Correct Text For Displaying Remainder	View Content

Good evening. I'm very new to this, but very excited that I've gotten this code so close. I am trying to get the computer to determine if a number is even or not. This is what I have:

[CODE]
<script type = "text/javascript">
<!--
var firstNumber; // first string entered by user
var answer; // the division problem

// read in first number from user as a string
firstNumber = window.prompt("Enter an integer");

//how to get a remainder
var answer = firstNumber / 2

if (answer > 1)
{
document.writeln(answer + ". This number is even.");
}

</script>

The bottom part is the problem. I am able to code that if the answer is greater than one, then return the following text, however, I can't for the life of me figure how to say... if the remainder is zero.

Thank you,

How To Calculate A Remainder For A Division Sum

Hi there. I have a program that generates a random exam with digits 0 -9.

I have managed to generate random symbols to appear inbetween each question and it now accepts an answer. What i need is that when a division sum is generated, i need another field beside the answer for the remainder.

Here is the code:

Displaying Text In Text Box With Previous And Next Buttons

Similar Tutorials

Hi again

For instance I want to display some announcements from an external text file on a predefined box, like lets say 140 wide and height scalable according to text. The texts would be some announcements from me, a few words. I want the text justified and with previous / next link, if possible. And when they navigate to another page, they will get a random message in that box.

There are news tickers on the net, but I just want something simple like this, no scrolling, fading, etc..

Has anyone a clue how I can accomplish that? Thanks.

Please use code tags and put your code in them. It makes it easier on every one.

Your input button calls the function allThatStuff().
Code:

<input type="button" id="button" name="button" onClick="allThatStuff()" value="Determine the Author!">

But you do not have a function by that name. You only have a single function named Code:

 form.input4.onclick = function(){.....}

But even getting that straight wont work when you have things like:
Code:

if input4 = (inputAverage2 + i){
	var Author2="yes"
	var Author2Off = i
}

the if statement S/B Code:

if  ( input4  ==  (inputAverage2 + i) ) {....}

Displaying Text In Textarea Object

Similar Tutorials

hi all,
I have a simple website with 2 Frames,
In top frame I have a button that invokes CGI script and internally that CGI script prints info (text) into the bottom frame.
Going further we want to print the output coming from CGI into a textarea object in bottom form.

I have a function in my CGI script:
But ends up printing multiple textarea objects in lower frame.
We want to print each line of text into the same textarea object in lower frame. and at the end display a new button.
How can we do this using javascript/CGI?
I tried the following but not displaying anything.

sub print_message {
my($message1, $message2) = @_;
my $final_message = $message1 . " " . $message2;
print <<END_HTML;
<html>
<head>
<form name="myform">
<table border="0" cellspacing="0" cellpadding="5">
<tr>
<td><textarea name="outputtext" rows="10" cols="100">
$final_message
</textarea>
</td>
</tr>
</table>
</form>

<style>

</style>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<a href="main.html" rel="nofollow" target="bottom"></a>
<title>CTS Debug Information</title>
<style type="text/css"> img {border: none;} </style>
</head>
<body>
</body>
</html>
END_HTML

I created this function in javascript:

<script language="javascript" type="text/javascript">

function addtext() {
var newtext = document.myform.outputtext.value;
var nextLineTextNode = document.createTextNode(newtext + "\r\n");
var logData = document.getElementById("outputtext");
logData.appendChild(nextLineTextNode);
logData.scrollTop = logData.scrollHeight - logData.clientHeight;
}

</script>

But when i implemented in my CGI nothing is printed.

Thanks!!!

Need Help With Displaying And Editing Text Area

Similar Tutorials

I have a need to display, edit and save the contents of a text area to a text file or what ever is best suited, directly to the website root or folder within the root of the site. Is there anyway this can be done with out database software? As I dont have the option to install mysql or any other software to the webserver. Any help would be greatly appreciated. Thx

Just a little backround: The webserver is acually an open source linux firewall which i was able to edit the apache config file to host a second site. I just want the ability to store edit and display some network information within a very small site I made without the use of a database. Is this even possible?

Displaying Random Text Without Repeating The Content

Similar Tutorials

I'm using the script below in a custom HTML to generate a random line of text (not with the text shown here). This works fine BUT; I want it to go randomly through the WHOLE list without repeating lines that already have been printed. As it is now, a line of text might be printed several times in a row, which is a little annoying. I'm using a refresh button for generating a new line of text.

Alternatively, How can I just make it display in the order shown and just re-arrange the content so it seems random to the user? Random would the best though...

Any ideas?? : )

Code:

Correct Selector?

Similar Tutorials

Can anyone tell me what I have done wrong here? I have the following html code

Code:

<div id='group1'>
  <tr class='time'>
    <td colspan='3' name='1262815200'></td>
  </tr>
					
  <tr>
    <td class='timeleft group1' name='1262815200' colspan='3'></td>
  </tr>	

  <tr class='game'>
    <td><input type='radio' name='G1' value='NYJ'>NYJ</td>
    <td><input type='radio' name='G1' value='BUF'>BUF</td>
    <td><select name='G1P' class='points' tabindex = '1'></select></td>
  </tr>	

</div>

and when I use the selector $('#group1 input) it does not select anything (namely the inputs in this code). But when I use the selector $('div input') it will select them (and more on the page which I don't want). Is anyone able to see what I have done wrong? I've tried everything I can think of in terms of testing, and I have narrowed it down to the selector. Thanks.

Am I Using False The Correct Way?

Similar Tutorials

Does anyone know why I am not getting an alert on an empty form INPUT value?

Code:

if (document.forms["form"]["targetname"].value == "" && document.forms["form"]["unknownname"] == false) {
	alert ("What ever");
	return false;
}

document.forms["form"]["targetname"] is a form INPUT text
document.forms["form"]["unknownname"] is a form INPUT checkbox

I suspect the problem is due to 'false'.. but I can't figure out why.

Help Correct Textarea Javascript

Similar Tutorials

I found and am using the following script to add checkbox values to a textarea.

Code:

<script type="text/javascript">
function add_sub(el){
if (el.checked)
el.form.elements['type'].value+=el.value;
else{
var re=new RegExp('(.*)'+el.value+'(.*)$');
el.form.elements['type'].value=el.form.elements['type'].value.replace(re,'$1$2');
}
}
</script>
</head>
<body>

<form name="form1" method=post>
<textarea name="type" rows="5" cols="35" onclick="this.focus();this.select();">
</textarea><br>
<input type="checkbox" name="bob" id="bob" value="<p>" onclick="add_sub(this);"><label for="bob">&lt;p&gt;</label><br>
<input type="checkbox" name="bob1" id="bob1" value="<span>" onclick="add_sub(this);"><label for="bob1">&lt;span&gt;</label><br>
<input type="checkbox" name="bob2" id="bob2" value="<div>" onclick="add_sub(this);"><label for="bob2">&lt;div&gt;</label>

That is working. However, I wanted to put carriage returns after each checkbox value added, so I added the + "\r\n" as follows:

Code:

<script type="text/javascript">
function add_sub(el){
if (el.checked)
el.form.elements['type'].value+=el.value + "\r\n";
else{
var re=new RegExp('(.*)'+el.value+'(.*)$');
el.form.elements['type'].value=el.form.elements['type'].value.replace(re,'$1$2');
}
}
</script>

That is working when adding the value, but removing the value when the checkbox is unchecked is not working. I know the regular expression, etc. needs to be updated to account for the carriage returns, but I have tried everything I can think of and cannot get it to work.

Help correcting the code is appreciated.

Correct Rounding Procedure

Similar Tutorials

I have tried many ways to do this and have also searched the forum, no go. I was doing it manually doing this:

Code:

Math.round((#)*100)/100

But no go, so I found this function here on the forum:

Code:

function roundNumber(num, dec) {
	var result = Math.round(num*Math.pow(10,dec))/Math.pow(10,dec);
	return result;
}

No go, it works yes, don't get me wrong. But I am working on a invoicing system and it needs to be exact. For instance with this number:

Quote:
0.27470000001
It returns 0.27, when in reality it should return 0.28 because of the 7 changes the 4 to 5 and then 5 changes the 7 to 8. But it doesn't work.

While reading some things I found while searching google I see that Math.round doesn't work 100% the way it should mathematically.

So what options do I have left, I can't believe that a simple rounding calculationg that excel can do ha ha JS cannot.

Why Is My Javascript Homework Correct?

Similar Tutorials

Hello coding forum users,
I am working on the only javascript chapter of my HTML textbook.
It asks me to: Quote:
replace the line <img id="sky" src="sky0.jpg" alt=""/>
with a script element that writes the following HTML code:
<img id='sky' src='mapNum.jpg' alt=' ' />
where mapNum is the value of the mapNum variable.
so I try PHP Code:
<script type="text/javascript" />
document.write("<img id='sky' src='mapNum.jpg' alt=' ' />")
</script>

after a few other attempts I search codingforums and find: PHP Code:
document.write("<img id=\"sky\" src='sky"+mapNum+".jpg' alt='' />");

and PHP Code:
document.write('<img id="sky" src="sky'+mapNum+'.jpg" alt="" />');

and these work perfectly fine but I don't understand why? my textbook only has one javascript chapter and its really small and vague, and
my teacher hasn't answered my emails, so I would be grateful if anyone can tell my why my first code falls flat.

Return Message If First Value Is Correct?

Similar Tutorials

Hi, I'm trying to figure out how to make this work and I'm stumped.

I wrote this code:

<script type=text/javascript>
function firstfunction();
{
if(document.form1.inputnumbers.value="55");
{
document.form1.outputstate.value="this is a number";
}
else if
{
document.form1.inputnumbers.value="never";
}
{
document.form1.outputstate.value="this is a number";
}
else
{
document.form1.outputstate.value="";
}
</script>

<form name="form1" method="post">
<input type="text" id="inputnumbers" name="inputnumbers";>
<input type="button"; value="Enter"; onclick="firstfunction()"><br><br>
<textarea id="outputstate"; name="outputstate"; cols=60; rows=10; style="border:1"; readonly;>

I'm trying to doing something really simple but I can't seem to make it work. I'm trying have the textarea display a certain message depending on if the first input box says a certain word or number. So like in the code, if the user types "55" or "never" in the first box, then the second box should say a certain message. Then I used the else statement so that if "55" or "never" is not entered, then the second box says nothing.

If you can spot my error or suggest a different way of going about writing the code, it would be very much appreciated. Thank you.
