我第一次使用javascript并尝试通过cookie将变量传递到另一个页面。然而，它似乎并没有起作用。现在我只是尝试使用警告框检查cookie值。我看过，但是找不到任何可以帮助我弄清楚出了什么问题的东西。我最初尝试从此页面实施解决方案：How to use JavaScript to fill a form on another page
感谢任何帮助。
我的第一页代码是：

另外，由于某种原因，firefox web控制台似乎认为我需要在quest5之后的第一页放置一个分号：
document.cookie=name + "," + quest1 + "/" + quest2 + "/" + quest3 + "/" + quest4 + "/" + quest5 "/" + quest6 + "/" + quest7 + "/" + commentline + "; path=/lab5summary.html";
作为最后一点，我只能使用javascript，而不是jQuery或PHP。
答案 0 :(得分：2)
在您的示例中缺少加号：
+ quest5的 + "/" + quest6
Cookie受域绑定，因此如果您从文件系统（例如file：//index.html）打开，则无法使用。
如果您使用的是现代浏览器，我建议您使用localStorage和sessionStorage。 只要页面打开并且localStorage，就会持续sessionStorage，直到清理浏览器的缓存为止。
答案 1 :(得分：0)
您也可以使用store.js Store.js
你也可能希望通过使用id和变量的对象和数组来表示你的代码。
