Here's what I do...
function reCalcOrderForm() {
document.FormOOS.EDUSubtotal.value = 0
if (document.FormOOS.FoodPicturesQty.value != "") {
document.FormOOS.FoodPicturesSubtotal.value =
parseInt(document.FormOOS.FoodPicturesQty.value) * 15;
document.FormOOS.EDUSubtotal.value =
parseFloat(document.FormOOS.EDUSubtotal.value) +
parseFloat(document.FormOOS.FoodPicturesSubtotal.value);
}
if (document.FormOOS.EYOQty.value != "") {
document.FormOOS.EYOSubtotal.value =
parseInt(document.FormOOS.EYOQty.value) * 32.50;
document.FormOOS.EDUSubtotal.value =
parseFloat(document.FormOOS.EDUSubtotal.value) +
parseFloat(document.FormOOS.EYOSubtotal.value);
}
if (document.FormOOS.EYOTeacherQty.value != "") {
document.FormOOS.EYOTeacherSubtotal.value =
parseInt(document.FormOOS.EYOTeacherQty.value) * 13.25;
document.FormOOS.EDUSubtotal.value =
parseFloat(document.FormOOS.EDUSubtotal.value) +
parseFloat(document.FormOOS.EYOTeacherSubtotal.value);
}
if (document.FormOOS.EYOStudentQty.value != "") {
document.FormOOS.EYOStudentSubtotal.value =
parseInt(document.FormOOS.EYOStudentQty.value) * 20;
document.FormOOS.EDUSubtotal.value =
parseFloat(document.FormOOS.EDUSubtotal.value) +
parseFloat(document.FormOOS.EYOStudentSubtotal.value);
}
}
This basically multiplies the Quantity with a hard coded price, if the
Quantity is not blank. (There should probably be a NAN evaluation after
identifying that the field is not blank.) I re-do all this on the server
side anyway with stricter format checks (and especially ignoring the totals
generated by the Javascript - I only use the Quantities and re-capture the
prices from my service side price list), so the JavaScipt is just icing on
the cake.
