基于上一个文章发布一下调用百度地图搜索拿去当前的地理位置，页面有element-ui,记得去main.js配置element-ui，此处忽略
效果图：
拿去百度的接口获取需要的经纬度

拿到经纬度后，并且转换为当前地址的页面，这里面再次调用了百度的转换
data(){
return{
pointX: this.$route.query.pointX || "", // 经度
pointY: this.$route.query.pointY || "", // 纬度
city: "正在获取当前位置",
}}
getaddress(){
if (this.pointX != "" && this.pointY != "") { //判断拿去到的经纬度不为空的话，跳进方法
var point = new BMap.Point(this.pointX, this.pointY); //利用经纬度再次转换，获取当前的地理位置信息
var geoc = new BMap.Geocoder();
geoc.getLocation(point, rs => {
// console.log(this);
var addComp = rs.addressComponents;
this.city =
addComp.province + "-" + addComp.city + "-" + addComp.district;
console.log(this.city);
console.log(
addComp.province +
", " +
addComp.city +
", " +
addComp.district +
", " +
addComp.street +
", " +
addComp.streetNumber
);
});
return false
