我的值是777。我需要上述数据，第一个元素有一个 custom_attributes>attribute_code === Brand 数组，它的值 === 777。我必须以这种方式进行过滤。同样在第二个数据中，我什至不存在 custom_attributes->attribute_code === Brand 。所以我应该删除这些数据，最后需要一个过滤后的数组。另外，在其他情况下，custom_attribute 中存在与数组 category_ids 匹配的数据，该数组是一个数组。因此，使用像 793 这样的特定值，我还需要进行过滤。
我尝试过的代码如下
let overAll = filt.items.filter(c => c.custom_attributes.map((i,j)=>{
if(i.attribute_code === "brand"){
return i.value === 777
}
}))
扩展输出:
{
"items": [
{
"id": 3844,
"sku": "aaa",
"name": "aaa",
"attribute_set_id": 4,
"price": 2222,
"status": 1,
"visibility": 4,
"type_id": "simple",
"custom_attributes": [
{
"attribute_code": "special_price",
"value": "2222.000000"
},
{
"attribute_code": "brand",
"value": "777"
},
{
"attribute_code": "category_ids",
"value": [
"75",
"791",
"793",
"799"
]
},
{
"attribute_code": "color",
"value": "5447"
},
{
"attribute_code": "size",
"value": "5432"
}
]
}
],
"search_criteria": {
"filter_groups": [
{
"filters": [
{
"field": "category_id",
"value": "75",
"condition_type": "eq"
}
]
}
],
"sort_orders": [
{

"direction": "DESC"
}
],
"page_size": 3,
"current_page": 1
},
"total_count": 3
}
最佳答案
你可以试试这个过滤器吗？
function filter(brand,no){
return el.items.filter(x=>x.custom_attributes.find(y=>y.attribute_code==brand && (y.value==no || y.value.includes(no)) ))
}
并调用它
filter("brand",777)
