Question

我有一个redux表单，在提交时会导致整个浏览器页面刷新，这是不希望的......

我在这里做错了什么导致页面在提交时刷新？谢谢！

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;

RateForm.js

import React from 'react';
import { Field, reduxForm } from 'redux-form';

const renderField = ({ input, field }) => {
  const { type, placeholder } = field
  if (type === 'text' || type === 'email' || type === 'number' || type === 'checkbox') {
    return <input {...input} placeholder={placeholder} type={type} />
  } else if (type === 'select') {
    const { options } = field
    return (
      <div>
        <label>{field.name}</label>
        <select name={field.name} onChange={input.onChange}>
          {options.map((option, index) => {
            return <option key={index} value={option.value}>{option.label}</option>
          })}
        </select>
      </div>
    )
  } else {
    return <div>Type not supported.</div>
  }
}

class RateForm extends React.Component {

  render() {
    return (
      <form onSubmit={this.props.handleSubmit}>
        {this.props.fields.map(field => (
          <div key={field.name}>
            <Field
              name={field.name}
              component={renderField}
              field={field}
              />
          </div>
        ))}
        <button type="submit">Submit</button>
      </form>
    )
  }

}

RateForm = reduxForm({
  form: 'rateForm'
})(RateForm);


export default RateForm;

Answer 1

您需要将handleSubmit函数作为处理程序传递给RateForm组件，引用名称为onSubmit。

使用此

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

Answer 2

内部File sdcard = Environment.getExternalStorageDirectory(); //Get the text file File file = new File(sdcard, "data.txt"); //Read text from file StringBuilder text = new StringBuilder(); try { BufferedReader br = new BufferedReader(new FileReader(file)); String line; while ((line = br.readLine()) != null) { text.append(line); text.append('\n'); } Log.d("Activity","Final Text----->"+text); br.close(); } catch (IOException e) { e.printStackTrace(); //You'll need to add proper error handling here }方法：

render

redux-form正在刷新页面onSubmit
