Script works well with Mozilla, For IE need to do further modification in finding the exact position by calculating different properties value. left click mouse to capture the area MessageBox will display results Press Esc to exit. position crosshair and right click mouse to anchor it 2. Mouse Coordinates position will be displayed here. Reports position and size of selected rectangle To select area: 1. If isDrawing is true, the event handler calls the drawLine function to draw a line from the stored x and y values to the current location. So, the task is to find the coordinates of the mouse over the screen. This means that vertical zero is the topmost point and horizontal zero is the leftmost point. The top left corner of the screen is (0, 0) i,e, X and Y coordinates are (0, 0). As the mouse moves over the page, the mousemove event fires. In JavaScript, we have methods that help us to capture the location of the mouse on the screen. * pageX and pageY gets the X and Y cursor coordinatesĭivObj.innerHTML = “Mouse X:”+ev.pageX + ” Mouse Y:”+ev.pageY ĭivObj = document.getElementById(“mouseCoord”) First we store the x and y coordinates of the mouse pointer in the variables x and y, and then set isDrawing to true. Definition and Usage The clientX property returns the horizontal client coordinate of the mouse pointer when a mouse event occurs. * Based on that collect pageX and pageY properties of the event object The coordinates of the mouse pointer when clicked: let x event.clientX let y event.clientY // Vertical Try it Yourself More examples below. * call getMouseCoordites function each time mouse movesĭocument.onmousemove=getMouseCoordinates * capture mousemove event, this statement will cause browser to capture mousemove event and list down all its properites After thinking for some time, its strike that everything related to the current state is stored in events. Suprisingly I forgot how to get the X and Y coordinates of mouse. What we want to do is figure out the exact click position when youĬlick anywhere inside the yellow container:įirst, we have the event listener setup to listen for aĬlick event: yellowContainer.Yesterday while working on a script and I wanted to know the cursor X, Y coordinates. When you move the mouse, you can see mouse events in the text area. In the example below each face and its features are separate elements. event.relatedTarget is the new under-the-pointer element, that mouse left for ( target relatedTarget ). In that thread, let's start by looking at a seeminglyįine approach that seems like it should give us the exact position of event.target is the element that the mouse left. Pointing thing! A Worthy (But Incomplete) AttemptĪ great way to learn is by understanding why something doesn't work Here works on a touch device where a stylus or your finger is the It can be implemented using the clientX and clientY methods of the event: event.clientX: It gives the horizontal coordinate of the event. "mouse" and "click" will appear often, just know that everything I show So, the task is to find the coordinates of the mouse over the screen. In this tutorial, I will explain the magic behind figuring out theĮxact pixel coordinates of where a click occurred. Something you may find yourself needing to do is figuringĪn example where knowing the exact click position isĬlick anywhere inside the gray box to see the red circle move to the Mouse (or another pointing device like a stylus or finger). For all sorts of interactive doo-dads you will beĬreating, chances are you will be making heavy use of the pageX and event.pageY in combination with the jQuery offset() method to get the position of mouse pointer relative to an element.
