Callback Value

When the function you passed to the callback parameter executes, it receives an AsyncResult object that you can access from the callback function's only parameter.

In the callback function passed to the releaseByIdAsync method, you can use the properties of the AsyncResult object to return the following information.

Property Use to...
AsyncResult.value Always returns undefined because there is no data or object to retrieve.
AsyncResult.status Determine the success or failure of the operation.
AsyncResult.error Access an Error object that provides error information if the operation failed.
AsyncResult.asyncContext Access your user-defined object or value, if you passed one as the asyncContext parameter.


Fails if the specified id does not exist.


Office.context.document.bindings.releaseByIdAsync("MyBinding", function (asyncResult) { 
    write("Released MyBinding!"); 
// Function that writes to a div with id='message' on the page. 
function write(message){ 
    document.getElementById('message').innerText += message;
