获取城市或者省份（已解决，另附上代码及说明），不用谢

function getPosBaidu() {  
                alert("获取百度定位位置信息:");  
                plus.geolocation.getCurrentPosition(function getinfo(position){  
                    var str = position.address.city; //获取城市信息  
                    document.getElementById("addr").innerHTML = str;  
                    alert(str);  
                }, function(e) {  
                    alert("获取百度定位位置信息失败："   e.message);  
                }, {provider: 'baidu'});  
            }

参考的测试的数据格式

{"coordsType":"bd09ll","address":{"cityCode":"132","province":"重庆市","district":"渝北区","street":"红黄路","city":"重庆市","country":"中国"},"addresses":"中国重庆市渝北区红黄路xxx号","coords":{"latitude":29.594499,"longitude":106.545088,"accuracy":188,"altitude":5e-324,"heading":null,"speed":0,"altitudeAccuracy":0},"timestamp":1449220694000} at plus/geolocation.html:32
