js移动端事件基础及常用事件库详解

function on(curEle,type,fn){
   curEle.addEventListener(type,fn,false);
  }
  var oBox = document.querySelector('.box');
  //移动端采用click存在300ms延迟
  // oBox.addEventListener('click',function(){
  //  this.style.webkitTransform = 'rotate(360deg)'
  // },false)
  //使用TOUCH事件模型实现点击操作(单击&&双击)
  on(oBox,'touchstart',function(ev){
   //ev:TouchEvent事件 属性 type、target、preventDefault（returnValue）、stopPropagation、changedTouches、touches
   //changedTouches和touches都是手指信息的集合（touchList）,touches获取到值的必要条件只有手指还在屏幕上才可以获取，所以在touchend事件中如果想获取手指离开的瞬间坐标只能使用changedTouches获取
   var point = ev.touches[0];
   this['strX'] = point.clientX;
   this['strY'] = point.clientY;
   this['isMove'] = false;
  })
  on(oBox,'touchmove',function(ev){
   var point = ev.touches[0];
   var newX = point.clientX,
    newY = point.clientY;
   //判断是否发生滑动，我们需要判断偏移的值是否在30PX以内
   if(Math.abs(newX-this['strX'])>30 || Math.abs(newY-this['strY'])>30){
    this['isMove'] = true;
   }
  })
  on(oBox,'touchend',function(ev){
   if(this['isMove'] === false){
    //没有发生移动 点击
    this.style.webkitTransitionDuration = '1s';
    this.style.webkitTransform = 'rotate(360deg)';
    var delayTimer = window.setTimeout(function(){
     this.style.webkitTransitionDuration = '0s';
     this.style.webkitTransform = 'rotate(0deg)';
    }.bind(this),1000);
   }else{
    //滑动
    this.style.background = 'red';

  })

var oBox = document.querySelector('.box');
  //单击
  touch.on(oBox,'tap',function(ev){
   this.style.webkitTransitionDuration = '1s';

    window.clearTimeout(delayTimer)
   }.bind(this),1000)
  })
  //长按
  touch.on(oBox,'hold',function(ev){
   this.style.backgroundColor = 'red';
