SPA项目开发--表单验证、增删改

1. 表单验证

Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
   并将Form-Item的prop属性设置为需校验的字段名即可
  
   <el-form-item label="活动名称" prop="name">
   <el-form :model="ruleForm" :rules="rules" ref="ruleForm"

1、

 <el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="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>

2、

 rules: {
           title: [{
               required: true,
               message: '请输入文章标题',
               trigger: 'blur'
             },
             {
               min: 3,
               max: 5,
               message: '标题长度在 3 到 5 个字符',
               trigger: 'blur'
             }
           ],
           body: [{
             required: true,
             message: '请输入文章内容',
             trigger: 'change'
           }]
         }

2、数据增删改

 <template>
   <div>
     <!-- 搜索筛选 -->
     <el-form :inline="true" :model="formInline" class="user-search">
       <el-form-item label="搜索：">
         <el-input size="small" v-model="formInline.title" placeholder="输入文章标题"></el-input>
       </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="handleAdd()">添加</el-button>
       </el-form-item>
     </el-form>
     <!--列表-->
     <el-table size="small" :data="listData" border element-loading-text="拼命加载中" style="min-width: 1;">
       <el-table-column align="center" type="selection" min-width="1">
       </el-table-column>
       <el-table-column sortable prop="id" label="文章的ID" min-width="1">
       </el-table-column>
       <el-table-column sortable prop="title" label="文章的标题" min-width="2">
       </el-table-column>
       <el-table-column sortable prop="body" label="文章的内容" min-width="4">
       </el-table-column>
       <el-table-column align="center" label="操作" min-width="2">
         <template slot-scope="scope">
           <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
           <el-button size="mini" type="danger" @click="deleteUser(scope.$index, scope.row)">删除</el-button>
         </template>
       </el-table-column>
     </el-table>
     <!-- 分页条 -->
             <el-pagination style="margin-top: 20px;" @size-change="handleSizeChange" @current-change="handleCurrentChange"
             :current-page="formInline.page" :page-sizes="[10, 20, 30, 50]" :page-size="100" layout="total, sizes, prev, pager, next, jumper"
             :total="total">
             </el-pagination>

     <!-- 编辑界面 -->
     <el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="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>
