Get element at specified position - JavaScript

Using Javascript how can I identify the element at a given position? Basically I'm looking to write a function that takes two input parameters (the x and y coordinates) and returns the html element at the position on the screen represented by the parameters.



You can use the native JavaScript elementFromPoint(x, y) method, that returns the element at coordinates x,y in the viewport.

See the elementFromPoint w3c draft

And, a code sample:

function changeColor(newColor) {
    // Get the element placed at coords (2, 2)
    var elem = document.elementFromPoint(2, 2);
    // Set the foreground color to the element = newColor;
<p id="para1">Change this text color using the following buttons.</p>
<button onclick="changeColor('blue');">Blue</button>
<button onclick="changeColor('red');">Red</button>

You can use setInterval() to continuously check the element's hover event but it's not recommended, try to use .hover(...) and css instead to enhance the application performance.
