import geolocation from '@system.geolocation';
import battery from '@system.battery';

export default {
    data: {
        index: 0,
        latlon: "",
        accuracy: 0,
        battery: 0,
    },
    updateData() {
        var anchor = this;
        geolocation.getLocation({
            success: function (data) {
                anchor.latlon = "\n" + data.latitude + "\n" + data.longitude;
                anchor.accuracy = data.accuracy;
            }
        })
        battery.getStatus({
            success: function (data) {
                anchor.battery = data.level;
            }
        })
    },
    onInit() {
        this.updateData();
