EmailJS：仅有时有效

Question

我正在使用 React 和 EmailJS 设计联系表单。我的问题是，当我为名称、电子邮件、Phone 或消息输入自己的值时，电子邮件不起作用。当我单击“发送消息”按钮而不在名称、电子邮件、Phone 或消息中输入任何内容（因此它使用默认值）时，它有时会起作用（通常不是在第一次单击按钮时，而是在第二次单击时).

我不确定如何解决这个问题，希望得到帮助！


export default class Contact extends React.Component {
    constructor(props) {
        super(props);
        this.state = { message: '', name: 'Name', email: 'Email', phone: 'Phone' };
        this.handleChange = this.handleChange.bind(this);
        this.handleSubmit = this.handleSubmit.bind(this);
      }

      handleChange(event) {
        this.setState({
          [event.target.name]: event.target.value
        });
    }

      handleSubmit (event) {
        var template_params = {
            "name": "name_value",
            "message": "message_value",
            "phone": "phone_value",
            "email": "email_value"
         }

         var service_id = "default_service";
         var template_id = <TEMPLATE_ID_FROM_EMAILJS_ACCOUNT>;
         window.emailjs.send(service_id, template_id, template_params).then(res => {
             console.log('MESSAGE SENT', res.status);
             alert("Message Sent!");
         }).catch(e => {
             console.log("There was an error", e);
         }); 
      }

    render() {

        return (

Answer 1

不确定，但您似乎没有阻止提交的默认行为，因此您的页面刷新，您的表单是新的，并且您的函数未被调用。尝试添加

event.preventDefault();

在 handleSubmit 函数的开头。

请点击link查看EmailJS邮件正文模板图片。

我遇到了类似的问题。您必须使用两个或三个大括号设置 emailJS 模板，就像您在 JSX 中输入名称（名称 =“名称”）一样。（如附图所示）我似乎有一些文档列出了两个或三个大括号，似乎两种方法都有效，但并非始终如此。（imo emailJS 似乎不一致。）您还必须确保在测试前“保存”模板设置。

 <input 
            type ="text" 
            className = "form-input"
            name ="name" 
            placeholder="Name"
            onChange ={updateForm} 
            value = {form.name}
        />
