Google Maps API v3:如何删除事件侦听器? [英] Google Maps API v3: How to remove an Event Listener?

问题描述

如何删除 Google Maps API 中的bounds_changed"事件侦听器v3?

google.maps.event.removeListener(_???_);    

推荐答案

通常您可以在 Google Maps API 文档中找到此类问题的答案.

Usually you can find answers to such questions in Google Maps API documentation.

正如 Andrew 所说，addListener 返回一个句柄，您可以稍后使用它来删除侦听器.这是因为单个事件可以有多个侦听器，要删除它们，您必须保存对每个附加侦听器的引用.

As Andrew said, addListener returns a handle which you can use later to remove the listener. That's because a single event can have many listeners and to remove them you must save a reference to each of attached listeners.

还有一个函数可以同时删除所有监听器:

There's also a function which removes all of the listeners at the same time:

clearListeners(instance:Object, eventName:string);
//In your case:
google.maps.event.clearListeners(map, 'bounds_changed');
