I am hosting a personal website that uses p5.js. 我正在托管一个使用p5.js的个人网站。 The problem is I need to send the variables to the server so that whenever I access the website it saves my data. 问题是我需要将变量发送到服务器，以便每当我访问该网站时它都会保存我的数据。 Lets just call the variable that i want to save "test". 让我们只调用我要保存的变量“测试”。 Test's value is 3, and I want it to stay at 3 next time I access it. 测试的值是3，我希望下次访问它时该值保持在3。 And I can change test's value to 5, but its value stays 0 when I refresh the page (int test = 0) Thanks for helping out! 而且我可以将test的值更改为5，但刷新页面时它的值保持为0（int test = 0），谢谢您的帮助！

You don't need to send variables to the server to do this. 您无需将变量发送到服务器即可执行此操作。 You could just use cookies. 您可以只使用Cookie。 Googling something like "JavaScript cookies" will give you a ton of results. 谷歌搜索“ JavaScript cookie”之类的东西将为您带来大量结果。 I personally use this library , but you can easily write your own code that saves and loads cookies (in fact, if you don't really understands how cookies work, this is a good way to learn!). 我个人使用该库，但是您可以轻松编写自己的代码来保存和加载cookie（实际上，如果您不太了解cookie的工作原理，这是学习的好方法！）。

The only reason you'd need to send something to the server is if you needed the values to persists for a user between different computers. 您需要将某些内容发送到服务器的唯一原因是，如果您需要这些值在不同计算机之间对于用户而言持久存在。 This would require a login of some kind (not to mention code running on a server), and is a lot more work than just using a cookie. 这将需要某种形式的登录（更不用说在服务器上运行的代码了），并且比仅使用cookie要做更多的工作。 But if you really need to go this route, googling something like "JavaScript post" or "JavaScript ajax" will return a bunch of promising results. 但是，如果您真的需要走这条路，那么搜索诸如“ JavaScript post”或“ JavaScript ajax”之类的东西将返回很多有希望的结果。 Of course, what you do with that information on the server is an entire project in itself. 当然，您在服务器上处理这些信息本身就是一个整个项目。
