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?"); * }); */ // Cut down on the number if issues from people inadvertently including jquery_ujs twice // by detecting and raising an error when it happens. var alreadyInitialized = function() { var events = $._data(document, 'events'); return events && events.click && $.grep(events.click, function(e) { return e.namespace === 'rails'; }).length; } if ( alreadyInitialized() ) { $.error('jquery-ujs has already been loaded!'); } // Shorthand to make it a little easier to call public rails functions from within rails.js var rails; $.rails = rails = { // Link elements bound by jquery-ujs linkClickSelector: 'a[data-confirm], a[data-method], a[data-remote], a[data-disable-with]', // Select elements bound by jquery-ujs inputChangeSelector: 'select[data-remote], input[data-remote], textarea[data-remote]', // Form elements bound by jquery-ujs formSubmitSelector: 'form', // Form input elements bound by jquery-ujs formInputClickSelector: 'form input[type=submit], form input[type=image], form button[type=submit], form button:not([type])', // Form input elements disabled during form submission disableSelector: 'input[data-disable-with], button[data-disable-with], textarea[data-disable-with]', // Form input elements re-enabled after form submission enableSelector: 'input[data-disable-with]:disabled, button[data-disable-with]:disabled, textarea[data-disable-with]:disabled', // Form required input elements requiredInputSelector: 'input[name][required]:not([disabled]),textarea[name][required]:not([disabled])', // Form file input elements fileInputSelector: 'input:file', // Link onClick disable selector with possible reenable after remote submission linkDisableSelector: 'a[data-disable-with]', // Make sure that every Ajax request sends the CSRF token CSRFProtection: function(xhr) { var token = $('meta[name="csrf-token"]').attr('content'); if (token) xhr.setRequestHeader('X-CSRF-Token', token); }, // Triggers an event on an element and returns false if the event result is false fire: function(obj, name, data) { var event = $.Event(name); obj.trigger(event, data); return event.result !== false; }, // Default confirm dialog, may be overridden with custom confirm dialog in $.rails.confirm confirm: function(message) { return confirm(message); }, // Default ajax function, may be overridden with custom function in $.rails.ajax ajax: function(options) { return $.ajax(options); }, // Default way to get an element's href.
