CustomXmlPart.removeHandlerAsync method (JavaScript API for Office v1.1)

JavaScript API for Office v1.1

Removes an event handler for a CustomXmlPart object event.

Last modified: June 12, 2014

customXmlPart.removeHandlerAsync(eventType, handler [,options], callback);

eventType

Type: EventType

Specifies the type of event to remove. Required.

For a CustomXmlPart object event, the eventType parameter can be specified as Office.EventType.NodeDeleted, Office.EventType.NodeInserted, Office.EventType.NodeReplaced, or the corresponding text values of these enumerations.

options

Type: object

Specifies the following optional parameters.

handler

Type: string

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.

function removeNodeInsertedEventHandler() {
    Office.context.document.customXmlParts.getByIdAsync("{3BC85265-09D6-4205-B665-8EB239A8B9A1}", 
        function (result) {
            var xmlPart = result.value;
            xmlPart.removeHandlerAsync(Office.EventType.NodeInserted, {handler:myHandler});
    });
}
