MutationObserver 方法 disconnect() tells the observer to stop watching for mutations. The observer can be reused by calling its observe() method again.

句法

mutationObserver.disconnect()
					

参数

None.

返回值

undefined .

注意： All notifications of mutations that have already been detected ，但 not yet reported to the observer, are discarded.

用法注意事项

If the element being observed is removed from the DOM, and then subsequently released by the browser's garbage collection mechanism, the MutationObserver is likewise deleted.

范例

This example creates an observer, then disconnects from it, leaving it available for possible reuse.

const targetNode = document.querySelector("#someElement");
const observerOptions = {
  childList: true,
  attributes: true
}
const observer = new MutationObserver(callback);
observer.observe(targetNode, observerOptions);
/* some time later... */
observer.disconnect();
