el-form中循环出来的el-form-item进行校验的设置

<template v-for="(e, index) in appAdnInfo.ext" :key="e.name">
            <el-form-item
              :label-width="labelWidth"
              :label="e.label"
              :prop="'ext.' + index + '.value'"
              :rules="[{ required: e.isChecked, message: e.name+'不能为空', trigger: 'blur' }]"
            >
              <el-input
                autocomplete="off"
                v-model="e.value"
                placeholder="请输入"
                :type="e.type"
                :disabled="e.disabled"
              />
            </el-form-item>
          </template>
