多折线 - 需要更改颜色

Question

我是Google地图的新手 - 我试图更改地图上第二条多段线的颜色。

这里是我迄今为止〜

var direction = new GDirections(); 

direction.load("from: Oregon 99, near, Halsey, Oregon to: Oregon 34, near, Tangent, Oregon to: Interstate 5, near, Tigard, Oregon to: Oregon 217, near, Cedar Hills, Oregon to: U.S. 26, near, North Plains, Oregon to: U.S. 26, near, Tigard, Oregon to: Interstate 405, near, Portland, Oregon to: Interstate 5, near, Vancouver, Wa to: Interstate 5, near, Carrolls, Wa to: Washington 432, near, Longview, Wa to: Washington 433, near, Rainier, Oregon to: U.S. 30, Wauna, Oregon", {getPolyline:true}); 

GEvent.addListener(direction, 
        "load", 
        function(){ map.addOverlay(direction.getPolyline()); } 
); 

有人可以帮助我改变这种折线为任何其他颜色。

您可以尝试将direction.getPolyline()添加到变量中，然后将其添加为覆盖图，然后在添加它之后调用GPolyline.setStrokeStyle(GPolyStyleOptions)。以下是GPolyline.setStrokeStyle()和GPolyStyleOptions的一些参考文献
