I have created a simple product inventory control form using query.
It consists of(product name, price, qty, amount) after filling all the fields and clicks add button all details it will append on the table row successfully.
After adding the price one by one, finally calculate and display the final total successfully.
I put the delete button next to the product.
Hitting delete
button on particular row will be delete it successfully, but the final total amount didn't reduce once I delete the product from the product table.
I don't know how to reduce the price what I tried so far. i wrote it below. can anyone go through the code and give the good solution for it?
Form
<tr>
<th>Product Code</th>
<th>Product Name</th>
<th>Price</th>
<th>Qty</th>
<th>Amount</th>
<th style="width: 40px">Option</th>
</tr>
<tr>
<td>
<input type="text" class="form-control" placeholder="barcode" id="barcode" name="barcode" required>
</td>
<td>
<label id="pro_name" name="pname" id="pname"></label>
<input type="text" class="form-control" placeholder="barcode" id="pname" name="pname" >
</td>
<td>
<input type="text" class="form-control pro_price" id="pro_price" name="pro_price"
placeholder="price" >
</td>
<td>
<input type="number" class="form-control pro_price" id="qty" name="qty"
placeholder="qty" min="1" value="1" required>
</td>
<td>
<input type="number" class="form-control" placeholder="total_cost" id="total_cost" name="total_cost">
</td>
<td>
<button class="btn btn-success" type="button" onclick="addproduct()">Add

</td>
