我在rails应用程序中设置了一个不错的映射。一切都很好，但我不能用SnazzyMaps设计地图的样式。
这是我的map.js文件：
import GMaps from 'gmaps/gmaps.js';
const mapElement = document.getElementById('map');
if (mapElement) { // don't try to build a map if there's no div#map to inject in
const map = new GMaps({ el: '#map', lat: 0, lng: 0 });
const markers = JSON.parse(mapElement.dataset.markers);
const mapMarkers = map.addMarkers(markers);
mapMarkers.forEach((marker, index) => {
marker.addListener('click', () => {
// map.setCenter(markers[index]);
markers[index].infoWindow.open(map, marker);
})
});
if (markers.length === 0) {
map.setZoom(2);
} else if (markers.length === 1) {
map.setCenter(markers[0].lat, markers[0].lng);
map.setZoom(14);
} else {
map.fitLatLngBounds(markers);
}
}
import { autocomplete } from '../components/autocomplete';
// [...]
autocomplete();
在SnazzyMaps上，他们给出了以下示例。我的问题是，我应该在我自己的文件中插入这段代码的哪一部分。我试了一段时间了，但还是没能成功。这是SnazzyMaps的例子：
<!DOCTYPE html>
<html>
<head>
<title>Snazzy Maps Super Simple Example</title>
<style type="text/css">
/* Set a size for our map container, the Google Map will take up 100% of this container */
#map {
width: 750px;
height: 500px;
}
</style>

You need to include this script tag on any page that has a Google Map.
The following script tag will work when opening this example locally on your computer.
But if you use this on a localhost server or a live website you will need to include an API key.

要使用Gmaps库设置样式，您需要定义样式，然后将其设置为当前映射，如下所示：
const map = new GMaps({ el: '#map', lat: 0, lng: 0 });
var styles = [
{
stylers: [
{ hue: "#00ffe6" },
{ saturation: -20 }
]
}, {
featureType: "road",
elementType: "geometry",
stylers: [
{ lightness: 100 },
{ visibility: "simplified" }
]
}, {
featureType: "road",
elementType: "labels",
stylers: [
{ visibility: "off" }
]
}
];
map.addStyle({
styledMapName:"Styled Map",
styles: styles,
mapTypeId: "map_style"
});
map.setStyle("map_style");
