ReactJS ajax响应错误呈现在组件中

我想在我的'FormError'组件中ajax调用后呈现json响应错误。

我的错误组件是这样的:

var FormError = React.createClass({
    render: function () {
        return (
            <span className="form-error"></span>
        );
    }
});

我的形式:

var EmailForm = React.createClass({
    getInitialState: function(){
      return {
          password:'',
          email: ''
      };
    },
    componentDidMount: function() {
        this.serverRequest = $.get('/accounts/email-form/', function (result) {
          var userInfo = result;
          this.setState({
            email: userInfo.email
          });
        }.bind(this));
    },
    submit: function (e){
      var self;
      e.preventDefault()
      self = this;
      console.log(this.state);
      var data = {
        password: this.state.password,
        email: this.state.email,
        CSRF: csrftoken
      };
      // Submit form via jQuery/AJAX
      function csrfSafeMethod(method) {
            // these HTTP methods do not require CSRF protection
            return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
      }
      $.ajaxSetup({
            beforeSend: function(xhr, settings) {
                if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                    xhr.setRequestHeader("X-CSRFToken", csrftoken);
                }
            }
      });
      $.ajax({
        type: 'POST',
        url: '/accounts/email-form/',
        data: data
      })
      .done(function(data) {
        toastr.success('Profile updated');
      })
      .fail(function(jqXhr) {
        toastr.error('There is some errors in your request');
      });
    },
    passwordChange: function(e){
      this.setState({password: e.target.value});
    },
    emailChange: function(e){
     this.setState({email: e.target.value});
    },
    render: function() {
        return (
            <form onSubmit={this.submit}>
                <div className="form-half">
                    <label htmlFor="password" className="input-label">Current Password</label>
                    <BasicInputPassword valChange={this.passwordChange} val={this.state.password}/>
                    <FormError/>
                </div>
                <div className="form-half">
                    <label htmlFor="lastname" className="input-label">New email</label>
                    <BasicInput valChange={this.emailChange} val={this.state.email}/>
                    <FormError/>
                </div>
                 <button type="submit" className="button secondary" >Submit</button>
            </form>
        );
    }
});

这个代码工作，ajax调用给我响应json与错误

{"email":["Email already exists."],"password":["This field may not be blank."]}

但是我不知道如何将这个错误附加到我的代码和我的react组件。
