如何防止或偵聽用戶在開發人員工具中刪除事件偵聽器？

這可能嗎？

在上面的示例中，當用戶刪除“事件偵聽器”時，我想對操作采取行動。 是否有事件偵聽器的事件偵聽器？

Answer 1

 const removeEventListenerOriginal = EventTarget.prototype.removeEventListener; const p = document.querySelector("p"); const onClick = e => console.log("clicked", e.target.tagName); EventTarget.prototype.removeEventListener = function(...args) { const [eventType, handler, capture] = args; console.log(`Event Listener Removed For`, this, { eventType, handler, capture }); // your logic here // call the original function or not. its up to you removeEventListenerOriginal.call(this, ...args); // or removeEventListenerOriginal.apply(this, args); } p.addEventListener("click", onClick); // try removing the event from dev console
