Php使用JQUERY AJAX的相似和不同之处

我对我的帖子有一个问题。问题是当我点击.like_button时，<span id='you"+New_ID+"'><a href='#'>You</a> like this.</span>没有显示。

我仍然在浏览器开发者控制台上查看。但当我点击点赞按钮时，点赞按钮会改变，但<span id='you"+New_ID+"'><a href='#'>You</a>, </span>没有显示。但如果我刷新页面，<span id='you"+New_ID+"'><a href='#'>You</a>, </span>就会出现。

有人能帮我吗？

我正在使用此代码进行LIKE和UNLIKE：

AJAX查询：

$('.like_button').die('click').live("click", function () {
    var KEY = parseInt($(this).attr("data"));
    var ID = $(this).attr("id");
    if (KEY == '1') {
        var sid = ID.split("likes");
    } else {
        var sid = ID.split("like");
    }

    var New_ID = sid[1];
    var REL = $(this).attr("rel");
    var URL = $.base_url + 'post_like_ajax.php';
    var dataString = 'post_id=' + New_ID + '&rel=' + REL;
    $.ajax({
        type: "POST",
        url: URL,
        data: dataString,
        cache: false,
        success: function (html) {
            if (html) {
                if (REL == 'Like') {
                    $("#elikes" + New_ID).show('fast').prepend("<span id='you" + New_ID + "'><a href='#'>You</a> like this.</span>");
                    $("#likes" + New_ID).prepend("<span id='you" + New_ID + "'><a href='#'>You</a>, </span>");
                    $('#' + ID).html('Unlike').attr('rel', 'Unlike').attr('title', 'Unlike');
                } else {
                    $("#elikes" + New_ID).hide('slow');
                    $("#you" + New_ID).remove();
                    $('#' + ID).attr('rel', 'Like').attr('title', 'Like').html('Like');
                }
            }
        }
    });
    return false;
});

PHP代码：

<?php

}
$i=$i+1;
}
if($post_like_count>3)
{
$post_like_count=$post_like_count-3;
echo ' and <span id="like_count'.$post_id.'" class="numcount">'.$post_like_count.'</span> others like this.'; 
}
else
{
echo ' like this.'; 
}
echo '</div>';
}
}

echo '<div class="likes" id="elikes'.$post_id.'" style="display:none"></div>';
}
?>

post_like_ajax.php

<?php
