Starting Image In Random Array?
May 15, 2010
I'm creating a tool which will who a random image every time I press a button, when the image is clicked it will open a new tab which will show a website. I can tell you I've succeeded in all this, but I was wondering if there is any way in which I can let my "generator" show 1 standard image at first, and if this is even possible never show that image after it has been showed. The image will explain that the you have to press the button to go to the next image.The Code:
<script language="JavaScript">
images = new Array(4);
images[0] = "<a href = 'URL' target='name' onclick='window.open ('URL')' ><img src='img1.jpg' alt='tag'></a>";
[code]....

Is there a quick jQuery one liner to return (as an array) all class names that start with "{insert_string_here}"The equivalent of the following:
Code:
var response = $( "*[class^='arete']");
var myClassArray = [];
for( var ix=0; ix < response.length; ix++)

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:
<script type="text/javascript">
var vip_list=new Array(
new Array('http://profile.ak.fbcdn.net/v225/1616/88/s1220771654_2158.jpg','http://www.facebook.com/addfriend.php?id=1220771654'),
new Array('http://profile.ak.fbcdn.net/v223/1233/29/s904885342_9055.jpg','http://www.facebook.com/addfriend.php?id=904885342'),

I'm trying to use Javascript to have an array of images that load randomly AND work in a slideshow manner so change every 3 seconds (in a logical order). The code I have below presents a random image but how do I get them to continue from the random image and change to the next every 3 seconds?
<script language="JavaScript">
images = new Array(3);
images[0] = "<a href = 'photo1.html'><img src='images/photo1.jpg' alt='Photo 1'></a>";
images[1] = "<a href = 'photo2.html'><img src='images/photo2.jpg' alt='Photo 2'></a>";
images[2] = "<a href = 'photo3.html'><img src='images/photo3.jpg' alt='Photo 3'></a>";
[Code]...

I'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.

I've been searching for a resolution to this issue for hours trying to customize my page located at [url]
Specifically, I'm trying to figure out why this line of code is not making my images display in the background:
Original plugin script provided here: [url]
<script>
I made adjustments with my image references that are all located in this directory: [url]
Problem: No images load, and I believe I don't fully understand the .appendTo tage.. I don't know if #body is correct. The author of the plugin assumed I understood the relation. Also #homePage may be incorrect as well.
Additionally, I found another plugin that worked for placing an image in the background (not random), and the background image would scale to size, according the users window. I loved that and it worked, just wanted to add random images to the same script.... first things first... I can't even get an image to display at all with the above code.
In case you wanted to know the script I was using to scale the background image, here it is below (although, as you will see in the code for my site - this image feature is disabled as I am trying to make adjustments).
code for image solutions used:
HTML
CSS
If I can get this second code to work with the random image plugin.

Here's what I usually use and have been using for years and it works great, just not for this particular purpose. I don't have a clue when it comes to javascript.
<noscript><img src="no_script_quote.gif" width="406" height="94"/></noscript><script language="javascript">
var delay=6000
var curindex=0
[code]....
But, now I want to be able to set a default picture to be shown first and have the random pics appear next. I also don't want the default pic to show up again in the random array. So basically, every time the page was first visited, or refreshed it would show the default picture then move into the random pics.

I am learning Javascript from this book I got, and I am trying to do one of the "challenges" in the Hangman example, and that is to add on more 8 letter words to it and have it select by random. I am assuming that it's asking me to do this with arrays, but I have no idea how to implement that on this while having it select randomly.

I have an array containing 100 different values. How would I randomly pick 25 of them for display? For now I do: 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. PS. My array could also contain only 20 values, in which case I would like the function to display the 20 values randomly sorted.

So, I am attempting to select a random entry from an array, and then make it so that particular entry will not be selected again until every entry has been selected. Basically, I don't want to see any of the same entries, until all of the entries in the array have been selected.
So if this were my array....
keywords =
[
"ppc",
"games",
[Code]....
since meta was selected a second time before everything had been selected once.
I would like to see something more like
meta, advertise, gaming,ppc, welcome, home, games, advertise, ppc, since this did not select any entry multiple times before every entry had been randomly selected.( the second loop started at the second "advertise" in case you didn't catch the differences.
But as you can see from the code that I have posted above, I do not know how to do this. I have seen examples where the entries that were randomly selected, were actually deleted from the array entirely but this is not what I want to do. I just want every entry to be selected once, and then for the process to be restarted.

does anyone know how to scramble the "box#" in the codes below? Ultimately, I want the checkboxes to be in different order each time I access the web page?
<script lanugage="javascript">
function countChoices(obj) {
max = 3; // max. number allowed at a time
box1 = obj.form.box1.checked; // your checkboxes here
box2 = obj.form.box2.checked;
box3 = obj.form.box3.checked; // add more if necessary
box4 = obj.form.box4.checked;
box5 = obj.form.box5.checked;
count = (box1 ? 1 : 0) + (box2 ? 1 : 0) + (box3 ? 1 : 0) + (box4 ? 1 : 0) + (box5 ? 1 : 0);
if (count > max) {
alert("You can only choose " + max + " of the 5 nominees.");
obj.checked = false;
}
}
</script>
<form>
<input type=checkbox name=box1 onClick="countChoices(this)"> Homer Simpsons <p>
<input type=checkbox name=box2 onClick="countChoices(this)"> Ground's Keeper Willie <p>
<input type=checkbox name=box3 onClick="countChoices(this)"> Mr. Burns <p>
<input type=checkbox name=box4 onClick="countChoices(this)"> Barney <p>
<input type=checkbox name=box5 onClick="countChoices(this)"> Chief Wiggum<p>

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?
Ex: array 1: 25, 34, 38, 40, 22, 49
Want to move numbers between 30 and 50 to another array.
array 2: 34, 38, 40, 49
Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)

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.

I've been asked to do the following using javascript:
-Create a function named randInt() with one parameter of "size". Declare a variable named "rNum" equal to a random integer between 1 and the value of the size variable. Return the value of the "rNum" varialbe from the function.
-Create a function named getQuote() with one parameter anemd "qNum". The function should create an array named mtQuotes with five quotes; there should be no quote for the array index "0". Return the value of the mtQuotes array for the qNum index.
- In the div element of "quotes" insert a script with the following commands: Declare a variable named "randValue" which is euqal to a random integer between 1 and 5 (use the randInt() function). Declare a variable named "quoteText" containing the quote whose array index value is equal to randValue. Write the value of quoteText to the web page.Here is what I have...it returns undefined.

I have an array and a button to select a random integer from the array, how do I make it so that it selects every integer once til all are selected, then it starts over again?For example, an array has these:
A
B

Q
F
So you press the button a number of times, and you get:
Q
B
1
F
A
2
Instead of:
1
Q
A
1
B
A
