我使用相同的代码从http://www.aspsnippets.com/Articles/Google-Maps-V3-Draw-route-line-between-two-geographic-locations-Coordinates-Latitude-and-Longitude-points.aspx在这里，我可以有一点 我试图改变笔触颜色的n个它没有反映在JavaScript改变颜色的谷歌地图V3的多折线行程

origin: src,

}, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
for (var i = 0, len = result.routes[0].overview_path.length; i < len; i++) {

}
}
});
}
}
}
</script>
<div id="dvMap" style="width: 500px; height: 500px">
</div>
</body>
</html>
并替换该行与
var poly = new google.maps.Polyline({ map: map, strokeColor: 'red' });
and i tried to add color using the below code as
var colorVariable = ["white","green","blue","yellow","rose"];
for(var a =0;a<=5;a++){
var polyOptions = {
strokeColor: colorVariable[a],
strokeOpacity: 1.0,
strokeWeight: 2
}
poly = new google.maps.Polyline({ map: map, strokeColor: polyOptions });
poly.setMap(map);
}
，但我没有得到不同颜色的笔，请说如何整合它什么是错在它
你是如何改变线的颜色？ –
使用代码的第二部分 –
我知道这一点，但是你想通过点击一个按钮来改变所有路线吗？ –
