javascript random string to put on url for cache

I was having a bit of a cache issue with a external css file, so i thought i might fix this by appending a random query string to the file name. This should force the browser to recheck the file each load time rather than caching it as it will think its a new file name. 

There are a few options in javascript that can achieve this. 

Note: This one is not solved yet, got distracted... ;)

Scripts

<!-- <link rel="stylesheet" href="theme.css" /> -->

Javascript

/* you could append a new date string to json */
var random_string = (new Date).toJSON();
console.log(random_string);

/* you could then md5 that if you want something more cryptic */
/* var random_string_2 = crypto.createHash('md5').update((new Date).toJSON());
console.log(random_string_2); */
/* actually that one does not work, (not sure what the crypto js library is... )*/
