我有每隔几分钟返回新数据的API。我需要的是自动创建新的div并将数据添加到其中。
当前，我能够在浏览器中显示初始数据。但是它应该每两分钟添加一次新的div和新数据。
app.js
var express = require('express');
var router = express.Router();
var request = require("request");
let name, value, bodyData;
var options = { method: 'GET',
url: 'https://api.example.com/data1',
qs:
{
valueType: 'MAXIMUM'
},
headers:
{
authorization: 'ABC123456',
accept: 'application/json; charset=utf-8' } };
request(options, function (error, response, body) {
if (error) throw new Error(error);
bodyData1 = JSON.parse(body);
name = bodyData.name;
value = bodyData.value;
});
router.get('/', function(req, res, next) {
res.render('home', {names: name, values : value});
});
module.exports = router;
app.ejs
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<body>
<div class="itemsList">
<h2>List of available items: </h2>
<div>Name: <%= names %> Value: <%= values %><div>
</div>
<script src="/scripts.js">
//var newDiv = document.createElement("div");
//newDiv.innerHTML = "Name: ${names} Value: ${values}";
//document.body.appendChild(newDiv);
</script>
</body>
</html>
scripts.js
var newDiv = document.createElement("div");
newDiv.innerHTML = "Name: ${names} Value: ${values}";
document.body.appendChild(newDiv);
[您可以通过在app.js中添加创建div的代码来尝试
request(options, function (error, response, body) {
if (error) throw new Error(error);
bodyData1 = JSON.parse(body);
let name = bodyData.name;
let value = bodyData.value;
let newDiv = document.createElement("div");
newDiv.innerHTML = "Name: ${names} Value: ${values}";
document.body.appendChild(newDiv);
});
