Infowindow仅适用于1条路线,不适用于谷歌地图

标签: google-maps google-maps-api-3 google-maps-markers

我在google地图中总共有5个位置,我已为此设置了标记并添加了标记之间的路径路径,在此路径之间我添加了infowindow,但它仅适用于1路线,不适用于其他3路线,可以有人请帮助我为什么它不适用于其他3条路线,关闭那个infowindow我无法打开那个infowindow,我们可以在路线之间设置一些点,并点击打开infowindow,任何人都可以帮我解决这个问题?

这里我添加了我的代码,

答案 0 :(得分:1)

的问题:

  1. 您需要为路线的每条腿创建一个InfoWindow,以显示该路段的距离和持续时间。
  2. 你需要计算&#34;中心&#34;每条腿设置该信息的位置。
  3.   for (var i = 0; i < route.legs.length; i++) {
        var routeSegment = i + 1;
        summaryPanel.innerHTML += "<b>Route Segment: " + routeSegment + "</b><br />";
        summaryPanel.innerHTML += route.legs[i].start_address + " to ";
        summaryPanel.innerHTML += route.legs[i].end_address + "<br />";
        summaryPanel.innerHTML += route.legs[i].distance.text + "<br /><br />";
        /*********** INFOWINDOW *****************/
        var legs = route.legs;
        var steps = legs[i].steps;
        var stepPath = [];
        for (j = 0; j < steps.length; j++) {
          var nextSegment = steps[j].path;
          for (k = 0; k < nextSegment.length; k++) {
            stepPath.push(nextSegment[k]);
          }
        }
        var center = stepPath[Math.floor(stepPath.length / 2)];
        var stepIW = new google.maps.InfoWindow();
        stepIW.setPosition(center);
        stepIW.setContent(response.routes[0].legs[i].duration.text + "<br>" + response.routes[0].legs[i].distance.text);
        stepIW.open(directionsDisplay.map);
      }
