窗口关闭/浏览器关闭之后处理内容，例如删除cookie、session、local storage 等
methods: {
beforeunloadHandler(e) {
console.log('关闭窗口之后')
}
}
// 绑定窗口关闭[监听]事件
mounted() {
window.addEventListener('beforeunload', e => this.beforeunloadHandler(e))
}
// 解除窗口关闭[监听]事件
destroyed() {
window.removeEventListener('beforeunload', e => this.beforeunloadHandler(e))
}
mounted() {
window.addEventListener('beforeunload', e => this.beforeunloadHandler(e))
window.addEventListener('unload', e => this.unloadHandler(e))
},
destroyed() {
window.removeEventListener('beforeunload', e => this.beforeunloadHandler(e))
window.removeEventListener('unload', e => this.unloadHandler(e))
},
methods: {
beforeunloadHandler(){
this._beforeUnload_time=new Date().getTime();
},
unloadHandler(e){
this._gap_time=new Date().getTime()-this._beforeUnload_time;
debugger
//判断是窗口关闭还是刷新
if(this._gap_time<=5){
//如果是登录状态，关闭窗口前，移除用户
if(!this.showLoginButton){
$.ajax({
url: '/pictureweb/user/remove',
type: 'get',
async:false, //或false,是否异步
})
}
}
},
}
window.beforeunload事件在window.unload事件之前执行。同时注意ajax请求方式必须为同步请求，所以不能使用axios,因为axios不能执行同步请求。参考
