Getting a div scroll position using javascript.

Question

I have one button in a div tag. That div tag also has a vertical scroll bar.

If I scroll that bar and click on the button which is inside that div, it should return the scroll position as an alert message.

How to do that using JavaScript?

Answer 1

The scrollTop property tells you the vertical scroll position:

document.getElementById("yourButton").onclick = function() {
   alert(document.getElementById("yourDiv").scrollTop); 
}
