Hi all,

I want to clear graphics and close popup on the close() button of the popup. I am using the watch method and it works great.

The issue I have with this method is that when I click to start the event listener, I want the function to clear all popups in the map previously opened by other functions.

 $("#clicking").click(function () {
                view.popup.close();
});

Since the watch event removes layers when view.popup.visible === false

 // Watch view's stationary property for becoming true.
            watchUtils.whenFalse(view.popup, "visible", function (visible) {
                // Get the new center of the view only when view is stationary.
                console.log(visible)
                view.graphics.removeAll();
                layerbuffer.removeAll();
            });

I can only add the layers once the popup is opened.

onclickhandler = view.on("click", function (event) {
                        var visible1 = view.popup.visible;
                        $('#viewDiv').css('cursor', 'pointer');
                        view.graphics.removeAll();
                        layerbuffer.removeAll();
                        geombuffer = view.toMap({
                            x: event.x,
                            y: event.y
                        });
                        
                        pointGraphic = new Graphic({
                            geometry: geombuffer,
                            symbol: symboltoclone
                        });
                        var buffer = geometryEngine.geodesicBuffer(geombuffer, 2000, "feet");
                        var graphicbuffer = new Graphic({
                            geometry: buffer,
                            symbol: fillSymbol
                        });
                        layerbuffer.graphics.add(graphicbuffer);
                        view.graphics.add(pointGraphic);
                        //Set up query for geom
                        var queryTask = new QueryTask({
                            url: nitratequeryurl
                        });
                        //Query to return California geometry
                        var query = new Query();
                        //Set the query
                        query.geometry = buffer;  // the point location of the pointer
                        query.outFields = ["OBJECTID "]
                        //return geometry
                        query.returnGeometry = true;
                        //Intersects
                        query.spatialRelationship = "intersects";
                        //Execute the query
                        queryTask.executeForCount(query).then(function (response) {
                            
                            view.popup.open({
                                title: "Search Results",
                                location: geombuffer,
                                content: "<br><center>Number of nitrate-impacted wells within 2000 feet of:<br><br><center>" + "<center>" + geombuffer.latitude.toFixed(3).toString() + "N &nbsp" + "," + Math.abs(geombuffer.longitude).toFixed(3).toString() + "W</center><br>" + "<center><b>" + response + " Wells</b><br><center><br><i>Drag marker to update location</i></center>"
                            })
                            layerbuffer.graphics.add(graphicbuffer);
                            view.graphics.add(pointGraphic);
                           
                            view.goTo({
                                target: pointGraphic,
                                zoom: 15
                            });
                            
                            
                        });
                    });

Is there a way to clear graphics only if you click on the "close" button of the popup instead of the watch?

Alex,

   I'm a little confused. When are you adding the view.popup.watch code? If you do this as soon as the view is ready (i.e.view.when) then I don't see the problem...

Robert,

The only issue here is that I have to add the graphics after the popup is opened, in the query response. The popup opens first then graphic are added. I would like the graphics to be added before the popup is opened. 

queryTask.executeForCount(query).then(function (response) {

                    view.popup.open({
                        title: "Search Results",
                        location: geombuffer,
                        content: "<br><center>Number of nitrate-impacted wells within 2000 feet of:<br><br><center>" + "<center>" + geombuffer.latitude.toFixed(3).toString() + "N &nbsp" + "," + Math.abs(geombuffer.longitude).toFixed(3).toString() + "W</center><br>" + "<center><b>" + response + " Wells</b><br><center><br><i>Drag marker to update location</i></center>"
                    })
                    layerbuffer.graphics.add(graphicbuffer);
                    view.graphics.add(pointGraphic);

                    view.goTo({
                        target: pointGraphic,
                        zoom: 16
                    });

if I want to add the graphics first then I need to add the graphics in that section of the code:

 onclickhandler = view.on("click", function (event) {
                var visible1 = view.popup.visible;
                $('#viewDiv').css('cursor', 'pointer');
                view.graphics.removeAll();
                layerbuffer.removeAll();
                geombuffer = view.toMap({
                    x: event.x,
                    y: event.y
                });

                pointGraphic = new Graphic({
                    geometry: geombuffer,
                    symbol: symboltoclone
                });
                var buffer = geometryEngine.geodesicBuffer(geombuffer, 2000, "feet");
                var graphicbuffer = new Graphic({
                    geometry: buffer,
                    symbol: fillSymbol
                });
                layerbuffer.graphics.add(graphicbuffer);
                view.graphics.add(pointGraphic);
                //Set up query for geom
                var queryTask = new QueryTask({
                    url: nitratequeryurl
                });
                //Query to return California geometry
                var query = new Query();
                //Set the query
                query.geometry = buffer;  // the point location of the pointer
                query.outFields = ["OBJECTID "]
                //return geometry
                query.returnGeometry = true;
                //Intersects
                query.spatialRelationship = "intersects";

However, only the popup will show up because the view.popup.watch would clear it up because the popup is not visible

 // Watch view's stationary property for becoming true.
            watchUtils.whenFalse(view.popup, "visible", function (visible) {
                // Get the new center of the view only when view is stationary.
                console.log(visible)
                view.graphics.removeAll();
                layerbuffer.removeAll();
            });

Alex,

   I can't quite wrap my head around this. Could you have your full code?

My code is here: JS Bin - Collaborative JavaScript Debugging 

It behaves a little different than on my end but you I start the click handler, it works in the first click, the second click removes the graphics because the popup visibility is set to false.
