我如何在不离开循环的情况下停止循环（无“中断”）

Question

For example I have this:

for (i = 0; i < wLength; i++) {
   if(dummy === word.charAt(i)) {
        letters[i] = dummy;
        //cs == 0 ? score1++ : score2++
   } else {
      fail++
      break;
   }
}

It will increment 'fail' as many times as the 'wLength' , but I just want it to increment once each iteration (if 'dummy' is false) and without using break (because it will leave the entire loop).

Answer 1

You can try with "continue". It will go to next round of loop without leaving it.

 for(i = 0; i < wLength; i++){
    if(dummy === word.charAt(i)) {
        letters[i] = dummy;
        //cs == 0 ? score1++ : score2++
    }
    else {
             fail++;
             continue;
         }
}

Answer 2

You can always use "while" loop instead of "for" IE:

var n = 0;
var x = 0;

while (n < 3) {
  n++;
  x += n;
}

Answer 3

you have an syntax error fail++ (where is semicolon) tha is why it stops after if condition fails

for(i = 0; i < wLength; i++){
                        if(dummy === word.charAt(i)) {
                            letters[i] = dummy;
                            //cs == 0 ? score1++ : score2++
                        }
                        else {
                            fail++;

                        }
                    }

Answer 4

You can use a flag variable to achieve your requirement

let flag = true 
for (i = 0; i < wLength; i++) {
    if(dummy === word.charAt(i)) {
        letters[i] = dummy;
        //cs == 0 ? score1++ : score2++
    }else if (flag) {
        flag = false
    }
}
if (!flag) fail+=1
