JS获取当前地理位置的方法

var getLocation = function (successFunc, errorFunc) {   //successFunc获取定位成功回调函数，errorFunc获取定位失败回调  //首先设置默认城市  var defCity = {    id: '000001',    name: '北京市',    date: curDateTime()//获取当前时间方法  };  //默认城市  $.cookie('VPIAO_MOBILE_DEFAULTCITY', JSON.stringify(defCity), { expires: 1, path: '/' });  if (navigator.geolocation) {    navigator.geolocation.getCurrentPosition(function (position) {      var lat = position.coords.latitude;      var lon = position.coords.longitude;      //var map = new BMap.Map("container");  // 创建Map实例      var point = new BMap.Point(lon, lat); // 创建点坐标      var gc = new BMap.Geocoder();      gc.getLocation(point, function (rs) {        var addComp = rs.addressComponents;        var curCity = {          id: '',          name: addComp.province,          date: curDateTime()        };        //当前定位城市        $.cookie('VPIAO_MOBILE_CURRENTCITY', JSON.stringify(curCity), { expires: 7, path: '/' });        //alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street);        if (successFunc != undefined)          successFunc(addComp);      });    },    function (error) {      switch (error.code) {        case 1:          alert("位置服务被拒绝。");          break;        case 2:          alert("暂时获取不到位置信息。");          break;        case 3:          alert("获取位置信息超时。");          break;        default:          alert("未知错误。");          break;      }      var curCity = {        id: '000001',        name: '北京市',        date: curDateTime()      };      //默认城市      $.cookie('VPIAO_MOBILE_DEFAULTCITY', JSON.stringify(curCity), { expires: 1, path: '/' });      if (errorFunc != undefined)        errorFunc(error);    }, { timeout: 5000, enableHighAccuracy: true });  } else {    alert("你的浏览器不支持获取地理位置信息。");    if (errorFunc != undefined)      errorFunc("你的浏览器不支持获取地理位置信息。");  }};var showPosition = function (position) {  var lat = position.coords.latitude;  var lon = position.coords.longitude;  //var map = new BMap.Map("container");  // 创建Map实例  var point = new BMap.Point(lon, lat); // 创建点坐标  var gc = new BMap.Geocoder();  gc.getLocation(point, function (rs) {    var addComp = rs.addressComponents;    var curCity = {      id: '',      name: addComp.province,      date: curDateTime()    };    //当前定位城市    $.cookie('VPIAO_MOBILE_CURRENTCITY', JSON.stringify(curCity), { expires: 7, path: '/' });    //alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street);  });};var showPositionError = function (error) {  switch (error.code) {    case 1:      alert("位置服务被拒绝。");      break;    case 2:      alert("暂时获取不到位置信息。");      break;    case 3:      alert("获取位置信息超时。");      break;    default:      alert("未知错误。");      break;  }  var curCity = {    id: '000001',    name: '北京市',    date: curDateTime()  };  //默认城市  $.cookie('VPIAO_MOBILE_DEFAULTCITY', JSON.stringify(curCity), { expires: 1, path: '/' });};
