我想用node.js webserver在动态创建的html页面的标题中执行javascript文件。无法弄清楚如何但必须是可能的。
var http = require('http');
var url = require('url');
function processRequest(request, response) {
"use strict";
var pathname = url.parse(request.url).pathname;
console.log('Requested ' + pathname);
response.writeHead(1000, { 'Content-Type': 'text/html' });
response.write('<!DOCTYPE html><html ><head>');
response.write('<meta charset="utf-8">');
response.write('<title>' + 'Yay Node!' + '</title>');
response.write('<link rel=stylesheet href=../styles/styles.css rel=stylesheet />');
response.write('<script src=script.js type=text/javascript></script>');
response.write('</head><body>');
response.write('<h1><tt>' + 'jan' + '</tt></h1>');
response.write('<script type="text/javascript">test()</script>')
//response.write('<script type="text/javascript">script.onload = function () { alert("from html Node!")}; </script>')
response.write('<input id="clickMe" type="button" value="clickme" onclick="test()" />')
response.write('</body></html>');
response.end();
};
http.createServer(processRequest).listen(8888);
的script.js：
document.onload = function () { alert('load Node!'); };
test = function() { alert('test Node!') };
问题是，你的浏览器找不到script.js
当它试图使用与http://localhost:8888/script.js相同的html文件获取http://localhost:8888/节点答案时。
为了使节点能够正确地提供脚本文件，您需要检查路径并发送正确的文件。
在你的processRequest函数中添加这样的东西
if (pathname === '/script.js') {
//code to send script
} else {
//code to send html
}
你也必须为styles.css文件做同样的事情
如果您不想对页面中的每个文件进行硬编码，我建议使用npm模块express
var express = require('express'),
app = express(),
server = require('http').createServer(app);
app.use('/', express.static(__dirname + '/static');
server.listen(8888);
当浏览器请求时，此代码将自动发送/static中的文件。如果你想创建一个动态页面，你可以在app.use和server.listen之间添加它
app.all('/somedynamicurl', function (request, response) {
//Dynamic page
});
现在，如果有人去http://localhost:8888/somedynamicurl他们会得到这个动态页面。
我还建议阅读express guide和express docs
这很有效。感谢Ferdi265。
