Make A Random Number Between 1 And 1,000?

Jun 30, 2010

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)

Generates A Random Number Between 1-1000 And Then Allows The User To Make Guesses In A Text Box

Apr 15, 2010

I'm having to write a program that generates a random number between 1-1000 and then allows the user to make guesses in a text box, answering to high or to low, until the correct answer is entered. I had the program working fine with using strictly prompts and alerts but when I tried to create a form I started having trouble.

Create A Virtual Library - Make A Random Number Of Books Pop Out On Mouse Over?

Jun 7, 2011

I have a background that is a shelf full of books, I wanted to figure out what I would need to do in order to make a random number of books pop out on mouse over (individually), and upon click have the book pulled out and be flipped through and read like a book. Would I have to recreate the library picture completely to make the random books moveable? And would I have to create the books that I want to move from the bookshelf?

how to pull the book out from the book shelf so that it looks like it's coming towards me and then to make it look like it has been pulled out. Would I need to use animation for this? What would be the parts to the animation required?

A little background on my knowledge of javascript: I understand the concepts of it and can understand it when I read it or its explained to me. I am looking to create something as simple as I can, I thought having a background and something basic like a few books be able to pop out. When I realized css couldn't do this and css3 wasn't supported by most browsers I turned to javascript and have been trying to figure out the steps I would need to do to do this specifically.

JQuery :: If Number Is Below 5.5 Make It Red - Otherwise Make It Green - Multiple Classes

Dec 8, 2011

I have several classes named 'ratings_colored'. They all contain a number from 1 to 10. If the number is below 5.5, the number should become red. If not it should become green.

The code below works, but if the first .ratings_colored is higher than 5.5 it will make ALL the classes green. Even the numbers below 5.5! I tried using the 'this' but it didn't work either.

$(document).ready(function () {

Random Number But Only Once?

Aug 31, 2011

I'm trying to apply something in my forums, where a member could post something let's say:"Hi, I am number 1, 6"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.

Generating Random Number

Feb 28, 2006

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.

Regenerating A Random Number?

Apr 23, 2009

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.

Random Number Generation Different For IEs?

May 10, 2009

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).

Button Prints Out Random Number

Sep 23, 2011

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:

Code:
<script type="text/javascript">
function randomnumber(randomForm){
var x=Math.floor(Math.random()*11);
document.write(x);
}
</script>
<FORM>
<INPUT type="button" value="Print Number" name="button1" onClick="randomnumber(this.form)">
</FORM>

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?

Generate Random Number Within A Range?

Jun 30, 2009

I am trying to generate random number within a range. My code at the moment is

Code:

var uppermax = 100; var uppermin = 10; var upperdiff = uppermax - uppermin; var lowermax = 10; var lowermin = 0; var lowerdiff = lowermax - lowermin; var rand = Math.floor(upperdiff + 1) * Math.random() + uppermin; alert(rand);

I know math.floor is supposed to round down to the nearest integer, but the generator is still coming back with a float.

Create Random Number Between 1 - 50 With Decimals?

May 24, 2011

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

Displaying The Same Image A Random Number Of Times?

Mar 7, 2011

I'm trying to display the same image several times using javascript. It can range anywhere from 0 to about 50. I'll also have its' location determined by the user click and each image will timeout after a short period of time. I figure i'll have to create a new object for each image that is added and remove it after it times out, but my problem is I dont know how to tell the HTML code inside the <body> tag to display the same image for each click I make.
