elementUI表达自定义校验，校验在v-for中

<el-form :inline="true" :rules="rules" :model="formData" ref="formRef" class="mt-[20px]"><el-form-item label="选择区域" prop="area"><el-select v-model="formData.area" placeholder="请选择" @change="areaChange"><el-option v-for="item in areaList" :key="item.value" :label="item.name" :value="item.value"></el-option></el-select></el-form-item><el-row v-for="(item, index) in formData.content" :key="index" class="my-[20px]"><div><div class="mb-[10px]">{{ item.name }}：</div><divclass="border w-[400px] p-[10px] min-h-[45px]"style="border-radius: 5px; white-space: normal; word-break: break-all; border-color: #47536b"text="[14px]"@click="choiceSensor(item.name, item.ids)">{{ item.ids ? item.ids : "点击选择传感器" }}</div></div><div class="ml-[10px] flex items-center"><el-form-itemlabel="取值方式":prop="`content[${index}].valueWay`"style="margin-bottom: 0; margin-top: 20px":rules="[{ required: true, message: '请选择', trigger: 'blur' }]"><el-select v-model="item.valueWay" placeholder="请选择"><el-option v-for="item in valueWayList" :key="item.value" :label="item.name" :value="item.value"></el-option></el-select></el-form-item><el-form-itemlabel="环境阈值":prop="`content[${index}].threshold`"style="margin-bottom: 0; margin-top: 20px":rules="[{ required: true, message: '请输入环境阈值', trigger: 'blur' },{ pattern: rule0_1, message: '请输入大于等于1的1位小数', trigger: 'blur' },]"><el-input v-model="item.threshold" placeholder="环境阈值" /></el-form-item><el-form-itemlabel="浮动值":prop="`content[${index}].floating`"style="margin-bottom: 0; margin-top: 20px":rules="[{ required: true, message: '请输入环境阈值', trigger: 'blur' },{ pattern: rule0_1, message: '请输入大于等于1的1位小数', trigger: 'blur' },]"><el-input v-model="item.floating" placeholder="浮动值" /></el-form-item></div></el-row></el-form>

这里ts/js部分

const formRef = ref();
// 保留大于等于0的1位小数
export const rule0_1 = /^(0|[1-9]\d*)(\.\d)?$/
const formData = ref<any>({area: "",content: [{ name: "温度", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // 温度{ name: "湿度", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // 湿度{ name: "co", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // co{ name: "co2", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // co2{ name: "照度", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // 照度{ name: "PM2.5", ids: "", valueWay: "", threshold: "", floating: "", rule: rule0_1 }, // PM2.5],
});

其中取值方式，环境阈值，浮动值，均在循环中完成，自定义的的表单校验，同类型同一种校验
