Available in Requirement set	BindingEvents
Last changed in	1.1

bindingObj.removeHandlerAsync(eventType [, options], callback);

Parameters

Name	Type	Description
eventType	EventType	Specifies the type of event. 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 data or object to retrieve when removing an event handler.
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.

Remarks

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

Example

The following example removes the handler for the BindingDataChanged event named onBindingDataChanged.

function removeEventHandlerFromBinding() {
    Office.select("bindings#MyBinding").removeHandlerAsync(Office.EventType.BindingDataChanged, {handler:onBindingDataChanged});
}
