为什么本地存储在页面刷新后甚至不应该打开也不工作?

[英]Why local storage is not working even it should not open after page refresh?

I am using this but the cookies message keeps appearing after everypge refresh and tab opening. 我正在使用它,但是cookie消息在每次刷新和打开选项卡后仍然出现。

 $(document).ready(function () {
    if (!!localStorage.getItem('firstVisitVisp')) {

        localStorage.setItem('firstVisitVisp', 'true');

        setTimeout(function () {
            $("#cookieConsent").fadeIn(200);
        }, 4000);

        $("#closeCookieConsent, .cookieConsentOK").click(function () {
            $("#cookieConsent").fadeOut(200);
        });
    }
});

You're nearly there - just remove the !! 您快到了-删除!! and change it to ! 并将其更改为! :

if (!localStorage.getItem('firstVisitVisp')) {...}
