javascript - Switch case not working for Images stored in array -


relating previous question , had images which(if 3 of specific image) same, wanted message appear, followed several guidelines previous question still cant work.

previous question: how make if statement specific image source?

it prints else statement, if 3 images of x appear, prints nothing main message, same problem occurs when 3 images of y appear(at once) or z. appreciated.

new code (tad bit) :

function xyz()  {       if((document.test.test1.src == document.test.test2.src && document.test.test2.src == document.test.test3.src ))         switch (document.test.test1.src == document.test.test2.src == document.test.test3.src) {             case "x":                 document.test.banner.value =("3 x")// stuff                 break;             case "y":                 document.test.banner.value =("5 y")                 break;             case "z":             document.test.banner.value =("8 z")             break;         }      else      {         document.test.usertokens.value=document.test.usertokens.value-document.test.bet.value;          document.test.banner.value="no match - lost ";     } }

here problem:

switch (document.test.test1.src == document.test.test2.src == document.test.test3.src)

the switch statement evaluates value put parenthesis. comparing .srcs, return boolean switch evaluate instead of strings hoping for. no need compare them in switch, seeing know same. need know 1 of them.

secondly, found interesting used syntax (a == b == c. did testing , does. equivalent ((a==b)==c). evaluates left right. first, (a==b) return boolean. compares boolean c, , i'm guessing "c" isn't boolean, return false.

looking @ previous question

switch (document.test.test1.src) {       case 'y':         ........         break;       case 'x'         ........         break; }

,as suggested dewd, seems appropriate choice if decide stick switch.

hope helped.
