Hi
I have the following coding in my website that add's or remove's prices to a quote page and works perfect but I need to insert another input field that takes the order total and divides it by 2
Just wondering how I do that in this coding
Below is the HTML
<form name="checkbox">
One Page<input type="checkbox" name="PROD_CH_70.00" value="70" onchange="CalculateTotal(this.form)">
<br>
Two Pages<input type="checkbox" name="PROD_CH_140.00" value="140" onchange="CalculateTotal(this.form)">
<br>
Three Pages(Bronze Package)<input type="checkbox" name="PROD_CH_179.00" value="179" onchange="CalculateTotal(this.form)">
<br>
Six Pages(Silver Package)<input type="checkbox" name="PROD_CH_339.00" value="339" onchange="CalculateTotal(this.form)">
<br>
Ten Pages(Gold Package)<input type="checkbox" name="PROD_CH_549.00" value="549" onchange="CalculateTotal(this.form)">
<br>
New Business Start up<input type="checkbox" name="PROD_CH_289.00" value="289" onchange="CalculateTotal(this.form)">
<br>
Ecommerce Package<input type="checkbox" name="PROD_CH_449.00" value="449" onchange="CalculateTotal(this.form)">
<br>
SEO on all pages<input type="checkbox" name="PROD_CH_30.00" value="449" onchange="CalculateTotal(this.form)">
<br>
Logo Design<input type="checkbox" name="PROD_CH_25.00" value="25" onchange="CalculateTotal(this.form)">
<!--<input type="text" name="PROD_DC_15" size="10" maxlength="3" onchange="CalculateTotal(this.form)">
<input type="text" name="PROD_CC_20" size="10" maxlength="3" onchange="CalculateTotal(this.form)">-->
<br><br>
<span style="color: #FFFFFF;">£<input type="text" name="TOTAL" size="10" onfocus="this.form.elements[0].focus()
">
</span>
</form>
Below is the Javascript coding
function CalculateTotal(frm) {
var order_total = 0
// Run through all the form fields
for (var i=0; i < frm.elements.length; ++i) {
// Get the current field
form_field = frm.elements[i]
// Get the field's name
form_name = form_field.name
// Is it a "product" field?
if (form_name.substring(0,4) == "PROD") {
// If so, extract the price from the name
item_price = parseFloat(form_name.substring(form_name.lastIndexOf("_") + 1))
// Get the quantity
if(form_field.type == 'checkbox') {
item_quantity = form_field.checked;
} else {
item_quantity = parseInt(form_field.value);
}
// Update the order total
if (item_quantity >= 0) {
order_total += item_quantity * item_price
}
}
}
// Display the total rounded to two decimal places
frm.TOTAL.value = round_decimals(order_total, 2)
}
function round_decimals(original_number, decimals) {
var result1 = original_number * Math.pow(10, decimals)
var result2 = Math.round(result1)
var result3 = result2 / Math.pow(10, decimals)
return pad_with_zeros(result3, decimals)
}
function pad_with_zeros(rounded_value, decimal_places) {
// Convert the number to a string
var value_string = rounded_value.toString()
// Locate the decimal point
var decimal_location = value_string.indexOf(".")
// Is there a decimal point?
if (decimal_location == -1) {
// If no, then all decimal places will be padded with 0s
decimal_part_length = 0
// If decimal_places is greater than zero, tack on a decimal point
value_string += decimal_places > 0 ? "." : ""
}
else {
// If yes, then only the extra decimal places will be padded with 0s
decimal_part_length = value_string.length - decimal_location - 1
}
// Calculate the number of decimal places that need to be padded with 0s
var pad_total = decimal_places - decimal_part_length
if (pad_total > 0) {
// Pad the string with 0s
for (var counter = 1; counter <= pad_total; counter++)
value_string += "0"
}
return value_string
}
