数组对象和一般数组之间的转换

将一般数组转为对象数组

    // imgList = this.masterImgList    arr = this.srcList
let imgList= [
            "../../beehive-scenes.jpg_180x180xzq90.jpg_.webp",
            "../../beehive-scenes.jpg_180x180xzq90.jpg_.webp",
             "../../pXa_!!693063332.jpg_180x180xzq90.jpg_.webp",
             "../../180x180xzq90.jpg_.webp",
             "../../dgshop.jpg_180x180xzq90.jpg_.webp"
   ]
      let arrList = [];
      for (let i in imgList) {
        arrList.push(imgList[i]);
      }
      for (var i = 0; i < arrList.length; i++) {

        arr.push(j);

    }
  console.log(imgList);
