VisualizaçõesOpción de eliminación de elementos de Openlayers con el botón derecho del mouse
Me gustaría habilitar la opción de eliminar después de hacer clic derecho en mi objeto. Hasta ahora, el código que proporcioné no funciona porque el navegador está verificando algunos dispositivos por mí, como puede ver a continuación:
Mi código se ve así:
var polygonInteraction = new ol.interaction.Draw({ type: 'Polygon', source: vectorLayer.getSource() }); polygonInteraction.setActive(false); polygonInteraction.on('drawend', onDrawend); polygonInteraction.on('drawend', function(e) { var title = prompt("Please provide the name", "default"); var value = prompt("Please provide the value", "undefinied"); var id = x++ e.feature.setProperties({ 'Id': id, 'Name': title, 'Value': value, }); function Rightcl(e) { var rightclick; if (e) var e = window.event; if (e.which) rightclick = (e.which == 3); else if (e.button) rightclick = (e.button == 2); alert('Delete me' + rightclick); // true or false }Me gustaría tener una opción para eliminar el objeto seleccionado después del clic derecho. ¿Cómo puedo hacerlo?
ACTUALIZAR:
Encontré una opción bastante buena para lograrlo:
lo que me llevó a una conclusión como esta:
console.info('contextmenu'); var feature = map.forEachFeatureAtPixel(map.getEventPixel(e), function (feature, layer) { return feature; }); if (feature) { selectInteraction.getFeatures() } return removeFeature }); var removeFeature = { text: 'Remove this object', classname: 'marker', callback: selectInteraction.getFeatures(), }basado también en la solución aquí:
https://rawgit.com/jonataswalker/ol-contextmenu/master/examples/contextmenu.js
pero hasta ahora hago clic derecho y la consola muestra el "menú contextual" solo para mí.
Mi JSfiddle completo está aquí:

¿Qué estoy haciendo mal aquí?
Gracias y Saludos

¿Necesita eliminar el último elemento? Solo desea borrar el mapa correctamente. Aquí mencioné el último elemento solo claro mientras hacía clic con el botón derecho.
var drawingManager; var selectedShape; var all_overlays = []; var gmarkers = Array(); var polygons = Array(); function setSelection(shape) { clearSelection(); selectedShape = shape; shape.setEditable(true); } function clearSelection() { if (selectedShape) { selectedShape.setEditable(false); selectedShape = null; } } function initialize() { var map = new google.maps.Map(document.getElementById('map'), { zoom: 10, center: new google.maps.LatLng(33.619003, -83.867405), mapTypeId: google.maps.MapTypeId.ROADMAP, disableDefaultUI: true, zoomControl: true }); var polyOptions = { fillColor: '#0099FF', fillOpacity: 0.7, strokeColor: '#AA2143', strokeWeight: 2, editable: true }; // Creates a drawing manager attached to the map that allows the user to draw Polygons drawingManager = new google.maps.drawing.DrawingManager({ drawingControlOptions: { drawingModes: [ google.maps.drawing.OverlayType.POLYGON ] }, polygonOptions: polyOptions, map: map }); google.maps.event.addListener(drawingManager, 'overlaycomplete', function (e) { calcIntersection(e.overlay, all_overlays); all_overlays.push(e.overlay); }); google.maps.event.addListener(map, "rightclick", function(event) { all_overlays[ all_overlays.length - 1].setMap(null); all_overlays.pop(); }); } function calcIntersection(newOverlay, allOverlays) { //ensure the polygon contains enought vertices if(newOverlay.getPath().getLength() < 3){ alert("Not enought vertices. Draw a polygon that contains at least 3 vertices."); return; } var geometryFactory = new jsts.geom.GeometryFactory(); var newPolygon = createJstsPolygon(geometryFactory, newOverlay); //iterate existing polygons and find if a new polygon intersects any of them var result = allOverlays.filter(function (currentOverlay) { var curPolygon = createJstsPolygon(geometryFactory, currentOverlay); var intersection = newPolygon.intersection(curPolygon); return intersection.isEmpty() == false; }); //if new polygon intersects any of exiting ones, draw it with green color if(result.length > 0){ newOverlay.setOptions({strokeWeight: 2.0, fillColor: 'green'}); } } function createJstsPolygon(geometryFactory, overlay) { var path = overlay.getPath(); var coordinates = path.getArray().map(function name(coord) { return new jsts.geom.Coordinate(coord.lat(), coord.lng()); }); coordinates.push(coordinates[0]); var shell = geometryFactory.createLinearRing(coordinates); return geometryFactory.createPolygon(shell); } google.maps.event.addDomListener(window, 'load', initialize);Enlace de demostración
