How to get selected row values from a dynamic html table using JQuery?

Question

I have a html table dynamically populated from a database using laravel framework.

I have put a checkbox in the row header and a Save Entry button. I want to get only the checked row values of the table including the footer of the table which indicate the calculation summary.

something like this:

arrbreakdown = []; //push here the checked row values.
arrsummary = []; //push here the calculation summary.

Reproducible example:

<table class="table table-bordered" id="purchasetable">
    <thead>
        <tr>
            <th colspan="7" class="bg-secondary">
                Item Breakdown
            </th>
        </tr>
        <tr class="text-center">
            <th scope="col"><input type="checkbox" onclick="checkallcabin(this)" name="checkall"
                    id="checkall"> </th>
            <th scope="col">Item Name</th>
            <th scope="col">Description</th>
            <th scope="col">Qty</th>
            <th scope="col">UM</th>
            <th scope="col">Item Price</th>
            <th scope="col">Total Price</th>
            <script>
                function checkallcabin(bx) {
                    for (var tbls = $('#purchasetable'), i = tbls.length; i--;)
                        for (var bxs = tbls[i].getElementsByTagName("input"), j = bxs.length; j--;)
                            if (bxs[j].type == "checkbox")
                                bxs[j].checked = bx.checked;
                    setselect();
                }
            </script>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td> <input onchange="enablereqinfo()" id="row1" type="checkbox" name="dtrow"></td>
            <td>TEST 1</td>
            <td><input type="text" style="width:100%" value="TEST DESC 1"></td>
            <td>PCS</td>
            <td class="totalqty">5</td>
            <td><input type="number" step="0.01" style="max-width:100px;" value="0.00" onkeyup="calculateprice()" min="0"
                    class="iprice tnum" name="iprice"></td>
            <td class="totalprice text-right">0.00</td>
        </tr>
        <tr>
            <td> <input onchange="enablereqinfo()" id="row2" type="checkbox" name="dtrow"></td>
            <td>TEST 2</td>
            <td><input type="text" style="width:100%" value="TEST DESC 2"></td>
            <td>M</td>

                    class="iprice tnum" name="iprice"></td>
            <td class="totalprice text-right">0.00</td>
        </tr>
        <tr>
            <th colspan="6">Sub Total</th>
            <th class="text-right subtotal">0.00</th>
        </tr>
        <tr>
            <th colspan="6">Discount</th>
            <th class="text-right"><input style="max-width:100px;" onkeyup="calculatetotals()" type="number" value="0.00"
                    class="discount text-right"></th>
        </tr>
        <tr>
            <th colspan="6"></th>

                    for (var tbls = $('#purchasetable'), i = tbls.length; i--;)
                        for (var bxs = tbls[i].getElementsByTagName("input"), j = bxs.length; j--;)

You can loop through all checkboxes which is checked using each loop and then push the values of rows inside your array using .val() or .text()

Demo Code :

$("#save").click(function() {
  var arrbreakdown = []; //push here the checked row values.
  var arrsummary = []; //push here the calculation summary.
  //loop through checked checkbox
  $("tbody input[type='checkbox']:checked").each(function() {
    var selector = $(this).closest('tr'); //get closest row
    //push values in array
    arrbreakdown.push({
      "Name": selector.find('td:eq(1)').text(),
      "Description": selector.find('td:eq(2) input').val(),
      "Qty": selector.find('td:eq(3)').text(),
      "UM": selector.find('td:eq(4)').text(),
      "Item_Price": selector.find('.iprice').val(),
      "Total": selector.find('td:eq(6)').text()
    })

  })
  //for summary
  arrsummary.push({
    "Sub_Total": $(".subtotal").text(),
    "Discount": $(".discount").val(),
    "taxtotal": $(".taxtotal").text(),
    "netamount": $(".netamount").text(),
    "grandtotal": $(".grandtotal").text()
  })
  console.log(arrsummary)
  console.log(arrbreakdown)

})
