Getting started with JavaScript (ES5) FileManager control

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Component Initialization

Create an app folder myapp in local machine to initialize Essential JS 2 JavaScript components.

Using either of the following way to refer the required script and styles.

  • Using local script and style references in a HTML page.
  • Using CDN link for script and style reference.

Using local script and style references in a HTML page

Step 1: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Step 2: To render file manager component, need to add file manager and its dependent packages from below installed location.

Dependencies

  • ej2-base
  • ej2-layouts
  • ej2-popups
  • ej2-data
  • ej2-inputs
  • ej2-lists
  • ej2-buttons
  • ej2-splitbuttons
  • ej2-navigations
  • ej2-grids
  • ej2-filemanager

Syntax:

package: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}

Example:

Package: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\17.1.0.36\Web (Essential JS 2)\JavaScript\ej2-base

packages: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\17.1.0.36\Web (Essential JS 2)\JavaScript\ej2-inputs

Package: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\17.1.0.36\Web (Essential JS 2)\JavaScript\ej2-filemanager

Step 3: Create a folder myapp/resources and copy/paste the above mentioned packages from the above installed location to myapp/resources location.

Step 4: Create a HTML page (index.html) in myapp location and add the Essentials JS 2 script and style references.

       <body>
       </body>
  </html>

Note: If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

Step 5: Now, add the div element and initiate the Essential JS 2 File Manager component in the index.html by using following code

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
            <title>Essential JS 2 File Manager Component</title>
            <!-- File Manager and its dependent theme -->
            <link href=" resources/ej2-base/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-inputs/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-popups/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-buttons/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-splitbuttons/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-layouts/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-navigations/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-grids/styles/material.css" rel="stylesheet" />
            <link href=" resources/ej2-filemanager/styles/material.css" rel="stylesheet" />
            <!-- Essential JS 2 File-Manager's global script -->
            <script src="resources/ej2-base/dist/global/ej2-base.min.js" type="text/javascript"></script>
            <script src="resources/ej2-layouts/dist/global/ej2-layouts.min.js" type="text/javascript"></script>
            <script src="resources/ej2-buttons/dist/global/ej2-buttons.min.js" type="text/javascript"></script>
            <script src="resources/ej2-popups/dist/global/ej2-popups.min.js" type="text/javascript"></script>
            <script src="resources/ej2-data/dist/global/ej2-data.min.js" type="text/javascript"></script>
            <script src="resources/ej2-inputs/dist/global/ej2-inputs.min.js" type="text/javascript"></script>
            <script src="resources/ej2-lists/dist/global/ej2-lists.min.js" type="text/javascript"></script>
            <script src="resources/ej2-dropdowns/dist/global/ej2-dropdowns.min.js" type="text/javascript"></script>
            <script src="resources/ej2-splitbuttons/dist/global/ej2-splitbuttons.min.js" type="text/javascript"></script>
            <script src="resources/ej2-navigations/dist/global/ej2-navigations.min.js" type="text/javascript"></script>
            <script src="resources/ej2-grids/dist/global/ej2-grids.min.js" type="text/javascript"></script>
            <script src="resources/ej2-filemanager/dist/global/ej2-filemanager.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> element  -->
            <div id="filemanager"></div>
            <script>
              var hostUrl = 'https://ej2-aspcore-service.azurewebsites.net/';
              // initialize File Manager component
              var filemanagerInstance = new ej.filemanager.FileManager({
                  ajaxSettings: {
                      url: hostUrl + 'api/FileManager/FileOperations'
                  }
              });
              // render initialized File Manager
              filemanagerInstance.appendTo('#filemanager');
            </script>
       </body>
  </html>

Note: The ajaxSettings must be defined while initializing the file manager. File manager utilizes the URL’s mentioned in ajaxSettings to send file operation request to the server. The File Manager service link is given in hostUrl.

Step 6: Now, run the index.html in web browser, it will render the Essential JS 2 file manager component.

Step 1: The Essential JS 2 components scripts and styles are already hosted in the below CDN link formats.

Syntax:

Script: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Style: http://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: http://cdn.syncfusion.com/ej2/ej2-filemanager/dist/global/ej2-filemanager.min.js

Styles: http://cdn.syncfusion.com/ej2/ej2-filemanager/styles/material.css

Step 2: Have to add CDN global script and style for file manager and its dependent packages in myapp/index.html like below.

            <script>
              var hostUrl = 'https://ej2-aspcore-service.azurewebsites.net/';
              // initialize File Manager component
              var filemanagerInstance = new ej.filemanager.FileManager({
                  ajaxSettings: {
                      url: hostUrl + 'api/FileManager/FileOperations'

              filemanagerInstance.appendTo('#filemanager');
            </script>
       </body>
  </html>

When referencing CDN links in application, always ensure the network connection will be in enabled state.

Injecting feature modules

Basically, the file manager component contains a context menu for performing file operations, large-icons view for displaying the files and folders, and a breadcrumb for navigation. However, these basic functionalities can be extended by using the additional feature modules like toolbar, navigation pane, and details view to simplify the navigation and file operations within the file system. The above modules can be injected using the ej.filemanager.FileManager.Inject() method in the script as follows.

var hostUrl = 'https://ej2-aspcore-service.azurewebsites.net/';
// inject feature modules of the file manager
ej.filemanager.FileManager.Inject(ej.filemanager.DetailsView,ej.filemanager.Toolbar,ej.filemanager.NavigationPane);
// initialize File Manager component
var filemanagerInstance = new ej.filemanager.FileManager({
    ajaxSettings: {
        url: hostUrl + 'api/FileManager/FileOperations',
        getImageUrl: hostUrl + 'api/FileManager/GetImage',
        uploadUrl: hostUrl + 'api/FileManager/Upload',
        downloadUrl: hostUrl + 'api/FileManager/Download'
    }
});
// render initialized File Manager
filemanagerInstance.appendTo('#filemanager');

The following example shows you the File Manager with all feature modules.

            </script>
       </body>
  </html>

Note: The appearance of the File Manager can be customized by using cssClass property. This adds a css class to the root of the File Manager which can be used to add new styles or override existing styles to the File Manager.

Switching initial view of the File Manager

The initial view of the File Manager can be changed to details or largeicons view with the help of view property. By default, the File Manager will be rendered in large icons view. When the File Manager is initially rendered, created will be triggered. This event can be utilized for performing operations once the File Manager has been successfully created.

  </html>

Maintaining component state on page reload

The File Manager supports maintaining the component state on page reload. This can be achieved by enabling enablePersistence property which maintains the following,

  • Previous view of the File Manager - View
  • Previous path of the File Manager - Path
  • Previous selected items of the File Manager - SelectedItems

For every operation in File Manager, ajax request will be sent to the server which then processes the request and sends back the response. When the ajax request is success, success event will be triggered and failure event will be triggered if the request gets failed.

Note: The files of the current folder opened in the File manager can be refreshed programatically by calling refreshFiles method.

Rendering component in right-to-left direction

It is possible to render the File Manager in right-to-left direction by setting the enableRtl API to true.
