谷歌地图api：xa和pa在界限中是什么？ [英] Google maps api: what are xa and pa in get bounds?

问题描述

Api引用告诉我getBounds（）返回SW和NE极值的坐标。当我把它叫做时，它返回给我一个xa和pa作为关键字的对象，每个关键字都有j和k作为关键字，这些坐标看起来是随机的。我试图在文档中找到它们，但什么也没得到。我可以编写自定义代码来查找min和max以自己确定它们，但是我想知道是否可以知道它们的含义。 解决方案

您应该使用：

  var bounds = map.getBounds（）; 
 var NE = bounds.getNorthEast（）; 
 var SW = bounds.getSouthWest（）; 
  

The Api reference tells me that getBounds() returns the coordinates for SW and NE extremes. When I call it, it returns me with a object with xa and pa as keys, each of them having j and k as keys where the coordinates are, seemingly randomly. I have tried to find them in the documentation but get nothing. I can write out custom code to find min and max to determine them myself, but I'm wondering if I can know what they mean.

解决方案

You should use:

var bounds = map.getBounds();
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
