getBounds().contains 返回 false

Question

我希望检测到标记并显示分配给矩形的值。通过研究，我找到了this，但它不适用于我的情况，因为我只需要一个 latlong 点。我找到了与我想要的类似的东西并尝试了一下，即here

但它似乎不适用于我的情况。 我在下面有一个矩形：

var rectangle1 = new google.maps.Rectangle({
strokeColor: '#FF0000',
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: '#FF0000',
fillOpacity: 0.35,
map: map,
bounds: {
  north: -37.822802,
  south: -37.822260,
  east: 145.036010,
  west: 145.035324
}
});

我尝试插入一个点，即-37.822545, 145.035526，这个点在矩形内，它应该返回true，但事实并非如此。 Here is my JSfiddle

Answer 1

看起来google.maps.Rectangle 的LatLngLiteralBounds 输入已损坏。它创建了一个南北颠倒的矩形。使用您原来的矩形 (north: -37.822802, south: -37.822260)，我得到：

NE1:-37.822802,145.03601  (north=-37.822802, incorrect)
SW1:-37.82226,145.035324  (south=-37.82226, incorrect) 

如果我用google.maps.LatLngBounds 对象创建矩形，我会得到：

NE2:-37.82226,145.03601   (north=-37.82226, correct)
SW2:-37.822802,145.035324 (south=-37.822802, correct)

我认为您只是混淆了南北参数。 （较大的负纬度数比较小的负纬度数更南）

function initMap() {


var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 19,
    center: {
      lat: -37.82280243352756,
      lng: 145.0353240966797
    },
    mapTypeId: 'terrain'
  });

  var rectangle1 = new google.maps.Rectangle({
    strokeColor: '#FF0000',
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: '#FF0000',
    fillOpacity: 0.35,
    map: map,
    bounds: {
      south: -37.822802,  // This is further south ...
      north: -37.822260,  // than this
      east: 145.036010,
      west: 145.035324
    }
  });
  alert(rectangle1.getBounds());
  alert(rectangle1.getBounds().contains({lat:-37.822545, lng:145.035526}));
}

像这样切换南北，js-fiddle返回true。
