Javascript 使用坐标在谷歌地图中创建边界区域

Javascript 使用坐标在谷歌地图中创建边界区域,javascript,html,google-maps,google-maps-api-3,Javascript,Html,Google Maps,Google Maps Api 3,我想使用API v3在Google地图中显示区域边界。我有一个客户覆盖区域的邮政编码列表,我已经将其转换为LatLng坐标,并可以使用它们创建多边形,但正如您所料,这是一个混乱的线条,而不是一个实体形状的区域 有人知道这是否可能,如果有,怎么做?或者是另一种方式。我在下面使用的代码: <script> function initMap() { var map = new google.maps.Map(document.getElementById('map'

我错了,多边形不必闭合

贝弗编辑: 你的多边形必须是闭合的。
正如我想你从哪里得到你的源代码一样,最后一点和第一点是一样的。

好的,这是我承诺的代码示例。这将为您提供一个正方形/矩形多边形,其中包含三角形坐标系中的所有点

// create new LatLngBounds
var bounds = new google.maps.LatLngBounds();

// extend bounds to contain each coordinate
for (var i = 0, i_end = triangleCoords.length; i < i_end; i++) {
    bounds.extend(triangleCoords[i]);
}

// get the NSEW corners of the bounds
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
var SE = { lat: SW.lat(), lng: NE.lng() };
var NW = { lat: NE.lat(), lng: SW.lng() };

// Construct the polygon.
