Question

我将数据插入mongodb，然后将页面渲染到success.ejs。在success.ejs文件中，我给了一个链接。当在同一个success.js文件中单击链接时，应该从mongodb获取数据并显示在相同的success.ejs文件中。但在加载success.ejs文件之后，在控制台中发布数据后显示holedata未定义错误消息。

我在index.js文件中的帖子数据部分

＆＃13;

app.post('/signingin', function(req, res) {
      var item = {
        name: req.body.name,
        title: req.body.title,
        age: req.body.age
      };
      mongo.connect(url, function(err, db){
        assert.equal(null, err);
        db.collection('satyamsoft').insertOne(item, function(err, result){
          assert.equal(null, err);
          console.log('item inserted');
          db.close();
        });
      });
        res.render('pages/success');
        //console.log(req.body);
    });

＆＃13;

我的成功。页面

＆＃13;

!DOCTYPE html>
<html lang="en">

    <% include ../partials/head %>
    <title>Post Jobs | Spyeer</title>
    <body>

        <% include ../partials/nav %>       
        <section class="get">
          <h2>Data Inserted</h2>
          <a href="/getdata">Get Data</a>
          <div>
            <ul>
                <% holedata.forEach(function(data) { %>
                    <li><%= data.this.name %> - <%= data.this.title %> - <%= data.this.age %></li>
                <% }); %>
            </ul>
          </div>
        </section>

        <% include ../partials/footer %>

        <% include ../partials/scripts %>

    </body>
</html>

＆＃13;

获取index.js文件中的部分代码

＆＃13;

app.get('/getdata', function(req, res){
      var resultArray = [];
      mongo.connect(url, function(err, db){
        assert.equal(null, err);
        var cursor = db.collection('satyamsoft').find();
        cursor.forEach(function(doc, err){
          assert.equal(null, err);
          resultArray.push(doc);
          //console.log(resultArray);
        //res.render('pages/getdata', {holedata: resultArray});
      }, function(){
        db.close();
        res.render('pages/success', {holedata: resultArray});
      });

＆＃13;

请帮我提前谢谢。

你只需要检查每次页面渲染时应该 holedata 为空或者使用数据而不是{ "user": [{ "cdb_id":"", "firstname":"Tom", "lastname":"Bradley", "phone":14155555555, "email":"tom@gmail.com", "address":[{ "street":"4343 shoemaker ave", "city":"Brea", "zip":"92821", "country":"USA" }], "authenticators":[{ "name":"Lisa Hayden", "phone":15625555555 },{ "name":"Pavan M", "phone":17145555555 }], "voice_sig":"242y5-4546-555kk54-437879ek545", "voicesig_created_time":"2017-08-02T21:27:44+0000", "status":"verified" }] }你应该写res.render('pages/success');

在res.render
