Available in requirement sets

BindingEvents

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

eventType

Type: EventType

Specifies the type of event. Required.

options

Type:object

Specifies the following optional parameters.

handler

Type: object

Specifies the name of the handler to remove. Optional.

asyncContext

Type: 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. Optional.

callback

Type: object

A function that is invoked when the callback returns, whose only parameter is of type AsyncResult. Optional.

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.

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

In version 1.1 of Office.js, you can now create table bindings in content apps for Access.

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

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