我有以下使用

我想对其进行重构，如果行请参阅代码，请删除所有这些else

，

useEffect(() => {
    if(country === "WW") {
        setIsDisable(true);
    } else if (country === "GB") {
        setIsDisable(false);
    } else if (country === "DE") {
        setIsDisable(false);
    } else if (country === "FR") {
        setIsDisable(false);
    } else if (country === "BR") {
        setIsDisable(false);
    } else if (country === "US") {
        setIsDisable(false);
    } else if (country === "IT") {
        setIsDisable(false);
    } else if (country === "US") {
        setIsDisable(false);
    } else if (country === "ES") {
        setIsDisable(false);
    } else if (country === "MX") {
        setIsDisable(false);
    }
  }, [country]);

请参阅国家：gb， de，fr，br，us，it，us /code>，es和mx共享相同的setIsdisable（false）

如何在1行代码中写入相同的代码whitout重复相同否则，如果？

I have the following useEffect

I want to refactor it, removing all these else if lines

See the code

useEffect(() => {
    if(country === "WW") {
        setIsDisable(true);
    } else if (country === "GB") {
        setIsDisable(false);
    } else if (country === "DE") {
        setIsDisable(false);
    } else if (country === "FR") {
        setIsDisable(false);
    } else if (country === "BR") {
        setIsDisable(false);
    } else if (country === "US") {
        setIsDisable(false);
    } else if (country === "IT") {
        setIsDisable(false);
    } else if (country === "US") {
        setIsDisable(false);
    } else if (country === "ES") {
        setIsDisable(false);
    } else if (country === "MX") {
        setIsDisable(false);
    }
  }, [country]);

As you can see the country: GB, DE, FR, BR, US, IT, US, ES and MX sharing the same setIsDisable(false)

How would you write in 1 line of code whitout repeating the same else if ?

useEffect(() => {
   setIsDisable(country === "WW");
}, [country]);

如果您想验证

useEffect(() => {
   if (country === "WW")
      setIsDisable(true);
   else if (["GB", "DE", "FR", "BR", "US", "IT", "ES", "MX"].includes(country))
      setIsDisable(false);
}, [country]);

useEffect(() => {
   setIsDisable(country === "WW");
}, [country]);

if you want to validate

useEffect(() => {
   if (country === "WW")
      setIsDisable(true);
   else if (["GB", "DE", "FR", "BR", "US", "IT", "ES", "MX"].includes(country))
      setIsDisable(false);
}, [country]);
