{ "value" : [ { "name": "a", "number": 11, }, { "name": "b", "number": 11, }, ] }使用ts将这个json串的name属性变为label属性

可以使用以下 TypeScript 代码将这个 JSON 串的 `name` 属性变为 `label` 属性：

const jsonString = '{ "value": [ { "name": "a", "number": 11 }, { "name": "b", "number": 11 } ] }';
const jsonObject = JSON.parse(jsonString);

// 遍历数组中的每个对象，将 name 属性改为 label 属性
jsonObject.value.forEach((obj: any) => {
  obj.label = obj.name;
  delete obj.name;
});

// 将修改后的对象转换为 JSON 字符串
const modifiedJsonString = JSON.stringify(jsonObject);
console.log(modifiedJsonString);

输出结果为：

{"value":[{"number":11,"label":"a"},{"number":11,"label":"b"}]}

需要注意的是，由于 TypeScript 是一种类型安全的语言，因此在遍历 JSON 数组中的每个对象时，需要将对象的类型声明为 `any` 或其他具体的类型。

<script lang="ts" setup> import { computed, ref } from "vue"; interface User { date: string; name: string; address: string; } const search = ref(""); const filterTableData = computed(() => tableData.filter( (data) => !search.value || data.name.toLowerCase().includes(search.value.toLowerCase()) ) ); const handleEdit = (index: number, row: User) => { console.log(index, row); }; const handleDelete = (index: number, row: User) => { console.log(index, row); }; const tableData: User[] = [ { date: "2016-05-03", name: "Tom", address: "No. 189, Grove St, Los Angeles", }, { date: "2016-05-02", name: "John", address: "No. 189, Grove St, Los Angeles", }, { date: "2016-05-04", name: "Morgan", address: "No. 189, Grove St, Los Angeles", }, { date: "2016-05-01", name: "Jessy", address: "No. 189, Grove St, Los Angeles", }, ]; </script>怎么改成JS格式

你可以将 `<script lang="ts" setup>` 修改为 `<script>`，表示使用普通的 JavaScript 语法。同时，你需要添加类型声明，例如：

import { computed, ref } from "vue";

const search = ref("");
const tableData = [
  {
    date: "2016-05-03",
    name: "Tom",
    address: "No. 189, Grove St, Los Angeles"
  },
  {
    date: "2016-05-02",
    name: "John",
    address: "No. 189, Grove St, Los Angeles"
  },
  {
    date: "2016-05-04",
    name: "Morgan",
    address: "No. 189, Grove St, Los Angeles"
  },
  {
    date: "2016-05-01",
    name: "Jessy",
    address: "No. 189, Grove St, Los Angeles"
  }
];

/**
 * @type {import("vue").ComputedRef<User[]>}
 */
const filterTableData = computed(() =>
  tableData.filter(
    (data) =>
      !search.value || data.name.toLowerCase().includes(search.value.toLowerCase())
  )
);

/**
 * @param {number} index
 * @param {User} row
 */
const handleEdit = (index, row) => {
  console.log(index, row);
};

/**
 * @param {number} index
 * @param {User} row
 */
const handleDelete = (index, row) => {
  console.log(index, row);
};

需要注意的是，你需要自己添加类型声明，这里的 `User` 类型可以根据你的实际需求进行修改。

这个用vue2怎么写:<template> <a-table :row-selection="rowSelection" :columns="columns" :data-source="data" /> </template> <script lang="ts"> import { defineComponent, computed, ref, unref } from 'vue'; import { ColumnProps } from 'ant-design-vue/es/table/interface'; type Key = ColumnProps['key']; interface DataType { key: Key; name: string; age: number; address: string; } const columns = [ { title: 'Name', dataIndex: 'name', }, { title: 'Age', dataIndex: 'age', }, { title: 'Address', dataIndex: 'address', }, ]; const data: DataType[] = []; for (let i = 0; i < 46; i++) { data.push({ key: i, name: `Edward King ${i}`, age: 32, address: `London, Park Lane no. ${i}`, }); } export default defineComponent({ setup() { const selectedRowKeys = ref<Key[]>([]); // Check here to configure the default column const onSelectChange = (changableRowKeys: Key[]) => { console.log('selectedRowKeys changed: ', changableRowKeys); selectedRowKeys.value = changableRowKeys; }; const rowSelection = computed(() => { return { selectedRowKeys: unref(selectedRowKeys), onChange: onSelectChange, hideDefaultSelections: true, selections: [ { key: 'all-data', text: 'Select All Data', onSelect: () => { selectedRowKeys.value = [...Array(46).keys()]; // 0...45 }, }, { key: 'odd', text: 'Select Odd Row', onSelect: (changableRowKeys: Key[]) => { let newSelectedRowKeys = []; newSelectedRowKeys = changableRowKeys.filter((key, index) => { if (index % 2 !== 0) { return false; } return true; }); selectedRowKeys.value = newSelectedRowKeys; }, }, { key: 'even', text: 'Select Even Row', onSelect: (changableRowKeys: Key[]) => { let newSelectedRowKeys = []; newSelectedRowKeys = changableRowKeys.filter((key, index) => { if (index % 2 !== 0) { return true; } return false; }); selectedRowKeys.value = newSelectedRowKeys; }, }, ], }; }); return { data, columns, selectedRowKeys, rowSelection, }; }, }); </script>

以下是Vue2版本的代码，对应你提供的模板：

<template>
  <a-table :row-selection="rowSelection" :columns="columns" :data-source="data" />
</template>

<script>
export default {
  data() {
    return {
      columns: [
        {
          title: 'Name',
          dataIndex: 'name',
        },
        {
          title: 'Age',
          dataIndex: 'age',
        },
        {
          title: 'Address',
          dataIndex: 'address',
        },
      ],
      data: [],
      selectedRowKeys: [],
    };
  },
  created() {
    for (let i = 0; i < 46; i++) {
      this.data.push({
        key: i,
        name: `Edward King ${i}`,
        age: 32,
        address: `London, Park Lane no. ${i}`,
      });
    }
  },
  computed: {
    rowSelection() {
      return {
        selectedRowKeys: this.selectedRowKeys,
        onChange: this.onSelectChange,
        hideDefaultSelections: true,
        selections: [
          {
            key: 'all-data',
            text: 'Select All Data',
            onSelect: () => {
              this.selectedRowKeys = Array.from({ length: 46 }, (_, i) => i);
            },
          },
          {
            key: 'odd',
            text: 'Select Odd Row',
            onSelect: () => {
              this.selectedRowKeys = this.selectedRowKeys.filter((key, index) => index % 2 !== 0);
            },
          },
          {
            key: 'even',
            text: 'Select Even Row',
            onSelect: () => {
              this.selectedRowKeys = this.selectedRowKeys.filter((key, index) => index % 2 === 0);
            },
          },
        ],
      };
    },
  },
  methods: {
    onSelectChange(changableRowKeys) {
      console.log('selectedRowKeys changed: ', changableRowKeys);
      this.selectedRowKeys = changableRowKeys;
    },
  },
};
</script>
