React實現(xiàn)點擊切換組件效果

這篇文章主要為大家詳細介紹了如何基于React實現(xiàn)點擊切換組件效果，文中的示例代碼講解詳細，具有一定的借鑒價值，需要的小伙伴可以學習一下

實現(xiàn)如下組件

組件代碼：

import { SwapOutlined } from "@ant-design/icons"
import React, { useState } from "react"
import './index.less'
interface ISwitchTypeProps {
  onChange?: (val) => boolean
  activeKey?: string
  left: { key: string, text: string }
  right: { key: string, text: string }
}
const SwitchType = ({ onChange, left, right, activeKey }: ISwitchTypeProps) => {
  const [data, setData] = useState({
    left,
    right,
    activeKey:activeKey||left.key
  })
  const changeActiveData = () => {
    const activeKey = data.activeKey === left.key ? right.key : left.key
    const changeData = () => {
      setData({
        left: { ...data.right },
        right: { ...data.left },
        activeKey
      })
    }
    if (onChange&&onChange(activeKey)) {
      changeData()
    }
    if (!onChange) {
      changeData()
    }
  }
  const changeActive = () => {
    const activeKey = data.activeKey === left.key ? right.key : left.key
    const changeData = () => {
      setData({
        ...data,
        activeKey
      })
    }
    if (onChange&&onChange(activeKey)) {
      changeData()
    }
    if (!onChange) {
      changeData()
    }
  }
  return <div className="switch-type">
    <div className={data.activeKey === data.left.key ? 'type-active' : 'type-data'} onClick={changeActive} key={data.left.key}>{data.left.text}</div>
    <div className="change-icon" onClick={changeActiveData}><SwapOutlined /></div>
    <div className={data.activeKey === data.right.key ? 'type-active' : 'type-data'} onClick={changeActive} key={data.right.key}>{data.right.text}</div>
  </div>
}
export default SwitchType

index.less樣式文件

.switch-type {
  display: flex;
  align-items: center;
  color: #B9BCC1;
  .change-icon {
    border-radius: 2px;
    background-color: #F1F3F5;
    width: 24px;
    height: 24px;
    line-height: 24px;
    text-align: center;
    flex-shrink: 0;
    margin: 0 8px;
    color: #555961;
    cursor: pointer;
  }
  .type-data {
    cursor: pointer;
  }
  .type-active {
    color: #555961;
    .type-data
  }
}

若想要實現(xiàn)如上效果，點擊不切換左右順序，只切換選中項，把onClick事件統(tǒng)一成changeActive就可以了

import { SwapOutlined } from "@ant-design/icons"
import React, { useState } from "react"
import './index.less'
interface ISwitchTypeProps {
  onChange?: (val) => boolean
  activeKey?: string
  left: { key: string, text: string }
  right: { key: string, text: string }
}
const SwitchType = ({ onChange, left, right, activeKey }: ISwitchTypeProps) => {
  const [data, setData] = useState({
    left,
    right,
    activeKey: activeKey || left.key
  })
  const changeActive = () => {
    const activeKey = data.activeKey === left.key ? right.key : left.key
    const changeData = () => {
      setData({
        ...data,
        activeKey
      })
    }
    if (onChange && onChange(activeKey)) {
      changeData()
    }
    if (!onChange) {
      changeData()
    }
  }
  return <div className="switch-type">
    <div className={data.activeKey === data.left.key ? 'type-active' : 'type-data'} onClick={changeActive} key={data.left.key}>{data.left.text}</div>
    <div className="change-icon" onClick={changeActive}><SwapOutlined /></div>
    <div className={data.activeKey === data.right.key ? 'type-active' : 'type-data'} onClick={changeActive} key={data.right.key}>{data.right.text}</div>
  </div>
}
export default SwitchType
