jQuery cookie读取/写入表单

Question

我一直在使用演示网站，因为昨天，并在我自己的网站上做了一个版本。

这里是演示网站： http://rikrikrik.com/jquery/autosave/

这里是确切的代码是在我的网站： http://jsfiddle.net/EswfB/1/

问题： 删除相关的cookie无法正常工作。

它有时有效，有时不起作用。通常只有当我点击它时才会起作用，刷新，点击恢复并再次点击删除。

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

使用Chrome和FF。

任何想法？

单击删除相关cookie时，地址栏不会显示href =“＃”的标志。同时删除相关的cookies不做任何事。

我会推荐在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：

<p><button class="autosave" OnClick="save()">Save form</button> <button class="autosave_restore" OnClick="load()">Restore form</button> <input type="RESET" value="Default Form"> <button OnClick="deleteStorage()" class="autosave_removecookies">Delete related cookies</button> <span class="autosave_saving" id="autosave_saving"></span></p>
