JavaScript - Random Text?

Hi, I have been here before and was responded to quickly with professional results, and you guys have managed to bring me back!
Anyway, I am horrible at coding, and I need to know how to write this, basically when the page loads a random number is generated

<script type="text/javascript">
window.onload=function() {
var random = Math.rand() * (6 + 1);

Then later in the page

if (random = 1)
{
document.write("1")
//I'm not sure if thats the code to show simple text, but I'm pretty sure it is, correct me if I'm wrong
}
if (random = 2)
{
document.write("2")
}
if (random = 3)
{
document.write("3")
}
and so on so forth.

I will be changing the numbers in the script to my accord and use of the script, so please use the //notes to mark where and what things is, with a brief explanation, so I don't have to unscramble the code to find out what it is.
Thanks fellow nerds!

I've looked for a solution to this issue, but it seems like a little different scenario than other situations.

I made a system for generating friend requests on Facebook. I have a grid that is 6 x 3, for a total of 18 cells. Each cell has a picture in it, and the picture is linked to the Facebook friend request page. My problem is that since each cell is populated at random from the array, I'm getting lots of repeats. For example, some picutures are in 5 cells, and some are in none. I'm trying to figure out how to make it so that once a picture is used once in the grid, it does not get used again in the same grid. I still want every cell filled at random on each page load, I just want to prevent the repeating.

Here's my current code:
Code:

<script type="text/javascript">
var vip_list=new Array(

Hi - in editing a website...this javascript html is really getting on my nerves - can somebody please tell me why i keep getting the error message

expected ")"

when i try this code: (which ive fiddled around with bloody loads to try and resolve!)

<SCRIPT LANGUAGE=JAVASCRIPT >

var r_text = new Array ();
r_text[0] = Text 0;
r_text[1] = Text 1;
r_text[2] = Text 2;

var i = Math.floor(3*Math.random());

{
document.write("<marquee style="font-family: 'Georgia'; color: #FFFF00; font-size: 13pt; mso-fareast-font-family: 'Arial'" ><scrollamount="15"><b>" + r_text[i] + "</b></scrollamount></marquee>");
}


it seems fine to me and is getting me really frustrated now

any help greatly appreciated, do whatever you like to the coding if itll work!

thankyou very much, joe.

As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page.

For Example:

Input- 512

Output - Austin, TX

The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen. Thanks!

Hi,

I have a form with 9 text fields and a text area. What I want to do is replace the text in the text area depending on how many fields contain text. For example my text boxes are named 1 to 9, if the user enters text in the first five boxes I want the text area to auto fill with 'you have selected boxes 1 to 5' if the user selects all nine it will say 'you have selected 1 to 9', therefore, the user must complete the text boxes in order. I have it working with an onchange event but i have a button on the form to also auto fill the text boxes and it does not work if this is clicked.

Any help would be appreciated!

Hi all,

Thanks for reading. I'm having an issue trying to accomplish the following -

I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after.

This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly?

Code:

<script language="javascript">

fields = 1;

function addMore() {

if (fields = 1) {

document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";

fields = 2;

} else if (fields = 2) {

document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;

} else {

document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;

}

}

</script>

Here is the code in my HTML -

Code:

<input type="text" name="field1" size="25" /> <span>Field 1.</span>
<div id="addedMore"></div>
<p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p>

Thank you very much.

Hi,

I'm not much of a programmer, I have this script for randomly rotate a bunch of pictures.
What do you change to make to change from one another, not random?

Thanks
Denny

<script language="javascript">

var delay=5000 //set delay in miliseconds
var curindex=0
var i = 0
var randomimages=new Array()

randomimages[0]="...image01.jpg"
randomimages[1]="...image02.jpg"
randomimages[2]="...image03.jpg"
randomimages[3]="...image04.jpg"
randomimages[4]="...image05.jpg"
randomimages[5]="...image05.jpg"

var preload=new Array()

for (n=0;n<randomimages.length;n++)
{
preload[n]=new Image()
preload[n].src=randomimages[n]
}
i = Math.floor(Math.random()*(randomimages.length))
document.write('<img border=2 name="defaultimage" src="'+randomimages[i]+'">')
function rotateimage()
{
if (curindex==(tempindex=Math.floor(Math.random()*(randomimages.length))))
{
curindex=curindex==0? 1 : curindex-1
}
else
curindex=tempindex
document.images.defaultimage.src=randomimages[curindex]

}
setInterval("rotateimage()",delay)
</script>

I've started studying JavaScript recently. The following simple scenario from the Russian textbook cannot be implemented on my PC.
Code:

<HTML>
<HEAD>
<TITLE>Object Math Example</TITLE>

</HEAD>

<BODY>
<h1>Object Math Example</h1>
<p>Насколько случайны числа, полученные генератором случайных чисел? Подсчитаем среднее 5000 случайных чисел.</p>

<SCRIPT LANGUAGE="JavaScript">
total = 0;
for (i = 0; i<5000; i++)  {

        num = Math.random();
        total += num;
        document.status = "Generated " + i + " numbers";
      }

average = total / 5000;
average = Math.round(average * 1000 / 1000);
document.write("<h2>" arithmetic mean of random numbers  + average + "</h2>");

</SCRIPT>

</BODY>
</HTML>

I just typed the script char by char. I use Firefox browser, v.3.5.7. The error console does not display any mistakes.
Please, explain me what is wrong in the code.

I can generate a random number between 1 and 9,
( var rand_no = Math.floor( 1 + Math.random() * 9 ); )
but I want to add that random number to a value that is enterred into an inputbox and get a total.
How can I do this using Javascript and put the result into a hidden field.
I will also need to use that same random number in another place on another form .

Thanks

I recently decided to organize my bags on http://www.coach-bag.org/category-1-...+Handbags.html - I labelled all the boxes, making sure each box had only one purse in it's dustbag and organized by season. I have 14 at the moment - 4 for Spring/Summer and 10 for Fall/Winter. I actually (OK, this is going to sound oh-so-anal) did up a schedule by week and purse and will change over every Sunday morning. I did the schedule until the end of January and each purse only gets into rotation twice - that's not very much and I hate the idea of things not getting adequate usage. And it really got me thinking as to what else I really need - but then again, who needs 14 purses, right? We all know this isn't about need.

So that got me thinking about something mentioned in another thread. I have a price point in my head that I'm not comfortable going over per bag and it's $400. I had a brief moment when I considered the floral Sophia, but once I saw the modelling shots and figured out she was too big, I dismissed it and was a little relieved to do so.

But with 14 bags not getting into rotation that often, I'm wondering if I should change my mindset to buy 2-3 more expensive bags per year rather than what I did in this first 14 months of Coach collecting - which was buy 14 (plus all the wallets, scarves, keyfobs and other goodies). If I do that again this year, that means I could be close to 30 purses, and honestly, I'm not comfortable with that many bags - not from the financial standpoint - just the usage or lack thereof standpoint.

It seems like a lot of you ladies do spend the big bucks on bags - and lots of them - and that's great. I'm not independently wealthy, and I refuse to run a credit card balance for purses, so I only buy what I can afford and usually wait for PCE. And I guess I love a deal more than I love any individual purse, so it will really be a change in mind set for me to pay maybe $1000 for a bag maybe 2-3 times a year instead of what I've done this past 14 months where I bought 14 bags - mostly at 25%, 40% or outlet pricing.

I know for some of you ladies who have DOZENS of bags, my 14 must seem minuscule and you probably think I'm nuts for thinking so hard about it - but I need to find the right balance, and I guess I'm just trying to sort that out.

Does anyone else think so hard about this silly little topic or is it just me?

Thanks for letting me unload my thoughts here!!

Alright, I need a little help with my javascript. I'm a bit of a novice when it comes to programming so I apologize if this appears trivial.

I have an element ID that begins with bb + a randomized number between 1-100,000. This number changes after every action so what I need is a way to retrieve this new value each time and implement it into my code. I can view the number using firebug but I need a way to automate this process. Do any of you have some advice about how I could approach this problem?

I need to write something like this: http://justsheri.com/webscripting/wsassignment/1049950/

If you look at the code there is 52 of these <img src = './images/blank1.png'

Hi i have set up a token key to give me some extra protection against direct url access to the page but i wanted to make it random.

at first i used session token but it is not set until after a page refresh on login so this has to be its own deal..

i have found several javascript random codes but how to i pass that value to the window call..

here is the window call.. as you can see right know i have it hard coded as one token all the time. i just need it random and then sha1 (or md5)

Code:

function url_chat(){
chatwindow = window.open("<?=$CONST_MY_ROOT?>/mychat/chat/index.php?tok=0ed61bdd3a8a86f39e6b4abd01ba4e3649d0ec1c", "chatwindow", "location=0,status=0,scrollbars=0,menubar=0,resizable=0,width=950,height=550");
}

i could use this i guess but i dont know how to get that value to the window call above.

Code:

document.write(Math.floor(Math.random()*999999999999999999));

Hello!

I have an array of strings, like this:

var strings= [
"car", "black", "word", "small", "paper", "doom", "elemental",
"sword", "mouse" ];

Now i got a function newgame() and i wanna display random word from this array in rectangles gray styled...
Here is the problem. I can make to display random words, but i dont know how i make this words with the css style together - rectangels around a char. But the words are different length so i dunno?

When i press newgame button, i want for example to random a word from the array:
for example word "paper"
then i want it to be displayed like this [p] [a] [p] [e] [r], where [ ] are rectangels around the chars ( with the css style, like this:
border: 1px solid #000;
width:10px;
background-color:gray;
text-align:justify;
padding: 5px 10px;
i make a gray rectangle border around the char, but how can i make it work with random words?

How can i make it work? Any help please!
