- // The fileupload widget listens for change events on file input fields
- // defined via fileInput setting and drop events of the given dropZone.
- // In addition to the default jQuery Widget methods, the fileupload widget
- // exposes the "add" and "send" methods, to add or directly send files
- // using the fileupload API.
- // By default, files added via file input selection, drag & drop or
- // "add" method are uploaded immediately, but it is possible to override
- // the "add" callback option to queue file uploads.
- $.widget('blueimp.fileupload', {
-
- options: {
- // The namespace used for event handler binding on the dropZone and
- // fileInput collections.
- // If not set, the name of the widget ("fileupload") is used.
- namespace: undefined,
- // The drop target collection, by the default the complete document.
- // Set to null or an empty collection to disable drag & drop support:
- dropZone: $(document),
- // The file input field collection, that is listened for change events.
- // If undefined, it is set to the file input fields inside
- // of the widget element on plugin initialization.
- // Set to null or an empty collection to disable the change listener.
- fileInput: undefined,
- // By default, the file input field is replaced with a clone after
- // each input field change event. This is required for iframe transport
- // queues and allows change events to be fired for the same file
- // selection, but can be disabled by setting the following option to false:
- replaceFileInput: true,
- // The parameter name for the file form data (the request argument name).
- // If undefined or empty, the name property of the file input field is
- // used, or "files[]" if the file input name property is also empty:
- paramName: undefined,
- // By default, each file of a selection is uploaded using an individual
- // request for XHR type uploads. Set to false to upload file
- // selections in one request each:
- singleFileUploads: true,
- // Set the following option to true to issue all file upload requests
- // in a sequential order:
- sequentialUploads: false,
- // Set the following option to true to force iframe transport uploads:
- forceIframeTransport: false,
- // By default, XHR file uploads are sent as multipart/form-data.
- // The iframe transport is always using multipart/form-data.
- // Set to false to enable non-multipart XHR uploads:
- multipart: true,
- // To upload large files in smaller chunks, set the following option
- // to a preferred maximum chunk size. If set to 0, null or undefined,
- // or the browser does not support the required Blob API, files will
- // be uploaded as a whole.
- maxChunkSize: undefined,
- // When a non-multipart upload or a chunked multipart upload has been
- // aborted, this option can be used to resume the upload by setting
- // it to the size of the already uploaded bytes. This option is most
- // useful when modifying the options object inside of the "add" or
- // "send" callbacks, as the options are cloned for each file upload.
- uploadedBytes: undefined,
- // By default, failed (abort or error) file uploads are removed from the
- // global progress calculation. Set the following option to false to
- // prevent recalculating the global progress data:
- recalculateProgress: true,
-
- // Additional form data to be sent along with the file uploads can be set
- // using this option, which accepts an array of objects with name and
- // value properties, a function returning such an array, a FormData
- // object (for XHR file uploads), or a simple object.
- // The form of the first fileInput is given as parameter to the function:
- formData: function (form) {
- return form.serializeArray();
- },
-
- // The add callback is invoked as soon as files are added to the fileupload
- // widget (via file input selection, drag & drop or add API call).
- // If the singleFileUploads option is enabled, this callback will be
- // called once for each file in the selection for XHR file uplaods, else
- // once for each file selection.
- // The upload starts when the submit method is invoked on the data parameter.
- // The data object contains a files property holding the added files
- // and allows to override plugin options as well as define ajax settings.
- // Listeners for this callback can also be bound the following way:
- // .bind('fileuploadadd', func);
- // data.submit() returns a Promise object and allows to attach additional
- // handlers using jQuery's Deferred callbacks:
- // data.submit().done(func).fail(func).always(func);
- add: function (e, data) {
- data.submit();
- },
-
- // Other callbacks:
- // Callback for the start of each file upload request:
- // send: function (e, data) {}, // .bind('fileuploadsend', func);
- // Callback for successful uploads:
- // done: function (e, data) {}, // .bind('fileuploaddone', func);
- // Callback for failed (abort or error) uploads:
- // fail: function (e, data) {}, // .bind('fileuploadfail', func);
- // Callback for completed (success, abort or error) requests:
- // always: function (e, data) {}, // .bind('fileuploadalways', func);
- // Callback for upload progress events:
- // progress: function (e, data) {}, // .bind('fileuploadprogress', func);
- // Callback for global upload progress events:
- // progressall: function (e, data) {}, // .bind('fileuploadprogressall', func);
- // Callback for uploads start, equivalent to the global ajaxStart event:
- // start: function (e) {}, // .bind('fileuploadstart', func);
- // Callback for uploads stop, equivalent to the global ajaxStop event:
- // stop: function (e) {}, // .bind('fileuploadstop', func);
- // Callback for change events of the fileInput collection:
- // change: function (e, data) {}, // .bind('fileuploadchange', func);
- // Callback for drop events of the dropZone collection:
- // drop: function (e, data) {}, // .bind('fileuploaddrop', func);

- // dragover: function (e) {}, // .bind('fileuploaddragover', func);
