我正在努力让人们的反应像Facebook一样(目前只是用文字(。所以我在Ajax工作，我的成功者不想成功，我的函数((给出了：我声明的"，但它的值永远不会被读取如果我用同样的设置检查另一个文档，它仍然继续，并且成功了，所以我不知道我错在哪里，也不知道目前的问题在哪里。
我的php代码(buddyChat.php(
<?php
session_start();
if (empty($_SESSION['user_id'])) {
header('Location: login.php');
}
//Hier mag enkel het gesprek te zien zijn tussen 2 users die met elkaar bevriend zijn
//tabel buddies >buddyID1 & buddyID2
include_once(__DIR__."/inc/header.inc.php");
include_once(__DIR__."/classes/Message.php");
include_once(__DIR__."/classes/User.php");
$userArray = $_SESSION['user_id'];
$userID = implode(" ", $userArray);
$currentUser = $userID;
//var_dump($_POST);
//$recipientID = implode(" ",$_POST);//om het getal terug te krijgen van de recipientID
$recipientID = $_POST['recipientID'];
//msg wordt in databank gestopt
if(!empty($_POST['message'])){
$msg = new Message();
$msg->setUserID($currentUser);
$msg->setRecipientID($recipientID);
$msg->setMessage(htmlspecialchars($_POST['message']));
$msg->writeMessage();
}
//msg wordt afgedrukt/gereturned
$messages = Message::messagePrint($currentUser,$recipientID);
$names = User::printRecipientName($recipientID);

和我的JS页面(reaction.JS(：
$(document).ready(function (){
$(".emoji").on("click", function() {
// de variabelen om te zien welke emoji je hebt en op welke post je zit
var emoji = $(this).attr("data-emoji");
//var msgID = $(this).attr("data-msgID");
console.log("here it works: " + emoji);
//ajax sturen voor het in de database te stoppen
$.ajax({
type: "POST",
dataType: 'json',
url: "ajax/Reaction.php",
data: "emoji=" + emoji,
succes: function (data){
console.log("succes");
$(".emoji_liked_text").html(emoji.toLowerCase()).removeClass().addClass('emoji_liked_text_'+emoji.toLowerCase()).addClass('active');
$(".emoji_liked_png").removeClass().addClass('emoji_liked_png').addClass('emoji_liked_' + data_reaction.toLowerCase());$(".reaction-btn-text").text(data_reaction).removeClass().addClass('reaction-btn-text').addClass('reaction-btn-text-' + data_reaction.toLowerCase()).addClass("active");
},
error: function(data){
console.log("didn't work");
}
})
console.log("this shows up after Ajax");
});
});
我使用了3个控制台日志：1个在ajax之前，1个在ajax内部，1个之后，只是为了检查发生了什么、什么时候发生，或者甚至发生了什么。他们按如下进行。1:ajax之前的1。2:ajax之后的1。3:ajax中的1。所以我至少得到了3个控制台日志。但是，如果我不使用">dataType:'json'"，它甚至不会显示ajax控制台日志。即使在另一个项目中，它也没有写">dataType"，而且它仍然有效，所以我真的不知道自己做错了什么。
看起来你真的必须检查一下你是如何写单词的。我把成功写成了成功。出了什么问题，这就是为什么它不想继续下去。。
我们学到了什么？看看你是怎么写的！但有第二只眼睛看着他们，看到的错误总是很好的
