Refresh tag value with dynamically generated data

I have a main php page displaying dynamically generated cards through a loop. I am trying to refresh the content for certain tags, but it doesn't seem to work so far.

This is my main.php file:

<div class="col" style="width: ">
   <div class="card shadow-sm h-100 border-dark rounded" style="width: 240px; background-color: #ededed">
       <span class="mySpan">
           <div class="container">
               <input type="hidden" class="cardid" name="mycardId" value="
                <?php echo $cardId ?>" id="cardid">
               <div class="card-body px-0 py-0">
                   <table id="firstTable" class="table table-responsive-md table-striped table-borderless text-center mb-0" style="width: 237px; table-layout: fixed;">
                       <thead>
                           <tr>
                               <th colspan="3" id="row1field1" name="row1field1" class="text-center py-1 px-1 fw-bold 
                                    <?php if($selectField == "EXP") echo "text-decoration-line-through" ?>" style="max-width: 237px; text-transform: uppercase; font-size: 18px;" contenteditable="true" data-name="row1field1"> <?php echo $row1field1; ?> </th>
                           </tr>
                       </thead>
                   </table>

                   <table id="row4" class="table table-responsive-md table-striped table-borderless text-center mb-0" style="max-width: 238px; min-height: 50px; border: thin solid lightgray">
                       <tr>
                           <td name="row4field1" id="row4field1" class=" py-1" style="max-width: 104px; border-right: thin solid gray; text-transform: uppercase;" contenteditable="true">
                               <h6>
                                   <strong> <?php echo $row4field1; ?> </strong>
                               </h6>
                           </td>
                           <td name="row4field2" id="row4field2" class=" py-1" style="max-width: 104px; text-transform: uppercase;" contenteditable="true">
                               <h6>
                                   <strong> <?php echo $row4field2; ?> </strong>
                               </h6>
                           </td>
                       </tr>
                   </table>
               </div>
           <div>
       </span>
   </div>
</div>

This is what I've tried so far using javascript:

$(document).ready(function(){
    setInterval(function(){
        $("#row1field1").load(" #row1field1 > *");
    }, 5000);
});

Unfortunately, after the refresh, all content from row1field1 is gone. I believe this could be because the IDs are not unique, but I'm using the hidden value cardId to differentiate each card. Any advice on how to properly refresh these dynamic content is greatly appreciated.

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
