**一、注册Api账号，引用js库**

**二、编写坐标拾取js代码和html代码**

//按钮定义
    <div class="form-group">
        <label class="col-md-2 control-label"><span class="text-danger">*</span>坐标：</label>
        <div class="col-md-3">
            <div class="input-group">
                <span class="input-group-addon">经度</span>
                <input class="form-control" type="number" ng-model="entity.Longitude" required />
            </div>
        </div>
        <div class="col-md-3">
            <div class="input-group">
                <span class="input-group-addon">纬度</span>
                <input class="form-control" type="number" ng-model="entity.Latitude" required />
            </div>
        </div>
        <div class="col-md-3">
            <span class="btn btn-link" ng-click="mapShow()">点击坐标拾取</span>
        </div>
    </div>
    //弹出框定义
    <div id="mapModal" class="modal fade" tabindex="-1" role="dialog"
            data-backdrop="static">
        <div class="modal-dialog modal-lg" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
                    <h4 class="modal-title">拖动位置标记设置坐标</h4>
                </div>
                <div class="modal-body">
                    <div id="mapContainer" style="min-width:500px;min-height:500px;"></div>
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">确定</button>
                    </div>
                </div>
            </div>
        </div>
    </div>

js代码示例

//选择坐标处理
    var map;
    var marker;
    var init = function () {
        var center = new qq.maps.LatLng(39.916527, 116.397128);
        map = new qq.maps.Map(document.getElementById('mapContainer'), {
            center: center,
            zoom: 13
        });
        //获取城市列表接口设置中心点
        citylocation = new qq.maps.CityService({
            complete: function (result) {
                map.setCenter(result.detail.latLng);
                //添加标记
                marker= new qq.maps.Marker({
                    position: result.detail.latLng,
                    draggable: true,
                    map: map
                });
                //添加到提示窗
                var info = new qq.maps.InfoWindow({
                    map: map
                });
                qq.maps.event.addListener(marker, 'mouseup', function (e) {
                    //获取经纬度 e.latLng
                    //获取坐标 e.cursorPixel
                    info.open();
                    info.setContent('<div style="text-align:center;white-space:nowrap;' +
                        'margin:10px;">坐标：' + e.latLng.lat + ',' + e.latLng.lng + '</div>');
                    info.setPosition(e.latLng);
    
                    $scope.entity.Longitude = e.latLng.lng;
                    $scope.entity.Latitude = e.latLng.lat;
                    $scope.$apply();
                });
            }
        });
        //调用searchLocalCity();方法    根据用户IP查询城市信息。
        citylocation.searchLocalCity();
    }
    init();
    
    $scope.mapShow = function () {
        $('#mapModal').modal('show');
        if ($scope.entity.Latitude != undefined) {
            var point = new qq.maps.LatLng($scope.entity.Latitude, $scope.entity.Longitude);
            map.setCenter(point);
            marker.setPosition(point);
        }
    }

**三、添加或修改时坐标对应截图**
