我希望检测到标记并显示分配给矩形的值。通过研究,我发现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,它是 here
但它似乎对我的情况不起作用。 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
}
});
然后我尝试插入一个点,它是 -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
最佳答案
看起来像 LatLngLiteralBounds
google.maps.Rectangle
的输入被打破。它创建一个南北颠倒的矩形。使用您的原始矩形(北:-37.822802,南:-37.822260
),我得到:
NE1:-37.822802,145.03601 (north=-37.822802, incorrect)
SW1:-37.82226,145.035324 (south=-37.82226, incorrect)
而如果我用 google.maps.LatLngBounds
创建矩形对象,我得到:
NE2:-37.82226,145.03601 (north=-37.82226, correct)
SW2:-37.822802,145.035324 (south=-37.822802, correct)
(蓝色标记是 rectangle2
的 NE/SW,红色标记是 rectangle1
的 NE/SW。)
有人应该在 issue tracker 中创建问题
