3.发生的问题:

TypeError: Cannot read property 'includes' of undefined
(anonymous function)
src/containers/Home.js:77
  74 |    item.category = categories[item.cid]
  75 |    return item
  76 |  }).filter(item=>{
> 77 |    return  item.data.includes(`${currentDate.year}-${padLeft(currentDate.month)}`)
     | ^  78 |  })
  79 | 
  80 | itemsWithCatory.forEach(item=>{

这个问题怎么解决,后面我把这行代码改成了

.filter(item=>{
     return item.data && item.data.includes(`${currentDate.year}-${padLeft(currentDate.month)}`)
   })
   或者:
   if(item.data ){
       return  item.data.includes(`${currentDate.year}-${padLeft(currentDate.month)}`)
     }

结果数据全部不显示了
