select option in each row of table. after gave inputs to that table, how can i get each row’s select tag value and its text in a for loop

its my size table script

function sizeadd()
{
    var mytable =  document.getElementById("sizenames");
    var rows = mytable.rows.length;

    var r1 = mytable.insertRow(rows);
    r1.id = mytable.rows.length-1;
    var c1 = r1.insertCell(0);
    var c2 = r1.insertCell(1);

    var checkbox = document.createElement("input");
    checkbox.type = "checkbox";
    var txtSizePop = document.createElement("select");
    txtSizePop.style.width = '100px';
    txtSizePop.className = 'txtSizeSelection';
    txtSizePop.id="txtSizePop"+r1.id;
    
    c1.appendChild(checkbox);
            
    <?php
        require('connection.php');
        $sqlSize = "select * from msize order by name asc";
        $rsSize = mysqli_query($con, $sqlSize); 
    ?>

    var sizeoption = document.createElement("option");
    sizeoption.value = "-1";
    sizeoption.text = "Select Size";
    txtSizePop.appendChild(sizeoption);
    c2.appendChild(txtSizePop);
    <?php while ($row = mysqli_fetch_array($rsSize)) { ?>
        var sizeoption = document.createElement("option");
        sizeoption.value = "<?php echo $row["code"]; ?>";
        sizeoption.text = "<?php echo $row["name"]; ?>";
        sizeoption.label = "<?php echo $row["name"]; ?>";
        txtSizePop.appendChild(sizeoption);
        c2.appendChild(txtSizePop);
    <?php } ?>
}

i am trying this table’s select tag value and text in other one script

function SizeUpdate()
{
var mystyletable4U = document.getElementById("sizenames");
var rows = mystyletable4U.rows.length;

for(var i = 1; i <= rows-1 ; i++)
    {  
    alert(i);
    var Rowid4Siz = mystyletable4U.rows[i].cells[1].children[0].value;
    var Label4Siz = mystyletable4U.rows[i].cells[1].children[0].text;
    }
