php - Javascript subtotal function only working on first row of table -


i implementing shopping cart , have added subtotal field multiplies item quantity , price , returns subtotal in subtotal column.

but, javascript function calculating subtotal first row , not rows.

here code:

<td style="text-align: left; width: 80px;">pkr<input style="width: 70px;" type="number" id="price1" value="<?php echo $values["item_price"];?>" readonly ></td> <td style="text-align: center; width: 80px;"><br/><input style="width: 60px; " form="myform" type="number"  name="qty[<?php echo $values["item_id"]; ?>]" id="qty" value="<?php echo $values["item_quantity"];?>"></td> <td style="text-align: left; width: 80px;">pkr<input style="width: 70px; " form="myform" type="number" id="total" value="" readonly></td>  <script type="text/javascript">   var price1=document.getelementbyid("price1").value;    function calculate1() {         var quantity1 = document.getelementbyid("qty").value;     var x = price1 * quantity1;     document.getelementbyid("total").value = x;           } </script>

note: i'm calling calculate() function on onload event in <body> tag.

if fields readonly - set total value php , remove javascript function:

<input      style="width: 70px; "      type="number"      value="<?php echo ($values["item_quantity"] * $values["item_price"]) ?>"      readonly>
