Get Option Value Using Jquery for Multiple Tables

Hi I'm fairly new to js/php/html and am having an issue being able to pull data from the "action" column to check if the value is equal to "Closed." Basically, my code retrieves rows from a database and creates individual tables for each entry. Now I want to be able to write back into the db based upon whether the select="Closed." I've been doing a lot of research and I can't seem to find a method of being able to increment through the multiple tables to find the value of the select. Any help would be greatly appreciated. Thanks

<?php 
        
        $dbname='C:\Users\irgcbk\Documents\hotpartdb.mdb';
        $db = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$dbname; Uid='';         Pwd='';");
        
        $cnx=odbc_connect('ReceivingODBC', 'root', '');
        $sql="
        SELECT * 
        FROM HotPartLog 
        WHERE CompletionStatus is NULL ";
    $result=odbc_exec( $cnx, $sql); 
        $myarray=array();
        
        $i=0;

        While (odbc_fetch_into($result,$myarray)){
        
        /*foreach($myarray as $row){
                foreach($row as $key=> $value){*/            
        ?>
