uni app +vue 引用 百度地图API取位置,VUE用百度地图获取当前位置(城市)
1.在index.html 引入 百度js
<script src="http://api.map.baidu.com/api?v=2.0&ak=你的密钥" type="text/javascript"></script>
2.创建js文件,放入以下代码:
export default { init: function () { const AK = "lyFvtNiZ2fH1jWqGIRMAxDwDbMwvXgsv"; const BMap_URL = 'https://api.map.baidu.com/api?v=2.0&ak=' + AK + '&s=1&callback=onBMapCallback'; return new Promise((resolve, reject) => { // 如果已加载直接返回 if (typeof BMap !== 'undefined') { resolve(BMap); return true; } // 百度地图异步加载回调处理 window.onBMapCallback = function () { resolve(BMap); }; let getCurrentCityName = function () { return new Promise(function (resolve, reject) { let myCity = new BMap.LocalCity() myCity.get(function (result) { resolve(result.name) }) }) } // 插入script脚本 let scriptNode = document.createElement("script"); scriptNode.setAttribute("type", "text / javascript"); scriptNode.setAttribute("src", BMap_URL); document.body.appendChild(scriptNode); }); } }
3.需要用的组件里开始引用和调用
写在方法里,在mounted里调用–下面代码不可少
mounted() { var isWeixn = this.is_weixn(); if (isWeixn) { this.getCity(); } }, methods: { getCity() { map.init().then(BMap => { const locationCity = new BMap.Geolocation(); var that = this; locationCity.getCurrentPosition( function getinfo(options){ let city = options.address.city; //此处拿到位置相关信息 that.LocationCity = city; console.log(options) }, function (e){ that.LocationCity = '定位失败'; console.log('定位失败') }, {provider: 'baidu'} ) }) }, }
