js原生页面进入和离开,第1张

window.onload = function (e) {

var e = window.event || e

console.log(e)

}

window.onunload = function (e) {

var e = window.event || e

console.log(e)

}

window.onbeforeunload = function (e) {

var e = window.event || e

console.log(e)

}

注:

页面加载时只执行onload

页面关闭时先执行onbeforeunload,最后onunload

页面刷新时先执行onbeforeunload,然后onunload,最后onload

监听浏览器离开页面的操作:οnbefοreunlοad

具体如下:

<body οnbefοreunlοad="goodbye()">

window.οnbefοreunlοad=function(e){

var e = window.event||e

e.returnValue=("确定离开当前页面吗?")

}

不知道你说的不行是什么原因,可以贴出代码看看
