使用react-color实现前端取色器的方法
背景
我们可以通过react-color实现前端界面的取色器,效果如下图所示:
安装
npm i react-color -S
使用
import React, { Component, Fragment, createRef } from 'react'; import { Popover } from 'antd'; import { SketchPicker } from 'react-color'; type StateType = { subtitleColor: string; }; type PropType = { [propName: string]: any; }; interface HandleCreateVideoByHotNews { state: StateType; props: PropType; } class HandleCreateVideoByHotNews extends Component { constructor(props: any) { super(props); this.state = { subtitleColor: '#FFF', } } // 修改字幕字体颜色 private setSubtitleFontColor = (e: any): void => { console.log(e); this.setState({ subtitleColor: e.hex, }); } render() { const { subtitleColor } = this.state; return ( <Popover content={<SketchPicker color={subtitleColor} onChange={(e) => {this.setSubtitleFontColor(e)}} onChangeComplete={(e) => {this.setSubtitleFontColor(e)}} />} trigger="click" > <div className="create-hotnews-video-popup-operate-item-titleset-item-operate font-color-set"> <div className="font-color-set-value">{subtitleColor}</div> <div className="font-color-set-show" style={{backgroundColor: subtitleColor}}></div> </div> </Popover> ) } } export default HandleCreateVideoByHotNews;
