Hi all
Look at example pack "Master-Detail Form for Order Entry" on http://examples.codecharge.com/ExamplePack/OrderEntry/OrderEntry.php
How can force JavaScript to always show two decimal places for "Price" and "Total" as it is for "Unit Price", even if it is ex. 12.90 instead 12.9
This is javascript used in the page:
<script language="JavaScript" type="text/javascript">
function StrToFloat(str)
{
if (str.indexOf(",") != -1) {
str = str.replace(",",".");
}
var result = parseFloat(str);
if (isNaN(result)) {
result = 0.00;
}
return (result);
}
function Show_Total()
{
var TotalSum=0;
var Summ;
for(var i = 0; i < store_orders_itemsElements.length; i++){
Summ = StrToFloat(store_orders_itemsElements[store_orders_itemspriceID].value) *
StrToFloat(store_orders_itemsElements[store_orders_itemsquantityID].value);
TotalSum = TotalSum + Summ;
if (Summ == 0) {
store_orders_itemsElements[store_orders_itemsSumPriceID].value = "";
} else {
store_orders_itemsElements[store_orders_itemsSumPriceID].value = Math.round(Summ*100)/100;
}
}
document.store_orders_items.Total_price.value = Math.round(TotalSum*100)/100;
}
