Question

我从昨天开始就使用了一个演示网站，并在我自己的网站上制作了一个版本。

以下是演示网站： http://rikrikrik.com/jquery/autosave/

以下是我网站上的确切代码： http://jsfiddle.net/EswfB/1/

问题：删除相关的cookie无法正常工作。

它有时有效，有时则无效。通常只有在我点击它，刷新，点击恢复并再次点击删除时才能工作。

现在，演示网站和我的网站昨天工作正常，关闭我的机器，今天返回，但都没有工作。也不要在我的同事机器上工作。

使用Chrome和FF。

有什么想法吗？

点击删除相关的Cookie时，地址栏没有显示href =“＃”的迹象。删除相关的cookie也无效。

我建议在JavaScript中使用localStorage，这很容易管理。你会节省很多代码。 http://jsfiddle.net/EswfB/8/

function save() {
    var firstname = document.profileForm.First_name.value;
    var lastname = document.profileForm.Last_name.value;
    if(document.getElementById("GenderMale").checked) {
        var gender = "Male";
    }
    else if(document.getElementById("GenderFemale").checked) {
        var gender = "Female";
    }
    var howdowecontactyou = document.profileForm.How_do_we_contact_you.value;
    var preferredtimeofcontact = document.profileForm.Preferred_time_of_contact.value;
    var jobtitle = document.profileForm.Job_title.value;
    localStorage.setItem("firstname", firstname);
    localStorage.setItem("lastname", lastname);
    localStorage.setItem("gender", gender);
    localStorage.setItem("howdowecontactyou", howdowecontactyou);
    localStorage.setItem("preferredtimeofcontact", preferredtimeofcontact);
    localStorage.setItem("jobtitle", jobtitle);
    document.getElementById("autosave_saving").innerHTML = "Saved!";
}
function load() {
    var firstname =  localStorage.getItem("firstname");
    var lastname =  localStorage.getItem("lastname");
    var gender =  localStorage.getItem("gender");
    var howdowecontactyou =  localStorage.getItem("howdowecontactyou");
    var preferredtimeofcontact =  localStorage.getItem("preferredtimeofcontact");
    var jobtitle =  localStorage.getItem("jobtitle");
    document.profileForm.First_name.value = firstname;
    document.profileForm.Last_name.value = lastname;
    if(gender == "Male") {
        document.getElementById("GenderMale").checked = true;
        document.getElementById("GenderFemale").checked = false;
    }
    if(gender == "Female") {
        document.getElementById("GenderMale").checked = false;
        document.getElementById("GenderFemale").checked = true;
    }
    document.profileForm.How_do_we_contact_you.value = howdowecontactyou;
    document.profileForm.Preferred_time_of_contact.value = preferredtimeofcontact
    document.profileForm.Job_title.value = jobtitle;
}
function deleteStorage() {
    localStorage.removeItem("firstname");
    localStorage.removeItem("lastname");
    localStorage.removeItem("gender");
    localStorage.removeItem("howdowecontactyou");
    localStorage.removeItem("preferredtimeofcontact");
    localStorage.removeItem("jobtitle");
}

和HTML：
