captureEvents()method to capture events at a high level, it doesn't feature the
releaseEvents()method to stop capturing the events. Therefore, the only way to disable an event handler is to completely delete it. For example, the following statement specifies an
onclickevent handler for the document object:
while the following statement disables the event handler:
document.onclick = functionName;
Once you assign
document.onclick = null;
nullto the event handler property, it does not have any function to process an event that comes its way. In other words, the
nullvalue disables the object's event handler.
Note that this technique is also supported in Navigator. It can be used for any object, and for any event handler. Learn more about event handlers in Column 10, The Internet Explorer Event Model.
