只需阅读 Jquery 的文档：

jQuery

这只不过是一个翻转效果，以及一个等待更新数据库条目的地址。它并不是真正的 jQuery。其中的“核心”将是您的数据库和服务器端脚本。

$("a.voteup").click(function(){
  $.get("updatescore.php", {"id":"112","score":"1"}, function(response){
    /* Do something with the response */
  });
});

该代码可能有点偏离，但它足以表达要点。从那里，您将有一个服务器端脚本等待接收此内容：

PHP / MySQL

重要：不要按原样使用。仅供演示。
ASP.NET：从您过去的问题中我注意到您可能正在使用 .NET 技术。这里完成的过程仍然是失败的相似。您将处理传入的请求，要求用户登录，他们的分数为 1 或 -1，以及您希望的任何其他内容。

  session_start();
  $userid = $_SESSION["userid"];

  $vote = $_GET["score"]; /* Limit to 1 or -1 */
  $article = $_GET["id"];

  /* Whatever is printed here will be the 'response' variable
     over in our jQuery callback function. Ideally, this function
     would only allow the vote if the following are true:
       1. User has not yet voted on this article
       2. Score is 1 or -1
       3. Voting is enabled on this article
       4. User is indeed logged in */
  print castVote($article, $vote, $userid);

?>

jQuery

This is nothing more than a roll-over effect, and an address that waits to update a database entry. It's not really jQuery. The "meat" of this would be your database and server-side scripting.

$("a.voteup").click(function(){
  $.get("updatescore.php", {"id":"112","score":"1"}, function(response){
    /* Do something with the response */
  });
});

That code may be a bit off, but it's close enough to convey the point. From there, you would have a server-side script waiting to receive this:

PHP / MySQL

IMPORTANT: Do not use as-is. Only for demonstration.
ASP.NET: I noticed from your past questions you are likely working within the .NET technologies. The process done here will still be faily similar. You'll handle the incoming request, require the user to be logged in, their score to be 1 or -1, and whatever else you wish.

  session_start();
  $userid = $_SESSION["userid"];

  $vote = $_GET["score"]; /* Limit to 1 or -1 */
  $article = $_GET["id"];

  /* Whatever is printed here will be the 'response' variable
     over in our jQuery callback function. Ideally, this function
     would only allow the vote if the following are true:
       1. User has not yet voted on this article
       2. Score is 1 or -1
       3. Voting is enabled on this article
       4. User is indeed logged in */
  print castVote($article, $vote, $userid);

?>
