检查标记坐标是否在范围内 [英] Checking if marker coordinates are in bounds

问题描述

我正在Angular 6应用程序中使用传单地图.我以

I'm using leaflet map in Angular 6 application. I get location info for each item as

[lat:xx，lng:xx]

我还获得了bounds对象，该对象描述了当前可见的地图区域.它随拖动和缩放而变化.bounds对象看起来像这样:

I also get the bounds object which describes what area of map is currently visible. It changes with dragging and zooming. The bounds object looks like this:

_northEast
    lat: 76.16399261609192
    lng: 111.00585937500001
_southWest
    lat: 18.646245142670608
    lng: -43.76953125

我知道我可以比较每个项目 lat 是否大于 southWest.lat 和小于 northEast.lat ，并与em> lng ，但是有什么更简单，更优雅的方法来适应它吗?

I know I could just compare each item lat whether it's bigger than southWest.lat and smaller than northEast.lat and same with lng, but is there any easier and more elegant way to fit it in the bounds?

是的，我在询问之前仔细阅读了传单文档:)

And yes, I looked through the leaflet docs before asking this :)

推荐答案

您需要 LatLngBounds.contains(LatLng)
