如何访问新创建的对象的变量?

How to access newly created object's variable?

所以我有这个蓝图对象:

function User (theName, theEmail) {
  this.name = theName;
  this.email = theEmail;
  this.quizScores = [];
  this.currentScore = 0;
}

我创建了一个像这样的新用户 var user1 = new User (theName.value, theEmail.value); 当用户输入他的姓名和电子邮件时,它位于事件侦听器的函数中。现在有问题和下一个问题的按钮。每次用户单击下一个问题按钮时,我想将 currentScore 增加一个。问题是它一直保持为 0。我是这样做的:

scoretag = document.createElement("p"); scoretag.innerHTML = user1.currentScore; body.appendChild(scoretag);

事件侦听器和主循环:

for (var i = 0; i < theChoices[question1.theChoices].length; i++) {

    var arrayQ = document.createElement("p");
    arrayQ.innerHTML = theChoices[question1.theChoices][i];
    list.appendChild(arrayQ);

    var radio = document.createElement("input");
    radio.type = "radio";
    listOptions.appendChild(radio);

    dbtn.addEventListener("click", function() {
        //list.removeChild(arrayQ);
        //listOptions.removeChild
        list.removeChild(list.firstChild);
        list.removeChild(list.lastChild);
        user1.currentScore = user1.currentScore+1;
        scoretag = document.createElement("p");
        scoretag.innerHTML = user1.currentScore;
        body.appendChild(scoretag);

      })
  }

更新:我在分数递增后将用于将子项附加到 body 元素的代码放在循环中,但这会导致页面上一个接一个地打印许多数字。

但是就像我说的,当我尝试在点击按钮时递增 1 时,它仍然在屏幕上显示 0。有帮助吗?

每次增加分数,都需要更新 HTML 元素。这是一个想法:

function User (theName, theEmail) {
  this.name = theName;
  this.email = theEmail;
  this.quizScores = [];
  this.currentScore = 0;
}
var user1 = new User ("aa","bb");

function updateScore(){
    user1.currentScore++;
    document.getElementById('score').innerText = user1.currentScore;
}
<button id="btn" onclick="updateScore()">next</button>
<p id="score">0</p>
