Question

so lets say i have a url http://www.hello.com#one

i know i can grab the has value

var hash = window.location.hash;
alert (hash);

but rather then write (i know the below is not propper code):

if var hash = one then set var hashValue to 1

else

if var hash = two then set var hashValue to 2

else etc etc

is there a better way to write this.

Cheers

Answer 1

var map = {
  one: 1,
  two: 2
};

var hashValue = map[hash.substring(1)];

This will set hashValue to undefined if hash doesn’t exist in the map.
