I want to add something to existing answers to clear the behavior of $(selector).each and why it doesn't respect return false in OP's code.

return keyword inside $(selector).each is used to break or continue the loop. If you use return false, it is equivalent to a break statement inside a for/while loop. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration. Source

Because you're returning false, the loop breaks and the function ends up returning undefined in your case. Your option is to use a var outside $.each or avoid using it altogether as @TJCrowder wrote.
