我与Node JS上的数据库具有odbc连接。
var express = require('express');
var odbc = require('odbc');
var app = express();
var connectionString = 'Dsn=xxx;uid=xxx;pwd=xxx';
app.get('/query/:table', function (req, res) {
var table = req.params.table;
//console.log('User is accessing : ' + table);
var connection = odbc.connect(connectionString, (error, connection) => {
connection.query("SELECT * FROM " + table + "", (error, result) => {
if (error) { console.error(error) }
var json = JSON.stringify(result);
res.send(json);
});
});
});
app.get('/', function (req, res) {
res.sendFile(__dirname + '/index.html');
});
app.listen(80, function () {
console.log('Application listening on port 80');
});
在localhost / query / colli上，我的输出是：
[{“ MATRK1：” 0000019863“，” FLG1K1“：” S“}，{” MATRK1“：” 0000019864“，” FLG1K1“：” S“}]（以及更多行）
我的index.html看起来像这样：
<script src="https://code.jquery.com/jquery-3.4.1.slim.js"
integrity="sha256-BTlTdQO9/fascB1drekrDVkaKd9PkwBymMlHOiG+qLI="
crossorigin="anonymous"></script>
<script>
function getElement(id) {
return document.getElementById(id);
}
fetch('http://localhost/query/colli')
.then(res => res.json())
.then((res) => {
const data = res;
document.write(data)
getElement('name').innerHTML = 'Name: ' + data;
});
</script>
<div>
<p id="name"></p>
</div>
<body>
</body>
但是我正在接收：
[[对象对象]，[对象对象]结果
我在做什么错？我想从Node提取数据到HTML。
非常感谢您的时间：）
由于data是JSON对象，因此您无法执行getElement('name').innerHTML = 'Name: ' + data;。您将必须从对象中获取一个特定的键，以得到您想要的值。
我从console.log（data）的当前输出
(1554) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, …]
[0 … 99]
0: {MATRK1: "0000019863", FLG1K1: "S"}
1: {MATRK1: "0000019864", FLG1K1: "S"}
2: {MATRK1: "0000019865", FLG1K1: "S"}
3: {MATRK1: "0000019866", FLG1K1: "S"}
取决于您的console.log，调用get方法
尝试运行此代码console.log(data.get())
