javascript评分函数学校作业

如何解决javascript评分函数学校作业

我一直在为我的学校作业使用 javascript 函数而苦苦挣扎。我正在尝试制作一个积分系统并首先在我的索引页面上对其进行测试。应该发生的事情是，当我按下左侧的按钮时，它应该重新启动游戏并要求输入一个有效的用户名，但右侧的按钮应该奖励 12 分，第一次单击时有效，但再次单击时它会保持打开状态十二。我在有人帮忙之前问过这个问题，但在我看到它之前，问题已被删除，所以我无法问如何完全解决它。

我的 html 索引页：

<html>
<head>
<title> Index </title>
<script src="main.js"></script>

</head>

<body>
<center><font size="200" color="white">Treasure hunt</font>
<br>
<br>
<p style="padding: 10px; border: 2px solid black;">
<font size="5" color="white">
Hello and Welcome to the Treasure Hunt!
<br>
You are a treasure hunter,beware there are false links,which are obvIoUs,and there are true links which are hidden. 
<br>
The wrong link will lead you Nowhere,the right link will lead you to the treasure.
<br>
 Also You have limited lives,so don't keep clicking on those obvIoUs links.

False links that take you in a circle (wrong turns)
<br>
Hidden links which take you to the next stage
<br>
Whenever you take a wrong turn(<a href="page1.html"><font color="white">bad link </a>  )you will be penalized (losing lives)
</font>
</p>


<br>
<a href="page2.html"><font size="50">click here quick to go to the next page!</font>  </a>
<br>
<br>
<button onclick="reset(); askName();"></button>
<button onclick="winPoints()"></button>
<body background="thc.JPG">
</body>
</html>

这是我的javascript函数页面：

function askName () {
 
    var name = window.prompt ("Arrr what be your name? ");


    sessionStorage.setItem("username",name);

}


function reset() {
    sessionStorage.setItem ("score",0);
    sessionStorage.setItem ("lives",3);
    sessionStorage.setItem ("username","");
}

function winPoints(points) {
    var pointsToWin = parseInt("12");

    var currentscore = +sessionStorage.getItem("score");

    if (currentscore == 0) {
        sessionStorage.setItem ("score",pointsToWin + currentscore);
        alert("You have " + pointsToWin + " points");
    } else {
        sessionStorage.setItem ("score",currentscore + pointsToWin);
        alert("You have " + currentscore + " points");
    }
}

提前致谢

解决方法

将此用于您的 winPoints javascript 函数。

function winPoints() {
    let currentScore = Number(sessionStorage.getItem("score"));
    sessionStorage.setItem("score",currentScore+=12);
    alert("You have " + currentScore + " points");
}
