APP端定位信息获取，百度定位

1.首先要在HTML页面引入

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=rKF3HrkL8UIRSvXs7OIsnMH9RbflSsdT"></script>

2.　在js中写入方法

var address = '';
    //百度地图定位
    function baiduMapPos() {
        var geolocation = new BMap.Geolocation();
        geolocation.getCurrentPosition(function(r) {
            if(this.getStatus() == BMAP_STATUS_SUCCESS) {
                var point = new BMap.Point(r.point.lng, r.point.lat); //用所定位的经纬度查找所在地省市街道等信息
                var gc = new BMap.Geocoder();
                gc.getLocation(point, function(rs) {
                    address = rs.address;
                    alert(address);
                });
            } else {
                address = 'fail';
                mui.alert('定位失败');
            }
        }, {
            enableHighAccuracy: true
        })
    }
