使用cookie传递变量到另一个页面
javascript Using cookie to pass variables to another page
我第一次使用javascript，我试图通过cookie将变量传递到另一个页面。然而，它似乎并没有起作用。现在我只是试图检查cookie值使用一个警告框。我已经看过了，但还没有找到任何可以帮助我找出问题所在的东西。我最初试图从这个页面实现解决方案:如何使用JavaScript在另一个页面上填写表单
任何帮助都是感激的。
第一页的代码是:

此外，由于某些原因，firefox web控制台似乎认为我需要在第一页的quest5:
后面放置一个分号。document.cookie=name + "," + quest1 + "/" + quest2 + "/" + quest3 + "/" + quest4 + "/" + quest5 "/" + quest6 + "/" + quest7 + "/" + commentline + "; path=/lab5summary.html";
最后需要说明的是，我只能使用javascript，不能使用jQuery或PHP。
在你的例子中缺少一个加号:
+ quest5 + "/" + quest6
cookie是由一个域绑定的，所以如果你从你的文件系统(例如file://index.html)打开，它将无法工作。
如果你在现代浏览器上，我建议你使用localStorage和sessionStorage。sessionStorage持续到页面打开，localStorage持续到浏览器的缓存被清理。
你也可以使用store.jsStore.js
并且您可能还想通过使用对象和数组来删除id和变量。
