javascript - How to run two cases with different functions at the same time? -

i know possible run multi cases if same action. considering example below, if true , b, something...

switch(true){  case a:  case b:   //do something;  break;  case c:   //do else;}  

however, not sure how make work following:

switch(true){  case a:   alert("a");  case b:   alert("b");  break;  case c:   //do else;}  

if true both , b, should alert "a" , "b". probably, switch statement not option example, not figure out. suggestion, recommendation?

i think you're trying use switch incorrectly, looks you're trying check if a, b , c true , if run matching alert(). purpose of switch check value being given (so 1 case can true) , run it, so:

function demofunction1(fruit){     var sentence = "";     switch (fruit) {         case "apple": sentence = "i love apples!"; break;         case "banana": sentence = "i hate bananas!"; break;         case "watermelon": sentence = "watermelon okay"; break;     }     alert(sentence); } 

so checking value of fruit is, if it's "apple", "banana" or "watermelon" run matching case's code.

it looks me wanna use if statements so:

function demofunction2(a, b, c){     if (a) {          alert("a");     }     if (b) {         alert("b");     }     if (c) {         alert("c");     } } 

this way you're checking if a, b , c true individually , if of them what's in {} of if statement run (such function calls or in case alerts). work combination of a, b , c being true/false.
