document.getElementById("window").style.display = "inline-block";
document.onclick = function(e) {
    var ele = document.elementFromPoint(e.clientX, e.clientY);

Answer 1

What you did was where you copied or wrote this code, there most likely was a bug in it. JSFiddle has been known to have such problems. What you have to do is type that section of code (1 line above the error and 1 line underneath it) in a simple editor such as Notepad or TextEdit, and then copy that over and replace your current code. I know its this error, as the Unexoected token ILLEGAL part of it meant that the hidden character which is placed there is obviously not JavaScript-compliant, therefore it is not a syntax error at all.

Works for me.
