将变量从ejs或javascript（浏览器）文件获取到Express
[英]Get the variable from ejs or javascript(browser) file to the Express
问题描述
How do I take a value from ejs or javascript file to ExpressJS ? 
如何从ejs或javascript文件中获取一个值给ExpressJS？ I have ejs and javascript files in my project. 我的项目中有ejs和javascript文件。 Both of these files have the same variable, so I need to find a way to get that variable from one of them. 这两个文件具有相同的变量，因此我需要找到一种从其中一个变量中获取该变量的方法。 Problem is, when I try to import ejs file, I get syntax errors because ejs file has HTML tags such as div, body, script, etc. For the Javascript file, it has 18,000 lines and it was written for browsers. 问题是，当我尝试导入ejs文件时，由于ejs文件具有HTML标签（例如div，body，script等），因此出现语法错误。对于Javascript文件，它有18,000行，是为浏览器编写的。 Meaning, I get thousands of errors like window is not defined , blabla is not a function , x is not defined , etc. 意思是，我得到成千上万的错误，例如未定义window ， blabla不是函数 ， x未定义等。
I tried to export them with module.exports, when I try to import it on server file like 'const example = require('./x/index.ejs)' then I get the errors for both of the files. 我尝试使用module.exports导出它们，当我尝试将其导入服务器文件（例如'const example = require('./x/index.ejs)'我得到了两个文件的错误。
// The thing that I want an example
// Server side
const x = require('./x/file)'
app.get('/havaist/live', (req, res) => {
console.log(x.theWantedVariable)
})
// Ejs
<body>
<div> <h1> Hey there. </h1> </div>
<script>

从ejs文件发送ajax POST请求，并从express文件中获取该值。
