With the development of the Internet, web games occupy an increasingly important position in people's lives. In order to enhance competition and interaction between players, developing a web game ranking has become an essential function. This article will introduce how to use JavaScript to develop a simple web game ranking list and provide code examples.

First, we need to create a container containing the leaderboard in the HTML file. You can use an unordered list (

<!DOCTYPE html>
<html>
<head>
  <title>游戏排行榜</title>
</head>
<body>
  <h1>游戏排行榜</h1>
  <ul id="leaderboard"></ul>
</body>
</html>

Next, we need to write code in a JavaScript file to dynamically add data to the leaderboard. First, we need to create an array to hold each player's score data. The following is an example array initialization:

const leaderboardData = [
  { name: '玩家A', score: 100 },
  { name: '玩家B', score: 90 },
  { name: '玩家C', score: 80 },
];

Then, we can write a function to sort the array according to the score and update the HTML content of the leaderboard to the sorted data. The code is as follows:

function updateLeaderboard() {
  leaderboardData.sort((a, b) => b.score - a.score); // 按照分数从高到低排序

  const leaderboard = document.getElementById('leaderboard');
  leaderboard.innerHTML = ''; // 清空排行榜内容

  leaderboardData.forEach((player, index) => {
    const listItem = document.createElement('li');
    listItem.innerHTML = `${index + 1}. ${player.name}: ${player.score} 分`; // 显示玩家名字和分数
    leaderboard.appendChild(listItem);
  });
}

Finally, we need to call the updateLeaderboard function to update the content of the ranking list. You can set a timer to automatically update the rankings after a certain interval. For example, the following code can update the leaderboard every 30 seconds:

setInterval(updateLeaderboard, 30000); // 30秒钟更新一次排行榜

In actual applications, we can obtain real-time player score data through interaction with the backend server, and then update the leaderboard. In this way, we can implement a dynamic and real-time web game ranking list.

To summarize, through the introduction of this article, we have learned how to use JavaScript to develop a simple web game ranking list. By dynamically adding data and updating HTML content, we can implement a function that tracks player scores and display it on the page. Hope this article helps you!
