使用定位，逆地理编码，经纬度《=转=》地址信息、逆地理编码，地址《=转=》经纬度，贼方便！！！！

逆地理编码，经纬度=》地址信息

    var lnglat = [lng,lat];
    AMap.plugin("AMap.Geocoder", function() {
        var geocoder = new AMap.Geocoder({
          city: "010", //城市设为北京，默认：“全国”
          radius: 1000,//范围，默认：500
          extensions: "all"
        });
        geocoder.getAddress(lnglat, function(status, result) {
          if (status === "complete" && result.info === "OK") {
            // geocoder_CallBack(result);
            // console.log(result, "result");
            self.city = result.regeocode.addressComponent.city;
            self.resultData = result.regeocode.addressComponent.city;
            localStorage.localCity = result.regeocode.addressComponent.city;
            localStorage.timestamp = new Date().getTime();
            localStorage.position = JSON.stringify(position); //将即将纬度存到本地
          }
        });
      });

逆地理编码，地址-》经纬度

    var address= '山东省苍山县';//详细地址
    AMap.plugin("AMap.Geocoder", function() {
        var geocoder = new AMap.Geocoder({
          city: "010", //城市设为北京，默认：“全国”
          radius: 1000,//范围，默认：500
          extensions: "all"
        });
        geocoder.getAddress(address, function(status, result) {
          if (status === "complete" && result.info === "OK") {
            // geocoder_CallBack(result);
            // console.log(result, "result");
            self.city = result.regeocode.addressComponent.city;
            self.resultData = result.regeocode.addressComponent.city;
            localStorage.localCity = result.regeocode.addressComponent.city;
            localStorage.timestamp = new Date().getTime();
            localStorage.position = JSON.stringify(position); //将即将纬度存到本地
          }
        });
      });
