1.js：根据地址得到经纬度
var myplace=$scope.place;//获取输入的地址
var geocoder = new google.maps.Geocoder();//创建geocoder服务
//调用geocoder服务完成转换
geocoder.geocode( { 'address': myplace}, function(results, status) {
    if (status==google.maps.GeocoderStatus.OK) {
        lat=results[0].geometry.location.lat();
        lng=results[0].geometry.location.lng();
        address=results[0].formatted_address;
        placeId = results[0].place_id;
        //cacheAddress(placeId, lat, lng, address);
    } else {
        alert('Geocode was not successful for the following reason: ' + status);
    }
});

2.js:反解析,根据经纬度得到地址

fn.callBack=function(data){
    if(data.status=="OK"){
        var lat=data.results[0].geometry.location.lat;
         var lng=data.results[0].geometry.location.lng;
         var address=data.results[0].formatted_address;
         var placeId=data.results[0].place_id;
        if(vm.radius == null || vm.radius.length == 0){
            alert("Please enter a radius.");
            return;
        }
        if(vm.radius<=0){
            alert("Radius must be greater than 0.");
            return;
        }
        cacheAddress(placeId, lat, lng, address,vm.radius);
    }
}

$scope.showPosition = function (position) {
    $scope.lat = position.coords.latitude;
    $scope.lng = position.coords.longitude;
    $scope.accuracy = position.coords.accuracy;
    $scope.$apply();
    $.ajax({
        url: 'http://maps.google.com/maps/api/geocode/json?latlng='+$scope.lat+','+$scope.lng+'&language=en&sensor=false',
        data: {},
        dataType:'JSON',
        success:function(data){
            fn.callBack(data);
        }
    });

}

$scope.showError = function (error) {
    switch (error.code) {
        case error.PERMISSION_DENIED:
            $scope.error = "User denied the request for Geolocation."
            break;
        case error.POSITION_UNAVAILABLE:
            $scope.error = "Location information is unavailable."
            break;
        case error.TIMEOUT:
            $scope.error = "The request to get user location timed out."
            break;
        case error.UNKNOWN_ERROR:
            $scope.error = "An unknown error occurred."
            break;
    }
    $scope.$apply();
}

$scope.getLocation = function () {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition($scope.showPosition, $scope.showError);
    }
    else {
        $scope.error = "Geolocation is not supported by this browser.";
    }
}
fn.locationMe=function(){
    /*$scope.coords = geolocation.getLocation().then(function(data){
        return {lat:data.coords.latitude, lng:data.coords.longitude};
    });*/
    /*console.log($scope.coords);31.2989513,121.5150925*/
    $scope.getLocation();
}
