event.clientx code example

Example 1: get mouse position javascript

<p>Click in the div element below to get the x (horizontal) and y (vertical) coordinates of the mouse pointer, when it is clicked.</p>

<div onclick="showCoords(event)"><p id="demo"></p></div>

<p><strong>Tip:</strong> Try to click different places in the div.</p>

<script>
function showCoords(event) {
  var cX = event.clientX;
  var sX = event.screenX;
  var cY = event.clientY;
  var sY = event.screenY;
  var coords1 = "client - X: " + cX + ", Y coords: " + cY;
  var coords2 = "screen - X: " + sX + ", Y coords: " + sY;
  document.getElementById("demo").innerHTML = coords1 + "<br>" + coords2;
}
</script>

Example 2: svg clientx

var pt = svg.createSVGPoint();  // Created once for document

function alert_coords(evt) {
    pt.x = evt.clientX;
    pt.y = evt.clientY;

    // The cursor point, translated into svg coordinates
    var cursorpt =  pt.matrixTransform(svg.getScreenCTM().inverse());
    console.log("(" + cursorpt.x + ", " + cursorpt.y + ")");
}

Example 3: svg clientx

function clicked(evt){
    var e = evt.target;
    var dim = e.getBoundingClientRect();
    var x = evt.clientX - dim.left;
    var y = evt.clientY - dim.top;
    alert("x: "+x+" y:"+y);
}
