javascript - Alternative to many if / else statements in JS / JQuery? -

i trying compare many page elements initial values changed user, prompt them save etc.

is there better way check without many if / else statements? switch doesn't work since there many different values being check, instead of single 1 many cases. , tips / pointers welcome, thanks!

iterate elements, compare each one, , if there changes, prompt user save:

var save = false;  $('[id^="initial"]').each(function() {     if ( this.value != $('#'+this.id.replace('initial','')).val()) save = true; });  if (save) confirm(' save '); 

normally you'd solve different way, changing variable when element changed, , not check of elements @ time:

var save = false;  $(':input').on('change', function() {     save = true; });  window.onbeforeunload = function() {     if (save) confirm(' save '); }
