Question

我对javascript很新，并不确定我在做什么。现在我正在尝试将文本框数据以及一些字符串添加到cookie以显示在另一个页面上。文本框部分正在运行。

对于字符串，我正在使用单选按钮的值（用于多选测验验证），如果该值是该组的正确值，我想在cookie中添加一个字符串。我无法弄清楚这部分我做错了什么。

具体而言，不起作用的是gradeit（）函数中的内容

JS档案

var total = 5;
var right = 0;

//cookies
function addToCookie(id, value)
{
  document.cookie = id  + escape(value);

}

var grade=new Array()

function gradeit(){
if(document.getElementById('correctOne').checked)
    {
      right++;
      addToCookie("Q1 - Correct",right);
    }
    else {addToCOokie("Q1 - Incorrect", right);}
}


function checkCookie() {
var firstName = document.getElementById("fname").value;
var lastName = document.getElementById("lname").value;
var email =  document.getElementById("email").value;

    addToCookie("First Name= ",firstName);
    addToCookie("Last Name= ",lastName);
    addToCookie("Email=",email);
 }

window.onload = function () {
var elem = document.getElementById("submit");
elem.addEventListener('click', checkCookie);
}

// determine whether there is a cookie
var allcookies = document.cookie;
alert("All Cookies : " + allcookies);
// Get all the cookies pairs in an array
cookiearray = allcookies.split(';');

var result = "";

// Now take key value pair out of this array
for (var i = 0; i < cookiearray.length; i++) {
  name = cookiearray[i].split('=')[0];
value = cookiearray[i].split('=')[1];
result +=( name + " is : " + value)+"<br>";


 }
document.writeln(result);

Answer 1

我只是通过这种方式修改我的gradeit（）函数来实现它：

function gradeit(){
var ans = "";
if(document.getElementById('correctOne').checked)
    {
      //document.getElementById("output").innerHTML = "Q1 - Correct";
      right++;
      ans ="Right";
      addToCookie("Q1 - ", ans);
    }
    else {
        ans ="Wrong";
        addToCookie("Q1 - ", ans);
        }
}

Javascript添加cookie
