传单：当边界发生变化时触发事件 [英] Leaflet : Firing an event when bounds change

问题描述

我正在使用传单开发新的应用程序。
您可以在这里了解应用程序。

I am using leaflet to develop a new application. You can have an idea of the app here.

我想在地图边界发生变化时触发事件。
我查看了文档但找不到与此相关的任何内容。

I would like to fire an event whenever the bounds of the map change. I looked at the doc but couldn't find anything related to that.

我找到了 getBounds（）方法，以及可能事件方法，但两者都没有结合。

I have found the getBounds() method, and the list of possible event methods, but nothing combining both.

我看到的另一个可能性是检查鼠标拖动和滚动事件并检查每次都有界限。
但我希望有更好的事情要做。

The only other possibility I see to do that is to check for mouse drag and scroll events and check the bounds every time. But I was hoping there would be something better to do.

你有更好的主意吗？
谢谢！

Would you have a better idea? Thanks!

推荐答案

每次移动地图时（通过平移或缩放）都会更新地图边界。所以你可以为你的目的使用moveend事件

Map bounds are updated each time the map is moved (either by pan or zoom). So you can use moveend event for your purpose

map.on('moveend', function(e) {
   var bounds = map.getBounds();
});
