代码是用react写的，问题是这样的
1、chrome下，鼠标按下->移动。会触发ontouchstart，不触发ontouchmove
部分代码如下：请问一下谁知道问题可能出在哪啊？

handleDownTest(){
    console.log('handleDownTest')
    let target = document.querySelector(`#test1`)
    target.ontouchmove = this.handlemovetest.bind(this,target )
    target.ontouchup = this.handleuptest.bind(this)
  }

  handlemovetest(target ){
    console.log('handlemovetest')
    target.style.color = 'red';
  }

  handleuptest(target ){
    console.log('handleuptest')
    target.onmousemove = null
    target.onmouseup = null
  }
render() {
    const { value } = this.props

    return (
      <div id='test1' onTouchStart={this.handleDownTest.bind(this)}>
        qwqwqwqwqw
      </div>
    )
  }
}
