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);
f
Code:
unction up(){
var inpt= document.getElementById("item_one").value
document.getElementById("aCom_total").value=Math.floor(inpt)
}
function up2(){
var inpt= document.getElementById("aCom_total").value
[Code]....
I input the valve 100 in textone my total =100 I input the value into 20 text two my total is not 120, but 10020
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?
how to add up a series of text boxes which contain numbers that a user will input and have the total of those text boxes show up in a quantity text box on the next page.
Not sure if i should use javascript or php, but i don't know how to do it either
I want to select numbers from a list box and add it to a text box with comma separated. my java script code does not work into browser but work fine into eclipse jsp view.
function passingNumbersToTextArea(numToCall,allNum)
{
var numFromList=document.getElementById(allNum);
var numToTextArea=document.getElementById(numToCall);
if(numToTextArea.value.search(numFromList.value)!=-1)//if duplicate Number is exist
{
alert("Duplicate Number Can not be added :");
return false;
}
else
{
if(numToTextArea.value.length!=0)
{
// If textarea has value than it added another value with comma seperated
numToTextArea.value=numToTextArea.value+','+numFromList.value;
return false;
}
else
{
numToTextArea.value=numFromList.value;
return false;
}
}
}
jsp code
<h:inputTextarea cols="10" rows="4" id="numberToCall" required="true"
value="#{conferenceCall.numberToCall}" styleClass="form_input_box" />
<h:selectOneListbox styleClass="form_selectmenu" id="allNumbers" size="5" onclick="passingNumbersToTextArea('numberToCall','allNumbers');">

I have a database script that returns dates in the following format:
yyyy-mm-dd
I have been using the following code to change this format to dd-mm-yyyy:
<script type="text/javascript">
var myString = "[[date]]";
var mySplitResult = myString.split("-");document.write(mySplitResult[2] + "/" + mySplitResult[1] + "/" + mySplitResult[0] );
</script>
However, I now want to display the date in text format, e.g. 01-08-2009 would be displayed as 01 August 2009.how I change the script to show this format?

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.
View 4 Replies View RelatedI'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)....
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 = "";

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.
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.
I'm building a form that is calulated based on the options selected with a javascript form. This is my first attempt at something like this so I'm a bit lost at the final update.
First to be sure I'm on spot here is the javascript I'm using to update the form - <script>
function BDWcalc ()
{

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;
