把鼻子配制成一个div块

然后在div块里面添加一个mouseenter方法

例子：

var dov = document.getElementsByClassName("yincangkuang2")[0]

alert("创建对象成功")

dov.addEventListener("mouseenter",function(){

alert("成功进入方法")

document.getElementById("yincangkuang1").style.color = "#00c"

alert("老铁稳")

document.getElementsByClassName("yincangkuang")[0].style.display = "block"

},true)

$(document).on('click',function(event){

判断event.target 来源dom对象，

如果是你指定的input或者select ,return false

$('xxx').hide()

})
