Open a document from file system

Opening a document in WebViewer from file system

Enable File Browser Option

If you wish to allow users to open files from their local file system, you can enable this feature with:

You can enable the file picker with Features at any point in time.

JavaScript (SDK v8.0+)

1WebViewer(...)
2  .then(instance => {
3    const { Feature } = instance.UI;
4    instance.UI.enableFeatures([UI.Feature.FilePicker]);
5  });

You can also specify this via the WebViewer constructor at the very beginning.

JavaScript

1WebViewer({
2  ...
3  enableFilePicker: true,
4}).then(instance => {
5    // ...
6  });

And this option will be available to users in the top-right of the WebViewer UI:

With a File Object

If you have the File object, from a file picker for example, you can pass the object directly to the loadDocument function. File objects are similar to Blobs and should load fine.
