jQuery append不工作使用json_encode

Question

我試圖從數據庫PHP插入追加結果使用echo json_encode（$ results）。 我是，從JSON中獲取所有來自帖子的值，但追加不起作用。

這裏是jQuery的一面：

$('#postsubmit').click(function(){ 
error = 0; 
// get form data 
post = $('#comments').val(); 
topicname = $('#topicName').val(); 
topicid = $('#topicID').val(); 
pageid = $('#pageID').val(); 
page = $('#page').val(); 
sendmail = $('#sendmail').val(); 
galleria_pointer = $('#galleria_pointer').val(); 
showstatus = $('#showstatus').val(); 
$(this).attr('disabled','disabled'); 

    if ($("#comments").val() == ''){ 
     $("#comments").css({ "border": "1px solid red"}); 
     $('.hideAdd').show(); 
     $(this).attr('enabled','enabled'); 

    } 

$.ajax({ 
    type: "POST",    
    url: "../foorumi/AjaxPost.php", 
    dataType: 'text', 
    data: "topicid="+topicid+"&pageid="+pageid+"&topicname="+topicname+"&page="+page+"&post="+encodeURIComponent(post)+"&sendmail="+sendmail+"&galleria_pointer="+galleria_pointer+ 
    "&showstatus="+showstatus, 
    beforeSend : function(){ 
    $("#loading_image").show(); 
    $("body").css("cursor", "wait"); 
    }, 
    error : function(XMLHttpRequest, textStatus, errorThrown){ 
    error = 1; 
    }, 
    success : function(data) {      
    $("#loading_image").hide(); 
    $("body").css("cursor", "default"); 

    //alert(data); 
     dataobject = $.parseJSON(data); 
     var json_post_result = dataobject.post_result; 
     var json_error_code = dataobject.errors; 
     var json_topicname = dataobject.topicname; 
     var json_postid = dataobject.postid; 
     var json_topicid = dataobject.topicid; 
     var json_pageid = dataobject.pageid; 
     var url = dataobject.url; 
     var json_showstatus= dataobject.showstatus; 
     var json_post = dataobject.post; 
     var json_dateNow = dataobject.sentNow; 
     var json_galleria_pointer = dataobject.sentNow; 
     var json_data_html = dataobject.data_html; 

     var decoded = $("<div/>").html(json_data_html).text(); 

     //alert(decoded); 
      if(json_post_result == true){ 
       url_to = url; 
       //window.location.replace(url_to); 

        $(".hideAdd").fadeOut("fast",function(){ 
        $('#ShowNew').show(); 
         $(".divWrapperAppend").append(decoded); 
        }); 

      } 

    } 
}); 
}); 

而這裏的PHP端：

$user_ = ($_SESSION['users_id']); 
$post_single = utf8_decode($_POST['post']); 
$pageid = $_POST['pageid']; 
$topicid_ = $_POST['topicid']; 
$topicname = $_POST['topicname']; 
$page = $_POST['page']; 
$galleria_pointer = ($_POST['galleria_pointer']); 
$sendmail = ($_POST['sendmail']); 
$showstatus = ($_POST['showstatus']); 
$microseconds_ = ((double) microtime()) * 1000000; 
$results = array(); 
$errors = ''; 
$data = array(); 

$sqluserinfo = "select u.username as username, u.userlevel, (SELECT 1 FROM userphotos up WHERE up.user_= '$user_' and defaultphoto = '1') as photonum 
,(SELECT count(1) FROM posts p1 WHERE u.users_id = p1.user_) as usermessagecount FROM users u WHERE u.users_id = '$user_'"; 
$sqlusersql = mysql_query($sqluserinfo); 
$username = mysql_result($sqlusersql, 0, username); 
$count_posts = mysql_result($sqlusersql, 0, usermessagecount); 
$ulevel = mysql_result($sqlusersql, 0, userlevel); 
$photonum = mysql_result($sqlusersql, 0, photonum); 


$userSendMailSQL = "select *, (SELECT 1 from mail_topic where sendmail = '1' and user_ = '$user_' and theader_ = '$topicid_') as sendmail1 FROM mail_topic WHERE user_='$user_' and theader_ = '$topicid_' order by id"; 
$resultsqlquery = mysql_query($userSendMailSQL)or die(mysql_error()); 
$sendMailto = mysql_result($resultsqlquery, 0, sendmail1); 


if ($post_single == "" || strlen(preg_replace('/\W/', '', $post_single)) < 5) 
{ 
    $errors = 1; 
} 
if (!empty($errors)){ 

$data['errors'] = $errors; 
$data['post_success'] = false; 
$results = array("errors"=>$errors, "post_result" => $data['post_success']); 
} 
else{ 

$data['post_success'] = true; 
$new_post = htmlspecialchars($post_single, ENT_QUOTES | ENT_SUBSTITUTE, 'ISO-8859-1'); 

$insert="insert into posts (topicID, user_, Post, editdate_, updatedmicrosec) values ('$topicid_','$user_','$new_post','editdate_','$microseconds_')"; 

    $timetoday = date("d.m.Y H:i:s"); 
    $dateNow = date_diff_as_text($timetoday,"now") . " sitten"; 

//Insert data to db 
mysql_query($insert); 


    $postid_ = mysql_insert_id(); 
if ($sendmail > 0){ 
    sendmail($topicid_,$topicname,$user_,$postid_,$page); 
} 
    updatelastread($topicid_); 

    $tableStyle_ajax = 'postStyleThisDay';

    $aid_ajax = '<a name="'.$postid_.'"></a>'; 
    $idcolor_ajax = 'color: #e82020; font-weight: bold;'; 
$borderbottom_ajax = 'border-bottom: 2px solid #e82020;';

    if ($photonum > 0) 
    {

echo json_encode($results); 

這是我想追加$ data_html，但它不會追加。 任何人都可以看到我做錯了什麼？

Answer 1

新增$data_html = utf8_decode($data_html)到PHP後，現在追加工作原理是:)
