I have a simple calculator written using javascript and html. I would like to make it such that when a link to the calculator is clicked, a pop up window with this calculator appears rather than referring a user to anew page.
View 2 RepliesI'm trying to make a calculator app; with a few differences. I have a text field with a numberpad below it, I got the numbers to show up in the text field, but am unsure as to how when I hit the enter button - it would store them in a variable?...I am also wondering as to how it would store current value and then allow me to input another value(maybe on the next page) and either subtract or add to it(the first value that is stored).I am also wondering how to get a decimal point in place(need it for currency).

I am trying to create a price calculator that automatically calculates the price of custom made picture frame. I got an equation that finds the square area of the frame by multiplying the perimeter (2*length*width) by the thickness (which the user can choose from 1.5", 2" or 3"). Then it multiplies it by a decimal number (0.27 if the frame is 1.5" thick, 0.23 if its 2" thick, and 0.18 if its 3" thick). Then it adds a $5 custom made fee to the final answer. But when I save it to an html file and load it in Internet Explorer, it doesn't calculate. Code:

Happy Calculating...
I'm attempting to create a shopping cart shipping calculator using the total $ provided by the cart itself (%total%). Basically the script needs to take the %total%, compare it to a bunch of arrays in the javascript, and provide the shipping charge as a percentage of the total. For example:
The cart total ends up being $15 (or %total%).
The set rates for shipping are:
Standard Shipping
$1 - $4.99 : 7.95% (of total)
$5 - $9.99 : 9.95%
$10 - $19.99 : 11.95%
Overnight Shipping
$1 - $4.99 : 9.95% (of total)
$5 - $9.99 : 11.95%
$10 - $19.99 : 19.95%
Two radio buttons would show the 2 shipping options and the shipping charges like this:
O Standard: $1.79
O Overnight: $2.99

I am trying to make a calculator that calculates the amount of words inputted (words) and multiplying it with a variable decided by an If/Then statement. The way I want it to work is that if there is 1-10,000 inputted it multiplies whatever that amount is by .29, and if there is 10,000-20,000 by .26, and anything more than 20,000 by .24.

I am trying to implement a time calculator onto my website with preset times to tell how long it would take to make troops. Say you want to make 100 Catapults and each Catapult takes one minute and ten seconds to make, I would like to be able to show the time in days /hours / minutes preferably in the format of 0:00:00. I would like it so someone can type in the amount of troops they want. There are Infantry that take 0:00:22, Cavalry that take 0:00:52, Archers that take 0:00:35 and Catapults that take 0:01:10.

Here's the deal...I have a form in my Coldfusion page that is a financial calculator (you type in the amount of the goods and the interest and it computes your monthly payments. It drops the numbers into the input fields in the form). This form uses javascript to do the calculations. So here is the problem.
I have three columns on my site. The left column has a couple of short forms that use the "CFFORM" tag. It seems that when i have the CFFORM tag in the page for whatever the reason the form can't do that math anymore. When I remove the CFFORM from the page it works fine.
What is the work around for this and why is there even a conflict between the two? I am closing all of my tags form tags.
I also use ColdFusion includes in the page, are they going to cause problems with the script too?
so i am working on a calculator but i am having trouble with the % buttonif i do 200*50% it should be 100, but now it says 0.5the function code:
