網(wǎng)上很多博客說監(jiān)聽窗口關(guān)閉事件使用window.beforeunload,但是這個監(jiān)聽事件也會在頁面刷新的時(shí)候執(zhí)行荒叶，經(jīng)過百度和自己的實(shí)際測試模庐，終于解決了這個問題贞盯，代碼如下：
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
//判斷是窗口關(guān)閉還是刷新
if(this._gap_time<=5){
//如果是登錄狀態(tài)镀赌，關(guān)閉窗口前氯哮，移除用戶
if(!this.showLoginButton){
$.ajax({
url: '/pictureweb/user/remove',
type: 'get',
async:false, //或false,是否異步
})
}
}
},
}
