Available in Requirement set DocumentEvents
Added in 1.1
Office.context.document.removeHandlerAsync(eventType [, options], callback);


Name Type Description Support notes
eventType EventType Specifies the type of event to remove. Required.
options object Specifies any of the following optional parameters:
handler object Specifies the name of the handler to remove.
asyncContext array, boolean, null, number, object, string, or undefined A user-defined item of any type that is returned in the AsyncResult object without being altered.
callback object A function that is invoked when the callback returns, whose only parameter is of type AsyncResult.

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 removeHandlerAsync 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 object or data 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.


If the optional handler parameter is omitted when calling the removeHandlerAsync method, all event handlers for the specified eventType will be removed.


The following example removes the event handler named 'MyHandler'.

function removeSelectionChangedEventHandler() {
    Office.context.document.removeHandlerAsync(Office.EventType.DocumentSelectionChanged, {handler:MyHandler});
