##Summary This sample shows how to use JavaScript in a Word 2013 task pane add-in to get the current document and slice it into chunks of data in user-defined sizes. The data could then be submitted to a service (such as an editing service, a translation service, or an e-book publishing service).

Prerequisites

This sample requires the following:

• Word 2013.
• Visual Studio 2013 (Update 5) or Visual Studio 2015, with Microsoft Office Developer Tools.
• Any browser that supports ECMAScript 5.1, HTML5, and CSS3, such as Internet Explorer 9, Chrome 13, Firefox 5, Safari 5.0.6, or a later version of these browsers.

Key components of the sample

The sample solution contains the following key files:

WordDocumentEmitter project

• WordDocumentEmitter.xml: The manifest file for the Word add-in.
• DocumentForEditing.docx: Start Document with 500 pages of text.

WordDocumentEmitterWeb project

• App/Home/Home.html. The HTML user interface that is displayed in the task pane.
• App/Home/Home.js. Logic that runs when the add-in is loaded.

##Description of the code The DocumentForEditing.docx file is set as the Start Document property of the task pane add-in. The document is large enough (500 pages) to be sliced into a number of discrete chunks of data.

The sample demonstrates:

• How to use JavaScript to retrieve the selected value from a drop-down list.
• How to use the getFileAsync method to slice the file into chunks of data of particular sizes.
• How to retrieve the data from each slice of the file by using the getSliceAsync method.

Build and debug

1. In Visual Studio, press F5 to build and deploy the sample add-in.
2. On the Home ribbon, click Open in the Document Slicer group.
3. In the task pane add-in, choose a size for the data chunk.
4. Click the Publish now! button.

The add-in displays the number of slices and the size of each slice, along with buttons you can use to view the content of each slice.

This sample displays the slice information to the user, but your add-in will probably send the data slices to a web service. The web service can then rebuild the presentation from the slices.

Troubleshooting

• If the add-in starts with a blank document, ensure that the Start Document property of the WordDocumentEmitter project is set to DocumentForEditing.docx (not to New Word Document).
• If the document opens in read-only mode, click the Enable editing button.
• If the add-in does not appear in the task pane of the document, Choose Insert > My Add-ins > Word Document Emitter.
