touchend中处理最终效果，如果滑动距离不大于某一值则恢复原位，否则切换。
touchEnd() {
console.log("end");
console.log(this.percent);
let offsetWidth
let percent
//当前为红色，滑动占比大于0.1则切换，否则回到原位置
if(this.currentPlay === 'red'){
if(this.percent > 0.1) {
this.currentPlay = 'yellow'
offsetWidth = -window.innerWidth
} else {
offsetWidth = 0
}
} else {
//当前为黄色，滑动占比大于0.9则切换，否则回到原位置
if(this.percent < 0.9) {
this.currentPlay = 'red'
offsetWidth = 0
} else {
offsetWidth = -window.innerWidth
}
}
//这里的transform是针对最开始的位置而言，而不是移动过程中的位置
this.$refs.back.style["transform"] = `translate3d(${offsetWidth}px,0,0)`
this.$refs.back.style["transitionDuration"] = 10
