谷歌地图Api按钮;路由到标记“/转到谷歌地图

Google Maps Api button for "route to marker" / go to Google Maps

本文关键字：谷歌地图 路由 Api 按钮      更新时间：2024-03-16

我想知道是否可以在谷歌地图上设置一个按钮，将您重定向到谷歌地图，提交目的地地址，这样用户只需输入自己的地址即可计算路线。

编辑：如果有一种方法可以直接实现一个带有简单链接的自定义按钮（这会导致谷歌上的共享地图），那么它也同样有效。

编辑2：设法在谷歌文档的帮助下自己解决了这个问题https://developers.google.com/maps/documentation/javascript/examples/control-custom

花了很多js的时间，但现在它可以工作了

目标URL为：

https://www.google.com/maps/dir//{encodedAddress}

注意dir后面有两个斜线，当您使用1个斜线时，地址将用作起始地址。地址必须编码（例如通过encodeURIComponent）

示例按钮（使用他的textContent作为地址）：

<button onclick="top.window.open('https://www.google.com/maps/dir//'+
                                  encodeURIComponent(this.textContent.trim()),
                                 'gmap')">
    Berlin
</button>

添加谷歌地图文档中的示例以供将来参考。来源：https://developers.google.com/maps/documentation/javascript/examples/control-custom

var map;
var chicago = {lat: 41.85, lng: -87.65};

function CenterControl(controlDiv, map) {
  // Set CSS for the control border.
  var controlUI = document.createElement('div');
