Event handler scope in Javascript

Question

This is probably an easy question but I can\'t figure out the best answer for it.

I have 10

elements on screen. Each of them has a cli

Answer 1

So your problem is the nature of doing async code inside of loops as the other post said. In your case though there's altogether a better way to solve this problem and that's using event delegation.

document.body.onclick = function(e) {
  if (e.target.tagName.toLowerCase() === "div") {
    alert( "Element " + e.target.id );
  }
}

If you had jQuery you could do this:

$(document.body).on("click", "div", function() {
  alert($(this).attr("id"));
});

Obviously jQuery and other libs handle this stuff automatically as well.
