detachEvent method

[This documentation is preliminary and is subject to change.]

Unbinds the specified function from the event, so that the function stops receiving notifications when the event fires.


HRESULT retVal = object.detachEvent(event, pDisp);

Standards information

There are no standards that apply here.


  • event [in]
    Type: BSTR

    BSTR that specifies any of the standard DHTML Events.

  • pDisp [in]
    Type: IDispatch

    Pointer to an IDispatch interface that specifies the function previously set using the attachEvent method.

Return value


If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.


Behaviors that attach to events using the attachEvent method must explicitly call the detachEvent method to stop receiving notifications from the page when the ondetach event fires. Behaviors that attach to events using the PUBLIC:ATTACH element automatically stop receiving notifications when the behavior detaches from the element, and thus do not need to call the detachEvent method.
