使用react-draggable实现拖拽

1.先安装react-draggable

npm i react-draggable

2.利用Draggable包裹要拖拽内容

 <div className='box'>
          {this.state.list.map((item, index) => (
            <Draggable bounds={{ left: 0,top:0 }}>
              <div className='box1' key={index}>
                <img src={item.pic} className='boximg'></img>
                <p>{item.txt}</p>
                <div className='shan'>X</div>
              </div>
            </Draggable>
 
          ))}
        </div>

3.设置拖拽的区域 利用bounds属性，如上面代码
