Exemplos

// The following example shows how you can instrument a batch of commands
// to determine where an error occurred. The first batch successfully
// inserts the first two paragraphs into the document and cause no errors.
// The second batch successfully inserts the third and fourth paragraphs
// but fails in the call to insert the fifth paragraph. All other commands
// after the failed command in the batch are not executed, including the
// command that adds the fifth trace message. In this case, the error
// occurred after the fourth paragraph was inserted, and before adding the
// fifth trace message.

// Run a batch operation against the Word object model.
await Word.run(async (context) => {

    // Create a proxy object for the document body.
    const body = context.document.body;

    // Queue a command to insert the paragraph at the end of the document body.
    // Start a batch of commands.
    body.insertParagraph('1st paragraph', Word.InsertLocation.end);
    // Queue a command for instrumenting this part of the batch.
    context.trace('1st paragraph successful');

    body.insertParagraph('2nd paragraph', Word.InsertLocation.end);
    context.trace('2nd paragraph successful');

    // Synchronize the document state by executing the queued-up commands,
    // and return a promise to indicate task completion.
    await context.sync();

    // Queue a command to insert the paragraph at the end of the document body.
    // Start a new batch of commands.
    body.insertParagraph('3rd paragraph', Word.InsertLocation.end);
    context.trace('3rd paragraph successful');

    body.insertParagraph('4th paragraph', Word.InsertLocation.end);
    context.trace('4th paragraph successful');

    // This command will cause an error. The trace messages in the queue up to
    // this point will be available via Error.traceMessages.
    body.insertParagraph(0, '5th paragraph', Word.InsertLocation.end);
    // Queue a command for instrumenting this part of the batch.
    // This trace message will not be set on Error.traceMessages.
    context.trace('5th paragraph successful');
    await context.sync();
}).catch(function (error) {
    if (error instanceof OfficeExtension.Error) {
        console.log('Trace messages: ' + error.traceMessages);
    }
});

// Output: "Trace messages: 3rd paragraph successful,4th paragraph successful"
