Loading files using JQuery

You never have to use standard JavaScript to load files, but it's good to know how it works. It's much, much simpler to load files using the JQuery library (Examples/example-10-ajax-jquery.html):

$.ajax({
     url: 'Data/sample.csv',
     success: function(text){
         parse(text)
     }
 });

You can also load and parse JSON files in a single step using JQuery:

$.getJSON('/Data/sample.json', function(object) {
     // use the JavaScript object
 }
