Note: There are BC Breaking Changes with release v2.4.0.

With release v2.4.0, the plugin has been revamped to support and configure a wide variety of file formats for preview. This may break some backward compatibility (BC) for older versions that use custom templates.

The following are the major changes with release v2.4.0:

Plugin has been revamped to build preview intelligence based on various file preview types. The inbuilt file support types are categorized as image, text, html, video, audio, flash, object, and other.
allowedPreviewTypes: You can now configure which all file types are allowed to be shown as a preview. This defaults to ['image', 'html', 'text', 'video', 'audio', 'flash', 'object']. Thus all file types are treated as an object to preview by default. For exampleTo preview only image and video, you can set this to ['image', 'video'].
allowedPreviewMimeTypes: In addition to allowedPreviewTypes, you can also control which all mime types can be displayed for preview. This defaults to null, meaning all mime types are supported.
layoutTemplates: Allows you to configure all layout template settings within one property. The layout objects that can be configured are: main1, main2, preview, caption, and modal.
previewTemplates: All preview templates for each preview type have been combined into one property, instead of separate templates for image, text etc. The keys are the formats as set in allowedPreviewTypes and values are the templates used for previewing. There are default prebuilt templates for each preview file type (generic, image, text, html, video, audio, flash, object, and other). The generic template is used only for displaying initialPreview content using direct markup.
previewSettings: Allows you to configure width and height for each preview image type. The plugin has default widths and heights predefined for each type i.e image, text, html, video, audio, flash, and object.
fileTypeSettings: Allows you to configure and identify each preview file type using a callback. The plugin has default callbacks predefined to identify each type i.e image, text, html, video, audio, flash, and object.
Replacing tags within templates has been enhanced. With this release it will automatically check for multiple occurrences of each tag to replace within a template string.

NOTE: Flash preview will require Shockwave flash to be installed and supported by the client browser. The flash preview currently works successfully with webkit browsers only. Video & Audio formats are however supported by all modern browsers that support the HTML5 video/audio tags. Note that browsers have limited number of video/audio formats supported by the HTML5 video element (e.g. mp4, webm, ogg, mp3, wav). The size of video files are recommended to be small (to be controlled through maxFileSize property) so that it does not affect the preview performance. You can copy a few files from the examples directory of this plugin repo, to test a few examples of flash and video files.

Date: 19-Sep-2014

Better replacement of tags in templates. Replaces all tag occurences with this new release.

This is by default set to true, whereby, any initialPreview content set will be overwritten, when new file is uploaded or when files are cleared. Setting it to false will help displaying a saved image or file from database always - useful especially when using the multiple file upload feature.

version 1.6.0

Date: 03-Jun-2014

The plugin now offers an additional refresh method. This enables you to dynamically change element attributes or plugin options at runtime and refresh the widget.

version 1.5.0

Date: 23-May-2014

The plugin now offers an option to display initial preview of images/text/other files. This is useful for record update scenarios. This can be a single image/file or an array of images/files.
Extending to the above feature, the plugin also allows you to set a preview caption for the initial preview field.
The following element identifiers need to be passed as a string like '#id' instead of a JQuery object:
- elCaptionContainer
- elCaptionText
- elPreviewContainer
- elPreviewImage
- elPreviewStatus

version 1.0.0

Date: 01-Jan-2014

Initial release. The following features are included in this release:

The plugin will convert a simple HTML file input to an advanced file picker control. Will help fallback to a file input for browsers not supporting JQuery or Javascript.
The file input consists of the following three sections with options and templates to control the display:
- file caption section: to display a brief information of the file(s) selected
- file action buttons section: to browse, remove, and upload files.
- file preview section: to display the selected files on client for preview (supports images and text file types). Other file types will be displayed as normal thumbnails.
The plugin automatically converts an input with type = file to an advanced file picker input if you set its class = file. All options to the input can be passed as HTML5 data attributes.
Ability to select and preview multiple files. Uses HTML 5 File reader API to read and preview files. Displays the progress of files being being loaded onto the preview zone, in case many files are chosen.
Offers predefined templates and CSS classes which can be changed to style your file-input display as per your needs.
Option to show/hide any or all of the following:
- caption section
- preview section
- upload button
- remove button
Customise the location of the target container elements to display the entire plugin, the caption container, the caption text, the preview container, preview image, and preview status.
For text file previews, autowrap the text to the thumbnail width, and show a wrap indicator link to display complete text on hover. You can customize the wrap indicator (which defaults to …).
Customise the messages for preview, progress, and files selected.
Upload action defaults to form submit. Supports an upload route/server action parameter for custom ajax based upload.
Triggers JQuery events for advanced development. Events currently available are filereset and fileclear.
Disabled and readonly file input support.
Size of the entire plugin is less than 11KB (about 9KB for the minified JS and 2KB for the minified CSS).
