我正在尝试为我的 Google 地图实现 OverlappingMarkerSpiderfier，它之所以有效，是因为当我单击标记时，我的标记能够“蜘蛛化”。
我的问题是，在我的 VS Code 开发控制台中，ESLint 仍然给我错误“OverlappingMarkerSpiderfier”未定义。我真的不知道问题出在哪里，因为当我单击它们时，我的标记按预期工作。下面是一张显示 OverlappingMarkerWorkers 的图片，即使 ESLint 出现错误：
我想摆脱该错误，以防将来因此而出现错误。我搜索了解决方案，很多人评论说 OverlappingMarkerSpiderfier 应该在 Google Maps 加载后加载。我已经这样做了，但错误仍然存在。
我异步加载我的谷歌地图；下面是我加载 Google 地图和 OverlappingMarkerSpiderfier 的 .js 文件：
import api_keys from './api_keys'
const API_KEY = api_keys.google_maps_api_key;
const CALLBACK_NAME = 'gmapsCallback';
let initialized = !!window.google;
let resolveInitPromise;
let rejectInitPromise;
const initPromise = new Promise((resolve, reject) => {
resolveInitPromise = resolve;
rejectInitPromise = reject;
});
export default function init() {
if (initialized) return initPromise;
initialized = true;
window[CALLBACK_NAME] = () => resolveInitPromise(window.google);
const script = document.createElement('script');
script.async = true;
script.defer = true;
script.src = `https://maps.googleapis.com/maps/api/jskey=${API_KEY}&callback=${CALLBACK_NAME}`;
script.onerror = rejectInitPromise;
document.querySelector('head').appendChild(script);
const spiderfier = document.createElement('script');
spiderfier.defer = true;
spiderfier.src = "https://cdnjs.cloudflare.com/ajax/libs/OverlappingMarkerSpiderfier/1.0.3/oms.min.js";
spiderfier.onerror = rejectInitPromise;
document.querySelector('head').appendChild(spiderfier);
return initPromise;
}
以下是我的 GoogleMaps 组件。OverlappingMarkerSpiderfier 实现位于“watch”中：
<template>
<div id="google-map">
</div>
</template>
<script>
import gMaps from '../lib/gMaps.js'
export default {
name: 'GoogleMaps',
props: {
events: Array
},
data() {
return {
map: null,
locations: []
}
},
async mounted() {
try {
const google = await gMaps();
const geocoder = new google.maps.Geocoder();
this.map = new google.maps.Map(this.$el);
geocoder.geocode({ address: 'USA'}, (results, status) => {
if (status !== 'OK' || !results[0]) {
throw new Error(status);
}
this.map.setCenter(results[0].geometry.location);
this.map.fitBounds(results[0].geometry.viewport);
});
} catch (error) {
console.error(error);
}
},
watch: {
async events() { //creates markers for the map; data is from a 3rd party API that is handled by a different component
try {
const google = await gMaps();
var oms = new OverlappingMarkerSpiderfier(this.map, {
markersWontMove: true,
markersWontHide: true,
basicFormatEvents: true
})
for(let i = 0; i < this.events.length; i++) {
let marker = new google.maps.Marker({
position: {
lat: parseInt(this.events[i].latitude, 10),
lng: parseInt(this.events[i].longitude, 10)
},
map: this.map,
title: this.events[i].title
})
let iw = new google.maps.InfoWindow({
content: this.events[i].description || 'No description available.'
});
google.maps.event.addListener(marker, 'spider_click', function() {
iw.open(this.map, marker);
});
oms.addMarker(marker);
}
}
catch(error) {
console.error(error)
}
}
}
}
