JavaScript - Display Divs Random
Hello,
i got a problem with my following js-script. Sorry I'm a noob. I want to display several divs with math.random. 12 divs are in an array, after this I place 6 of them randomly in another array and want to display them. But it doesnt happen and I dont know why . Here is my script: Code: <html>
<head>
<style type="text/css">
.hidden{display:none;}
</style>
<script type="text/javascript">
window.onload = function () {
var domelem = document.getElementById("wrap").getElementsByTagName("div");
var studis = [];
for(var i =0; i < domelem.length; i++)
{
studis[i] = domelem[i];
}
var a = [];
while(a.length <= 5)
{
var spliced = studis.splice(Math.floor(Math.random()*studis.length), 1);
a.push(spliced);
}
for (var i = 0; i < a.length; i++){
a[i].style.display = 'block';
}
}
</script>
</head>
<body>
<div id="wrap">
<div class="hidden">content</div>
<div class="hidden">content</div>
<div class="hidden">content</div>
<div class="hidden">content</div>
<div class="hidden">content</div>
........
</div>
The Problem is, that the divs are not displayed. I thought it was correct to do it like this. Please can anybody help, I dont know what to do. I would be very grateful. Similar TutorialsHi! I'm trying display ready made flashcards by using the example below. Now this works just fine. But I want the cards to be randomly chosen and displayed one at a time. Any ideas? I've been sitting up all night trying to figure this out on my own, but come to the conclusion that I need help, and sleep.. Code:
<head>
<script type="text/javascript">
window.onload= function() {
var divs= document.getElementsByTagName('div');
for (var i= divs.length; i-->0;)
if (divs[i].className==='question')
Toggler(divs[i]);
};
function Toggler(div) {
var state= false;
var toggled= div.nextSibling;
while (toggled.nodeType!==1)
toggled= toggled.nextSibling;
div.onclick= function() {
state= !state;
toggled.style.display= state? 'block' : 'none';
};
};
</script>
<style>
div.flashcard {
margin: 0 10px 10px 0;
}
div.flashcard div.question {
background-color:#ddd;
width: 400px;
padding: 5px;
cursor: hand;
cursor: pointer;
}
div.flashcard div.answer {
background-color:#eee;
width: 400px;
padding: 5px;
display: none;
}
</style>
</head>
<body>
<div id="1" class="flashcard">
<div class="question">Question goes here</div>
<div class="answer">Answer goes here</div>
</div>
</body>
</html>
tag! I've tried the solution below, which successfully generates random cards, BUT the toggling just works on the first flashcard in the code Code: <div id="randomdiv1" style="display:none;">
/*inserted this as content*/
<div id="1" class="flashcard">
<div class="question">Question goes here</div>
<div class="answer">Answer goes here</div>
</div>
</div>
<div id="randomdiv2" style="display:none;">
[content for div 2]
</div>
<div id="randomdiv3" style="display:none;">
[content for div 3]
</div>
<script type="text/javascript" language="JavaScript"><!--
NumberOfDivsToRandomDisplay = 3;
var CookieName = 'DivRamdomValueCookie';
function DisplayRandomDiv() {
var r = Math.ceil(Math.random() * NumberOfDivsToRandomDisplay);
if(NumberOfDivsToRandomDisplay > 1) {
var ck = 0;
var cookiebegin = document.cookie.indexOf(CookieName + "=");
if(cookiebegin > -1) {
cookiebegin += 1 + CookieName.length;
cookieend = document.cookie.indexOf(";",cookiebegin);
if(cookieend < cookiebegin) { cookieend = document.cookie.length; }
ck = parseInt(document.cookie.substring(cookiebegin,cookieend));
}
while(r == ck) { r = Math.ceil(Math.random() * NumberOfDivsToRandomDisplay); }
document.cookie = CookieName + "=" + r;
}
for( var i=1; i<=NumberOfDivsToRandomDisplay; i++) {
document.getElementById("randomdiv"+i).style.display="none";
}
document.getElementById("randomdiv"+r).style.display="block";
}
DisplayRandomDiv();

I'm in an experimenting phase doing a lot of copy/paste so if this is very far out I wiill very much appreciate alternatives. Thanks!! Hello, I have an array containing 100 different values. How would I randomly pick 25 of them for display? For now I do: PHP Code: for (var i=0; i<markers.length && i<25; i++) { html += markers[i].name + '<br />'; } Which of course returns 25 values but always in the same order which is not what I want. Thanks in advance! PS. My array could also contain only 20 values, in which case I would like the function to display the 20 values randomly sorted. Hi, I have a Javascript which I'm using to display one of four Flash SWF files randomly. These need to be actually displayed twice, so I'm basically calling the script twice. This works great aside from one thing- occasionally the same movie appears in both scripts, for example the first instance picks movie 3 of 4 and th second instance does the same. What I need is to somehow make sure that if the first instance of the script picks movie x then the second script will pick any movie EXCEPT movie x. This is the script as it stands: Code:
<script language="JavaScript">
// Generate a Random Number
var randomnumber = Math.round(Math.random()*3);
// Select a swf and execute the corresponding function
if (randomnumber == 1)
{movie1();}
else if (randomnumber == 2)
{movie2();}
else if (randomnumber == 3)
{movie3();}
else {movie4();}
//Functions to write out the correct flash movie resource.
function movie1(){
document.write("<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" codebase=\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=4,0,2,0\" width=\"120\" height=\"285\"><param name=movie value=\"assets/images/ads/hotels/1.swf\"><param name=quality value=high><embed src=\"assets/images/ads/hotels/1.swf\" quality=high pluginspage=\"http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash\" type=\"application/x-shockwave-flash\" width=\"120\" height=\"285\"></embed></object>")

Ok got a random image display and have tried to make it so once the image is displayed it is taken out of the array so it can not be viewed again untill there are no more elements in the array, problem is, it doesn't work. Have been told about shuffle, but not very keen on that. Can someone shed some light. 4 images, with accompaning links to be displayed 4 times, all unique. Code: Code: <script language="JavaScript">
function random_imglink(){
var myimages=new Array()
myimages[0]="http://ads.factorymedia.com/www/images/fbm_oct10_300x80.gif"
myimages[1]="http://ads.factorymedia.com/www/images/rbbyd_web_banner_300x80_animated.gif"
myimages[2]="http://ads.factorymedia.com/www/images/2010_vex_300x80.jpg"
myimages[3]="http://ads.factorymedia.com/www/images/image_3.gif"
var imagelinks=new Array()
imagelinks[0]="http://www.4downdistribution.com/"
imagelinks[1]="http://www.redbull.co.uk/cs/Satellite/en_UK/Event/Red-Bull-Backyard-Digger-021242831811513"
imagelinks[2]="http://verdebmx.com/"
imagelinks[3]="http://www.zealbmx.com/"
var count;
for(count=0; count<myimages.length; count++) {
if (myimages.length>0) {
var ry=Math.floor(Math.random()*myimages.length)
document.write('<div class="feed2"><a href='+'"'+imagelinks[ry]+'"'+'><img src="'+myimages[ry]+'" height=64px width=240px border=0></a></div>')
if (ry>0 && ry<myimages.length-1) {
myimages=concat(myimages. (0,ry-1),myimages.slice(ry+1,myimages.length-1));
imagelinks=concat(imagelinks.slice(0,ry-1),imagelinks.slice(ry+1,imagelinks.length-1));
}
if (ry==0) {
myimages=myimages.slice(1,myimages.length-1);
imagelinks=imagelinks.slice(1,imagelinks.length-1);
}
if (ry==myimages.length-1) {
myimages=myimages.slice(0,ry-1);
imagelinks=imagelinks.slice(0,ry-1);
}
}
}
}
</script>
<script language="JavaScript">
random_imglink();
</script>
an alternative way that also didn't work Code: function random_imglink(){
var myimages=new Array();
myimages[0]="http://ads.factorymedia.com/www/images/fbm_oct10_300x80.gif";
myimages[1]="http://ads.factorymedia.com/www/images/rbbyd_web_banner_300x80_animated.gif";

imagelinks[2]="http://verdebmx.com/";
imagelinks[3]="http://www.zealbmx.com/";
var indexes = [0, 1, 2, 3];
index.sort(function (){ reutrn 0.5 - Math.random(); });
for(var count=0; count < index.length; count++) {
var ry = indexes[count];
document.write('<div class="feed2"><a href='+'"'+imagelinks[ry]+'"'+'><img src="'+myimages[ry]+'" height=64px width=240px border=0></a></div>');
}
}
I have an essoteric question about javascript and how DOM/javascript stores divs that are created and displayed in succession by absolute positioning. I have a series of divs that are assigned absolute top and left values to form a grid. The grid tiles are programmed to swap coordinates in pairs when one of the pairs is clicked. Then if I do a sampling of the divs by: Code: //returns the same string on every call.
//regardless of the coordinate values. which change
var GM = document.getElementById('TP');
if(GM.hasChildNodes)
{
var GMC = GM.getElementsByTagName('div');
var str = '';
for(i = 0; i < GMC.length; i++)
{
if(GMC[i].hasChildNodes)
{
for(var j = 0; j < GMC[i].childNodes.length; j++)
{
var gmc = GMC[i].childNodes[j];
var gmcTxt = gmc.childNodes[0].data;
str += gmcTxt;
}
}
}
}
alert(str);
The list does not represent the positions of the divs as they appear in the browser, but in a sequence that is saved in another array when the divs are created. The same is true for document.getElementById('[id assigned each div]') The only way to detect the sequence is to do a long drawn out loop looking for coordinate values, and comparing them to a prestablish template set of values, then looping back through to compare the contents of each div and decide if they are in the right place (visually). The problem is that some divs may have the same content. If the same content appears to be in the right place, the coordinates can be wrong. So I need to detect the content and decide if it is right, regard- less of the coordinates. This has to be done by the program (of course). So the question is: What is javascript doing when it is asked to Code: document.getElementByTagName('[elem]');
In this case are the divs children of the document? (in the case of my project, children of a container div) And why would they not be detected in the order apparent in the browser window? I will post the current version and return and post a reply with the url. http://www.jekillen.com/jekillen/con..._wise_dev.html Well i want to implement something very similar to this (youtube). My javascript knowledges are low. I think it has something to be with onload and onclick events with links. Do i have to write a function and include it on the html page? Where do i have to put the diferent contents? I would prefer to separate html content and javascript since i have some variable to display from my template engine like {$name}, {$uploaded_date}, etc. Thanks in advance Hi all - first post - I'm not too hot on javascript so I don't know if this can be done nor how to search for it in the forum because I don't know what keywords to use - but if I give an idea of what I want to do, perhaps someone can suggest an idea of how to proceed? I have two left floated divs - in the left div I want a series of drop downs (possibly check boxes as well) about a series of products. When the user makes their decision and presses submit, I want the form to submit to a javascript function that says "Right, you will need, from your responses, product C" and in the right hand floated div, a series of hidden product info divs whose visibility is changed depending on which product the function determines is the one for you. Broken down into parts I think I need to do the following: a) Standard HTML form with drop downs etc and submit b) Hidden divs c) Submission process locally to javascript function to determine which product to show/hide d) Javascript function that makes the decision e) Javascript that hides/shows products Unfortunately a server side option is not available; it has to be a client side solution and I only could think of javascript. I can probably handle all bar c) and d) - any pointers, help or suggestions would be great thanks! cheers frank Hello all, hope all is well. I have a search function that displays hidden divs based on what the user has searched for. I would like the "search results" to be opened onto a new page; I have a feeling the results page would contain all the hidden divs and a form of JS would need to be used to "pass" the search data to the new page and thus perform the search and display the corresponding div. - Any help is appreciated here code and demo site below.

http://nctfleetlist.co.uk/div3.php So, I'm using a lot of js and I needed to find a work around to get it all working together, so I'm using InsertContent and RemoveContent to control several divs that I have. In this case it is 4 divs, but in other situations I'll have up to 10. My problem is that when the user starts with the first div displayed, the other 3 swap just fine, however, when clicking through the set of links, once the user gets to the 3rd link that is supposed to swap out the divs all the divs show up except the first, and the same happens on the fourth link. This is my js for the div swap functionality: Code: <script type="text/javascript">
<!--
function InsertContent(tid) {
if(document.getElementById(tid).style.display == "none") {
document.getElementById(tid).style.display = "";

Thank you in advance! 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">

Any suggestions? Thank you! 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?

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. 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! 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 Dear all, Appreciate your kind guidance and help in helping me to solve the following code. I wanted to generate a set of random number on the pinpad everytime the page is being loaded. (1-9 but the number can only appear once) How do I get about doing it? Sincere Thanks CAD Code: <html>

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 text file(quotes.txt) with 35+ quotations, separated by a single line break. Is it possible for a DIV to display a random quotation from quotes.txt each time the user visit my home page?
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? 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)); |
