Find most used values in JSON file with Javascript

var countries = {};

for (i = 0; i < postObject.mediaPosts.length;
i++) {
    var country =
    countries[country] = countries[country] ?
countries[country] + 1 : 1

then you will have an object (an associative array) of the countries as keys, and their count in the input object. Something like this:

countries = {
    "Afghanistan" : 5,
    "Albania" : 3,
    "Bulgaria" : 2,
    //... the other countries

From there you can loop over it and create pairs from it

var countryCountPairs = {};

for (country in countries) {
    countryCountPairs.push({country : country, 
count : countries[country]});

Which will get you a data structure like this:

countryCountPairs = {
    { country : "Afghanistan",  count : 5 },
    { country : "Albania",  count : 3 },
    { country : "Bulgaria",  count : 2 },
    //... the other countries

And that is easily sortable:

countryCountPairs.sort(function(a, b) {
    // I think biggest value comes first with
this, but you will have to test it. 
    return b.count - a.count;  

Which will give you a sorted version of the above.

Referring to i values in Javascript for loops
You can use for (var i=1; i<3; i++) { var top = Math.random()*450 - 150, left = Math.random()*1150, el = document.getElementById("image" + i); = top + "px"; = left + "px";"block"; } Simply, at each iteration you will override the values of the previous iteration.

Displaying key and values of the options in a dropdown using javascript
What you're trying to do is impossible (with a native <select>). The item you see in the closed <select> is simply the <option> that is currently selected. When you open the drop-down, you see the same <option> in two places - in the "selection" and in the "list". You cannot see a different value in each of the places, when it's the same <option>. You could, however,

Move values from JSON to javascript array
If I understand you, you're trying to replace the data part of the JS object that you're passing to the Morris Bar function? You need to create an array not an object. Try something like this: var USD = data.d.results[0].ExchangeCross; var USD2 = data.d.results[0].ApprovedRate; var dataArray = []; // push each item into the array dataArray.push( {year: USD, value: USD2} ); Morris.Bar({ e
