Classes in s7sdk.common

Class s7sdk.common.Download

Extends s7sdk.common.Button.

The Download is a button component which allows to download a PDF file associated with the catalog asset to the local system.

The application should specify an instance of MediaSetDesc or OrientationSetDesc corresponding to the current catalog using setMediaSet() API, Download component will automatically derive the name of associated PDF file by appending "pdf" suffix to the catalog name. Alternatively the application may pass the name of the asset to download explicitly using setDownloadableAsset() method call.

In any case, Download component will check for PDF availability on the server and dispatch s7sdk.StatusEvent.NOTF_ASSET_METADATA_READY event when the check is complete. The result of this check can be read using canDownload() API.

The following modifiers are supported:

contenturlcontentRootPathThe content root path. If no domain is specified, the domain from which the page is served is applied instead. Standard URI path resolution applies./is/content/

Defining the Appearance using CSS

The CSS class for styling the Download is .s7download. This button has four states: up, over, down and disabled. You can style these states by adding the state attribute selector to the CSS class. It is recommended that you define common CSS under the main class and only define the necessary distinctions when using attribute selectors.

CSS ClassAttribute SelectorDescription
.s7downloadstate=[up|over|down|disabled]Define the appearance of Download for the various states.
.s7tooltip(None)A global class selector that defines appearance for the tooltips. To disable tooltips set the display style to none.

Localized Symbols

Download also has text symbols that you can localize either in a preset or in the viewer page though the mechanisms provided by the ParameterManager. For more information on localization consult the ParameterManager API documentation and HTML5 Viewers SDK User Guide.

Example Code

This example demonstrates how to use the Download component in a simple viewer. In this example a Container object, a PageView object, and a Download object are created. Clicking the download button a file download dialog will appear and prompt user to save file to the local system. The code below does the following:

  1. The Scene7 HTML5 SDK is linked to the page and the required s7sdk components are included in the document head.
  2. CSS Styles are defined in the document head to control the appearance of the ZoomView and Download components.
  3. The s7sdk.Util.init() method is called to initialize the SDK.
  4. A ParameterManager object is created to handle component modifiers for the viewer.
  5. An initViewer() function is defined. This function initializes a couple of modifiers (hard coded for example purposes), then creates the component objects required for this simple example. The initViewer() function also adds event listeners that designate functions to handle relevant component events (which might be dispatched by the components as a result of user interactions, changes in a component's state, etc.).
  6. A handler function is defined to respond to the component event listener added in the initViewer() function.
  7. An event listener is added to the ParameterManager object that designates the initViewer() function as the handler to call when the Scene7 SDK is loaded and ready.
  8. Finally, the init() method is called on the ParameterManager object to start the viewer.

Method Detail
addEventListener(type, handler, useCapture)
Adds an event listener to the instance of the Download component. The handler function receives a DOM event object of type Event.

The events supported by the component are:

  • s7sdk.event.StatusEvent.NOTF_ASSET_METADATA_READY - Dispatched when component receives asset metadata. s7sdk.event.StatusEvent
  • Parameters:
    {String} type
    Event name, for example s7sdk.event.StatusEvent.NOTF_ASSET_METADATA_READY.
    {Function} handler
    Function to be called when the event gets dispatched.
    {Boolean} useCapture
    Register capture phase.

    {Boolean} canDownload()
    Returns the result of PDF availability check. If a downloadable asset is available on the server, it will return true, otherwise it will be false.
    {Boolean} result of PDF availability check

    Sets an explicit downloadable asset ID. This method overrides the default behavior and allows to pass custom ID of downloadable asset in cases when defaults will not work.
    {String} downloadId
    Explicitly sets downloadable asset ID.

    Sets the media set of the primary asset used by application. The component will extract the name of the primary catalog, append "pdf" suffix and use it as default downloadable asset ID. The method call is ignored if an explicit downloadable asset ID was set using setDownloadableAsset() call.
    {MediaSetDesc | OrientationSetDesc} mediaSet
    Sets the media set of the primary asset.
