单击jQuery中的按钮（切换地理围栏）时，显示多重数据的地理围栏

Question

以下是我切换地理围栏的代码， 单击按钮时，我需要显示多个路线的地理围栏 我的意思是onclick显示所有数据，而另一单击隐藏此，即切换

var beforeAnnCircleVisible
button().text('Show geofence').click(function () {
   _.each(route.routeStop, function (routeStop) {
                var stop =  db.index.stop[routeStop.stopId]
                var location = new google.maps.LatLng(+stop.latitude, +stop.longitude)
                var routeStopMarker = renderRouteStopMarker({map: map, location: location, routeStop: routeStop, showEta: false, showPosition: true})
                map.overlays.push(routeStopMarker)
                var beforeAnnCircle = new google.maps.Circle({
                  strokeColor: 'green',
                  strokeOpacity: 0.8,
                  strokeWeight: 1,
                  fillColor: 'green',
                  fillOpacity: 0.35,
                  map: map,
                  center: location,
                  radius: routeStop.beforeAnnRadius || 0,
                  visible: false,
                  editable: true,
                  draggable: false,
                  zIndex: 1,
                  hide: false
                })
                if (beforeAnnCircleVisible) {
                   beforeAnnCircleVisible = true
                   beforeAnnCircle.setVisible(true)
                   $(this).text('Hide geofence')
                  }
                  else {
                    beforeAnnCircleVisible = false
                   beforeAnnCircle.setVisible(false)
                   $(this).text('show geofence')
                  }
                })
                return false
              })

但是这里不起作用。我在这里想念什么。请建议
