Question

我正在尝试使用JavaScript来创建和删除Cookie。我设置它的方式是，当用户点击接受按钮时，我创建一个cookie。如果他们点击拒绝按钮我将其删除。

但是我发现每次尝试删除cookie时它仍然存在。有人能告诉我我做错了吗？

创建COOKIE：

//Create Cookie
function createCookie(name, value, expires, path, domain) {
  var cookie = name + "=" + escape(value) + ";";
  if (expires) {
    // If it's a date
    if(expires instanceof Date) {
      // If it isn't a valid date
      if (isNaN(expires.getTime()))
       expires = new Date();
    }
    else
      expires = new Date(new Date().getTime() + parseInt(expires) * 1000 * 60 * 60 * 24);

    cookie += "expires=" + expires.toGMTString() + ";";
  }

  if (path)
    cookie += "path=" + path + ";";
  if (domain)
    cookie += "domain=" + domain + ";";
  document.cookie = cookie;
}

//Delete Cookie
function deleteCookie(name, path, domain) {
    console.log('deleting ' + name + ' cookie...');
    createCookie(name, "", -1, path, domain);
}

//Accept Button Click - CREATE COOKIE
$('#accept').click(function(e){
    e.preventDefault();
    console.log("You've accept our cookie policy!")
    createCookie("MyCookie", "Yummy", 2, "/", ".xyz.com");
});

//Decline Button Click - DELETE COOKIE
$('#decline').click(function(e){
    e.preventDefault();
    console.log("You've declined our cookie policy!");
    deleteCookie("myCookie", "/", ".xyz.com");
});

为了删除Cookie集，过期日期为过去的某些内容。

您的代码是正确的，只需在过期值中传递任何过期日期。
