I am aware of the fact that variations of that question were asked many times before. Looking through Google output I found pages with examples like that:
function point_it(event) {
pos_x = event.offsetX ? (event.offsetX) : event.pageX - document.getElementById("pointer_div").offsetLeft;
pos_y = event.offsetY ? (event.offsetY) : event.pageY - document.getElementById("pointer_div").offsetTop;
document.pointform.form_x.value = pos_x;
document.pointform.form_y.value = pos_y;
}
The code works, but when I look at MouseEvent.offsetX it says "This is an experimental technology...".
So my question is, is it save to use the above construction or not? Is it better to learn how to use JQuery?
