Javascript: 取亂算數, 練習寫一支js版的猜字遊戲

gistfile1.js

//JS取亂數可以靠random()這方法，回傳是0~1以內的隨機小數
Math.random();

//設定可以取回指定範圍內亂數

function useFloor(min,max){
  return Math.floor(Math.random()*(max-min+1)+min);
}

function useCeil(min,max){
  return Math.ceil(Math.random()*(max-min+1)+min-1)
}

function useRound(min,max){
  return Math.round(Math.random()*(max-min)+min)
}

//隨機取陣列中的值

var myArray = new Array("A","B","C","D");
var randomGet = myArray[Math.random()*myArray.length];


//即興發揮，大家看看就好，請不要批我～！

var words = ["潤娥","孫藝珍","新垣結衣","戶田惠梨香"]
var anwser = words[Math.floor(Math.random()*words.length)];
while(reponse= prompt("請輸入 1:潤娥,2:孫藝珍,3:新垣結衣,4:戶田惠梨香 其中一人名字")){
  if(reponse == anwser){
    alert("Congratulation! You're a fucking genius,aren't you?");
    break;
  }
  else{
    alert("Haha, you're moron!, just take another shoot!");
  }
}
alert("The anwser is: "+anwser);
