我以为是数组，但用下标无法获取内容

for(let i=0;i<src.length;i++)
        {
          wx.cloud.uploadFile({
            cloudPath:'annimages/'+time+i,
            filePath:src[i],
          })
          .then(res=>{
            p.push(res.fileID);
          })
        }
var pl = new Array();
pl = p;
console.log("pl",pl);
console.log("pl0",pl[0]);
