Set a variable based on the #of a url -- window.location.hash

so lets say i have a url 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

You can also use switch block to do this.

switch(location.hash.replace('#', '')){
    case "one": newhash = 1;
    break;
    case "two": newhash = 2;
    break;    
};
alert (newhash);

Actually the hash returns the hash value including the # sign

So hash='#one' not 'one'. Apart from that you could use a switch case switch(hash) { case '#one': hashVar=1; case '#two': hashVar=2; }

if you are willing to change the hash style to say #tab1 #item1 or simply #1 instead of #one or something, u cud get the number pretty easily

var hash = window.location.hash;//hash=#tab1 say
var number=hash.replace('#tab',"");
alert(number);

That's it. this way, the number can be as large as you want. In the first case you'd have to manually assign the variable for each number

So if there were 100 items you'd have a pretty long list

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.
