Antd 的嵌套表格组件的数据源有要求:
数据结构修改前后示例
// 处理之前
const categoryList = [
{
categoryId: 1,
name: '1级',
children: [
{
categoryId: 11,
name: '11级',
children: [],
},
],
},
{
categoryId: 2,
name: '2级',
children: []
}
]
// 处理之后
const categoryList = [
{
value: 1,
label: '1级',
children: [
{
value: 11,
label: '11级',
},
],
},
{
value: 2,
label: '2级',
}
]
// 数据源
const categoryList = [
{
categoryId: 1,
name: '1级',
children: [
{
categoryId: 11,
name: '11级',
children: [],
},
],
},
{
categoryId: 2,
name: '2级',
children: []
}
]
// 迭代器
const iterator = function (arr, cb) {
for (let i = 0; i < arr.length; i++) {
cb.call(arr[i], arr[i])
}
}
// 处理每一项
const changeItem = function (item) {
item.value = item.categoryId
item.label = item.name
delete item.categoryId
delete item.name
if (item.children == false) {
delete item.children
} else {
iterator(item.children, changeItem)
}
}
// 调用迭代器
iterator(categoryList, changeItem)
console.log(JSON.stringify(categoryList, null, 4))
/*
