获取到一个数据中，嵌套着二级数据，此时，比如获取到分类(商品)，此时仅需要渲染商品，而不需要分类，且他俩有部分共同的属性，没学多少，不知道有什么更高效的方法，所以我遍历了。
接口数据
代码语言：javascript复制{
"code": 200,
"data": [{
"id": 1,
"sortname": "数码电器",
"sortimg": "2",
"sortdes": "The digital electrical appliances",
"addtime": "2022-10-30",
},
{
"id": 2,
"sortname": "家居家具",
"sortimg": "2",
"sortdes": "Household furniture",
"addtime": "2022-10-30",
"children": [{
"id": 21,
"fruit": "小米12",
"pic": "/src/assets/images/1.jpg",
"price": 2999,
"adddate": "2022-10-30",
"state": false
},
{
"id": 22,
"fruit": "苹果15",
"pic": "/src/assets/images/1.jpg",
"price": 5999,
"adddate": "2022-10-30",
"state": true
}
]
},
{
"id": 3,
"sortname": "水果生鲜",
"sortimg": "7",
"sortdes": "Fresh fruit",
"addtime": "2022-10-30",
"children": [{
"id": 31,
"fruit": "青柠",
"pic": "/src/assets/images/1.jpg",
"price": 5,
"adddate": "2022-10-30",
"state": true
},
{
"id": 32,
"fruit": "柚子",
"pic": "/src/assets/images/2.jpg",
"price": 4.5,
"adddate": "2022-10-30",
"state": false
},
{
"id": 33,
"fruit": "橘子",
"pic": "/src/assets/images/3.jpg",
"price": 3,
"adddate": "2022-10-30",
"state": false
},
{
"id": 36,
"fruit": "柠檬",
"pic": "/src/assets/images/6.jpg",
"price": 4,
"adddate": "2022-10-30",
"state": false
},
]
},
{
"id": 4,
"sortname": "美妆清洁",
"sortimg": "12",
"sortdes": "Beauty makeup clean",
"addtime": "2022-10-30",
"children": [{
"id": 41,
"fruit": "洗面奶",
"pic": "/src/assets/images/1.jpg",
"price": 9.9,
"adddate": "2022-10-30",
"state": true
},
{
"id": 42,
"fruit": "神仙水",
"pic": "/src/assets/images/1.jpg",
"price": 999,
"adddate": "2022-10-30",
"state": true
}
]
},
]
}forEach遍历
代码语言：javascript复制 res.forEach((item, index) => {
if (item.chilren !== null) {
if (item.children === undefined) {
return null;
}
let newarr = item.children;
// console.log(newarr);
arr.push(...newarr);
} else {
return false;
}
// console.log(arr);
tableData.value = arr;首先获取到包含二层数据的数组，并获取到二层数组，然后进行数组拼接，最后拿到一个新的仅包含所有二层数组值的新数组。
渲染表格
代码语言：javascript复制 <el-table :data="tableData">
<el-table-column type="selection" />
<el-table-column prop="id" label="id" />
<el-table-column prop="fruit" label="商品名称" show-overflow-tooltip />
<el-table-column prop="pic" label="缩略图">
<template #default="scope"> <img :src="scope.row.pic" alt="" class="goodsimg" /> </template>
</el-table-column>
<el-table-column prop="price" label="商品价格">
<template #default="scope"> {{ scope.row.price }} 元</template>
</el-table-column>
<el-table-column prop="adddate" label="添加时间"> </el-table-column>
<el-table-column label="上架" prop="state">
<template #default="scope"> <el-switch v-model="scope.row.state" /></template>
</el-table-column>
<el-table-column fixed="right" label="操作">
<template #default="scope">
<el-button type="primary" size="small" @click="handleEdit(scope.row)">编辑</el-button>
<el-button type="danger" size="small" @click="handleDelete(scope.row)">删除</el-button>
</template>
</el-table-column>
</el-table>Element-Plus有一个树形数据来渲染嵌套数据，但是不是我想要的。
正在自学，如果路过的大佬有更好的方法请告知一下！
