遍历el-form-item表单项，并绑定rules

<el-form ref="bannerImgSettingForm" label-width="80px" :model="bannerImgSettingForm" :rules="rules" >
   <div v-for="(item, index) in bannerImgSettingForm.bannerImgSettingList" :key="index">
     <el-form-item
     :label="item.urlLabel" 
     :prop="`bannerImgSettingList[${index}].link`"
     :rules="rules.link"
     >
       <el-input v-model="item.link" clearable ></el-input>
     </el-form-item>
   </div>
   <el-form-item>
     <el-button @click="handleCancel">取消</el-button>
     <el-buttontype="primary" @click="onSubmit2('bannerImgSettingForm')">确认</el-button>
   </el-form-item>
 </el-form>
           

rules: {
  link: [
    { validator: validatePass, trigger: 'blur' }
  ],
},

bannerImgSettingForm: {
  bannerImgSettingList: [
    {
      urlLabel: '链接1：',
      link: ''
    },
    {
      urlLabel: '链接2：',
      link: ''
    },
    {
      urlLabel: '链接3：',
      link: ''
    },
    {
      urlLabel: '链接4：',
      link: ''
    },
    {
      urlLabel: '链接5：',
      link: ''
    }
  ],
},
           

onSubmit2(formName) {
 this.$refs[formName].validate((valid) => {
   if (valid) {
     console.log(this.bannerImgSettingForm.bannerImgSettingList,'校验通过');
   } else {
     console.log('error submit!!');
     return false;
   }
 });
},
