我在jQuery上有这个问题投票系统,完美有效:

$(".q_upvote").click(function()
    {
        var vote = "vote_up";
        var question_id = this.id.split('_')[1];
        var votedata = "q_vote=" + vote+"&question_id="+question_id;
        $.ajax({                 
                type: 'POST',
                url: 'vote.php',
                data: votedata,
                success: function(vote_msg){
                   if($.trim(vote_msg) == 'ok')
                       {
                        $("#votenum").text( parseInt($("#votenum").text()) + 1 );                       }
                   else{
                       }
                }
           });
    }
)

这是HTML部分:

<p><span id="votenum">{$question_vote}</span> 
<a id="upvote_{$qid}" class="q_upvote" href="#"><i class="icon-thumbs-up"></i></a>

我也希望用答案做同样的事情。我写了这个:

$(".a_upvote").click(function()
    {
        var vote = "vote_up";
        var answer_id = this.id.split('_')[1];
        votedata = "q_vote=" + vote+"&answer_id="+answer_id;
        $.ajax({                 
                type: 'POST',
                url: 'vote2.php',
                data: votedata,
                success: function(vote_msg){
                alert(vote_msg)
                   if($.trim(vote_msg)== 'ok')
                       {
                        $("#answervotes").text( parseInt($("#answervotes").text()) + 1 );
                        }
                   else{
                       }
                }
           });
    }
)

这是HTML部分:

{if isset($allanswers) eq True} {section name=res loop=$allanswers}</p>
<div text-align:center;><p> {$allanswers[res].answer_text} </p>
{if isset($smarty.session.username) eq True}
<p><span id = "answervotes">{$allanswers[res].answer_total_rate}</span>
<a id="upvote_{$allanswers[res].answer_id}" class="a_upvote" href="#""><i class="icon-thumbs-up"></i></a>
<a id="downvote_{$allanswers[res].answer_id}" class="a_downvote" href="#" "><i class="icon-thumbs-down" ></i></a></p>
{else}
<p>{$allanswers[res].answer_total_rate}</p>
{/if}

我的问题是如果有几个答案并且用户提出第n个答案,只有第一个号码的投票改变,第n个答案的投票不会改变。我想我需要以某种方式使答案独特,但我不知道如何。我怎样才能解决这个问题? 谢谢。

首先,您将span id设为唯一。通过执行以下操作。

<p><span id = "answervotes{$allanswers[res].answer_id}">{$allanswers[res].answer_total_rate}</span>

然后在你的电话中

$(".a_upvote").click(function()
{
    var vote = "vote_up";
    var answer_id = this.id.split('_')[1];
    votedata = "q_vote=" + vote+"&answer_id="+answer_id;
    $.ajax({                 
            type: 'POST',
            url: 'vote2.php',
            data: votedata,
            success: function(vote_msg){
               if($.trim(vote_msg)== 'ok')
                   {
                    $("#answervotes" + answer_id).text( parseInt($("#answervotes"  + answer_id).text()) + 1 );
                    }
               else{
                   }
            }
       });
}

我在这里看到的是你有多个具有相同名称answervotes的ID,因为这是在循环中创建的(如果我没有错),所以它正在更新第一个...

您最好将您的ID更改为类或使其唯一..因为具有相同ID的多个元素无效并且可能会给您带来问题(您现在面临的问题)......

试试这个(在这里将id更改为类)

<p><span class= "answervotes">{$allanswers[res].answer_total_rate}</span>

和你的jquery

$(".a_upvote").click(function()
{
    var $this=$(this);  //<--here
    var vote = "vote_up";
    var answer_id = this.id.split('_')[1];
    votedata = "q_vote=" + vote+"&answer_id="+answer_id;
    $.ajax({                 
            type: 'POST',
            url: 'vote2.php',
            data: votedata,
            success: function(vote_msg){
            alert(vote_msg)
               if($.trim(vote_msg)== 'ok')
                   {
                    $this.siblings(".answervotes").text( parseInt($("#answervotes").text()) + 1 );  //<----here
                    }
               else{
                   }
            }
       });
}
)

使用siblings(),因为您的answervotes范围和upvote a位于同一个父<p>
