谷歌地图多个折线

Question

我有一个有多个多边形的google map sample。我将new google.maps.Polygon函数更改为折线为

     new google.maps.Polyline({
                paths: arr,
                strokeColor: '#FF0000',
                strokeOpacity: 0.8,
                strokeWeight: 2,
                fillColor: '#FF0000',
                fillOpacity: 0.35
            })

但它没有划清界限。 Fiddle here。还有如何将对象名称设置为infowindow内容。我试过

 var infowindow = new google.maps.InfoWindow({
            content: i
        });

Answer 1

google.maps.Polyline没有paths属性。变化：

 new google.maps.Polyline({
            paths: arr,
            strokeColor: '#FF0000',
            strokeOpacity: 0.8,
            strokeWeight: 2,
            fillColor: '#FF0000',
            fillOpacity: 0.35
        })

要：

 new google.maps.Polyline({
            path: arr,
            strokeColor: '#FF0000',
            strokeOpacity: 0.8,
            strokeWeight: 2,
            fillColor: '#FF0000',
            fillOpacity: 0.35
        })
