Question

我已经将此代码作为示例来创建基本的JavaScript测验：

var Question = function(id, text, correct, incorrect) {
    this.id = id;
    this.text = text;
    this.correct = correct;
    this.isCorrectlyAnswered = false;
    this.all = incorrect;
    this.all.push(correct);
    this.all.sort(randomSort);
}

Question.prototype.write = function() {
    var qu = document.getElementById("questions");
    qu.innerHTML += "<p>"+this.text+"</p>";

    var questionList = "<ul class='questionlist'>";
    for (var i=0; i<this.all.length; i++) {
        if ( this.all[i] == this.correct ) {

            questionList += "<li><label onclick='right("+this.id+")'><input type='radio' name='"+this.id+"'>"+this.all[i]+"</input></label></li>";

        } else {

            questionList += "<li><label onclick='wrong("+this.id+")'><input type='radio' name='"+this.id+"'>"+this.all[i]+"</input></label></li>";
        }
    }
    questionList += "</ul>";
    qu.innerHTML += questionList;
}

我对此感到困惑。任何人都可以帮助我将代码分解为“可理解的”块吗？

Answer 1

该代码定义了一个用于面向对象编程的Javascript类。你可以说

 var q = new Question(.......);

使用合适的参数，并调用函数

 q.write();
