仿探探滑动如何设置点击效果

**如何点击左右切换呢请指教

touchEndNext(index) {
                console.log(index)
                this.slideing = true;
                this.listArr[index].x = this.listArr[index].x * 3;
                this.listArr[index].y = this.listArr[index].y * 3;
                var a = setTimeout(() => {
                    this.$set(this.listArr[index], "show", false);
                    this.$nextTick(() => {
                        this.currentIndex++;
                        if (index + 3 < this.listArr.length) {
                            this.$set(this.listArr[index + 3], "opacity", 1);
                        }
                        this.slideing = false
                        a;
                    });

```    **

把滑动事件改点击里不就行了

点击没反应，然后没有x,y值尴尬
