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
