web front end using a mobile event react, the study notes

Use a mobile-side event:
          onTouchStartCapture        onTouchStart
          onTouchMoveCapture       onTouchMove
          onTouchEndCapture          onTouchEnd
There are events that capture Capture event (an event is triggered from outside to inside), there is a bubbling event (an event is triggered from the inside out).
 
  Event binding: binding events to list in this way, the mobile end user can determine the trigger is to click on the screen or swipe event:
 <div className="footer-nav"
                    onTouchStartCapture={(e)=>{this.start(e)}}
                    onTouchMoveCapture={(e)=>{this.move(e)}}
                    onTouchEndCapture={(e)=>this.end(e)}
                >
                    <div className="nav" onTouchEndCapture={()=>this.toRouter("/index")}>
                        <img src={img1} alt="" />
                        <P> ha </ p>
                    </div>
                    <div className="nav" onTouchEndCapture={()=>this.toRouter("/index")}>
                        <img src={img2} alt="" />
                        <P> Goo </ p>
                    </div>
      </div>
Click to distinguish between mobile terminal or slip event methods:
toRouter(url){
        this.props.history.push(url)
    }
 
    old = 0;
    endY=0;
    start (e) {
        // this.startY=e.touches[0].clientY;
        this.endY=0;
    }
    move(e){
        this.endY=e.touches[0].clientY;
    }
    end(e){
        // console.log(this.startY,this.endY)
        // if(this.endY>this.startY){  
        // console.log ( "stated that this is the decline events")
        // }
        // if(this.startY>this.endY){
        // console.log ( "Description This is a slip event")
        // }
        if (this.endY! = 0) {// event description is slidably
            e.stopPropagation (); // stop event propagation,
        }
    }
