使用Jquery和Smarty在HTML中具有唯一的span id

使用Jquery和Smarty在HTML中具有唯一的span id,jquery,html,smarty,Jquery,Html,Smarty,我在jQuery上有一个问题投票系统,它可以完美地工作: $(".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({

我在jQuery上有一个问题投票系统,它可以完美地工作:

$(".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{
                       }
                }
           });
    }
)
这是它的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>
{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}
这是它的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>
{if isset($allanswers) eq True} {section name=res loop=$allanswers}</p>
<div text-align:center;><p> {$allanswers[res].answer_text} </p>

{else}
<p>{$allanswers[res].answer_total_rate}</p>
{/if}
{if isset($allanswers)eq True}{section name=res loop=$allanswers}

{$allanswers[res].答案_text}

{if isset($smarty.session.username)eq True} {$allanswers[res].答案_总_比率}

{else} {$allanswers[res].答案_总_比率}

{/if}
我的问题是,如果有多个答案,用户向上投票第n个答案,只有第一个数字的投票改变,第n个答案的投票不变。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

首先要使您的
span
id
唯一。通过执行以下操作

{$allanswers[res].答案{u总费率}

然后在你的电话里

$(".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,您有多个ID具有相同的名称
应答投票
,因为这是在循环中创建的(如果我没有错的话),所以它正在更新第一个ID

您最好将id更改为类或使其唯一..因为具有相同id的多个元素是无效的,可能会给您带来问题(您现在面临的问题)

尝试此操作(在此处将id更改为类)

{$allanswers[res].答案{u总费率}
还有你的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{
                   }
            }
       });
}
)
$(.a_upvote”)。单击(函数()
{
var$this=$(this)//
