jQuery追加无法使用json_encode

Question

I'm trying to append an result from a database PHP insert using echo json_encode($results). I'm, getting all the values from the post back in the JSON but the appending is not working.

Here's the jQuery side:

$('#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); 
                   });

            }

  }
});
});

And here's the PHP side:

,(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{

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

echo json_encode($results);

It's the $data_html that I want to append, but it wont append. Can anyone see what I'm doing wrong?

console log ouput:

Answer 1

在PHP帖子中添加了$data_html = utf8_decode($data_html) ，现在追加按原样工作:)
