如何从 onChange 事件中过滤 json 数组中的多个 json 项

Question

我有一个 react-select 组件，我正在从中获取多个值。然后我试图在 JSON 数组中找到所有匹配项。我一直在尝试一段时间无法找出最好的方法。我想过滤并打印匹配项。下面是数据。我想获取与所选症状匹配的所有条件。

export const symptomsCondition = [
  {
    condition: "Acetaminophen And Nsaid Toxicity",
    symptions: ["Disorganized Speech", "Insomnia"],
  },
  {
    condition: "Acne",
    symptions: ["Swelling (Axilla)", "Bleeding Easily", "Difficult To Wake Up", "Increased Thirst"],
  },
  {
    condition: "Adrenal Disorders (Addison’S Disease And Cushing’S Syndrome",
    symptions: ["Weakness (Leg)", "Tremor", "Premature Ejaculation"],
  },
  {
    condition: "Age Related Cognitive Decline",
    symptions: ["Swelling (Jaw)", "Furry Tongue", "Headache (Worst Ever)", "Mucus In Eyes"],
  },
  {
    condition: "Alcohol: Reducing The Risks",
    symptions: [
      "Pulling Out Eyebrows",
      "Bleeding (Toes)",
      "Craving To Eat Ice",
      "Weakness (Shoulder)",
      "Pounding Heart",
    ],
  },
  {
    condition: "Allergies",
    symptions: ["Thick Saliva", "Unable To Grip (Hands)", "Irregular Heartbeat"],
  },

 const [yoursymptoms, setYourSymptoms] = useState(null);

  useEffect(() => {
    symptomsCondition.symptoms.find((yoursymptoms) => 
    console.log(yoursymptoms);
    )
  }, [yoursymptoms]);

onChange={setYourSymptoms}

Answer 1

您必须根据要求的条件在阵列上使用 filter。类似于：

const allConditions = symptomsConditions.filter(c => c.symptions.includes(yoursymptoms))

如果你只需要条件，你可以用

链接它

.map(c => c.conditon)
