Having trouble parsing A url object how I would like, still new to url strings would love some help. My object looks like this : 

{mod1: "/hello/world", mod25: "/hey/jude/how/are/you"}

and I need to parse it into something like this 

{
"mod1" : {"hello" : ["world"]},
"mod2" : {"hey" : ["jude","how","are","you"]}
}

How do I parse this url into an object like so? Thanks!

Edit: so far 

  var parseObj = $location.search();

            _.each(parseObj, function(ob){
                console.log(ob.split());
            });

This gives me back the strings, however i am not sure how to now split them into an object where the key is the first item

    so loop through the object and use split() Commented Mar 10, 2015 at 15:37
  • @dystroy stuck after the .split, unsure how to cut up the string into an object. Thanks! Commented Mar 10, 2015 at 15:43

Simple commented steps for you in vanilla JS:

// pass in the object to the function
function organise(obj) {

    // create a new object which we will return from the function
    var obj2 = {};

    // loop over the object we passed in
    for (var p in obj) {

        // create a temporary object
        var tmp = {};

        // split the value of current key/value pair into an array
        var arr = obj[p].split('/');

        // set the key of the temporary object to the second element
        // (because the first element of the array is an empty string)
        var key = arr[1];

        // add the rest of the array as the value of the new key
        // of the temporary object
        tmp[key] = arr.slice(2);

        // finally add the new temporary object as the value of the key
        // of the object we want to return
        obj2[p] = tmp;
    }

    // return the object from the function
    return obj2;
}

organise(obj);

How about this one?

var x = {mod1: "/hello/world", mod25: "/hey/jude/how/are/you"};

var result = {};

for(var i in x) {
  var entries = x[i].split('/');
  var firstEntry = entries[1];
  var arr = [];
  for(var j = 2; j < entries.length; j++) {
    arr.push(entries[j]);
  }
  var obj = {}
  obj[firstEntry] = arr;
  result[i] = obj;
}

console.log(result);

Loop over the object properties, split the values and insert them into a second object.

function parse(obj) {
  var out = {},
    parts;
  for (prop in obj) {
    if (obj.hasOwnProperty(prop)) {
      out[prop] = {};
      // replace the first forward slash with nothing so the first 
      // element of the array is not an empty string.
      parts = obj[prop].replace('/', '').split('/');
      // make the first element of the array the key and assign the 
      // rest of the array as the value.
      out[prop][parts.shift()] = parts;
    }
  }
  return out;
}

var obj = parse({
  mod1: "/hello/world",
  mod25: "/hey/jude/how/are/you"
});
// just display the object
document.write('<pre>' + JSON.stringify(obj, 0, 3));
