how to pass values inside javascript function along with this

Question

This is my code where I pass value:

echo '<td style="width:10px;" ><input type="text" name="qty__'.$product_name.'" id="qty__'.$product_name.'"  onkeyup="total_amounts(this,'.$product_name.');"  /></td>';

i just only want onkeyup function take this and also product name which will be used in below code

<script>
   function total_amounts(qty,product_id)
 {   
 alert('hi');
var product_id = document.getElementById("discount1").value;

   alert(product_id);
 var price1 = document.getElementById("price1__"+product_id).value;
  var discount1 = document.getElementById("discount1__"+product_id).value;
 alert(discount1);

    document.getElementById('net_price').value = price1;

    }
  </script>

but the problem is I have not received the product name inside the script.

Is the DOM rendered like you have expected?

Why do you pass this without using it?

Maybe you are forgetting to put strings in quotes?

Escaping ' by using a backslash \' allows you to do this.

onkeyup="total_amounts(this,\''.$product_name.'\');"
