我正在尝试在网站上构建一个非常简单的积分计数器。数字和按钮按下没有显示在主 HTML 中。我对 javascript 比较熟悉，但不知道如何在网站上实现它。帮忙？
我试过将 javascript 放在 header 的标记中，但它仍然没有显示。
<html>
<head>
<link rel="stylesheet" href="style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="/public_html/script.js"></script>
</head>
<body>
<div id="main-container">
<div class="health-box" id="opponent-health">
<img src="https://www.trzcacak.rs/myfile/full/208-2086167_runic-letter-othalan-rune-odal.png">
<div class="health-counter" id="opponent-health-counter">
</div>
<div class="health-adjust health-minus" id="opponent-health-minus">
▼
</div>
<div class="health-adjust health-plus" id="opponent-health-plus">
▲
</div>
</div>
<div class="health-box" id="your-health">
<p> LP </p>
<div class="health-counter" id="your-health-counter">
</div>
<div class="health-adjust health-minus" id="your-health-minus">
▼
</div>
<div class="health-adjust health-plus" id="your-health-plus">
▲
</div>
</div>
</div>
</body>
</html>
$(document).ready(function() {
//Variable set-up
var opponentHealth = 0;
var yourHealth = 10;
$("#opponent-health-counter").html(opponentHealth);
$("#your-health-counter").html(yourHealth);
//Health adjust code
$(".health-adjust").click(function() {
if (this.id == "opponent-health-minus" && opponentHealth > 0) {
opponentHealth -= 1;
}
else{
opponentHealth -= 0;
};
if (this.id == "your-health-minus") {
yourHealth -= 1;
};
if (this.id == "opponent-health-plus" && opponentHealth < yourHealth) {
opponentHealth += 1;
}
else{
opponentHealth += 0;
};
if (this.id == "your-health-plus") {
yourHealth += 1;
};
$("#opponent-health-counter").html(opponentHealth);
$("#your-health-counter").html(yourHealth);
});
});
这是指向 Pen 的链接，其中的编程按预期工作。 https://codepen.io/iph33r/full/LYPpOJm
最佳答案
由于您的脚本使用了 Jquery，因此您需要先加载它。
<head>
<link rel="stylesheet" href="style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="/public_html/script.js"></script>
</head>
