# Numbers From A Text Box For Calculation

Mar 7, 2006

I have the two text boxes on a form, both of which a user enters a
number. I simple need to ADD THESE UP!

I know, its daft, but no matter what I do, it just adds them together.

Example: 1+1 is clearly 2, but it outputs 11!

An example of my code:

var loan = document.loandata.loan.value;
var other = document.loandata.other.value;

total = (loan+other);

## Real Text Size Calculation?

Jul 20, 2005

I've got a small problem here. I'm trying to write some code that would
generate a drop-down menue for me, where I'd just need to enter the
menu- and submenu items into an array. The items are to be displayed as
text. Now, I want to have the layers with the submenues to appear more
or less under the appropriate main menu items. For this I need to be
able to calculate how many pixels a given text uses up on the screen of
the user. That's all fine with IE and an unproportional font like
courier. The problem is, there is this nice setting that allows you to
change the diplay size of the text - which is pretty much disfunctional
in IE, but in mozilla, it works. Which means that I can't just say that
one letter in courier, size 2, is 4 pixels wide and be happy with my
calculation, because then somebody can just pop up with another text
diplay size and *boom* - my calculation is wrong again.

Now, is there a realistic way to find out how many pixels _exactly_ a
piece of text takes up on the user's screen? Or can I make the given
piece of text a DIV and then have some kind of document.divname.left
that gives me the actual location of this text?

## Update Text As Numbers Are Typed Into Input Field

Jul 22, 2010

I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

## Problem With Multiple Text Boxes Using Formated Numbers

Aug 13, 2007

I'm primarily a database programmer (Mysql and PHP) but I have some Javascript programming and I have been programming in other languages for over 25 years.

On to my problem:

I'm trying the create a function in Javascript which will take a variable from three different text boxes and show the net result in a fourth text box that is ReadOnly. This is all on the same page. All three text boxes have other Javascript scripts formatting the value in the text boxes.

Real example (simplified)....

## Include Numbers And Alphabets Instead Of Numbers Only?

Apr 7, 2009

I need to modify the script showed at: [URL]

Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.

And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?

The code at the above URL is as follows:

<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";

## Future Date Calculation

Jan 7, 2007

I am trying to make a script that prints a date in the format Sunday
14th January 2007. Where the date that is displayed is the next sunday
3 weeks from now. For example today is 7th January. The script would
print Sunday 28th January 2007. It would read that all of this week
until next sunday when it would change to Sunday 4th February.

## Problem With Time Calculation

Feb 5, 2007

It's probably something with rounding off, or floating point problems.
I have a timer which is used when solving the Rubik's cube. It has to
measure an exact time, but the clock display I made shows a different
value than the actual time (also displayed after session: ...). I am
using the same variable for both displays. sometimes it's off by .02.

## Checking The Date Calculation?

Sep 22, 2011

I have a javascript that should convert any date into a number between 1 and 260. Based on the outcome of that calculation, a viewer is directed to a specific web page.How can I verify the calculation? How can I see what number javascript is arriving at so I can backtrack to the error? It is not serving up the correct page.

I have compared the results to a calculator on another website [URL] that uses a different script to calculate the same result -- that's why I am saying the end results are not correct. On the other website, scroll down to where you enter a date. It returns a name just above the date (example: July 25, 1970 returns Electric Star). The script I included above returns Yellow Sun. July 25, 1970 should = 68.

function calculate() {
if(!isValidDate())
return;

## Javascript Calculation Onload

May 14, 2007

I currently have a web page that is building a web form from data contained in a SQL table. I need to do some calculations on the numbers that are populated into the form. I have used the following javascript code to successfully complete my calculations but I can only use this code at the bottom of my page because executing it at the top of my page the form fields are still empty. How would I use or modify the code I have to display the calc at the top of the web form. Example as follows:

<form method="POST" target="_self" name="dialer" enctype="text/plain">

Loan Amount: <input type="text" value="400000" name="loan" />
Interest Rate: <input type="text" value="1.00" name="apr" />
Amortization Term: <input type="text" value="480" name="term" />

</form>

<script language="JavaScript">

var princ = document.dialer.loan.value;
var term = document.dialer.term.value;
var intr = document.dialer.apr.value / 1200;

var output = princ * intr / (1 - (Math.pow(1/(1 + intr), term)));
var calc = (Math.round(output * 100)/100);

</script>

## Problem With Date Calculation In Form

Jul 20, 2005

I have a form which must calc the difference between 2 date fields and
return the result in a third field. I have the following code but it does
not seem to work. Can anyone tell this total newbie where he is going wrong
or suggest a more elegant way of doing this.

<head><script>
function doit(oForm, usrInp)
{
var one_day = 1000 * 60 * 60 * 24 ;

var userDate = new Date(usrInp)
var dueDate = new Date(usrInp)

diff = dueDate - userDate
oForm.diff.value = (diff/one_day) + ' days'
}

//-->
</script>
</head>
<body>
<form name="a">
<input type="text" name="userDate" >
<input type="text" name="dueDate" onblur='doit(this.form, this.value)'>
<input type="text" name="diff" onfocus=this.blur();>
</form>
