Power of javascript

Meanwhile, the somewhat opposite functionality - executing Javascript in PDF documents - is available for quite a long time already. This article is about this functionality.

The Office object represents a specific instance of an app inserted into a document, workbook, presentation, project, e-mail message or appointment. It can access bindings between the app and the document using the select method. Most importantly, the Office object exposes the initialize event for the app, which allows you to build initialization logic for the app more on that in a future article.

Finally, the Office object contains a reference to the Context object for the app. In addition to storing the language settings for the app, the Context object provides the entry point to runtime capabilities in the JavaScript API for Office that are specific to the host in which the app was activated.

For example, you can access the document Document object associated with the app through the Context. However, this property returns a value only when called from within a host application that supports it, that is, from within a task pane or content app. If we attempt to access the Context.

Likewise with the Context. In a mail app, it returns the mailbox Mailbox object opened in the host application. Support for Task Pane and ContentApps in the Object Model For task pane and content apps, the Document object represents the document, workbook, presentation or project into which the app has been inserted.

Almost all of the techniques for accessing the content in the Office document require use of the Document object. For this reason, you might want to capture a reference to the Document object when the app initializes as shown in Figure 3.

Through the Document object, an app can get data for specific tasks, views, fields and resources in the project. An app can also add event listeners to monitor when the user changes the selected view, task or resource selected in the project.

An app can store and persist custom properties across app sessions in the same document using the Settings object. The properties travel with the document: If you share an Office file that contains an app with someone else, the custom properties stored in the app will be available when the other person reads the file.

Storing and retrieving settings using the property bag is simple. To get the properties out of the property bag, we use the Settings. Both the set and get methods are synchronous.

To store the settings across sessions, we need to call the Settings. Support for Mail Apps in the Object Model For mail apps, the Mailbox object provides the entry point of data access for mail-app-specific functionality. As the name implies, the Mailbox object corresponds to the mailbox of the current user and travels to wherever users read their e-mail—either in the Outlook client application or in the Outlook Web App.

In addition to providing access to individual e-mail messages and appointments through the Mailbox. Like the Document object for content and task pane apps, you might want to capture a reference to the Mailbox object when the app initializes, as shown in Figure 4.

This makes the custom properties available to the app no matter what message the user is looking at or how the user has accessed his mailbox in Outlook or the Outlook Web App.

For example, the same task pane app can be activated within Word, Excel, Project and PowerPoint provided that its manifest allows all of those capabilities.I have a need to create an integer value to a specific power (that's not the correct term, but basically I need to create 10, , , etc.) The "power" will be specified as a function parameter.
