Question

这里我有用于表单验证的NodeJS代码，我正在处理。我不能让它重置用户输入的值。

验证没有做任何事情，我只是想用用户提供的值重置输入表单的值。有人请帮助我。

以下是代码：

注册路线：

var express = require('express');
var router = express.Router();

router.get('/', function(req, res, next) {

    var vm = {
    title: 'Join us now,  Brovis'
    };
  res.render('signup', vm);
});

router.post('/', function(req, res, next) {
  var flagChecker= true;
  if (flagChecker) {
    var vm = {
      title: 'Create an account',
      input: req.body,
      error: 'Something went wrong, Brovis'
    };
    delete vm.input.password;
    return res.render('signup', vm);
  }
  res.redirect('/');
});
module.exports = router;

注册的index.hbs：

<link rel="stylesheet" href="css/silog.css">
 <div class="jumbotron">
                 <div class="container">
                 <div class = "row">
                 <div class = "col-md-6 theForm">
                        <div class="form-box">
                            <div class="form-top">
                                    <h2>Sign up now</h2>
                                    <p>Join the community now:</p>
                                </div>
                            </div>
                            <div class="form-bottom">
                                <form role="form" action="" method="post" class="registration-form">
                                    <div class="form-group">
                                        <label class="sr-only" for="firstname">First name</label>
                                        <input type="text" name="form-first-name" placeholder="First name" class="form-first-name form-control" id="form-first-name" required value = "{{input.firstname}}">
                                    </div>
                                    <div class="form-group">
                                        <label class="sr-only" for="password">Last name</label>
                                        <input type="text" name="form-last-name" placeholder="Last name..." class="form-last-name form-control" id="form-last-name" required value = {{input.password}}>
                                    </div>
                                    <button type="submit" class="btn">Sign me up!</button>
                                </form>
                          </div>
                        <span style = "color:red; font-weight: 600">{{error}}</span>
                </div>      
            </div>
        </div>

Answer 1

嗯，您的输入名称/ ID是form-first-name，但是因为您使用了firstname而不是form-first-name;用户提供的值未被重置。替换为：

<input type="text" name="form-first-name" placeholder="First name" class="form-first-name form-control" id="form-first-name" required value = "{{input.form-first-name}}">

此外，您在第二个输入字段中错过了引号。它应该是：

<input type="text" name="form-last-name" placeholder="Last name..." class="form-last-name form-control" id="form-last-name" required value = "{{input.form-last-name}}">

这样可行。

干杯。
