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.
I set myself the task of creating a button which, when pressed, switches the background color randomly. It seems to work well enough but the random number it works from only generates once at page load.As a workaround, I added a second 'Reset Page' button, but I really want just one button that switches the page color every time you prod it. Any ideas how to reset the random number to achieve this?Here's the code.

I am trying to make a random number between 1 and 1,000. I have a code that seems to work correctly, but I don't completely understand it and after looking online I think it might be wrong. Code: var rnd = Math.floor(Math.random()*999)
All the numbers should match. It's not working right in any version of IE I test it in (6, 7 and 8). I'm also using jQuery, fyi.When you click the button to stop the numbers, I'm setting a variable named winner to a number (3, 4 or 5). Right now, I have it set to 5. This number determines how many of the slots match:[code]I'm then generating a random number (0-8) to base all the other numbers off of . Three numbers will always match, so I'm setting two more variables to match that random number.[code]Then I do some conditionals to check the value of winner. If it's 4, I set the 4th number to random number, then generate a random number for the 5th spot while it doesn't equal randomnum. I do something similar if winner is set to 5.[code]The goto trigger sends the scroll to the specified index according to slotnum(1-5).I'm waiting to hear back from the plugin developer to see if it's something to do with that.However, I just want to make sure my logic in generating those numbers is sound. It works perfectly in FF, Opera and Chrome but (surprise!) not in any of the IEs (tested in 6, 7 and 8).
I am trying to make it so that when you press a button it prints out a random number. This is what I currently have:
When I click on the button it just clears all the text from the page and clears the bgcolor. A random number then appears at the top left corner. I am trying to make it so that when I press the button it prints out a random number just above or below the button. Is this possible? if so how do you set it up?
How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place? Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2
Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well Ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200
I have a form and select menus. I am posting it ajax post method and loading the same page with load method as you see in codes. There is a random number genarator. I want to change this random number once a click submit. If i do not load the same page this number does not change. Therefore I use both post and load methods like in demo. However when i do like this there is a problem which is random number have been generated twice somtimes. If you click submit button successively you will see that the number on left top corner sometimes changes twice a click. Why it is so and how can i correct it.
I am trying to generate a random number each a person visits a page but would like that number to not change if they leave the page and use their browser back button to return. My code is below and the problem I have is that upon browser back the value in the if statement is still "Null" despite having been changed the first time the script ran.....
The following code is supposed to provide a different alert message when a page is loaded, based on a random number generated on load. Can anybody see what is probably a very obvious problem that I just can't see?[code]
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..
i'm trying to write a code that generates a random number between 1 and 9999 on page load, concatenates it with "pwn" at the start, and adds it to a disabled form text input box. this is the code i have below, but it's not working at all.[code]
