Javascript 映射框自动完成获取长和宽
我正在vue组件中使用带有自动完成功能的Mapbox:Javascript 映射框自动完成获取长和宽,javascript,vue.js,mapbox-gl-js,Javascript,Vue.js,Mapbox Gl Js,我正在vue组件中使用带有自动完成功能的Mapbox: <template> <div> <div id='geocoder'></div> </div> </template> <script> import mapboxgl from 'mapbox-gl'; export default { data() { ret
<template>
<div>
<div id='geocoder'></div>
</div>
</template>
<script>
import mapboxgl from 'mapbox-gl';
export default {
data() {
return {
map: null
}
},
created() {
Event.$on('map-created', (map) => {
this.map = map;
let geocoder = new MapboxGeocoder({
accessToken: mapboxgl.accessToken,
});
document.getElementById('geocoder').appendChild(geocoder.onAdd(this.map));
});
}
}
</script>
从“mapbox gl”导入mapboxgl;
导出默认值{
数据(){
返回{
映射:空
}
},
创建(){
事件。$on('map-created',(map)=>{
this.map=map;
let geocoder=新MapboxGeocoder({
accessToken:mapboxgl.accessToken,
});
document.getElementById('geocoder').appendChild(geocoder.onAdd(this.map));
});
}
}
它正在工作,但当用户单击结果时,如何获得long和lat
有什么活动吗?在文档中找不到任何内容
谢谢 试试这个:
this.map.on('click', '[YOUR LAYER ID]', (event) => {
console.log(event.features[0].geometry.coordinates);
});
当我添加自己的图层时,它会帮助我。自动完成输入字段,而无需地图
