                imgArr:[],
                }

imgArr：为图片地址

 getImgList(index) {
                let arr = []
                let i = 0;
                for(i;i < this.imgArr.length;i++){
                    arr.push(this.imgArr[i+index])
                    if(i+index >= this.imgArr.length-1){
                        index = 0-(i+1);
                    }
                }
                return arr;
            },
