我有此代码：
let http = require('http');
let fs = require('fs');
let handleRequest = (request, response) => {
response.writeHead(200, {
'Content-Type': 'text/html'
});
fs.readFile('./index.html', null, function (error, data) {
if (error) {
response.writeHead(404);
respone.write('Whoops! File not found!');
} else {
response.write(data);
}
response.end();
});
};
http.createServer(handleRequest).listen(8000);
[基本上，此代码在Node上创建本地服务器，然后打开文件：'index.html'。现在，我在'index.html'上创建一个<button>，单击（onclick）时会调用一个名为'hello'的函数：
function hello() {
console.log('hello world);
}
因此，当单击按钮时，浏览器控制台中将显示一个“ hello world”，但我希望在nodejs控制台而不是浏览器中显示“ hello world”。我该如何实现？谢谢！
您可以使用nodeJS和expressJS实现它。要安装快速运行npm i express。
尝试一下
let http = require('http');
let fs = require('fs');
let express = require('express');
let app = express();
app.get('/', function (req, res) {
res.sendfile('./index.html');
})
app.get('/getData', function (req, res) {
console.log("getData called.");
res.send("res from getData function");
})
var server = app.listen(8000, function () {
var host = server.address().address
var port = server.address().port
console.log("Example app listening at http://%s:%s", host, port)
})<html>
<head>
<script>
function httpGet(theUrl) {
var xmlhttp = new XMLHttpRequest();
var url = "http://localhost:8000/getData";
xmlhttp.onreadystatechange = function (res) {
if (this.readyState == 4 && this.status == 200) {
document.write(this.responseText);
}
};
xmlhttp.open("GET", url, true);
xmlhttp.send();
}
</script>
</head>
<body>
<button onclick="httpGet()">httpGet</button>
</body>
</html>
