如何使用具有多个值集的值编写 if else 语句？

Question

So for my 'f' value, it has from 1-15. How do I write my if-else statement if I want if f value == 1,6,7,8,9,10,12 it does something if-else f value == 2,3,4,5,13,14,15 do something else?

 if(a == "BLK A ", d == "BLK D ", e == "5", f == "1 "){
        // do something
    } 
    else if (f =="6"){
        // do something
    }

Answer 1

You could take Array#includes with the wanted values.

It is necessary to take the same type of the value, like string or numbers. If different types, you need to normalize the value to all numbers or strings.

 if (['1', '6', '7', '8', '9', '10', '12'].includes(f)) { }

Answer 2

you can use the parseInt() function:

var valueOfF = parseInt(f)

if(valueOfF >=1 && valueOfF <=10){

    //doSomething
}
else if(valueOfF >=11 && valueOfF <= 15){

    //doSomething
}
