阻止事件冒泡兼容代码

//兼容代码
function stopPropagation(e) {
  e = e || window.event
  if(e.stopPropagation) { //w3c 阻止事件冒泡
    e.stopPropagation()
  }else{                  //IE 阻止事件冒泡
    e.cancelBubble = true
  }
}

//事件调用兼容代码
document.getElementById('dv2').onclick = function(e) {
  stopPropagation(e)
  console.log(2)
}
