• SPA项目开发之CRUD+表单验证


     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"  

    代码:

    <template>
      <div>
        <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="add()">添加</el-button>
          </el-form-item>
        </el-form>
        <!-- 列表-->
        <el-table :data="listData" stripe style=" 100%">
          <el-table-column prop="id" label="ID" width="390">
          </el-table-column>

            </template>
          </el-table-column>
        </el-table>
        <!-- 分页条 -->
