office javascript api tutorial

When the user chooses the Populate button, the app pushes the displayed data as a custom XML part into the document. They enter new data, change existing data and delete unnecessary data within the content of the document. Welcome to the Office Add-ins documentation repo. Each .zip file contains a collection of XML files, called “parts,” which together make up the Office document. The Script Lab and Script Lab for Outlook add-ins, available free from AppSource, enable you to explore the Office JavaScript API while you're working in an Office program such as Excel or Outlook. API acts as a layer between your application and external service. This Runtime allows JavaScript scripts to be executed in OpenOffice.org. You can replace the custom XML part on the fly (as we did here), but as long as the part conforms to the schema to which the content controls are mapped, the content controls will show the mapped data. Or, reversing the scenario, a business could use the same Word document with mapped content controls but have the end user enter data into the content controls. The user types data into a cell in the table, presses Enter and then the Value column of the table automatically updates. Figure 1 shows how the view of this app looks. The CustomXmlPart Object The customXmlPart object represents a single custom XML part. Mail apps represent a unique set of capabilities within the JavaScript API for Office, allowing app developers and Exchange administrators to build powerful tools for working with e-mail items. In our code, we’ve passed in the Office.BindingType.Table value for the bindingType parameter of the method. When the document is saved, the data in the mapped content controls is saved back to the XML file. (You can tell which Office documents are in the OOXML file format because the extensions for those documents are now four-letter extensions, many of which end in “x,” for example “.docx” for a Word document, “.xlsx” for an Excel spreadsheet or “.pptx” for a PowerPoint document.). The demo driver that we show you how to create prints names of open files to debug output. The invoice manager sample is an example of a dynamic document scenario where a business wants to generate documents that draw data from a back-end system to produce invoices. You're welcome to expand the sample library in Script Lab by contributing new snippets to the office-js-snippets GitHub repository. The data in the region is bound to a named object in the app so that the app can access the data in the named region, even if the user has selected something else. Figure 12 Using the Method CustomXmlParts.getByNamespaceAsync. Through Script Lab, you can access a library of samples to quickly try out features or you can use a sample as the starting point for your own code. Host-specific APIs provide strongly-typed objects that can be used to interact with objects that are native to a specific Office application. (Note that addFromPromptAsync is available only in Excel and the Excel Web App.). Figure 11 Wiring Up an Event Handler for the Populate Button Click Event. From this event, the app can get to the data that has changed and react appropriately. download an app from the Microsoft Store 2. Figure 10 shows the invoice manager Packing Slip form when the content controls are mapped to a custom XML part in the document. Furthermore the examples can be used as a first starting point to modify an existing example to their own needs. Script Lab offers a number of features to help you explore the Office JavaScript API and prototype add-in functionality. The user inputs data into the form and then the form is scraped for the data. The refreshData function simply begins the chain of asynchronous calls that gets the table data from the worksheet by calling getBindingData. After we’ve parsed the results from the Web service, we call the locally defined removeHandler method. We’ll do just that—create a stock ticker workbook—in the next section as we examine the Binding object. For example, if the user adds a new column or row to the table, the scope of the bound region increases, too. This quick tutorial will guide you through setting up dev environment and run an example code add in The biggest advantage of Fetch over XMLHttpRequest(XHR) is that the former uses promises that make working with requests and responses far easier. The signature for the customXmlPart.addHanderAsync method is as follows: Note that the first required parameter is an Office.EventType enumeration, which specifies what kind of event in the apps for Office object model you want to handle. The key aspect of content controls that complements custom XML parts is data binding using XML mapping. (Of course, we also could’ve created different bindings to separate columns in the table, using the matrix coercion type. ASP.NET application exposed in SharePoint 5. When debugging, you’ll need to insert the app manually into your workbook (Insert tab | Apps for Office button). The TableBinding object, which underlies the binding, exposes properties for adding columns, adding rows and even deleting all of the data in the table. See Work with tables using the Excel JavaScript API for more information. This function creates an array of three objects that represent three customer orders. Figure 1 A Table Named “Stocks” in an Excel Workbook with Formulas and Conditional Formatting Applied. The removeHandlerAsync method takes a parameter, handler, which specifies the name of the handler to be removed. (See the section titled “Accessing Office File Content from an App for Office” in the second article in this series for details about the text and matrix data types in the JavaScript API for Office.). Data binding provides close integration between a specific region of data in the document and the app. Also, we’ve already added some “intelligence” to this workbook. I have Microsoft Office 2013 installed in a Windows 7 machine. Because we know the name of the region to which we want to bind—it’s the table titled “Stocks” on Sheet1—we used the addFromNamedItemAsync method to establish the binding. The getBindingData function contains a call to the Binding.getDataAsync method and returns the data as a TableData object. We’ll look more closely at these objects as we build the stock ticker app. In this tutorial, you'll use Visual Studio to create a PowerPoint task pane add-in that adds a photo and text to a slide, gets slide metadata, and navigates between slides. We also explored how to leverage custom XML parts in an app for Word to facilitate automated document creation. The Developer's Guide comes with a wide range of examples from all application areas which shows the use of the API in the context of the different functional areas. This feature may be useful in scenarios where someone else has shared their snippet with you by either publishing it to a GitHub gist or providing their snippet's YAML.
