Supose我有一個調用相同功能的兩倍，與型動物功能各時間參數，有些是這樣的：用不同的參數調用同一個函數兩次
function one(){
two(a,b);
two(c,d);
}
當我打電話的功能之一，只有第一個功能兩個被執行，但不是第二個。有沒有一種方法只用Javascript來做到這一點？ （不是jQuery的）
下面是cuestion代碼（是有點基於文本的RPG）

（出於某種原因，它不工作的jsfiddle）。問題在於功能戰。
function battle (hero, monster){
if(hero.alive===true && monster.alive===true){
var heroIniciative = Math.floor(Math.random()*20)+1;
var monsterIniciative = Math.floor(Math.random()*20)+1;
var attacker;
var defender;
var attackerInfo;
var defenderInfo;
/*INICIATIVE ROLL*/
if (heroIniciative >= monsterIniciative){
attacker = hero;
defender = monster;
attackerInfo = heroInfo;
defenderInfo = monsterInfo;
textInfo.value += attacker.name + " attacks first!: " + heroIniciative + " vs " + monsterIniciative + "\n";
textInfo.scrollTop = textInfo.scrollHeight;
attack(attacker, defender, attackerInfo, defenderInfo);
attack(defender, attacker, defenderInfo, attackerInfo);
}
else {
attacker = monster;
defender = hero;
attackerInfo = monsterInfo;
defenderInfo = heroInfo;
textInfo.value += attacker.name + " attacks first!: " + monsterIniciative + " vs " + heroIniciative + "\n",
textInfo.scrollTop = textInfo.scrollHeight;
attack(attacker, defender, attackerInfo, defenderInfo);
attack(defender, attacker, defenderInfo, attackerInfo);
}
check_defeat(attacker, defender, attackerInfo, defenderInfo);
}
else {reset (hero, monster);
}
}
當我打電話時，它只是執行第一次函數攻擊，而不是第二次函數攻擊。
buttonAttack.onclick = function(){
if (current_monster.hitPoints <= 0){current_monster = selectMonster();monsterInfo.value = current_monster.stats() + "\n" + "Alive: " + current_monster.alive;}
else{battle(Arquer, current_monster);}
};
是的，你是賴特。我錯誤地在帖子中輸入（發生這種情況時沒有簽入），但是在我的代碼中正確寫法，正如你所說的那樣。我編輯我的帖子，我希望你現在可以更清楚地看到問題。 – Paul
