typescript+react实现移动端和PC端简单拖拽效果

本文实例为大家分享了typescript+react实现移动端和PC端简单拖拽效果的具体代码,供大家参考,具体内容如下

一、移动端

1.tsx代码

import { Component } from "react";
import './Tab.less'
interface Props {
 
}
interface user {
    id: string,
    text: string
}
interface content {
    id: string,
    text: string
}
interface State {
    ButtonIndex: number,
    ButtonArray: user[],
    ContentArray: content[]
}
class Tab extends Component{
    constructor(props: Props) {
        super(props)
        this.state = {
            ButtonIndex: 0,
            ButtonArray: [
                {
                    id: '01',
                    text: '按钮一'
                },
                {
                    id: '02',
                    text: '按钮二'
                },
                {
                    id: '03',
                    text: '按钮三'
                }
            ],
            ContentArray: [
                {
                    id: 'c1',
                    text: '内容一'
                },
                {
                    id: 'c2',
                    text: '内容二'
                },
                {
                    id: 'c3',
                    text: '内容三'
                }
            ],
        }
    }
    FnTab(index: number):void {
        this.setState({
            ButtonIndex: index
        })
    }
    render() {
        return (
            
{ this.state.ButtonArray.map((item, index) => ) } { this.state.ContentArray.map((item, index) =>
{item.text}
) }
) } } export default Tab

2.css代码

.drag {
    position: absolute;
    width: 100px;
    height: 100px;
    background-color: red;
}

二、PC端

1.tsx代码

import { Component, createRef } from 'react'
import './index.less'
interface Props {
 
 
}
interface State {
 
 
}
class TextDrag extends Component {
  disX: number = 0
  disY: number = 0
  x: number = 0
  y: number = 0
  dragElement = createRef()
  constructor(props: Props) {
    super(props)
    this.state = {
 
 
    }
  }
  FnDown(ev: React.MouseEvent) {
    if (this.dragElement.current) {
      this.disX = ev.clientX - this.dragElement.current?.getBoundingClientRect().left
      this.disX = ev.clientY - this.dragElement.current?.getBoundingClientRect().top
    }
    document.onmousemove = this.FnMove.bind(this)
    document.onmouseup = this.FnUp
  }
  FnMove(ev: MouseEvent) {
    this.x = ev.clientX - this.disX
    this.y = ev.clientY - this.disY
    if (this.dragElement.current) {
      this.dragElement.current.style.left = this.x + 'px'
      this.dragElement.current.style.top = this.y + 'px'
    }
  }
  FnUp() {
    document.onmousemove = null
    document.onmouseup = null
  }
  render() {
    return (
      
) } } export default TextDrag

2.css代码

.TextDrag{
    position: absolute;
    width: 100px;
    height: 100px;
    background-color: red;
}
