Execute Code When The URL Has Hash OR HASH Changes After Load?

Question

Any assistance would be greatly appreciated!

Execute code when a hash exists on load:

if(location.hash) { //code; }

Execute code when the hash changes:

$(window).hashchange(function(){//code;});

How do I combine these 2 checks?
This doesn't work:

if(location.hash || $(window).hashchange(function() { //code; });

Answer 1

Define a function for theCode, Pass its reference to hashchange event and on page load check if hash exists execute it directly

function theCode() { //code; }

if(location.hash){
    theCode();
}

$(window).hashchange(theCode);
