文章从网上搜索了三款js判断浏览器关闭哦，他们可以判断用户是关闭浏览呢，还是刷新浏览器，这都利用到了js onload unonload 等一些怪方法哦。
<script>
window.onbeforeunload = function()
{ var n = window.event.screenx - window.screenleft;
var b = n > document.documentelement.scrollwidth-20;
if(b && window.event.clienty < 0 || window.event.altkey)
{
//window.event.returnvalue = "1111";
userbasedao.upislogin(${adminbean.id});
}
}
window.onbeforeunload = function() {
var n = window.event.screenx - window.screenleft;
var b = n > document.documentelement.scrollwidth-20;
if(b && window.event.clienty < 0 || window.event.altkey) {
alert("是关闭而非刷新");
window.open(this.location);
//return false;
//window.event.returnvalue = ""; }
} else{
alert("是刷新而非关闭");
}
}
function promptonclose(e){
//e = e ? e : windowevent;
var promptstring = "你是否要离开此页面，离开该页面的信息将不被保存！";
//event.returnvalue = promptstring;
return promptstring;
}
if (window != top){
top.location.href = "www.baidu.com";
}else{
if (window.event) {
window.onbeforeunload = function(event) {
return promptonclose(event);
}
} else {
window.onbeforeunload = function() {
return promptonclose(event);
}
}
}
</script>
方法三
function closeo教程pen(event) {
if(event.clientx<=0 || event.clienty<0) {
//获取当前时间
var date=new date();
//将date设置为过去的时间
alert("关闭网页");
date.settime(date.gettime()-10000);
//将userid这个cookie删除
document.cookie="zhuangtao;expire="+date.toutcstring();
document.cookie="quanxianzifucuan;expire="+date.toutcstring();
document.cookie="quanxian;expire="+date.toutcstring();
s0 += "关闭窗口!"; sw = 1;
onbeforeunload();
// window.event.returnvalue = "关闭浏览器将退出系统.";
}
else
{
alert("刷新或离开");
}
}
var currentkeycode = -1;
function document.onkeydown() { // 本窗口的所有下属页面都必须含有本函数
top.currentkeycode = event.keycode;
}
function onbeforeunload(){
var sw = 0, s0 = "";
if (currentkeycode == 116)
