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

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.

Resoloution Checker

Mar 10, 2005

Mixture of PHP & JavaScript as you can see.

|Style Chooser |
$style = $_GET['style'];
$res = $_GET['res'];
IF ($style == "") { $style = "v2-green"; }

IF ($res != 1024)
print "
<!-- Begin
function redirectPage() {
var url640 = "?res=640";
var url800 = "?res=800";
var url152 = "?res=1152";
var url1280 = "?res=1280";
var url1600 = "?res=1600";
var urlnorm = "";

if ((screen.width == 640))
window.location.href= url640;
else if ((screen.width == 800))
window.location.href= url800;
else if ((screen.width == 1152))
window.location.href= url1152;
else if ((screen.width == 1280))
window.location.href= url1280;
else if ((screen.width == 1600))
window.location.href= urll600;
else document.write(urlnorm)

// End -->

Date Checker?

Feb 27, 2006

I not much of JavaScript Developer, I'm a member of the copy and paste JavaScript Generation, so perhaps someone can tell me where I'm going wrong with my function to compare two dates:

if (Date.parse(dt1.value) >= Date.parse(dt2.value)){
alert("Departure Date must be After Arival Date")
return false

return true

The problem seems to be that two date values are been compared as strings, how can I force them to be compared as dates. I thought the Date.parse() function would handle that.

Simple PostCode Checker - Can't See For Looking

Feb 9, 2009

You're going to look at this code and see straight away what's wrong with it, but I've been staring at it for too long that my brain just isn't reading it right.

It's a basic input, you type in your postcode, if it is in the list of postcodes I entered then it replies with a 'Yes' response, otherwise a 'No' response. Unfortunately it keeps saying 'Yes' to anything that's entered.

Here it is, and apologies again for it being annoyingly simple, you know when you've been looking at code too much and you just can't see the small things anymore. [input type.needed=coffee]

Upto Date Syntax Checker ?

Nov 12, 2010

I have come across javascript lint but it seems to be a bit outdated... is there a more up to date syntax checked for javascript or does javascript lint still do the job?

There are several online tools I have seen but unfortunately these are no use as I need to be able to run it from the command line and (hopefully) be able to import it into vim.

Online Javascript Syntax Checker

Jul 2, 2002

I have a whole heap of Javascript that I want to compress (by removing line breaks etc). When laid out with line breaks, all works fine. When compressed ... BANG!

I suspect that there is a semi-colon missing somewhere which is only breaking when the return is removed. However, I'd like to run the whole block of javascript through an online validator instead of straining my eyes trying to locate the piece of the script at fault.

Is there such a thing? When I search for 'Javascript validator', I get a whole heap of links to using javascript to validate forms and such like!

Custom Menu CSS Class-Checker Script Not Running

Nov 15, 2009

I'm building a simple custom dropdown menu for a web-site so that I can control look and feel as well as the behavior of an iframe.I've set it up so that when the user clicks on any of the menu's active components, an "if" sequence in the clickHandler() function is activated that gets the element's class. If the event occurred on a dropdown option, the event-target id is checked, and the appropriate function is called. At least this is how it's supposed to work.All of the drop-down options have been assigned the "dmo" class. When I test the menu and click on other elements, it works fine. But when I click the "dmo" drop-down options, nothing happens. Firebug and IE Explorer Developer Tools both show no errors, but on clicking a dropdown option, the correlate code doesn't run at all, and after hours of head-banging, I have no idea why.

Count Checker - Track Of How Many Chars Are In A Field On An Asp Form

May 19, 2010

I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button?

I am including the code I have.


counter in code


I have tried

It compiles but the value remains reset.

Compiler/Checker - Notepad Or Firefox's Source Viewer Doesn't Indicate Anything

Mar 19, 2008

I'm new to Javascript but not new to programming.

I find JS more time consuming because I have to manually search line by line for a single error. In C++ or C the compiler tells me the exact line number of the error or at least what the error is so I can research it.

With JS, notepad or Firefox's source viewer doesn't indicate anything. Is there any software available that will error check JS codes?

Random Photo + Rotation Query - Continue From The Random Image And Change To The Next Every 3 Seconds?

Aug 31, 2011

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>";

Prevent Repeating In A Random (Math.random) Array?

Aug 6, 2009

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('',''),
new Array('',''),
