jquery – 有没有办法解决忽略z-index的事件？

它类似于madeinstefanos的回答,但具体到你的例子..

var mouseX = 0;
var mouseY = 0;
var front = 0;
var BACk = 0;

function log(text) {
    $("#log").append(text + '<BR>');
}

function mouseWithin(SELEctor) {
  var pos = $(SELEctor).position();
  var top = pos.top;
  var left = pos.left;
  var height = $(SELEctor).height();
  var width = $(SELEctor).width();

  if (mouseX >= left && mouseY >= top && mouseX <= left + width 
                     && mouseY <= top + height) {
    return true;
  }
  return false;
}

$(document).bind('mousemove',function(E) {
    mouseX = e.pageX;
    mouseY = e.pageY;
    if (front == 1 && !mouseWithin("#front")) {
            front = 0;
            log('Front Leave');
    }
    if (BACk == 1 && !mouseWithin("#BACk")) {
            BACk = 0;
            log('BACk Leave');
    }    
    if (front === 0 && mouseWithin("#front")) {     
            front = 1;
            log('Front Hover');
    }
    if (BACk === 0 && mouseWithin("#BACk")) { 
            BACk = 1;
            log('BACk Hover');
    }        

});
