JavaScript Cookies检查/设置/删除 [英] JavaScript Cookies check/set/delete

问题描述

我只想检查cookie是否存在，
设置/重置cookie 1天，
，并在关闭窗口/选项卡时删除cookie

I just wanna check if a cookie exists, set/reset the cookie for 1 day, and delete the cookie when the window/tab is closed

我正在尝试使用JavaScript进行此操作，但是地狱JS是一种愚蠢的语言（我发誓），再加上我很愚蠢。

I'm trying to do this in JavaScript, but hell JS is one dumbass language(I swear), add to that I'm stupid.

无论如何，这就是我在做什么：

Anyways here's what i'm doing:

function checkcookie(name)
{
    //Can't figure this one out
    //I want to check wheather the cookie is set or not
    //if yes
    //{ reset cookie + ... }
    //else
    //{ set cookie + ... }
}

function setcookie(name,value,day)
{
    var expireDate = new Date();
    expireDate.setSeconds(expireDate.getSeconds()+day*24*60*60*1000);
    document.cookie = name + "=" + value + ";path=/;expires=" + expireDate.toGMTString();
}

function delcookie(name)
{
    setcookie(name,"",-1);
}

任何一种答案都应得到赞赏，并提前提出。

Any kind of answer is appreciated and thx in advance.

推荐答案

您可以在此处测试Quirksmode代码：

该代码正在运行，因此可能是其他原因导致您的问题...所以如果您在jsfiddle.net中运行它，将会看到它的作用-这可能有助于确定它是否是浏览器设置

The code is working so it must be something else causing your problem... so see what it does for you if you run it in jsfiddle.net - that might help determine if its a browser setting
