我在服务器端呈现所有内容并触发handleSubmit时出现问题。这是源代码:
index.js:
module.exports = require('./app/server');
应用程序/服务器/ index.js:
'use strict';
var env = process.env.NODE_ENV || 'development';
var express = require('express');
var http = require('http');
var app = express();
app.set('state', {});
// Inject Config
require('../config/server')[env](app, express);
// Inject component rendering
require('node-jsx').install({extension: '.jsx'});
app.use(require('../../lib/renderReactComponent')(app));
// Start server
var server = http.createServer(app);
return server.listen(app.get('port'), function() {
return console.log('Listening on port ' + app.get('port') + ', Env: ' + app.settings.env);
});
module.exports = app;
LIB / renderReactComponent.js:
var ReactApp = require('../app');
var React = require('react');
var path = require('path');
var url = require('url');
module.exports = function(app) {
return function(req, res, next) {
try {
var path = url.parse(req.url).pathname;
res.send(React.renderComponentToStaticMarkup(ReactApp({path: path, state: app.get('state')})));
} catch(err) {
return next(err)
}
}
}
应用程序/ index.js:
var ReactApp = require('./components/app');
module.exports = ReactApp;
应用/组件/ app.js:
/**
* @jsx React.DOM
*/
var React = require('react');
var ReactRouter = require('react-router-component');
var App = React.createClass({
propTypes: {state: React.PropTypes.object.isRequired},
getInitialState: function() {
return {items: [], text: ''};
},
handleSubmit: function () {
console.log("handleSubmit triggered!");
var $author = this.refs.author.getDOMNode(),
$text = this.refs.text.getDOMNode(),
author = $author.value.trim(),
text = $text.value.trim();
if(!author || !text) {
return false;
}
if(this.props.onCommentSubmit) {
this.props.onCommentSubmit({ author: author, text: text });
}
$author.value = '';
$text.value = '';
return false;
},
render: function() {
return (
<html>
<form className="commentForm" onSubmit={this.handleSubmit}>
<input type="text" ref="author" placeholder="Your name"/>
<input type="text" ref="text" placeholder="Say Something ..."/>
<input type="submit" value="Post"/>
</form>
</html>
);
}
});
module.exports = App;
此代码不会给我一个错误,但不会触发handleSubmit。我认为这是因为它不是由服务器端呈现的。在尝试从服务器端渲染页面时,如何触发表单事件handleSubmit?
答案 0 :(得分:6)
流程的工作原理如下:
在handleSubmit中,如果您想将一些数据发送到服务器,您可以使用常规的AJAX / WebSockets / etc技术来完成。
