如何使用 nodejs 创建 table 个车把

Question

伙计们，我有以下json server.js：

const express = require("express")
const app = express()                         
const http = require('http').Server(app);     
const sqlite3 = require('sqlite3').verbose(); 
const db = new sqlite3.Database('./conta.sql') 
const handlebars = require("express-handlebars");
const bodyParser = require("body-parser")                                                   

app.use(express.static(__dirname + "/css/"));   
                                        
app.use(bodyParser.urlencoded({extended:true}));
                                        
app.engine('handlebars', handlebars({defaultLayout:false}));                                
app.set('view engine', 'handlebars');         

function getallusers(req,res) {          
 try{     
  data = [
   { 
    id: 1,
    nome: 'Ronnica Hardison',
    data: '2021-09-31 04-54-00',
    email: 'test@gmail.com',
    nome_bonus: 'John Watson',
    cod_bonus: 'piwi20k9'
   },
   {
    id: 2,
    nome: 'Kellie Jean Abernethy',
    data: '2021-09-31 23-50-00',
    email: 'gobirob190@mnqlm.com',
    nome_bonus: 'Ámelia Barton',
    cod_bonus: 'piwiki20k9'
   }
  ]
  res.render(__dirname + "/index.handlebars")
 }
 catch(err){
  console.log("\x1b[31m Problema ao carregar as informações do banco de dados!",err);
 }
}
app.get('/', function(req,res){                
 getallusers(req,res)                         
});                                                                                         

http.listen(8083,() => {                       
 console.log("Servidor escutando na porta 8083");                                           
});

index.handlebars:

<center>
 <div class="table">                    
  <table cellspacing="0">                        
   <thead>
    <tr class="indices">
     <th>Nome</th>
     <th>Email</th>                                
     <th>Data de Criação</th>
     <th>Convidada de</th>                         
     <th>Codico usado</th>
     <th>Status</th>                              
    </tr>                                        
   </thead>
   <tbody>                                        
    <tr>                                                                      
     {{data here}}
    </tr>
   </tbody>
  </table>
 </div>
</center>

伙计们...我需要做的是在 table 中呈现 json 数据，我该怎么做？我需要的是根据 json 信息创建 <th> 标签，但这必须是动态的。 json 信息可能不同，即它是动态的，那么我该如何呈现呢？

试试这个：

在您的 server.js 中将数据传递到 index.handlebars 文件：

res.render(__dirname + "/index.handlebars",{data})

在index.handlebars中使用这个

<center>
 <div class="table">                    
  <table cellspacing="0">                        
   <thead>
    <tr class="indices">
     <th>Nome</th>
     <th>Email</th>                                
     <th>Data de Criação</th>
     <th>Convidada de</th>                         
     <th>Codico usado</th>
     <th>Status</th>                              
    </tr>                                        
   </thead>
   <tbody>                                        
    {{#each data}}
    <tr>
      <th scope="row">{{this.id}}</th>
      <td>{{this.nome}}</td>
      <td>{{this.email}}</td>
      <td>{{this.nome_bonus}}</td>
      <td>{{this.cod_bonus}}</td>
    </tr>
    {{/each}}
   </tbody>
  </table>
 </div>
</center>
