Non-repeat Random Number Generator?
Aug 14, 2011
I've looked everywhere for a random number generator which doesn't repeat. Tried loads and none have seemed to work.I'm making a quiz, 5 questions so far.This button, in html, generates the next random Q:But I need a random generator which fires them off only once. Anyone have suggestions for a non-repeating random number gen which will work? Even the one now seems to have some slight error associated with it. The one's ive tried so far haven't worked..

the script is supposed to allow the user to enter a minimum and maximum value and then enter the number of random numbers to generate between the min and max.
then it is supposed to floor these numbers and post the in a single column table. my script is writing the table correctly but the numbers arent coming through
Code:
<table border = "2">
<script type="text/javascript">
var min = window.prompt("Enter the 1st number","");

I have a piece of code that randomly picks a line from a preset list and displays it whenever the page is loaded. I'm using it to generate random quotes on my pages.
At the moment, there seems to be a good chance that when the page loads no quote appears at all, just a blank space.
Anyone know why this could be happening?code...

I have a problem with a random link generator within a DIV. When I try it on my desktop it works fine, but does nothing once I upload it to the website.how to explain what happens, but here is it, more or less:The website is this: http:[url]....
Via an Ajax script, http:[url]..... is loaded into DIV "menu". Here's the script:
<script type="text/javascript">
ajaxpage('menu.html', 'menu') //load "menu.html" into "menu" DIV
</script>
Well, there's another load of stuff inside the <head> tag. You may see it from the main page source code.Anyway, if you go to the menu.html, the link generator will work there as it is intended; however, if you try it from the main page, it won't do anything. But people are not suppossed to go to menu.html. They are suppossed to load it from the index.html (I mean, plain http:url....)So, here's the link generator code:
---------------------------------
<script type="text/javascript">
function randomlinks(){[code].....
I believe this could be solved if I could target the generator to the whole window, 'cause maybe it's trying to open the new page inside the DIV. Well, I don't know...

I haven't really used javascript before except for the odd snippet, and I was wondering if anyone can help me with a problem I have:
I need a script that chooses a phrase at random from 4 pre-defined lists of phrases, and does it all from the one page - rather than a separate page and a separate script for each pre-defined list of phrases.
I hope this is clear enough! Here is an example to illustrate what I mean:
This would be the text that appears on the webpage:
Click here for random Phrase Type 1
Click here for random Phrase Type 2
Click here for random Phrase Type 3
Click here for random Phrase Type 4
When clicking the first option, it only chooses from pre-defined list #1, the second option only chooses from pre-defined list #2, and so on.
It then displays the randomly generated phrase in one separate box, no matter what pre-defined list was chosen. (Although if each phrase has to be displayed in 4 separate boxes, that'd be ok too.)

I'm trying to make a Quiz that generates random pictures each time the page is launched , with multiple options for the user to choose the right answer satsifying the picture and its meaning .
I've made the pseducode and i understand the algorithm ..but i don't know how to write the statements .
My algorithm is :
1-Random picture is shown each time the page is launched.
2- 6 Buttons are placed .
3-user choses the right matching answer.
4- window is popped up saying "correct"when its correct if not , an alert saying ;'Your answer is incorrect. Please try again"
So this is the code i've made , i know there's errors but just to show the Idea.

I am taking a Javascript class and the teacher assigned this: Quote: Write a script that uses a random number generation to create sentences and name it sentences.html. Use five arrays of strings called: uppercase article (uarticle), noun, verb, lowercase article (larticle), and preposition. You will need to use the correct case for the article arrays. Create a sentence by selecting a word at random from each array in the following order: uarticle, noun, verb, preposition, larticle, noun. You can find examples of generating random numbers in both Fig. 8.6 (dice-rolling) and Fig. 8.7 (random image) of Chapter 8.
The arrays should be filled at minimum, as follows: the article array(s) should contain the articles: the, a, one, some and any. The noun array should contain the nouns: boy, girl, dog, town and car. The verb array should contain the verbs: drove, jumped, ran, walked, and skipped. The preposition array should contain the prepositions: to, from, over, under and on. If you would like to add more words, adjust the arrays appropriately.

My assignment is to create an online quiz with a random image generator. I have created my online quiz using 5 linking files and everything works great. My only problem is getting the images to show up on my quiz. All I get is the filename with a red X. Which the files do show up at random when I refresh, so I know that part is working. I just don't know what I am missing to get the actual picture to show up. Please keep in mind this isn't the whole code as I have different linking files for this assignment.

myQuiz.logo.src = pictures[rimg]+'.gif';
myQuiz.logo.alt = rimg + ' : ' +pictures[rimg];

I have used the below code, found on a forum from 2006, to generate a random image on my website with a link and accompanying text.The image works fine, the link that goes with each image is fine.Problem is: the text beneath the image does not match the image and link. This seems to be generated as a separate random element. Can anyone tell me how I can make my site display image 1 + link 1 + quotation 1?

actually i am working on a project "random password generator". What basically is to be done in this project is to generate user password for the username randomly he has provided. Then, this password is to be stored in a text file in the following manner
UserName Password
ABCD JU12H6
Sdjksj HJudfdsfd
Now my problem is that every time I just try to generate a new password, either a new file is made or the heading is rewritten again and again or if I just try to change the variables true and false, then the username and password headings are not printed. Please help. If someone knows how to do this using if-else method then please tell me, how it can be done? The code is attached.

I have to create a website as a project for my university course. Said course has nothing at all to do with computers really so it's really throwing us into the deep end as the majority of us have/had no interest in this particular field.
Regardless, I am creating a website that uses the Random Quote Generator Javascript that I copied from the Hotscripts website. The code details are below and my question is: is there any way I could change the formatting for each quote? For example, change quote 1 to be, say, yellow or bold and change quote 3 to be aligned right and blue? I mainly want to change the colour for each quote but having any other info on how to format it would be really helpful.
var quotes=new Array();
quotes[0] = "This is quote 1.";
quotes[1] = "This is quote 2.";
quotes[2] = "This is quote 3.";

this script lists the basic elements of a word and chooses a random word structure to make the word pronouncable... or... at least 50% of them ;). I'm sure there is a way to do this to cut down on the code... but here goes anyway...
<script>
/****************************************

* Random "Pronouncable" Password Script *

****************************************/
var letters = "bcdfghjklmnprstvwxyz";
var vowels = "aeiou";
groups = new Array();
groups[0]="th";
groups[1]="ch";
groups[2]="sh";
// groups[3]="qu";
function generate(number) {
// randomize letters
var vowel1 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group1 = groups[Math.floor(Math.random()*groups.length)];
var letter1 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel2 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group2 = groups[Math.floor(Math.random()*groups.length)];
var letter2 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel3 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group3 = groups[Math.floor(Math.random()*groups.length)];
var letter3 = letters.charAt(Math.floor(Math.random()*letters.length));
var vowel4 = vowels.charAt(Math.floor(Math.random()*vowels.length));
var group4 = groups[Math.floor(Math.random()*groups.length)];
var letter4 = letters.charAt(Math.floor(Math.random()*letters.length));
// specify the structure of the words (in order for them to be pronouncable)
// feel free to add your own...
structure = new Array();
structure[0]=letter1+vowel1+letter2+letter3+vowel2+letter4+vowel3+group1;
structure[1]=group1+vowel1+letter1+letter2+vowel2+letter3;
structure[2]=group1+vowel1+letter1+letter2+vowel2+group2;
structure[3]=group1+vowel1+letter1+vowel2+"s";
structure[4]=vowel1+group1+vowel2+letter1+vowel3;
structure[5]=group1+vowel1+letter1+vowel2+group2;
structure[6]=vowel1+group1+vowel2+letter1;
var password=structure[Math.floor(Math.random()*structure.length)];
if (number==1) {
document.passform.passbox.value=password+Math.floor(Math.random()*100)
}
else {
document.passform.passbox.value=password;
}

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 .

I'm trying to apply something in my forums, where a member could post something let's say:"Hi, I am number 1, 6"And what would happen is that, a number from 1 to 6 would be the content, for example, it would be:"Hi, I am number 3"But if you refresh the page, it would still be the same number. Like it won't be randomized again.So how do I make a javascript/html code that would make a one time number randomizer.

In the forum, it usually talked about generating a number between 1 or 0 to that certain value using something like Math.round(Math.random() * 200); or Math.floor(Math.random() * 200);
But what do you do if you want to generate a number between 201 and 400.
