          <el-button
              size="small"
              type="danger"
              @click="handleDelete(scope.$index, scope.row)">Delete</el-button>
        </template>
      </el-table-column>
    </el-table>

    <el-dialog v-model="dialogFormVisible" title="Shipping address">
      <el-form :model="form">
        <el-form-item label="标题">
          <el-input v-model="form.title" autocomplete="off" />
        </el-form-item>
        <el-form-item label="Zones" >
          <el-radio-group v-model="form.completed">
            <el-radio :label="true">完成</el-radio>
            <el-radio :label="false">未完成</el-radio>
          </el-radio-group>
        </el-form-item>
      </el-form>
      <template #footer>
      <span class="dialog-footer">
        <el-button @click="dialogFormVisible = false">取消</el-button>
        <el-button type="primary" @click="saveOrUpdate">确定</el-button>
      </span>
      </template>
    </el-dialog>
  </el-container>

</template>

<script lang="ts" setup>
import {getScheduleList, saveSchedule, updateSchedule} from './api/schedule.js';
import {onMounted, reactive, ref} from 'vue';

let dialogFormVisible = ref(false);

let form=reactive({
  id: 0,
  title: '',
  completed: false
})
let form0=reactive({
  id: 0,
  title: '',
  completed:false
})
let resetFormData=()=>{
  Object.assign(form, form0);
}

let scheduleList=reactive([])

let loadData=()=>{
  getScheduleList().then(response=>{
    Object.assign(scheduleList,response.data.data)
  })
}

let saveOrUpdate=()=>{
  if (form.id === 0) {
    save();
  } else {
    update();
  }
}

let save=async()=>{
  await saveSchedule(form)
  dialogFormVisible.value=false
  resetFormData();
  loadData();
}

let toAdd=()=>{
  resetFormData();
  dialogFormVisible.value = true;
}

onMounted(()=>{
  loadData();
})

let update=async ()=>{
  await updateSchedule(form)
  dialogFormVisible.value = false
  loadData();
}

interface scheduleList {
  id: Number
  title: string
  completed: boolean
}

const handleEdit = row => {
  dialogFormVisible.value = true;
  Object.assign(form, row);
}
const handleDelete = (index: number, row: scheduleList) => {
  console.log(index, row)
}
</script>

 5、ScheduleController.java

package com.atguigu.schedule;
import com.atguigu.schedule.controller.Result;
import com.atguigu.schedule.pojo.Schedule;
import com.atguigu.schedule.service.ScheduleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@CrossOrigin
@RestController
@RequestMapping("/schedule")
public class ScheduleController {

    @Autowired
    private ScheduleService scheduleService;

    @GetMapping
    public Result list() {
        return Result.ok(scheduleService.getScheduleList());
    }

    @PostMapping
    public Result save(@RequestBody Schedule schedule) {
        scheduleService.add(schedule);
        return Result.ok();
    }

    @PutMapping
    public Result update(@RequestBody Schedule schedule) {
        scheduleService.update(schedule);
        return Result.ok();
    }

    @DeleteMapping("/{id}")
    public Result del(@PathVariable Integer id) {
        scheduleService.del(id);
        return Result.ok();
    }
}

6、async

     在Vue3中,async是一个关键字用于定义异步函数。异步函数可以用于处理需要花费一定时间的操作,如网络请求读取文件等。使用async关键字可以确保异步操作不会阻塞程序执行,使得程序可以继续执行其他任务,而不需要等待异步操作完成。

     在Vue3中,async函数通常用于处理异步请求,例如从后端API获取数据通过使用async函数,可以在不阻塞整个程序的情况下等待异步操作完成,并返回结果。这使得Vue3可以更高效地处理异步操作,并提高程序响应速度和性能

下面是一个使用async函数的示例

async function fetchData() {  
  try {  
    const response = await axios.get('https://api.example.com/data');  
    const data = response.data;  
    // 处理数据  
    return data;  
  } catch (error) {  
    // 处理错误  
  }  
}

在这个示例中,使用async关键字定义了一个异步函数fetchData(),它使用axios发送一个GET请求指定的URL,并等待响应完成。在等待的过程中,程序不会阻塞,可以继续执行其他任务。当响应完成时,程序返回响应数据,并可以在需要时使用这些数据进行渲染。如果请求失败,程序会捕获错误处理
