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.
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. With release 4. Most modern browsers do support this standard, but the plugin will automatically degrade to normal form based submission for unsupported browsers.
Will degrade to normal Form Based File submission if this is not supported. Thus one can append files to preview. If showPreview is set to false, or uploadUrl is not supported plugin will degrade to normal form based upload.
Configurable indicators for file awaiting upload, file successfully uploaded, files errored in upload. Build up initial preview content e. You can set initial preview actions prebuilt support for initial preview delete. Other custom action buttons can be set for initial preview thumbnails as well. The bootstrap-fileinput plugin can be installed automatically or manually using one of these options:.
You can also manually install the plugin easily to your project. If you noticed, you need to load the jquery. For enabling the default icons used in the plugin load the Bootstrap 5. The locale file for your language LANG. The piexif. It is required to be loaded before fileinput. This library is also needed for restoring the exif data to the image files when using the image resize feature of the bootstrap-fileinput plugin.
The sortable. Initialize the plugin on your page. For example to initialize using javascript - the following code can be placed in document. The input-id is the identifier for the input e. Alternatively, you can directly set the plugin options to any input, through HTML 5 data attributes to your input field. Note that for this case, you need to attach the CSS class file to the input. However, the plugin can be customized for any CSS framework using templates. For details, refer the browser support section.
For Internet Explorer, one must use IE versions 10 and above. The plugin will automatically degrade to normal form based submission for browsers not supporting AJAX uploads. The plugin uses HTML 5 features to achieve various functionalities.
Most modern browsers support these features. However, to know if your browser supports these functions you must run through these checks once below. Largely speaking, the plugin can be configured in one of the following two different modes for upload.
In this mode, you do not set the uploadUrl property. This is useful for single file uploads OR simpler scenarios of multiple file uploads. However, note that the native file input is read only and cannot be modified or updated by external code. Especially for multiple file input selections, ONE cannot append files to an already selected file list. If one tries to select files on an already selected file input, it will overwrite and clear the previous selection.
If the uploadUrl is set, then the plugin automatically assumes an ajax upload for the scenario. The plugin offers advanced features for ajax submission that is not available in form submission.
However for form based uploads it is restricted to browsers like Chrome and Mozilla that support assigning FileList object to the native file input. As shown in the usage section, translations are now enabled with release 4. Follow these steps to enable translations for your language:. This script must be loaded after the core fileinput. If your locale file does not exist, you can create the translations for the new language by submitting a github pull request to add to this folder.
Check the sample locale file to copy and create a translation configuration for your own language. You need to setup the server methods to parse and return the right response via AJAX. You can setup uploads in asynchronous OR synchronous modes as described below. This is the default mode , whereby the uploadAsync property is set to true.
When uploading multiple files, the asynchronous mode allows triggering parallel server calls for each file upload. You can control the maximum number of files allowed at a time to be uploaded by setting the maxFileCount property. In asynchronous mode, progress of each thumbnail in the preview is validated and updated. Your server method as set in uploadUrl receives the following data from the plugin. Note that multiple file uploads require that you set multiple property to true for your input.
This can be done by setting uploadExtraData as an associative array object in key value pairs. Your server method as set in uploadUrl must send data back as a json encoded object. For example, the server could return a JSON object like below:. The JSON object that you return from the server consists of 5 pieces of information. Note: The plugin will automatically validate and display ajax exception errors. You will always send ONE row in this array - because you will always receive ONE file with the upload in asynchronous mode.
If this property is set, the plugin will automatically replace the files dynamically in the preview content after upload success. The configuration for this is similar to the initialPreview option setting.
For example:. The configuration for this is similar to the initialPreviewConfig option setting. The initial preview thumbnails set via initialPreview will read this configuration for replacing tags.
If not set this defaults to true. If set to false , the plugin will overwrite the initialPreview content.
This is to be setup as mentioned above. You can also send in additional keys or data with your JSON response, for you to process them for advanced cases using events like fileuploaded. In this mode, the uploadAsync property is set to false. This will trigger just one batch upload call to the server and send files from client to server as an array object.
Even in this mode, you can control the maximum number of files allowed at a time to be uploaded by setting the maxFileCount property. In this article, we will learn how to download files using JavaScript. Automatic downloading files help us retrieve files directly from the URL with a JavaScript function without contacting any servers. We will achieve this using our custom written functions and using the download attribute of HTML 5. The download attribute in HTML 5 is used to download files when users click on the hyperlink.
We are required to set the href attribute specifying the source of the file. The value of the download attribute determines the name of the downloaded file. If this value is removed, then the downloaded filename will be the same as the original file name.
In the above code, we download an image apple.
