Quick and dirty deparam function for dealing with querystrings created via traditional.

deparam.js

var deparam = function(paramString) {
  var items = paramString.replace(/\+/g, ' ').split('&');
  var returnObj = {};
  
  _.each(items, function(params) {
    var param = params.split('=');
    returnObj[param[0]] = decodeURIComponent(param[1]);
    
    var array = returnObj[param[0]].split(',');
    if (array.length > 1) returnObj[param[0]] = array;
  });
  
  return returnObj;
}

console.log(deparam("currentPage=1&perPage=20&sort=lastmodified&sortOrder=desc&filterText=&filterAssignments=the-is-there-a-picture-assignment-even-longer-name%2Csb-assignment%2Cbook2&filterStatus=&filterType=poem&loading=true&_=1377264895003"));
