Sorry, but this.value != "" isn't a good validation (see here on page 18).

You better use

this.rawValue !== null;

or the built-in method isNull() to check a fields value against null.

this.isNull();

You can make your filed mandatory to avoid JS. 

Or

You can write your validation script under "Validate" expression. 

If you are using rule editor its quite simple. 

One sample validation is - 

this.value !==null   or this.isNull() for blank fields. Just write this script in validate expression.
