和黑猫之家聊聊？

1.效果

        <location-picker :coord="coord" @change="onLocationPickerChange" />
        <el-button @click="coord = null">传null会关闭组件</el-button>
        <el-button @click="coord = ''">传空为当前定位</el-button>
        <el-button @click="coord = '22.984512,113.503624'">传指定经纬度</el-button>

2. 组件 LOCATIONPICKER.VUE

需要lodash-es的get和cloneDeep方法 npm i lodash --registry=https://registry.npm.taobao.org

3. 接口 API/MAP.JS

放些地图相关公用配置而已

export function getTXMapKey() {
    return 'you key';}123

4. 继续对扒下来的腾讯地图组件做点小修改符合自己需求

修改扒下来的 index-6781e3253a.js (https://blog.csdn.net/weixin_42405223/article/details/106302211 2.1 中 c 点 )

搜索

t._geocoder(e)1

按如下加上代码,目的是在地图有任务拖拽时候通过postMessage把相关经纬度给父窗口

window.parent.postMessage({module:'locationPicker',latlng:{lng:e.lng,lat:e.lat}}, "*");t._geocoder(e)1

搜索

var s=new qq.maps.LatLng(window.locInfo.lat,window.locInfo.lng);1

修改为以下,目的是在地图初始化完成后就把经纬度通过postMessage给父窗口

window.parent.postMessage({module:'locationPicker',latlng:{lng:window.locInfo.lng,lat:window.locInfo.lat}}, "*");var s=new qq.maps.LatLng(window.locInfo.lat,window.locInfo.lng);1

5. 调用

<template>
    <div class="app-container station-list">
        <location-picker :coord.sync="coord" @change="onLocationPickerChange" />
        <el-button @click="coord = null">传null会关闭组件</el-button>
        <el-button @click="coord = ''">传空为当前定位</el-button>
        <el-button @click="coord = '22.984512,113.503624'">传指定经纬度</el-button>
    </div></template>import LocationPicker from './components/LocationPicker';export default {
    components: {
        LocationPicker    },
    data() {
        return {
            coord: null
        };
    },
    methods: {
        onLocationPickerChange(location) {
            console.log(location);
        }
    }};</script>12345678910111213141516171819202122232425
