一、表单验证

1、出现表单组件 el-form

2、通过点击新增/编辑将表单对应窗口弹出

3、给表单设置规则 rules

4、当表单提交时要校验规则

<!-- 编辑界面 -->
    <el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
      <el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
        <el-form-item label="文章标题" prop="title">
          <el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
        </el-form-item>
        <el-form-item label="文章内容" prop="body">
          <el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button size="small" @click="closeDialog">取消</el-button>
        <el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
      </div>
    </el-dialog>

<script>
export default {
  name: 'Articles',
  data() {
    return {
      title: '',
      editFormVisible: false,
      editForm: {
        title: '',
        body: '',
        id:0
      },
      rules: {
        title: [
          {required: true, message: '请输入文章标题', trigger: 'blur'},
          {min: 5, max: 10, message: '长度须在 5 到 10 个字符之间', trigger: 'blur'}
        ],
        body: [
          {required: true, message: '请输入文章内容', trigger: 'blur'}
        ],

      },

      listData: [],
      formInline: {
        page: 1,
        total: 10,
        title: ''
      }
    }
  },
  methods: {
    handleSizeChange(rows) {
      this.formInline.page = 1;
      this.formInline.rows = rows;
      this.search();
    },
    handleCurrentChange(page) {
      this.formInline.page = page;
      this.search();
    },

    doSearch(param) {
      // 获取树形节点的数据
      let url = this.axios.urls.SYSTEM_ARTICLE_LIST;

      //this指的是vue实例
      this.axios.post(url, param)
        .then(resp => {//代表成功 箭头函数 jdk8的语法
          console.log(resp);
          this.listData = resp.data.result;
          this.formInline.total = resp.data.pageBean.total;
        }).catch(function () {//代表失败

      });
    },
    search() {
      //  按照条件进行查询
      this.doSearch(this.formInline);
    },
    closeDialog() {
      //  关闭窗体
      this.clearData();
    },
    clearData(){
    //  清楚编辑窗体的缓存数据
      this.editForm.title='';
      this.editForm.id=0;
      this.editForm.body='';
      this.title='';
      this.editFormVisible=false;
    },
    handleEdit(index,row) {
      this.clearData();
      // 展示新增文章的表单
      this.editFormVisible = true;
      if(row){
        //  编辑
        this.title='编辑窗体';
        this.editForm.id = row.id;
        this.editForm.title = row.title;
        this.editForm.body=row.body
      }else{
        //新增
        this.title='新增窗体';
      }

    },
  created() {
    this.doSearch({});
  }
}
</script>

 

 

二、增删改查 

1、保障编辑窗体能够正常弹出

2、表单校验通过后，调用后台数据接口完成新增功能

<template>
  <div>
    <!--  搜索筛选-->
    <el-form :inline="true" :model="formInline" class="user-search">
      <el-form-item label="搜索：">

      </el-form-item>
      <el-form-item>
        <el-button size="small" type="primary" icon="el-icon-search" @click="search">搜索</el-button>
        <el-button size="small" type="primary" icon="el-icon-plus" @click="handleEdit()">添加</el-button>
      </el-form-item>
    </el-form>

    <!--列表-->
