vue element实现增删

Vue + Element UI 实现增删功能

依赖安装 确保项目已安装 Vue 和 Element UI：

npm install vue element-ui

基础表格结构 在 Vue 组件中引入 Element UI 表格组件，并定义数据与操作按钮：

<template>
  <div>
    <el-button type="primary" @click="handleAdd">新增</el-button>
    <el-table :data="tableData" style="width: 100%">
      <el-table-column prop="name" label="姓名"></el-table-column>
      <el-table-column prop="age" label="年龄"></el-table-column>
      <el-table-column label="操作">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
          <el-button size="mini" type="danger" @click="handleDelete(scope.$index)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>

    <!-- 新增/编辑对话框 -->
    <el-dialog :title="dialogTitle" :visible.sync="dialogVisible">
      <el-form :model="formData">
        <el-form-item label="姓名">
          <el-input v-model="formData.name"></el-input>
        </el-form-item>
        <el-form-item label="年龄">
          <el-input v-model.number="formData.age"></el-input>
        </el-form-item>
      </el-form>
      <div slot="footer">
        <el-button @click="dialogVisible = false">取消</el-button>
        <el-button type="primary" @click="submitForm">确认</el-button>
      </div>
    </el-dialog>
  </div>
</template>

数据与逻辑实现

<script>
export default {
  data() {
    return {
      tableData: [
        { name: '张三', age: 20 },
        { name: '李四', age: 25 }
      ],
      dialogVisible: false,
      dialogTitle: '新增',
      formData: {
        name: '',
        age: null
      },
      editIndex: -1
    }
  },
  methods: {
    handleAdd() {
      this.dialogTitle = '新增';
      this.formData = { name: '', age: null };
      this.editIndex = -1;
      this.dialogVisible = true;
    },
    handleEdit(index, row) {
      this.dialogTitle = '编辑';
      this.formData = { ...row };
      this.editIndex = index;
      this.dialogVisible = true;
    },
    handleDelete(index) {
      this.$confirm('确认删除?', '提示', {
        type: 'warning'
      }).then(() => {
        this.tableData.splice(index, 1);
        this.$message.success('删除成功');
      });
    },
    submitForm() {
      if (this.editIndex === -1) {
        this.tableData.push({ ...this.formData });
      } else {
        this.tableData.splice(this.editIndex, 1, { ...this.formData });
      }
      this.dialogVisible = false;
      this.$message.success('操作成功');
    }
  }
}
</script>

关键点说明

• 通过 splice 方法实现删除和更新操作
• 使用 { ...object } 进行对象浅拷贝避免数据绑定问题
• 对话框复用处理新增和编辑两种状态
• 通过 editIndex 标记当前操作的行索引

样式补充 可添加 CSS 调整间距：

<style scoped>
.el-button {
  margin-bottom: 15px;
}
</style>

扩展功能建议

1. 添加表单验证规则
2. 集成后端 API 调用
3. 增加分页控件
4. 实现批量删除功能
