Google 地图 Api 按钮 "route to marker" / 转到 Google 地图

Question

我想知道是否可以在 Google 地图上设置一个按钮，将您重定向到 Google 地图，提交目的地地址，这样用户只需要输入his/her自己的地址来计算路由。

编辑：如果有一种方法可以直接使用简单的 link 实现自定义按钮（这会导致 Google 上的共享地图），那也可以正常工作。

编辑 2：在 google 文档 https://developers.google.com/maps/documentation/javascript/examples/control-custom

的帮助下自行解决

花了很多 js 摆弄，但它现在可以工作了

Answer 1

目标-URL 将是：

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

注意 dir 后面的 2 个斜杠，当你使用 1 个斜杠时，地址将用作起始地址。地址必须经过编码（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 Google 地图文档中的示例以供将来参考。资料来源：https://developers.google.com/maps/documentation/javascript/examples/control-custom

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

/**
 * The CenterControl adds a control to the map that recenters the map on
 * Chicago.
 * This constructor takes the control DIV as an argument.
 * @constructor
 */
function CenterControl(controlDiv, map) {

  // Set CSS for the control border.
  var controlUI = document.createElement('div');
  controlUI.style.backgroundColor = '#fff';
  controlUI.style.border = '2px solid #fff';
  controlUI.style.borderRadius = '3px';
  controlUI.style.boxShadow = '0 2px 6px rgba(0,0,0,.3)';
  controlUI.style.cursor = 'pointer';
  controlUI.style.marginBottom = '22px';
  controlUI.style.textAlign = 'center';
  controlUI.title = 'Click to recenter the map';
  controlDiv.appendChild(controlUI);

  // Set CSS for the control interior.
  var controlText = document.createElement('div');
  controlText.style.color = 'rgb(25,25,25)';
  controlText.style.fontFamily = 'Roboto,Arial,sans-serif';
  controlText.style.fontSize = '16px';
  controlText.style.lineHeight = '38px';
  controlText.style.paddingLeft = '5px';
  controlText.style.paddingRight = '5px';
  controlText.textContent = 'Center Map';
  controlUI.appendChild(controlText);

  // Setup the click event listeners: simply set the map to Chicago.
  controlUI.addEventListener('click', function() {
    map.setCenter(chicago);
  });

}

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    zoom: 12,
    center: chicago
  });

  // Create the DIV to hold the control and call the CenterControl()
  // constructor passing in this DIV.
  var centerControlDiv = document.createElement('div');
  var centerControl = new CenterControl(centerControlDiv, map);

  centerControlDiv.index = 1;
  map.controls[google.maps.ControlPosition.TOP_CENTER].push(centerControlDiv);
}

/* Always set the map height explicitly to define the size of the div
 * element that contains the map. */
#map {
  height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}

<div id="map"></div>
<!-- Replace the value of the key parameter with your own API key. -->
