在React.js中创建我的第一个应用程序,并希望使用Ajax将联系表单提交到电子邮件中。我已将此解决方案用作准则:https : //liusashmily.wordpress.com/author/liusashmily/,但完整的组件文件不可用,只有部分内容,我无法联系作者。
// Create Component class Contact extends React.Component { constructor(props){ super(props); this.state = { contactEmail: '', contactMessage: '' }; this.handleSubmit = this.handleSubmit.bind(this); this.handleChange = this.handleChange.bind(this); this.handleChangeMsg = this.handleChangeMsg.bind(this); } handleChange(event) { this.setState({ contactEmail: event.target.value, }); } handleChangeMsg(event) { this.setState({ contactMessage: event.target.value }); } handleSubmit(event) { event.preventDefault(); this.setState({ type: 'info', message: 'Sending…' }); $.ajax({ url: 'php/mailer.php', type: 'POST', data: { 'form_email': this.state.contactEmail, 'form_msg': this.state.contactMessage }, cache: false, success: function(data) { // Success.. this.setState({ type: 'success', message: 'We have received your message and will get in touch shortly. Thanks!' }); }.bind(this), error: function(xhr, status, err) { this.setState({ type: 'danger', message: 'Sorry, there has been an error. Please try again later or visit us at SZB 438.' }); }.bind(this) }); } render() { return ( <div className="contact"> <form className="form" onSubmit={this.handleSubmit} id="formContact"> <label>Email</label> <input id="formEmail" type="email" name="formEmail" value={this.state.contactEmail} onChange={this.handleChange} required /> <label>Meddelande</label> <textarea id="formMsg" name="formMsg" rows="8" cols="40" value={this.state.contactMessage} onChange={this.handleChangeMsg} required></textarea> <input type="submit" value="Submit" className="btn--cta" id="btn-submit" /> </form> </div> ) } }
<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { // $name = strip_tags(trim($_POST[“form_name”])); // $name = str_replace(array(“\r”,”\n”),array(” “,” “),$name); $email = filter_var(trim($_POST["formEmail"]), FILTER_SANITIZE_EMAIL); $message = trim($_POST["formMsg"]); // Check that data was sent to the mailer. if ( empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) { // Set a 400 (bad request) response code and exit. http_response_code(400); echo "Oops! There was a problem with your submission. Please complete the form and try again."; exit; } // Set the recipient email address. $recipient = "[email protected]"; // Set the email subject. $subject = "New message from $email Via React Site"; // Build the email content. $email_content .= "Email: $email\n\n"; $email_content .= "Message: \n$message\n"; // Build the email headers. $email_headers = "From: <$email>"; // Send the email. if (mail($recipient, $subject, $email_content, $email_headers)) { // Set a 200 (okay) response code. http_response_code(200); echo "Thank You! Your message has been sent."; } else { // Set a 500 (internal server error) response code. http_response_code(500); echo "Oops! Something went wrong and we couldn’t send your message."; } } else { // Not a POST request, set a 403 (forbidden) response code. http_response_code(403); echo "There was a problem with your submission, please try again."; } ?>
在控制台日志中出现以下错误:
POST http:// localhost:8080 / php / mailer.php 404(未找到)
..并说错误在“ jquery-3.2.1.min.js:4”文件中。
我在HTML文档中包含jQuery脚本:
<!Doctype html> <html> <head> <meta charset="utf-8"> <meta http-equiv="x-ua-compatible" content="ie=edge"> <title></title> <!-- <link rel="stylesheet" href="dist/styles.css"> --> <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script> </head> <body> <div id="app"></div> <script src="dist/bundle.js"></script> </body> </html>
非常感谢任何输入!
我找到了解决方案。这是我的联系人组件:
import React, { Component } from 'react'; // Contact component render contact form class Contact extends React.Component { constructor(props){ super(props); this.state = { contactEmail: '', contactMessage: '' }; this._handleSubmit = this._handleSubmit.bind(this); this._handleChange = this._handleChange.bind(this); this._handleChangeMsg = this._handleChangeMsg.bind(this); } // Change state of input field so text is updated while typing _handleChange(e) { this.setState({ contactEmail: e.target.value, }); } // Change state of input field so text is updated while typing _handleChangeMsg(e) { this.setState({ contactMessage: e.target.value }); } _handleSubmit(e) { e.preventDefault(); this.setState({ contactEmail: '', contactMessage: '' }); $.ajax({ url: process.env.NODE_ENV !== "production" ? '/getMail' : "http://www.fransbernhard.se/magden/php/mailer.php", type: 'POST', data: { 'form_email': this.state.contactEmail, 'form_msg': this.state.contactMessage }, cache: false, success: function(data) { // Success.. this.setState({ contactEmail: 'success', contactMessage: '<h1>Kontakt skickad!</h1><p>Återkommer så fort som möjligt.</p>' }); $('#formContact').slideUp(); $('#formContact').after(this.state.contactMessage); console.log('success', data); }.bind(this), // Fail.. error: function(xhr, status, err) { console.log(xhr, status); console.log(err); this.setState({ contactEmail: 'danger', contactMessage: '<h1>Sorry det blev fel</h1><p>Försök gärna igen, eller mejla mig direkt på [email protected]</p>' }); console.log(this.state.contactEmail + this.state.contactMessage + 'fail'); }.bind(this) }); } render() { return ( <div className="contact" id="contact"> <div className="filter"> <form className="form" onSubmit={this._handleSubmit} id="formContact"> <label>Email</label> <input id="formEmail" type="email" name="formEmail" value={this.state.contactEmail} onChange={this._handleChange} required/> <label>Meddelande</label> <textarea id="formMsg" name="formMsg" rows="8" cols="40" value={this.state.contactMessage} onChange={this._handleChangeMsg} required></textarea> <input type="submit" value="Submit" className="btn--cta" id="btn-submit" /> </form> </div> </div> ) } } export default Contact;
mailer.php文件:
<?php // trim() function strips any white space from beginning and end of the string $email = filter_var(trim($_POST["form_email"]), FILTER_SANITIZE_EMAIL); // strip_tags() function strips all HTML and PHP tags from a variable. $message = strip_tags($_POST["form_msg"]); // Check that data was sent to the mailer. if ( empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) { // Set a 400 (bad request) response code and exit. http_response_code(400); echo "Oops! There was a problem with your submission. Please complete the form and try again."; exit; } // Set the recipient email address. $recipient = "[email protected]"; // Set the email subject. $subject = "Message to magdalundberg.se from: $email"; // Build the email content. $body .= "Email: $email\n\n"; $body .= "Message: \n$message\n"; // success $success = mail($recipient, $subject, $body, "From:" . $email); // Send the email. if ($success) { // Set a 200 (okay) response code. http_response_code(200); echo "Thank You! Your message has been sent."; } else { // Set a 500 (internal server error) response code. http_response_code(500); echo "Oops! Something went wrong and we couldn’t send your message."; } ?>
