For a computer science class homework assignment I need to create a page where an image changes randomly when a button is clicked. This is what I have so far, nothing happens when button is clicked. I need the button to randomly return one of the five images described in the emotions function. Please help, I sorely need it.

I'll get to the point, I'm a noob I'm using greasemonkey for a certain website. Basically, I'm using gm to refresh the page after a certain time, I was however wondering, If I can set it to a random number between 2 specific times?
The code I'm using atm is setTimeout(function() { document.location.reload(); } , 10000); I know I have to use math.random, well, I think I do. But I'm not sure how to do it between 2 certain times? So to summarise, I'm trying to refresh a page at any given random time between say 5-10 minutes.
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.
I run a random number generating service for a RPG message board I go to, and my website generates only numbers from 1-100. How could I script this so that the user can get random numbers between 1-X?
I want a certain amount of image spots to show a certain set of images (specifically 8) in a random order every time the page is refreshed. I do not want the images to be repeated, however. The solution I came up with was to create an array and generate a number one to eight and then compare that number to the numbers previously in the array, and if it matched one that was previously generated, to generate a new number and then compare it. This continues until i have an array of the numbers 1-8 in a random order.
var imgs=new Array(8); for(i in imgs) { function generate() { return Math.floor(1+Math.random()*8);

This does not strike me as the most efficient way to go about this. If someone has a better solution,
New to JS, and not too good at it. Trying to take some prewritten code and add script that displays some random text. Having trouble with assignment. Instructions are to replace a section of the file I am given with a script element. In the script element I am suppose to declare a variable named tipNum equal to a random integer between 1 and 10 returned by the randInt() function (which I made and have shown below). Then I am suppose to use a series of document.write() methods to write the following HTML code into the page:
<h1>Random Tip<br />title</h1> <p>tip</p>
(Where "title" is the title of the random text as generated by the tipTitle() function from a external file, and which I did not make; and "tip" is the text of the random tip as genereated by the tipText() function, which is also from the external file, and not made by me) My code for the randInt() function is
function randInt(lower, upper) { var size = ++(upper - lower); var randValue = Math.floor(lower + size*Math.random()); }
The script I made to display the HTML code is

I am getting nothing on my page where the random text should be.
I want to display a 'preview' image for a file upload field. I assigned a function to the onChanged event for the file input that gets the value of the input text field, does some minor regex to fix the string, and then creates a new 'img' tag element and assigns the fixed string as the img's src: Code:
I found this code in another thread... basically, I need to be able to display a certain image based on the page's title... for instance if the title is: Lotus 7, I need image lotus.jpg to display in an element on the page, however, if the title is Bodhi 9, I need image bodhi.jpg to display in the same element
var imgs = new Array(); imgs[0] = new Array(); imgs[0][0] = "Research";
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?
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'm completely new to this and have no knowledge at all when it comes to javascript. Have been using this script on my site for a while. Is there anyway I can add a URL link to the images that are in my selector? When clicked would go to that page on my website.
<script language="JavaScript"> /* Random image slideshow- By Tyler Clarke (tyler@ihatecoffee.com) For this script and more, visit http://www.javascriptkit.com */ var delay=10000 //set delay in miliseconds var curindex=0 [Code]...
I am using a module called mod_pageear in my joomla based site that displays an image in the page when the trigger is scrolled over. I would like to change the code to access images in a folder on a random basis. The existing section of the code that accesses the single image is as follows: Code:
I have a page on which a random image loads. Each image needs an accompanying image map to take you to the appropriate link. How do I make the appropriate image map links load? Here is my code so far, which works fine.
myStrip = new Array("images/hstrip_1.jpg","images/hstrip_2.jpg"); imgCt = myStrip.length;
function chooseStrip() { if (document.images) { randomNum = Math.floor((Math.random() * imgCt)); document.strip.src = myStrip[randomNum]; } }
I'm hoping that someone can answer what is probably a really simple question. I've got the Random Image Slideshow script from javascript.com and have it placed in my site where I want it. Now how do I get it to read where I've got the images I want displaying? The folder I have is called homeimages with 10 photos currently inside it.
im having a dumbass problem its probably something stupid as it always is with me. Basically ive incorporated a javascript random image background. It works however it occasionally displays a WHITE bg, as if its trying to link to one of the images in the array and its not there. To get what i mean view the link below and click REFRESH until it goes white. Code:
I've got an array of images that I want to randomly attach themselves in some <li> tags. Right now I've got everything working great except the images repeat sometimes repeat themselves.Is there any way to make the images not repeat?Here's the code:
Code JavaScript: // Random Image var theImages = new Array()
i have a script that is close to working, but not quite. it loads 1 of 9 random images on pageload with the corresponding link on the image. that works fine. i am trying to also get the corresponding copy to appear next to it, but it seems to be totally random as well and not matching up with its proper image (for example, if image 5 loads, then copy 5 should be the one that loads). below is what i have.
HTML Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Another slightly different random image question. My coding is working fine in Safari (mac) but all that shows up in IE6 is the caption, not the image itself.
Code: function randImgCap() { var banner = new Array(); banner[0] ="images/robpics/After_Fire.jpg" banner[1] ="images/catepics/2tight.jpg"
I need to get this done for multiple images - let's say I have 5 places at the same time for a random image to appear, but they mustn't repeat! I don't mind manually selecting images for a certain spot, but it should be declared in another file (rather than the html).
i need to display an image randomly from an array that holds 4 addresses to 4 different images.i am having a hard time writing the img tag to the html page that will display the image.is it possible to use document.getElementById('id').innerHTML= "<img src="imgurl" />"?i have a span with an id of "theImage".i want to plop the img tag inside this span tag, but can't seem to get it to work.
