[RESOLVED] Passing chargetotal value

I need to take a value generated by a javascript and pass it through a hidden input in an html form.

My LinkPoint merchant states that I need to use the following to pass the total:

<input type=”hidden” name=”chargetotal” value=””>

I need to have the value generated by the script inserted into the value tag so that information can be passed on. Below is the Form and script I would like to use. I would like to stick with the chargetotal value because it’s my linkpoint merhcant example – not sure what to do.

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
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)
frm.CHARGETOTAL.value = frm.TOTAL.value
}

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
}

This is by far the most mind boggling thing my head has endured thus far. Detailed help is much appreciated as my knowledge of j-script is weak.

Also in #PHP _↴
