or last character unless quoted, and provided also that it does not appear consecutively unless quoted (e.g. John..Doe@example.com is not allowed but "John..Doe"@example.com is allowed);
• space and "(),:;<>@[\] characters are allowed with restrictions (they are only allowed inside a quoted string, as described in the paragraph below, and in addition, a backslash or double-quote must be preceded by a backslash);

Please provide the script for validate email with above conditions

Thanks in advance

Hello Venkatesh,

Try below script:

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

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

          return;

    }

  g_form.hideErrorBox('u_contact_email');

      var pattern =/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;   // regex pattern

  if(!pattern.test(newValue)){

    g_form.showErrorBox('u_contact_email', getMessage('Invalid Email ID'));//show error messege

          g_form.setValue(' u_contact_email', '');

Hello Venkatesh,

As I said you have to modify the regex as per your requirement. And you can test that in https://regex101.com/
