JS - set and get hash query values from a URLs

js-hash-url.js

// get the HASH values
function getHashParams() {

    var hashParams = {};
    var e,
        a = /\+/g,  // Regex for replacing addition symbol with a space
        r = /([^&;=]+)=?([^&;]*)/g,
        d = function (s) { return decodeURIComponent(s.replace(a, ' ')); },
        q = window.location.hash.substring(1);

    while (e = r.exec(q))
       hashParams[d(e[1])] = d(e[2]);

    return hashParams;
}


// example.com/page/#showme=8&offset=10&hidden=true

// get a value from hash
getHashParams().showme == '8'

// set the hash
document.location.hash = 'showme='+wtv+'&offset='+wtv+'&hidden='+wtv;
