Calculating total price by iterating in the table using JavaScript


Calculating total price by iterating in the table using JavaScript

it should still fix some issue I'm working on an exercise where we have to build a shopping cart using HTML and JavaScript.
code :
function calculate(){
var table=document.getElementById('shopTable');
var count = table.getElementsByTagName('tr').length;
if (count > 0)
  {
    var total = 0;
    for(var i = 1; i < count; i++)
      {
        total += table.rows[i].cells[1].innerHTML * table.rows[i].cells[2].children[0].value;
      }
  }

alert(total);
}

wish of those help i hope you want this
first set the variable $total_products and $total_price
code :
$total_products = 0; // set to 0 initially
$total_price = 0; // set to 0 initially

    $count = 0;
        foreach ($products as $key => $product){
          $number = isset($_POST[$key])?$_POST[$key]:'';
                if (!$number){
                $count++;
                echo "";
                } else {
            echo "<tr>";
                echo "<td>";
                    echo $product;
                echo "</td>";
                echo "<td>";
                    echo $number;
                echo "</td>";
                echo "<td>";
                    $price = $prices[$count]* $number;
                    echo "&#8364 ", $price;
                echo "</td>";
            echo "</tr>";

            $total_products += 1; // update total_products +1
            $total_price += $price;  // update total_price +$price
            $count++;
            }
        }
echo "<tr>";
    echo "<td>";
        echo "Totaal";
    echo "</td>";
    echo "<td>";
        echo $total_products;
    echo "</td>";
    echo "<td>";
        echo $total_price;
    echo "</td>";
echo "</tr>";

To fix this issue You need a method with some kind of a loop over all your input fields, just like the one you created for one field, and trigger the call each time one field is updated:
code :
function getTotalPrice() {
  var total = 0,
      inputs = document.getElementsByTagName('input');
  for (var i = 0; i < inputs.length; i++) {
    if(inputs[i].value) {
      total += parseFloat(inputs[i].getAttribute("data-unitPrice")) * 
               parseInt(inputs[i].value,10);
    }
  }
  if(total > 0) {
    document.getElementById('TARGET').innerText = '\u20ac ' + total.toFixed(2);
  }
}

may help you . From what I can tell from your code snippets, you want to populate the total fields. I made a minimal reproducible example based off of your code. I added id attributes to the input tags and I added a calculate button which does the math to calculate the totals for the fields. Hopefully this can get you on the correct path for you to just take what I have here and apply it to your code.
code :
$(document).on('click','#calc', function(){
	var qty2 = $('#qty2').val();
  var length = $('#length').val();
  var temp = qty2 * length;
  var qty = $('#qty').val(temp).val();
  var price = $('#price').val();
  $('#totalNum').val(qty*price);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id ='tab_logic'>
<thead>
      <tr>
        <th class="text-center"> # </th>
        <th class="text-center"> Product </th>
        <th class="text-center"> Width </th>
        <th class="text-center"> Length </th>
        <th class="text-center"> Qty </th>
        <th class="text-center"> Total(m) </th>
        <th class="text-center"> Price Rate </th>
        <th class="text-center"> Total Price </th>
      </tr>
    </thead>
    <tbody>
      <tr id='addr0'>
        <td>1</td>
        <td><input type="text" name='product[]'  placeholder='Enter Product Name' class="form-control"/></td>
        <td><input type="text" name='width[]'  placeholder='Enter Product Name' class="form-control"/></td>
        <td><input id="length" type="number" name='length[]'  placeholder='Enter Product Name' class="form-control"/></td>
        <td><input id="qty2" type="number" name='qty2[]'  placeholder='Enter Product Name' class="form-control"/></td>
        <td><input id ="qty" type="number" name='qty[]' placeholder='Enter Qty' class="form-control" step="0" min="0"/></td>
        <td><input id="price" type="number" name='price[]' placeholder='Enter Unit Price' class="form-control" step="0.00" min="0"/></td>
        <td><input id="totalNum" type="number" name='total[]' placeholder='0.00' class="form-control total" readonly/></td>

Hope this helps Try if - if instead of if-else if.
if - else if condition is satisfied, the appropriate statements are executed and the remaining conditions are not evaluated.
