// This [jQuery](https://jquery.com/) plugin implements an `<iframe>`
// [transport](https://api.jquery.com/jQuery.ajax/#extending-ajax) so that
// `$.ajax()` calls support the uploading of files using standard HTML file
// input fields. This is done by switching the exchange from `XMLHttpRequest`
// to a hidden `iframe` element containing a form that is submitted.

// The [source for the plugin](https://github.com/cmlenz/jquery-iframe-transport)
// is available on [Github](https://github.com/) and licensed under the [MIT
// license](https://github.com/cmlenz/jquery-iframe-transport/blob/master/LICENSE).

// ## Usage

// To use this plugin, you simply add an `iframe` option with the value `true`
// to the Ajax settings an `$.ajax()` call, and specify the file fields to
// include in the submssion using the `files` option, which can be a selector,
// jQuery object, or a list of DOM elements containing one or more
// `<input type="file">` elements:

//     $("#myform").submit(function() {
//         $.ajax(this.action, {
//             files: $(":file", this),
//             iframe: true
//         }).complete(function(data) {
//             console.log(data);
//         });
//     });

// The plugin will construct hidden `<iframe>` and `<form>` elements, add the
// file field(s) to that form, submit the form, and process the response.

// If you want to include other form fields in the form submission, include
// them in the `data` option, and set the `processData` option to `false`:

//     $("#myform").submit(function() {
//         $.ajax(this.action, {
//             data: $(":text", this).serializeArray(),
//             files: $(":file", this),
//             iframe: true,
//             processData: false
//         }).complete(function(data) {
//             console.log(data);
//         });
//     });

// ### Response Data Types

// As the transport does not have access to the HTTP headers of the server
// response, it is not as simple to make use of the automatic content type
// detection provided by jQuery as with regular XHR. If you can't set the
// expected response data type (for example because it may vary depending on
// the outcome of processing by the server), you will need to employ a
// workaround on the server side: Send back an HTML document containing just a
// `<textarea>` element with a `data-type` attribute that specifies the MIME
// type, and put the actual payload in the textarea:

//     <textarea data-type="application/json">
//       {"ok": true, "message": "Thanks so much"}
//     </textarea>

// The iframe transport plugin will detect this and pass the value of the
