events on 2 div at the same time on mouse over

Question

I'd like to know if there's a way to trigger events on 2 div at the same time on mouse over in javascript/jquery if they are both at the same location but on different z-index ?

Answer 1

Consider to use elementFromPoint() method:

DEMO jsFiddle {be aware of bug if using wrapped iframe and scolling body's iframe}

$divs = $("#one, #two").on('click.passThrough', function (e, ee) {
   var $el = $(this).hide();
  try {
    if (!ee) $("#msg").empty();
    $("<div/>").append($el.text()).appendTo($("#msg"));      
    ee = ee || {
      pageX: e.pageX,
      pageY: e.pageY
    };
    var next = document.elementFromPoint(ee.pageX, ee.pageY);
    next = (next.nodeType == 3) ? next.parentNode : next //Opera
    $(next).trigger('click.passThrough', ee);
  } catch (err) {
    console.log("click.passThrough failed: " + err.message);
  } finally {
    $el.show();
  }
    alert('div cliked: #' + this.id);
});

Listen "mousemove" event in wrapper div,
use event object pageX and PageY to find Cursor above both div or not.
