redux-form正在刷新页面onSubmit

我有一个redux表单，提交后会导致整个浏览器页面刷新，这是不希望的...

I have a redux form that when submitted, is causing the entire browser page to refresh which is not desired...

我在做什么错，导致页面在提交时刷新?

What am I doing wrong here to cause the page to refresh on submit?

Rate.js

import React from 'react';
import RateForm from '../../components/rate/RateForm';

class Rate extends React.Component {

  handleSubmit(data) {
    alert('x')
    console.log('handleSubmit');
    console.log(data);
  }

  render() {

    const fields = [
          {
            name: 'execution',
            type: 'select',
            options: [
              { label: '5', value: '5' },
            ],
          },
        ]

    return (
      <div>
        <RateForm fields={fields} handleSubmit={this.handleSubmit.bind(this)} />

      </div>
    )
  }

export default Rate;
