javascript for (i = 0; i < XXX.length; i++) -> length question
- by Fernando SBS
for (m = 0; m < troopsCount.length; m++) {
//FM_log(7,"i="+i+" m="+m);
//FM_log(7,"tipoTropaPrioritaria[m] = "+tipoTropaPrioritaria[m]);
//FM_log(7,"troopsCount[m] = "+troopsCount[m]);
//FM_log(7,"availableTroops[m] = "+availableTroops[m]);
if ((tipoTropaPrioritaria[m] == null || tipoTropaPrioritaria[m] == "undefined")
|| (troopsCount[m] == null || troopsCount[m] == "undefined") ||
(availableTroops[m] == null || availableTroops[m] == "undefined"))
return "alternaTropas(): ERRO - tipoTropaPrioritaria[m] || troopsCount[m] || availableTroops[m] null ou undefined";
if ((parseInt(tipoTropaPrioritaria[m]) != 0) && (parseInt(troopsCount[m]) != 0)) {
naoServe = true;
break;
}
else {
if ((parseInt(availableTroops[m])) < (parseInt(troopsCount[m]))) {
naoServe = true;
break;
}
else if (m < troopsCount.length) {
naoServe = true;
}
else { //means m >= troopsCount.length
naoServe = false;
}
}
}
my question is: the last statement
else { //means m >= troopsCount.length
naoServe = false;
}
will it ever be evaluated since
for (m = 0; m < troopsCount.length; m++)
???
