我有多个选择元素，我用一个按钮提交它们。这是一个例子:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<title>Page Title</title>
<meta name='viewport' content='width=device-width, initial-scale=1'>
</head>
<body>
<div class="inner">
<form method="POST" action="test">
<label name="first">first</label>
<select style="display:inline-block">
<option value="value1" name ="value1">test 1 </option>
<option value="value2" name= "value2">test 2</option>
</select>
<label name="second">second</label>
<select style="display:inline-block">
<option value="4">1</option>
<option value="5">2</option>
<option value="6">3</option>
<input type="submit" value="Submit" class="button" >
</form>
</div>
</body>
</html>
我正在尝试使用nodejs来处理它们并表达如下:
const express = require('express');
const app = express()
var path = require('path')
var fs = require('fs')
app.use(express.static('public'))
app.use(express.urlencoded())
console.log(__dirname)
app.get('/',function(req,res){
res.sendFile(path.join(__dirname+'/index.html'))
})
app.post('/test', (req, res) => {
console.log(req.body.value1)
})
app.listen(2000)
显然这是不正确的，所以我的问题是我该怎么做？
提前致谢!

我认为你在编写 html 时犯了错误。 首先，您必须向选择框添加名称属性，以便您可以在服务器端使用值。 其次，您没有关闭第二个选择元素。
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<title>Page Title</title>
<meta name='viewport' content='width=device-width, initial-scale=1'>
</head>
<body>
<div class="inner">
<form method="POST" action="test">
<label name="first">first</label>
<select style="display:inline-block" name='select_box_1'>
<option value="value1" name ="value1">test 1 </option>
<option value="value2" name= "value2">test 2</option>
</select>
<label name="second">second</label>
<select style="display:inline-block" name="select_box_2">
<option value="4">1</option>
<option value="5">2</option>
<option value="6">3</option>
</select>
<input type="submit" value="Submit" class="button" >
</form>
</div>
</body>
</html>
