I sea a javascript funtion to validate emails... I need it to pass when the email field is empty

The function always returns false when the email is empty... I guess a change has to be done at the validation function level. The function is:

function validateEmail(fieldValue) {
     return (/^[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$/).test(fieldValue);
}

It returns false if the emailis empty... cant figure out why!!!

Try this code

 function validateEmail(fieldValue) {
      if (fieldValue!=null && fieldValue.length > 0)
      {
      
     return (/^[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$/).test(fieldValue);
       }
       return true;
}

You can check for null and for undefined. It's only an extension of the code from melchkishore :-)

manuel
function validateEmail(fieldValue) {
      if ((fieldValue != null || typeof(fieldValue) == "undefined") && fieldValue.length > 0)
      {
      
     return (/^[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$/).test(fieldValue);
       }
       return true;
}

Notice that you post this in the "new to java" zone. This is a JavaScript question and should really be posted in the zone with the same name. JavaScript != Java.
