![]() Var mp = webMercatorUtils.webMercatorToGeographic(evt.mapPoint) ĭom.byId("info").innerHTML = mp.x.toFixed(3) + ", " + mp.y. the map is in web mercator but display coordinates in geographic (lat, long) after map loads, connect to listen to mouse move & drag events ![]() Use the coordinates to select the data on the canvas. To retrieve the color from a pixel of a specific canvas, we are going to : Retrieve the location of the mouse event. "esri/map", "esri/geometry/webMercatorUtils", "dojo/dom", This task is relatively easy to achieve using pure javascript without any kind of library.

Im wondering is it able to get user mouses position when user click on the plot What I want to achieve is. Since the map data is in Web Mercator the resulting coordinates will display in Web Mercator. plotly.js lazebear May 7, 2017, 9:52am 1. These events both pass map point coordinates to the showCoordinates function. One listens for onMouseMove and the other listens for onMouseDrag, but they both call the function showCoordinates:ĭojo.connect(map, "onMouseMove", showCoordinates) ĭojo.connect(map, "onMouseDrag", showCoordinates) These two lines add event listeners to the map. ![]() The first (var map) is the name of the object, the second ( esri.Map) is the name of the class, and the third ("map") is the name of the div which will contain the map. ![]() "Map" appears three times in the above line. Javascript mouse coordinates update#This is made possible by event listeners that update the the x and y coordinates while the mouse moves.
