It's not valid to put JS function calls inside a string for use as a selector.
What you can do is select all inputs and then use the .filter() method to reduce the set to only those with a blank value:
$('input').filter(function() {
return this.value === '';
}).css('border','1px solid red');<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input value="Pineapple"> <input value=""> <input value="Orange">
<input value=""> <input value="Mango"> <input value="Lime">You may want to use return $.trim(this.value) === '' if fields with space characters in them count as empty for your purposes.
