title: Can this jQuery/AJAX code be shortened?
body: <p>I have the following code which sets input values using jQuery/AJAX. Can the repetition of the code be shortened in anyway? It's mainly the AJAX requests I'd like shortened. It doesn't seem right to be making so many AJAX requests but despite my research I can't seem to find a way to improve things.</p>
