I want to be able to calculate subtotal by multiplying quantity and price
but I cant because
*var quantity = parseInt("{{=details.quantities[index]}}");* in the
code below carries the value of 1 and it does not change. Please assist me
identify what could be wrong here and how can i rectify it?
*Model:*
db.define_table('client_order'),
Field('quoted_item','list:string', required=True),
Field('quantities','list:string', required=True))
*View:*
{{for index, (item, qty) in enumerate(zip(details.quoted_item,
details.quantities)):}}
<tr>
<td>{{=item}}</td>
<td><input type="text" onchange="calculateSubtotal(this,
{{=index}})" /></td>
<td>{{=qty}}</td>
<td><span id="subtotal{{=index}}"></span></td>
</tr>
{{pass}}
<script>
function calculateSubtotal(input, index) {
var price = parseFloat(input.value);
* var quantity = parseInt("{{=details.quantities[index]}}");*
var subtotal = parseFloat(price * quantity);
document.getElementById("subtotal" + index).innerHTML =
subtotal.toFixed(2);
updateGrandTotal();
console.log(parseFloat("{{=details.quantities[index]}}"));
}
</script>
