JavaScript - Non-repeat Random Number Generator?
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: Code: <input type="button" value="Next (random)" name="B0" onClick="rangen();generatequestions();qnum()"><br><br> Lower down in the javascript (in the body), here is the rangen() function: Code: function rangen(){
whichone=Math.floor(Math.random()*5)
}
But I need a random generator which fires them off only once. For reference, here is the next bit (not so important): Code: var whichone=1;
var q=1;
var tempmn=document.instantquiz.thequestion
function generatequestions(){
if (q>0)
q=q++
if (loop>0)
loop=0
document.instantquiz.theresponse.selectedIndex=0
if (!document.instantquiz.cmode.checked||whichone>=total+1||whichone<=0)
document.instantquiz.thesolution.value=''
if (whichone>=total+1)
tempmn.value="End of quiz"
else{
tempmn.value=whichone+")"+question[whichone]+"\n\n"+"a)"+eval('choice'+whichone+'[1]')+"\n"+"b)"+eval('choice'+whichone+'[2]'
)+"\n"+"c)"+eval('choice'+whichone+'[3]')+"\n"+"d)"+eval('choice'+whichone+'[4]')
if (document.instantquiz.cmode.checked)
document.instantquiz.thesolution.value=solution[whichone]
}
}
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.. Similar TutorialsHi, I have a 'Register' page on my site. When someone registers to my website, I would like to make it necessary to have a div box which generates a random number/letter, which is linked to a text field where the user has to match the generated output. I've been sitting here wondering which would be the best route to take regarding completing this. I was thinking about using charAt() method. Could anybody please possibly give me some tips for generating random letter/numbers? Possibly would I create a string containing "ABCDE....Z0123456789", then use the charAt method to find a character at a certain index position? If so, would I need create something which generates a random index position? Any help would be fantastic, thank-you. Hey guys, I scripted a javascript guessing game and I am not sure how I can configure the random number generator to only generate one number and then stop. Here is my code: Code: <html>
<head>
<title>Guess it up! </title>
</head>
<body>
<center>
<BODY onLoad="GenerateNumber()">
<b><font size="5" ><u><b>Guess it up!<br></b></u>
<br >
<font size="3">
This is out of: <br>
<input id="DefaultNumber" name="DefaultNumber" type="text" size=3><br>
Type in your guess: <br>
<input id="HisGuess" name="HisGuess" type="text" size=3>
<p>
<input name="StartButton" type="button" value="Guess" onclick="StartGame()">
</p>
<script type="text/javascript">
function GenerateNumber()
{
var TheRightGuess = Math.round(Math.random() * (document.getElementById("DefaultNumber").value))+1; //Makes the randomly generated right guess. The "+1" makes it 1-5 instead of 0-4.
}
function StartGame()
{
var TheRightGuess = Math.round(Math.random() * (document.getElementById("DefaultNumber").value))+1; //Makes the randomly generated right guess. The "+1" makes it 1-5 instead of 0-4.
var HisGuess = parseInt(document.getElementById("HisGuess").value);//his guess
var DefaultNumber = parseInt(document.getElementById("DefaultNumber").value);//number that they want to guess in.
//NUMERIC TEST STARTS HERE
if (HisGuess != parseInt(HisGuess) || (DefaultNumber != parseInt(DefaultNumber)))
{
alert("Please enter numbers only.")
}
//NUMERIC TEST ENDS HERE
if (DefaultNumber <= 0) //Fixed bug:Guessing in zero.
{
alert("You can't guess in zero!?")
}
else
if (DefaultNumber === 1 && HisGuess === 1 || TheRightGuess == HisGuess && DefaultNumber != 1)//testing if they guessed in 1 and guessed 1.
{
alert("You got the number!")
}
else
if (HisGuess > DefaultNumber)//if guess is higher then what they guess in.
{
alert("You can only guess below " + DefaultNumber + ".")
}
else
if (HisGuess != TheRightGuess && HisGuess <= DefaultNumber && DefaultNumber != 1 || HisGuess == 0)//fixed bug: you can't guess 0.
{
alert("Guess again!")
}
}
</script>

Thanks, Fizz Hello all! I'm completely new here so I hope I'm doing this right and posting this in the appropriate subforums - if not, my apologies! Anyways, on to my actual problem. I am using the following script on a website to display a different image every time one visits/refreshes. The problem is, sometimes, instead of one of the images I have defined, it will come up with a broken image. I have tried to find something about this kind of thing in tutorials and such, but I have been unable to find anything on the subject. So - here's the code I'm using - Code: <script type="text/javascript">
<!--
var rand=Math.round(Math.random()*6);
var img=new Array(6);
img[0]="layout/bottomright/00.gif";
img[1]="layout/bottomright/01.gif";
img[2]="layout/bottomright/02.gif";
img[3]="layout/bottomright/03.gif";
img[4]="layout/bottomright/04.gif";
img[5]="layout/bottomright/05.gif";
document.write("<img src=\"" + img[rand] + "\" />");
//-->
</script>
Because I have extremely limited knowledge of JavaScript, I am not sure where the problem lies. (I made this script following a tutorial a long time ago and it worked completely fine then - I only changed the number in the "var rand" line to match the number of images I'm using this time, and the issue was present right from the start. I changed "var img" a lot in attempts to fix the issue - like I said, little knowledge, so I was just trying things - but it made no difference.) A more savvy friend of mine pointed out that the generator throws an "undefined" number occasionally, but she didn't know why. So... any help? I hope it's not too complex an issue. Thanks in advance! Hey guys. It's been a while since I was last here but I'm having a few problems. I'm building a random word generator form for a friend but my knowledge of JS is limited. I have found a script to randomly generate a word at the click of a button.

Foster Hi, 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 take a look at my code below and see if I am missing anything. Please keep in mind this isn't the whole code as I have different linking files for this assignment. Thank you in advance. Code: <?xml version = "1.0" encoding = "utf-8"?>

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? the code I am using is: Code: <script type="text/javascript">
q0= "<img src=\"images/quotes/01.png\" />";
q1= "<img src=\"images/quotes/02.png\" />";
q2= "<img src=\"images/quotes/03.png\" />";
q3= "<img src=\"images/quotes/04.png\" />";
q4= "<img src=\"images/quotes/05.png\" />";
q5= "<img src=\"images/quotes/06.png\" />";
q6= "<img src=\"images/quotes/07.png\" />";
q7= "<img src=\"images/quotes/08.png\" />";
q8= "<img src=\"images/quotes/09.png\" />";

Hi. 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. I'm not sure how to explain what happens, but here is it, more or less: The website is this: http://torcacita.atspace.com Via an Ajax script, http://torcacita.atspace.com/menu.html 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://torcacita.atspace.com) So, here's the link generator code: --------------------------------- <script type="text/javascript"> function randomlinks(){ var myrandom=Math.round(Math.random()*9) var links=new Array() links[0]="http://www.javascriptkit.com" links[1]="http://www.dynamicdrive.com" links[2]="http://www.cssdrive.com" links[3]="http://www.codingforums.com" links[4]="http://www.news.com" links[5]="http://www.gamespot.com" links[6]="http://www.msnbc.com" links[7]="http://www.cnn.com" links[8]="http://news.bbc.co.uk" links[9]="http://www.news.com.au" window.location=links[myrandom] } </script> <form> <input type="button" value="Lo Que Sea" onClick="randomlinks()"> </form> --------------------------------- 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... So, what do you think? Could somebody help me? Hi there... 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. Code: <html>

Hey I'm somewhat new to the javascript world because 95% of my website is HTML so, if you will, I need help writing the javascript for a Random Question Generator...basicly all I have is Code: <script type="text/javascript"> var Q = new Array() Q[1] = "What is your favorite color?"; Q[2] = "What is your favorite animal?"; Q[3] = "What is your favorite place?"; </script> In the real one, there will be about 20 questions and I will need it to choose a quetion randomly out of the 20. As I said i am a beginer so as simple as possible would be great. Thank You for your help in advance Question about random link generator http://www.javascriptkit.com/script/cut1.shtml I want to use this script to hold a hundred odd links and show 8 random urls at a time in a list separated by a couple of line breaks. (Instead of just one). Could someone pls alter the code to allow me to do this please ... I also hope to keep the js file off the main html page. (naming the file list.js) Could someone also indicate how I do this. Hopefully these questions are easy if you know how etc. So far i havent been able to do it... Would be good if i could add a line to prevent duplicate randomly drawn links appearing in the list of eight.... thanks very much if you able to indicate it..... Trying to develop a small app for my site. What is the code to generate a random # of lines (1 min - 5 max) and a random phrase for each line sourced from a multidimensional array? These also need to be unduplicated (so I won't have quote 1 be on lines 1 and 4). How do I prevent random duplication with the generated lines of text? Thanks!
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. As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the final sentence is output, it should start with a capital letter and end with a period. The program should generate 20 sentences and output them to the screen (document.write or document.writeln). You should use a for loop similarly to the one used in Fig. 8.6 in order to get it to print 20 times. I haven't gotten to the loop yet, I'm just working on the random sentence first. Here is what I have: Code: <script type="text/javascript">
<!--
uarticle = new Array("The", "A", "One", "Some", "Any");
noun = new Array("boy", "girl", "dog", "town", "car");
verb = new Array("drove", "jumped", "ran", "walked", "skipped");
larticle = new Array("the", "a", "one", "some", "any");
preposition = new Array("to", "from", "over", "under", "on");
var rand1 = [Math.floor ( Math.random() * uarticle.length )];
var rand2 = [Math.floor ( Math.random() * noun.length )];
var rand3 = [Math.floor ( Math.random() * verb.length )];
var rand4 = [Math.floor ( Math.random() * larticle.length )];
var rand5 = [Math.floor ( Math.random() * preposition.length )];
document.write(uarticle[rand2] + " " + noun[rand2] + " " + verb[rand3] + " " + preposition[rand1] + " " + larticle[rand4] + " " + noun[rand2] + ".");
-->
</script>
Am I on the right track? How would I loop the sentences using a for statement? Hi could someone please help?... I am a total beginner to javascript... but does anyone know of a code, including links to an image folder, for displaying 6 fullscreen images in random order without repeat for a given user? I've seen specific examples using shuffle on the site, but could anyone write a general code for any given images? Many thanks in advance 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. Code: var quotes=new Array();
quotes[0] = "This is quote 1.";
quotes[1] = "This is quote 2.";
quotes[2] = "This is quote 3.";
var q = quotes.length;
var whichquote=Math.round(Math.random()*(q-1));
function showquote(){document.write(quotes[whichquote]);}
showquote();
Also if you could put it into total idiot-speak for me I'd be oh so grateful. My array contains 15 value I want to random pick 5 value: Code: myArray[0] ="a"; myArray[1] ="b"; myArray[2] ="c"; myArray[3] ="d"; myArray[4] ="e"; myArray[5] ="f"; myArray[6] ="g"; myArray[7] ="h"; myArray[8] ="i"; myArray[9] ="j"; myArray[10] ="k"; myArray[11] ="l"; myArray[12] ="a"; myArray[13] ="b"; myArray[14] ="c"; How to random pick from all elements with no repeat of the same content. e.g. if myArray[0] is picked then myArray[12] will not be picked again. (because they have the same value "a") 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 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' onClick='clickCard("qh",0)'/> where clickcard("numchanges", increments by 1) how is this done? Thanks Danny This is quite easy yet hard. I'm trying to apply something in my forums, where a member could post something let's say: "Hi, I am number [random]1, 6[/random]" 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. i have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads. i posted this problem a while back, and the answers were great, but they coded the xhtml inside the html file. i'm trying to get the numbers to generate in the table that is formed in the javascript file using innerhtml. i tried to incorporate the solutions without putting the html inside the html file to no avail. var random = Math.floor(Math.random()*40 + 1) //sets variables for random numbers to generate var random2 = Math.floor(Math.random()*40 + 1) var random3 = Math.floor(Math.random()*40 + 1) var random4 = Math.floor(Math.random()*40 + 1) var random5 = Math.floor(Math.random()*40 + 1) var random6 = Math.floor(Math.random()*40 + 1) //create table function makeTable(lotto) document.getElementById("tableSpan").innerHTML = '<table border="1" id="lotto">'; var caption=document.getElementById('lotto').createCaption(); caption.innerHTML="JavaScript Random Numbers"; var x=document.getElementById('lotto').insertRow(0); var cell1=x.insertCell(0); var cell2=x.insertCell(1); var cell3=x.insertCell(2); var cell4=x.insertCell(3); var cell5=x.insertCell(4); var cell6=x.insertCell(5); cell1.innerHTML='<td class = "normal">'+ random +'</td>'; cell2.innerHTML='<td class = "normal">'+ random2 +'</td>'; cell3.innerHTML='<td class = "normal">'+ random3 +'</td>'; cell4.innerHTML='<td class = "normal">'+ random4 +'</td>'; cell5.innerHTML='<td class = "normal">'+ random5 +'</td>'; cell6.innerHTML='<td class = "red">'+ random6 +'</td>'; } heres the HTML file: <body onload="makeTable('lotto');"> <div id="container"> <div id="header"> <h1>Welcome</h1> </div> <div id="content"> <span id="tableSpan"></span> <input type="button" value="Re-generate Numbers" onclick="makeTable('lotto');" /> </div> { How would I generate a random number between 0 and 470 at multiples of 10 including 0 and 470?
