我想使用Here Maps和JavaScript一起使用自定义标记,但我尝试了文档,遗憾的是我不明白如何使用自定义图标设置自定义标记。
在下面的示例中,我设置了一个位置和标记,但我无法弄清楚如何使用.png
或.svg
图标设置我的自定义标记并设置为默认标记。
function addMarkersToMap(map) {
var parisMarker = new H.map.Marker({
lat: 48.8567,
lng: 2.3508
});
map.addObject(parisMarker);
var romeMarker = new H.map.Marker({
lat: 41.9,
lng: 12.5
});
map.addObject(romeMarker);
var berlinMarker = new H.map.Marker({
lat: 52.5166,
lng: 13.3833
});
map.addObject(berlinMarker);
var madridMarker = new H.map.Marker({
lat: 40.4,
lng: -3.6833
});
map.addObject(madridMarker);
var londonMarker = new H.map.Marker({
lat: 51.5008,
lng: -0.1224
});
map.addObject(londonMarker);
}
// Initialize the platform object:
const platform = new H.service.Platform({
app_id: 'XXXXXXXXXXXXXX',
app_code: 'XXXXXXXXXXX',
useCIT: true,
useHTTPS: true,
});
const maptypes = platform.createDefaultLayers();
// Instantiate (and display) a map object:
this.map = new H.Map(
this.$el.querySelector('#mapContainer'),
maptypes.normal.map, {
zoom: 4,
center: {
lat: 50,
lng: 5
},
},
);
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(this.map));
// Create the default UI components
var ui = H.ui.UI.createDefault(this.map, maptypes, 'pt-BR');
// Now use the map as required...
addMarkersToMap(this.map);
谢谢。
要将自定义图像指定为标记图标,请使用您的图像创建H.map.Icon
实例(并在需要时创建自定义选项):
// using a PNG icon with its natural size (which is 32x32 in this case)
var pngIcon = new H.map.Icon("https://cdn0.iconfinder.com/data/icons/daily-boxes/150/phone-box-32.png");
// optionally - resize a larger PNG image to a specific size
var pngIcon = new H.map.Icon("https://cdn3.iconfinder.com/data/icons/tourism/eiffel200.png", {size: {w: 56, h: 56}});
// optionally - resize a larger SVG image to a specific size
var svgIcon = new H.map.Icon("https://image.flaticon.com/icons/svg/190/190488.svg", {size: {w: 32, h: 32}});
然后,在创建特定标记(H.map.Marker)时,将icon
选项设置为自定义图标:
var marker = new H.map.Marker({
lat: 48.8567,
lng: 2.3508
}, {
icon: customIcon
}
);
或者,当您使用带有HTML / SVG内容的标记(H.mapDomIcon)时,您可以使用H.map.DomMarker。

据我所知,没有这样的功能只能为地图设置默认标记图标(例如map.setDefaultMarkerIcon(...)
)。要么在实例化标记时创建自定义图标,也可以使用它:
var icon = new H.map.Icon("...");
var marker = new H.map.Marker({lat: 48.8567, lng: 2.3508}, {icon: icon});
或者将标记创建封装到function
中并通过以下方式创建标记:
var defaultIcon = new H.map.Icon("...");
function createMarker(lat, lng) {
return new H.map.Marker({lat: lat, lng: lng}, {icon: defaultIcon});
}
var marker = createMarker(48.8564, 2.3564);

此外,您的示例代码还有一些可能导致错误的剩余代码,而不会引起注意:
this.$el.querySelector('#mapContainer')
所以为了提供一个工作示例,我只是使用一个更简单的解决方案来选择<div>
元素,它将用作地图容器:
document.querySelector('#mapContainer')
