【问题描述】：
我正在使用带有自动完成输入数据的谷歌地图，它有开始、中途停留和结束，我想更改谷歌地图的默认标记
我已经参考了这篇文章：
Change individual markers in google maps directions
如果我使用地图的默认标记，它运行正常
我的 HTML：
<div id="map_canvas"></div>
我的脚本：
<script>
function initMap() {
var map = new google.maps.Map(document.getElementById('map_canvas'), {
mapTypeControl: false,
center: {
lat: 16.318031,
lng: 107.432559
},
zoom: 5
});
new AutocompleteDirectionsHandler(map);
}
function AutocompleteDirectionsHandler(map) {
this.map = map;
this.originPlaceId = null;
this.destinationPlaceId = null;
this.destinationPlaceId2 = null;
this.travelMode = 'DRIVING';
var originInput = document.getElementById('start');
var destinationInput = document.getElementById('waypoints');
var destinationInput2 = document.getElementById('end');
var modeSelector = document.getElementById('mode-selector');
this.directionsService = new google.maps.DirectionsService;
this.directionsDisplay = new google.maps.DirectionsRenderer;
this.directionsDisplay.setMap(map);
var originAutocomplete = new google.maps.places.Autocomplete(originInput, {placeIdOnly: true});
var destinationAutocomplete2 = new google.maps.places.Autocomplete(destinationInput, {placeIdOnly: true});
var destinationAutocomplete = new google.maps.places.Autocomplete(destinationInput2, {placeIdOnly: true});
this.setupPlaceChangedListener(originAutocomplete, 'ORIG');
this.setupPlaceChangedListener(destinationAutocomplete, 'DEST');
this.setupPlaceChangedListener(destinationAutocomplete2, 'DEST2');
}
AutocompleteDirectionsHandler.prototype.setupClickListener = function(id, mode) {
var radioButton = document.getElementById(id);
var me = this;
radioButton.addEventListener('click', function() {
me.travelMode = mode;
me.route();
});
};
AutocompleteDirectionsHandler.prototype.setupPlaceChangedListener = function(autocomplete, mode) {
var me = this;
autocomplete.bindTo('bounds', this.map);
autocomplete.addListener('place_changed', function() {
var place = autocomplete.getPlace();
if (!place.place_id) {
window.alert("please input content.");
return;
}
if (mode === 'ORIG') {
me.originPlaceId = place.place_id;
} else if (mode === 'DEST') {
me.destinationPlaceId = place.place_id;
} else if (mode === 'DEST2') {
me.destinationPlaceId2 = place.place_id;
}
me.route();
});
};
AutocompleteDirectionsHandler.prototype.route = function() {
console.log("originPlaceId=" + this.originPlaceId + " destinationPlaceId=" + this.destinationPlaceId + " destinationPlaceId2=" + this.destinationPlaceId2);
if (!this.originPlaceId || !this.destinationPlaceId) {
return;
}
var me = this;
var waypts = [];
if (!!this.destinationPlaceId2) {
waypts.push({

'placeId': this.destinationPlaceId2
},

});
}
this.directionsService.route({

destination: {
'placeId': this.destinationPlaceId
},
waypoints: waypts,
optimizeWaypoints: true,
travelMode: this.travelMode
}, function(response, status) {
if (status === 'OK') {
me.directionsDisplay.setDirections(response);
var route = response.routes[0];
var summaryPanel = document.getElementById("directions-panel");
// For each route, display summary information.
summaryPanel.innerHTML = "";
// For each route, display summary information.
for (var i = 0; i < route.legs.length; i++) {
makeMarker(leg.start_address, icons.start, "title", map);
makeMarker(leg.stopover_address, icons.end, 'title', map);

当我更改另一个标记图像时，它无法从 3 个点获取标记图像，如何解决问题
【问题讨论】：
-
请提供一个 minimal reproducible example 来证明您的问题，包括所有必需的 HTML/CSS。
-
@geocodezip: 是的，我已经参考了你的来源，你能指导我解决问题吗
-
您缺少很多必需的 HTML，并且您没有提供任何必需的 CSS。
