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.

How To Generate A Random Page In A Frame

Jan 13, 2011

So to start out, this is my first post on CodingForums! :) I've only recently started learning web development so I figured it would be a good idea to get involved with some active forums.

I am trying to open a random page in a frame, but I am trying to call the Javascript to do so in another frame. I currently have an html page with a frameset which has two frames. One of the frames is a toolbar that sits at the top of the page and it has an image that acts as button. When the user clicks on this image, the bottom frame generates a random page from an array of links I have hardcoded into the Javascript. The bottom frame is just set to google.com as a default because I couldn't really think of anything to put in an html file there.

The problem I'm having is when I click on the image to open a random page in the bottom frame, nothing happens. The code for all the files are below. code...

Random Page Be Loaded Without A Prior Visit To A Site?

Sep 13, 2010

Can a random page be loaded without a prior visit to a site?

I have a list of 15 people with a photo and contact information in a table with 3 columns and 5 rows. The issue is that the people near the bottom want a chance to be at the top the first time the page is viewed. It is unlikely that a second visit would happen.

Is this possible to load a random page for a site without it being viewed or logged into before, therefore no cookies will be used.

Random Background Images Every Time Page Loaded

Jan 27, 2011

I have a client that wants a new background image every time page is reloaded. I thought I have to script and thought I had it working but when I applied it to all my pages from a template I made in dreamweaver it doesn't work. It only works on the template.

See code below.
<head>
<script type="text/javascript">
<!--
function MM_goToURL() { //v3.0
var i, args=MM_goToURL.arguments; document.MM_returnValue = false;
for (i=0; i<(args.length-1); i+=2) eval(args[i]+".location='"+args[i+1]+"'");
}

function MM_displayStatusMsg(msgStr) { //v1.0
status=msgStr;
document.MM_returnValue = true;
}
//-->
</script>
</head>
<body>
<script>

var randombgs=["../images/main_background.png", "../images/main_background2.png", "../images/main_background3.png", "../images/main_background4.png", "../images/main_background.png", "../images/main_background2.png", "../images/main_background3.png", "../images/main_background4.png"]
document.write('<body background="'+randombgs[Math.floor(Math.random()*randombgs.length)]+'" bgcolor="#FFFFFF">')
</script>
</body

} document.questions.result.value = response ;
} function randoms() {
rndNum = Math.random();
Num = rndNum*20;
Num1=rndNum*10
document.write(Math.round(Num)+"+"+ Math.round(Num1));
} function adding() {
document.write(Math.round(Num) + Math.round(Num1)); }
</SCRIPT></HEAD><BODY>

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?
