Sir I have a query this calculate area fn do not calculate instantly, i have it only calculate when i refresh the page and then its calculates total area from whole graohics. how to calculate area instantly when graphics is dropped on map or drawn on map
//Calculate TOtal hectares of Map Geometry
function calculateArea() {
var area = 0;
graphicsLayer.graphics.map(function (grap) {
area = geometryEngine.geodesicArea(grap.geometry, "hectares");
});
totalAreaHectare=totalAreaHectare+=Math.round(area);
//console.log(totalAreaHectare);
} //End calculateArea
});//End require
I am calling it in
function addGraphics(vertices) {
//const vertices = <?php echo json_encode($map_ring_coordinate);?>;
const polygon = createGeometry(vertices);
validSymbol = createSymbol([255, 255, 255, 0.3], "solid", 2, [
255, 121,5]);
newDevelopmentGraphic = new Graphic({
geometry: webMercatorUtils.geographicToWebMercator(polygon),
symbol: validSymbol,
attributes: {
newDevelopment: "new store"
}
});
graphicsLayer.addMany([newDevelopmentGraphic]);
calculateArea();
} //End addGraphics
and here
function addTempGraphic(evt) {
if(evt.state === "complete" && evt.tool === 'polygon'){
evt.graphic.symbol = createSymbol([255, 255, 255, 0.3], "solid", 2, [255, 121, 5]);
evt.graphic.attributes= {
newDevelopment: "new store"
};
calculateArea();
//appear polygon as editable first time when it is created
sketchViewModel.update(evt.graphic, {tool: "reshape"});
}
