    res.cookie("cookie_email_id", req.body.email);

And I have check My Cookie in console cookie is set

推荐答案

要通过ejs预填充表单输入，首先需要通过res.cookie()设置cookie.要在表单字段中自动填充这些值.您需要从请求中获取Cookie并将其分配给您的render方法.

To pre-fill form inputs through ejs, first of all you need to set the cookies via res.cookie() .To autofill these values in a form field .You need to get the cookies from the request and assign it to your render method.

为此，您可以使用这样的cookie解析器中间件，并在req.cookies/req.signedCookies中获取cookie值.

For this you can use cookie-parser middleware like this and get the cookie values in req.cookies/req.signedCookies.

var express = require('express')
var cookieParser = require('cookie-parser')

var app = express()
app.use(cookieParser())

app.get('/', function (req, res) {
  // Cookies that have not been signed
  console.log('Cookies: ', req.cookies)

  // Cookies that have been signed
  console.log('Signed Cookies: ', req.signedCookies)
})

app.listen(8080)

从路由中，您可以调用具有所有要自动填充的属性的ejs渲染方法

From the route you can call your ejs render method with all the properties to autofill

类似

res.render('user_profile',{name:req.cookies.name, age:req.cookies.age})

然后您可以将值放置在ejs表单字段中，例如

You can then place the values in your ejs form fields as like

<input type="text" id="name" value="%name%"/>
<input type="text" id="age" value="%age%"/>
