Using JavaScript to develop web game rankings

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>

Copy after login

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 },
];

Copy after login

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);
  });
}

Copy after login

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

Copy after login

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!
