我正在处理公交路线,并且能够使用polylineOptions属性更改为公交路线显示的折线颜色。
但是,我无法更改为步行路线显示的虚线颜色。
我确实遇到过这个解决方案,但它不适用于v3(尝试使用v3.22)

我错过了哪些可用的属性,或者这是不可能的?
答案 0 :(得分:4)
这些行的选项是固定的,不会受DirectionsRenderer的折线选项影响。
这些虚线的polylineOptions将(当前)由API设置为:
{
"icons": [{
"icon": {
"path": 0,
"scale": 3,
"fillOpacity": 0.7,
"fillColor": "#00b3fd",
"strokeOpacity": 0.8,
"strokeColor": "#3379c3",
"strokeWeight": 1
},
"repeat": "10px"
}],
"strokeColor": "#000000",
"strokeOpacity": 0,
"strokeWeight": 5
}
...将忽略DirectionsRenderer的任何自定义折线选项。
可能的解决方法(但只能为所有这些虚线设置一个固定值):
function initMap() {
var goo = google.maps,
map = new goo.Map(document.getElementById('map'), {
zoom: 7,
center: {lat: 41.85, lng: -87.65}
}),
directionsService = new goo.DirectionsService,
directionsDisplay = new goo.DirectionsRenderer({
map:map,
polylineOptions:{
strokeColor:'red'
}});
google.maps.Polyline.prototype.setMap=(function(f,r){
return function(map){
if(
this.get('icons')
&&
this.get('icons').length===1
&&
this.get('strokeOpacity')===0
&&
!this.get('noRoute')
){
if(r.get('polylineOptions')&& r.get('polylineOptions').strokeColor){
var icons=this.get('icons'),
color=r.get('polylineOptions').strokeColor;
icons[0].icon.fillOpacity=1;
icons[0].icon.fillColor=color;
icons[0].icon.strokeColor=color;
this.set('icons',icons);
}}
f.apply(this,arguments);
}
})(
google.maps.Polyline.prototype.setMap,
directionsDisplay);
directionsService.route({
origin: new google.maps.LatLng(52.549917, 13.42539669),
destination: new google.maps.LatLng(52.541843, 13.4206566),
travelMode: google.maps.TravelMode.TRANSIT
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
} else {
window.alert('Directions request failed due to ' + status);
}
});
}

它会覆盖setMap
google.maps.Polyline
- 方法
检查是否
noRoute
- 属性(如果你自己绘制折线,哪个匹配前两个条件设置noRoute
- 选项为true,否则它们将也会受到影响)当所有3个条件都为真时,它将修改折线的icons-property。
答案 1 :(得分:1)
没有属性(当前)允许对折线的那部分进行样式设置。一个选项是隐藏DirectionRenderer折线并自己渲染折线,这样您就可以完全控制单独的折线。

strokeColor: '#C83939',
strokeOpacity: 1,
strokeWeight: 4

scale: 2,
strokeColor: '#C83939',
strokeOpacity: 1,
},
offset: '0',
repeat: '10px'
}]
};
