Reactでinput type=fileのフォームを作っていい感じにスタイルする

Last updated at Posted at 2019-03-30

input要素って、typeがfileになると途端にスタイルが面倒くさくなりますよね。
reactでそれっぽいコンポーネントを作ったので、残しておきます。

import React, { useState } from 'react';
import styled from 'styled-components';

const Wrapper = styled.div`
  display: flex;
`;
const Label = styled.label`
  お好きにどうぞ
`;
const Input = styled.input`
  display: none;
`;
const FileName = styled.p`
  お好きにどうぞ
`;

const onChange = (event, cb, setFileName) => {
  cb(event);
  const targetName = event.target.files.item(0).name;
  setFileName(targetName);
};

const InputFile = props => {
  const [filename, setFileName] = useState('選択されていません');
  if (props.type !== 'file') return <p>typeの指定、間違ってるよ</p>;
  return (
    <Wrapper>
      <Label>
        ファイルを選択
        <Input
          {...props}
          onChange={e => onChange(e, props.onChange, setFileName)}
        />
      </Label>
      <FileName>{filename}</FileName>
    </Wrapper>
  );
};

export default InputFile;

使い方はこんな感じ

<InputFile
  type='file'
  accept='image/*'
  onChange={e => なんか好きな処理}
/>
