Ajax Prefilter

Ajax prefilters are useful for hooking into all AJAX request. In this case, we want to send all our AJAX request off to a remote server instead of the same domain. So we use a prefilter to hook in before the request is sent and prepend our custom origin server.

$.ajaxPrefilter( function( options, originalOptions, jqXHR ) {
  options.url = 'http://backbone-beginner.herokuapp.com' + options.url;
});

jQuery SerializeObject

By default jQuery doesn't allow us to convert our forms into Javascript Objects, someone wrote this snippet on Stack Overflow that I have been using for years. Simply call it via $(form).serializeObject() and get a object returned.

$.fn.serializeObject = function() {
  var o = {};
  var a = this.serializeArray();
  $.each(a, function() {
      if (o[this.name] !== undefined) {
          if (!o[this.name].push) {
              o[this.name] = [o[this.name]];
          }
          o[this.name].push(this.value || '');
      } else {
          o[this.name] = this.value || '';
      }
  });
  return o;
};

Preventing XSS

As always you need to protect your users by encoding input and output, here is some simple methods for doing so.

function htmlEncode(value){
  return $('<div/>').text(value).html();
}

function htmlDecode(value){
  return $('<div/>').html(value).text();
}
