在React表单组件中输入文本不允许文本输入

我是一个很新的反应者,根据一个教程,我制作了这个注册表(我刚用Materialize更改了引导HTML)

import React, {Component} from 'react';

class Register extends Component {
    constructor() {
        super();
        this.state = {          
            email: '',
            password: '',
            errors: {}
        };

          this.handleChange = this.handleChange.bind(this);
    }

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

    render() {
        return (

        <div>
          <div className="row">
            <div className="col s10 m6 offset-s1 offset-m3 ">

                <form className="col s12 myform">
                <h3 className="center"Register </h3>
                        <div className="row">
                          <div className="input-field col s12">
                            <input 
                                id="email" 
                                type="email" 
                                value={this.state.email} 
                                onChange = {this.handleChange}
                                />
                            <label htmlFor="email">Email</label>
                          </div>
                        </div>

                       <div className="row">
                          <div className="input-field col s12">
                            <input 
                                id="password" 
                                type="password" 
                                value={this.state.password} 
                                onChange = {this.handleChange}  
                                />
                            <label htmlFor="password">Password</label>
                          </div>
                        </div>

                        <button className="btn mybtn waves-effect waves-light right" type="submit" name="action">Submit
                                <i className="mdi-content-send right"></i>
                              </button>
              </form>
            </div>  
          </div>    
        </div>



            );
    }
}

export default Register;

问题是我不能在表单中输入任何内容,并且在控制台中也没有得到任何错误。所以就提前准备好了。感谢你的提示。
