我正在尝试向路线添加信息窗口。有很多在标记上的事件侦听器上添加 InfoWindow 的示例。
但是我如何移动信息窗口以显示从一个标记到另一个标记的实际计划路线。之前已经有人尝试问过这个问题但没有回应（路线信息窗口).
不管怎样，我做了很多谷歌搜索，只发现了一个与此类似的问题，但又没有回应。
I tried infowindow.open(map,this)在回调中标记上的事件上，但它将在标记位置上打开信息窗口。只是我想像谷歌一样显示持续时间和距离。就像附图中的东西
var infowindow2 = new google.maps.InfoWindow();
distanceService.getDistanceMatrix(distanceRequest, function (response, status) {
if (status == "OK") {
infowindow2.setContent(response.rows[0].elements[0].distance.text + "<br>" + response.rows[0].elements[0].duration.text + " ")
}
else {
alert("Error: " + status)
}
})
infowindow2.open(map, this);
要找到路线上的位置并将信息窗口放在那里，请解析路线（详细信息在文档中有描述）。获取沿路线的位置，并使用该位置调用信息窗口的 setPosition 方法。
function calcRoute(start, end) {
var request = {
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
var step = 1;
var infowindow2 = new google.maps.InfoWindow();
infowindow2.setContent(response.routes[0].legs[0].steps[step].distance.text + "<br>" + response.routes[0].legs[0].steps[step].duration.text + " ");
infowindow2.setPosition(response.routes[0].legs[0].steps[step].end_location);
infowindow2.open(map);
}
});
}
