我试图在谷歌 Map 上显示一些命中标记,并显示从开始到结束的路线 .
我有路线显示,但我的出发地和目的地有完全相同的坐标,导致目的地标记(标记'D')与原点标记重叠,如下所示:
理想情况下,我只想隐藏目标标记,但我完全不知道如何抑制单个标记 .
displayRoute函数
displayRoute(directionsService, directionsDisplay) {
let numberOfHits = this.geo.Data.rows.length - 1;
let firstHit = this.geo.Data.rows[numberOfHits];
let lastHit = this.geo.Data.rows[0];
let wayPoint, i;
let wayPointsArray = [];
this.checkForDuplicates('Id', this.geo.Data.rows);
for (i = 1; i < numberOfHits; i++) {
wayPoint = this.geo.Data.rows[i];
if (this.duplicatesArr.indexOf(wayPoint.Id) === -1) {
wayPointsArray.unshift({
location: {
lat: wayPoint.latitude,
lng: wayPoint.longitude
}
});
} else if (this.duplicatesArr.indexOf(wayPoint.Id) > -1) {
console.log('wayPoint', wayPoint.Id, 'has already been hit')
}
}
let request = {
origin: {
lat: firstHit.latitude,
lng: firstHit.longitude
},
destination: {
lat: lastHit.latitude,
lng: lastHit.longitude
},
waypoints: wayPointsArray,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
if((request.origin.lat == request.destination.lat) && (request.origin.lng == request.destination.lng)) {
// Code to hide destination marker
}
directionsService.route(request, (response, status) => {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
});
}
地理数据
this.geo = {
"Data": {
"records": 7,
"total": 1,
"page": 1,
"rows": [
{
"Id": 2778,
"latitude": 51.509697,
"longitude": -2.2
},
{
"Id": 53,
"latitude": 50.980598,
"longitude": -1.36827
},
{
"Id": 2750,
"latitude": 51.152599,
"longitude": -1.34676
},
{
"Id": 2778,
"latitude": 51.509697,
"longitude": -2.2
}
]
}
}
任何有关这方面的帮助将不胜感激!
EDIT
我很抱歉,为了清楚起见,我在这里创建了DirectionsDisplay:
createMap() {
let directionsDisplay = new google.maps.DirectionsRenderer;
let directionsService = new google.maps.DirectionsService;
let map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP
});
let bounds = new google.maps.LatLngBounds();
map.fitBounds(bounds);
directionsDisplay.setMap(map);
this.displayRoute(directionsService, directionsDisplay);
};
这在displayRoute()函数之前使用

DirectionsRendererOptions具有
suppressMarkers
属性 .这将隐藏原点和目标标记 .
然后,您可以在原点坐标处添加自己的标记 . 基于您发布的代码的示例:
您没有发布完整的代码,因此以上暗示您删除了
var directionsDisplay = new google.maps.DirectionsRenderer();
的初始化(未包含)
