form 表单添加校验规则

form 表单添加校验规则

1、在表单的每一项上单独加

  <el-form-item
    label="配置属性: "
    :prop="'paramPairs.' + index + '.name'"
    :rules="[{required: true, message: '属性名不能为空', trigger: 'blur'}, {max: 100, message: '不能超过 100 个字符', trigger: 'blur' }]"
 >
   <el-input v-model="param.name" placeholder="属性名" />
 </el-form-item>

2、在表单头上总体加校验

	<el-form ref="serviceTemplate" :rules="formRules" :model="serviceTemplate" :disabled="operationType === 'view'"
               label-width="80px">
        <el-form-item prop="id" />
        <el-form-item label="名称: " prop="name">
          <el-input v-model="serviceTemplate.name" placeholder="模版名称" :disabled="operationType !== 'add'" style=" 25%" />
        </el-form-item>

        <el-form-item label="探测: " prop="indicatorType">
          <el-select v-model="serviceTemplate.indicatorType" placeholder="请选择" style=" 25%">
            <el-option
              v-for="item in indicatorTypes"
              :key="item.value"
              :label="item.name"
              :value="item.value" />
          </el-select>
        </el-form-item>

        <el-form-item label="类型: " prop="type">
          <el-select v-model="serviceTemplate.type" placeholder="请选择" style=" 25%">
            <el-option
              v-for="item in serviceTemplateTypes"
              :key="item.name"
              :label="item.name"
              :value="item.name" />
          </el-select>
        </el-form-item>

        <el-form-item>
          <el-row gutter="20">
            <el-col span="6" style="margin-left: 15px">
              属性名
            </el-col>
            <el-col span="4">

          </el-row>
        </el-form-item>
        <el-form-item prop="paramPairs" style="margin-bottom: 0" />

        <el-row
          gutter="24"
          v-for="(param,index) in serviceTemplate.paramPairs"
          :key="index"
        >
          <el-col span="6">
            <el-form-item
              label="配置属性: "

              <el-input v-model="param.name" placeholder="属性名" />
