+/**
+ * Unobtrusive scripting adapter for jQuery
+ *
+ * Requires jQuery 1.6.0 or later.
+ * https://github.com/rails/jquery-ujs
+
+ * Uploading file using rails.js
+ * =============================
+ *
+ * By default, browsers do not allow files to be uploaded via AJAX. As a result, if there are any non-blank file fields
+ * in the remote form, this adapter aborts the AJAX submission and allows the form to submit through standard means.
+ *
+ * The `ajax:aborted:file` event allows you to bind your own handler to process the form submission however you wish.
+ *
+ * Ex:
+ * $('form').live('ajax:aborted:file', function(event, elements){
+ * // Implement own remote file-transfer handler here for non-blank file inputs passed in `elements`.
+ * // Returning false in this handler tells rails.js to disallow standard form submission
+ * return false;
+ * });
+ *
+ * The `ajax:aborted:file` event is fired when a file-type input is detected with a non-blank value.
+ *
+ * Third-party tools can use this hook to detect when an AJAX file upload is attempted, and then use
+ * techniques like the iframe method to upload the file instead.
+ *
+ * Required fields in rails.js
+ * ===========================
+ *
+ * If any blank required inputs (required="required") are detected in the remote form, the whole form submission
+ * is canceled. Note that this is unlike file inputs, which still allow standard (non-AJAX) form submission.
+ *
+ * The `ajax:aborted:required` event allows you to bind your own handler to inform the user of blank required inputs.
+ *
+ * !! Note that Opera does not fire the form's submit event if there are blank required inputs, so this event may never
+ * get fired in Opera. This event is what causes other browsers to exhibit the same submit-aborting behavior.
+ *
+ * Ex:
+ * $('form').live('ajax:aborted:required', function(event, elements){
+ * // Returning false in this handler tells rails.js to submit the form anyway.
+ * // The blank required inputs are passed to this function in `elements`.
+ * return ! confirm("Would you like to submit the form with missing info?");
+ * });
