javascript - 如何创建一个循环来显示还有多少问题需要回答？

Question

我正在尝试将此代码转换为循环:

var questions = 3;
var questionsLeft = '[ ' + questions + ' questions left]';
var question1 = prompt('Whats your name? ' + questionsLeft);
questions -= 1;
var questionsLeft = '[ ' + questions + ' questions left]';
var question2 = prompt('Whats your age? ' + questionsLeft);
questions -=1
var questionsLeft = '[ ' + questions + ' questions left]';
var question3 = prompt('Whats your dogs name? ' + questionsLeft);

所以，我这样做了:

var question1;
var question2;
var question3;
var questions = 3;

for(var i = 0; i < questions; --questions) {
    var questionsLeft = '[' + questions + ' questions left]';

    if (questions == 3) {
        question1 = prompt('Whats your name? ' + questionsLeft);
    } 
    if (questions == 2) {
        question2 = prompt('Whats your age ' + questionsLeft);
    }
    if (questions == 1) {
        question2 = prompt('Whats your dog\'s name? '  + questionsLeft);
    }
}

我认为这是错误的方式，对吗？我怎样才能做到正确？

更新:

var question = ['Whats your name? ', 'Whats your age?', 'Whats your color?'];
var questions = 3;

for(var i = 0; i < questions; i++) {
        var questionsLeft = ' [' + questions + ' questions left]';
        alert(question[i] + questionsLeft);
}

现在它回来了:

你叫什么名字？ [还剩3个问题]你几岁？ [还剩2个问题]停止

Answer 1

为什么不简单地使用像这样的数组:

questions=["Whats your name?","Whats you age?","Whats your dog\'s name?"];
answers=[]
for (i=0; i<questions.length; i++) {
       var j=3-i;
       var questionsLeft = '[' + j + ' questions left]';
       answers.push(prompt(questions[i] + " "+ questionsLeft));
}

您在 answers 数组中得到了所有答案。
