I'm using version 4.0 of the ArcGIS API for my maps. I have this problem with maps whenever the page has to be scrolled down to view the map. My map is somewhere in the middle of the page so the user has to scroll down to view it. Then if a certain point was clicked on the map or if a certain area in dragged to zoom in, the pointers the map shows as selection are not the exact points the mouse is pointing at. it points to a location above the mouse pointer.
Here is a sample code.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no">
<title>Add the Compass widget to a basic 2D map - 4.0</title>
<style>
html,
body,
#viewDiv {
padding: 0;
margin: 0;
height: 100%;
width: 100%;
}
</style>
<link rel="stylesheet" href="https://js.arcgis.com/4.0/esri/css/main.css">
<script src="https://js.arcgis.com/4.0/"></script>
<script>
require([
"esri/Map",
"esri/views/MapView",
"esri/widgets/Compass",
"dojo/domReady!"
],
function(
Map,
MapView,
Compass
) {
var map = new Map({
basemap: "national-geographic"
});
var view = new MapView({
container: "viewDiv",
scale: 500000,
center: [26.26, 39.17],
map: map
});
/********************************
* Create a compass widget object.
*********************************/
var compassWidget = new Compass({
view: view
});
// Add the Compass widget to the top left corner of the view
view.ui.add(compassWidget, "top-left");
});
</script>
</head>
<body>
<!-- add div for test-->
<div style="height:500px;"></div>
<div id="viewDiv"></div>
</body>
</html>
If you run this code you'll see if you scroll down and drag an area (by holding shift and dragging the mouse) it will drag an area above your selection.
