Response from PHP to JS doesn't work after switching to JQuery – PHP Versions

So, I am developing my own blog type of website, and I bumped into a problem recently while trying to get rid of JS from my code. So I have show.js and showpost.php. Here is my JS code that was showing blog posts while I was using ajax js:

  load: function () {
    posts.ajax({ req: "show" }, function () {
      document.getElementById("cwrap").innerHTML = this.response;
    });
  },

everything worked just fine. But when I tried to replace that with a JQuery version

jQuery.ajax({
  type: "GET",
  url: 'app/showpost.php',
  dataType: 'text',

  success: function (data) {
    console.log(data);
    console.log("okokok");
    document.getElementById("cwrap").innerHTML = this.response;           
  }
});

it doesn’t work how it’s intended!
Now to explain how my showpost.php file works:

<?php
include_once 'config.php';
echo('');
try {
    $stmt = $pdo->prepare("SELECT `name`, `likes`,`imagename`,`comment_id`, `timestamp`, `message` FROM `posts` WHERE `post_id`=? ORDER BY `timestamp` DESC");
   $stmt->execute([$_POST['pid']]);

  } catch (Exception $ex) {
    die($ex->getMessage());
  }

  while ($r = $stmt->fetch(PDO::FETCH_NAMED)) { 
?>
<div id="post" style="box-shadow: 0 .15rem 1.75rem 0 rgba(58,59,69,.15)!important;">
<button id="<?=$r['comment_id']?>" name="like" class="btn" style="  float: right;" action="likepost.php" method="post"><svg xmlns="http://www.w3.org/2000/svg" enable-background="new 0 0 24 24" height="24" viewBox="0 0 24 24" width="24"><g><rect fill="none" height="24" width="24" y="0"/></g><g><g><path d="M13.12,2.06L7.58,7.6C7.21,7.97,7,8.48,7,9.01V19c0,1.1,0.9,2,2,2h9c0.8,0,1.52-0.48,1.84-1.21l3.26-7.61 C23.94,10.2,22.49,8,20.34,8h-5.65l0.95-4.58c0.1-0.5-0.05-1.01-0.41-1.37C14.64,1.47,13.7,1.47,13.12,2.06z M3,21 c1.1,0,2-0.9,2-2v-8c0-1.1-0.9-2-2-2s-2,0.9-2,2v8C1,20.1,1.9,21,3,21z"/></g></g></svg></button>
  <date><?=$r['timestamp']?></date>
  <h4>Bugs: <?=$r['likes']?></h4>
  <h3><?=$r['name']?></h3>
  <div class="message">
    <?=$r['message']?>
  </div>
  <img src="static/<?=$r['imagename']?>"> 
  </div>
 
  <?php }
  $stmt = null;
  $pdo = null;  
?>

as you can see, its a Php file with a little of html. It worked fine when I was using Xhr, but now with Jquery it doesn’t work! Please help!

EDIT: document.getElementById("cwrap").innerHTML = data; doesn’t change anything, it might be a problem of my showpost.php not sending out the html part.

    datatype needs to be html or json

    jQuery.ajax({
  type: "GET",
  url: 'app/showpost.php',
  dataType: 'HTML',

  success: function (data) {
    console.log(data);
    console.log("okokok");
    document.getElementById("cwrap").innerHTML = this.response;           
  }
});

    The problem is here in your success(data) callback function.

      document.getElementById("cwrap").innerHTML = this.response;

    You are getting data but you are using this.response which is going to be undefined because there is no such variable defined. Also the dataType in ajax call should be html i.e., dataType : 'html',.
    So it should be like:

    jQuery.ajax({
  type: "GET",
  url: 'app/showpost.php',
  dataType: 'html',
  
  success: function (data) {
    console.log(data);
    console.log("okokok");
    document.getElementById("cwrap").innerHTML = data;           
  }
});
