Refactoring duplicated jQuery script, Inputs focus .show() or .hide() div for multiple inputs and hidden divs












0












$begingroup$


I posted a question on StackOverflow and got an answer that works but has a lot of duplicated code. In the future, the functionality may also require a third or more divs to be shown or hidden.



The original script also came from a SO answer.



Can this code be refactored or improved to accommodate more than 2 inputs and hidden divs?



When the client focuses in a text field the associated div is shown or hidden on blur.

      I posted a question on StackOverflow and got an answer that works but has a lot of duplicated code. In the future, the functionality may also require a third or more divs to be shown or hidden.



      The original script also came from a SO answer.



      Can this code be refactored or improved to accommodate more than 2 inputs and hidden divs?



      When the client focuses in a text field the associated div is shown or hidden on blur.

          Is this a new Fibonacci Identity?

          Image
          6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
