Hello my purpose is when i press the add button to add the second row after adding the first row
saving the first row to the database by going to method and increasing the second row. but when I press the add button, my data goes to the method without taking the values. How can I send the full values?

<form name="productForm" id="productForm"> <div class="table-responsive">
<table class="table table-bordered" id="articles">
<thead>
<tr style="text-align:center">
<th class="text-nowrap" style="text-align:center; vertical-align:middle;">Record No</th>
<th class="text-nowrap" style="text-align:center; vertical-align:middle;">Product Name</th>
<th class="text-nowrap" style="text-align:center; vertical-align:middle;">Product Code</th>
<th class="text-nowrap" style="text-align:center; vertical-align:middle;">Product Price</th>
<th class="text-nowrap" style="text-align:center; vertical-align:middle;">Add</th>
 </tr>
</thead>
 <tbody>
<tr class="ProductsRecords">
<td><input value=0 min="1" type="number" id="RECORDNO" name="[].RECORDNO" class="form-control name_list" /></td>
<td><input  type="text" id="PRODUCTNAME" name="[].PRODUCTNAME" class="form-control name_list" /></td>
<td><input type="number" id="PRODUCTCODE" name="[].PRODUCTCODE" class="form-control name_list" /></td>

<td><button type="button" name="add" id="add" class="btn btn-success" onclick="SaveMethod()" >Add</button></td>                                  
</tr>
</tbody>
</table>                                 
</div>
</form>

js.code

 var table = document.getElementById("articles");
 var array = $(table.rows[table.rows.length-1]).find("input");
 for (var j = 0; j < array.length; j++) { array[j].name = array[j].name.replace("[]", "[" + (table.rows.length - 1) + "]");
         }
      $.ajax({
        url: "SavePrice",          
        method: "POST",
        data: $('#productForm').serialize(),
        success: function (data) {
        }
 });

public PRICE SaveMethod(PRICE adding)
{
    /// adding properties not set value.
}
