推荐答案

这无非是一个翻转效果，以及等待更新数据库条目的地址。这不是真正的jQuery。这样做的肉将是你的数据库和服务器端脚本。

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 */
  });
});

这code可能有点过，但它足够接近传达点。从那里，你将有一个服务器端脚本等待接收这样的：

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:

重要提示：不要使用原样。仅用于演示。
ASP.NET：我从你过去的问题，发现你很可能是内部的.NET技术工作。在这里完成这个过程仍然会faily相似。你会处理传入的请求，要求用户登录，他们的成绩为1或-1，并且你希望任何其他。     

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);

?>
