code is written in react. The problem is this: 
 1, chrome, mouse down-> move. The code that triggers ontouchstart, but does not trigger ontouchmove 
 is as follows: who knows what the problem may be? 
handleDownTest(){
    console.log("handleDownTest")
    let target = document.querySelector(`-sharptest1`)
    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>
    )
  }
}
