I'm trying to find a way to play MIDIs generated at random in a web page. I don't mean picking a random filename and playing it, but actually constructing a MIDI in JavaScript and then playing it.
Now, I can get as far as making a string, or a byte array, or whatever, but is there a way to play it as a MIDI without it being a file? Or can I somehow save it, play it, and then delete it?
How do I create a cookie for storing a random number in it.

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>";

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('http://profile.ak.fbcdn.net/v225/1616/88/s1220771654_2158.jpg','http://www.facebook.com/addfriend.php?id=1220771654'),

For my website I would like to create a famous last words generator (randomized), and random page generator (within my site). What is the code for random quotes and random links?
View 2 Replies View RelatedI am new to javascript but have been using java for quite a while. I am looking to make a random quote (out of ten possible quotes) appear in my h2 tag in a page i am working on. In java, i would make a random number generator, in javascript it looks like this:
Code:
var randomnumber=Math.floor(Math.random()*11)
Then make an if statement:
Code:
if randomnumber=1 {
var quote="Live long and prosper"
}
document.write(var quote); Could someone more experienced than me tell me if my code looks good and how would a go about getting "var quote" in my h2 tag?
How would I go about this? I found this piece of code, but this only allows
two links. Does anyone know how to expand on this to add 10 or more?
<script type="text/javascript">
var r=Math.random()
if (r>0.5)
{
document.write("<a href='http://www.w3schools.com'>Learn Web
Development!</a>")
}
else
{
document.write("<a href='http://www.refsnesdata.no'>Visit Refsnes

}

I don't know if this is easy or not, I have no clue on how to start it.
I have Seven different states.
I will be having a form with 7 textboxes, and I will enter 7 different
states each time in the textbox.
When I click on the button, it would call a function
the function would output :
6 different combinations of 3 states. So I would have 1-6 and for each
would list three states I entered in the textboxes.
How can i manage it (html or jscript with css) that everytime a user loads
or refreshes a page, the page has a new bgcolor.
I want to put it in a single file, so that all my pages have the same color,
but after every refresh a new random one.
I'm new at Javascript, and have written a script for a series of random
roll-over button images, but one thing I would like to add is a function
that checks to make sure that there are no duplicates in the randomly
generated variables that choose the pictures.
Can anyone give me a hand with this? One other thing I can't seem to figure
out is how to manage the "onLoad" aspect of caching my roll-over images (DW
has locked the <body onload> function into a template, so I can't mess with
it...). so my rollover graphics are grabbed from the server in "real time"
during mouse-over, which is a bit "goofy" and "slow" in terms of instant
rollover effect. I'm sure that there is a much more efficient way of doing
this, but I've been able to learn a lot by tweaking DW's way of doing
things, so it's not a total loss.
In an external JS file, I set up a series of 10 random variables using the
Math.random and Math.round functions like so:
var btn0 = Math.random()*100;
btn0 = Math.round(btn0);
var btn1 = Math.random()*100;
btn1 = Math.round(btn1); .... etc for 10 buttons
Then in my page, I piggy-back onto Dreamweaver's built-in roll-over
handlers, like so (to write the instances of each rollover image);
<script>document.write('<a href="link1.htm" onMouseOut="MM_swapImgRestore()"
onMouseOver="MM_swapImage('pic1','','images/btns/'+btn0+'b.jpg',1)"><img
src="images/btn/'+btn0+'a.jpg" name="pic1" width="80" height="100"
border="0"></a>');</script>
For this particular page, I'm pretty much stuck with DW's coding because
it's locked into a template that governs my site navigation. Thanks for any
pointers or help ...
I've found examples of bookmarklets that select a URL from a page at
random, but I'd like one that generates part of the URL at random.
If you have a bunch of images that are named:
mydomain.com/images/abcd.jpg where abcd is can be any combination of 4
lowercase letters - is there a way of having the bookmarklet generate
the letters randomly when clicked?
I'm able to do it using AppleScript & Safari but would like it to work
from within Safari - which is missing the "Scripts" menu that most Apple
apps have :(
It looks as if bookmarklets are the only option, but I've only ever used
javascript to select randomly from existing arrays of images and don't
fancy typing in the names of a couple of thousand images...
I am trying to do is have:
1.) the background color to change randomly with 5 different colors.(change
on page load)
2,) 10 different quotes randomly fadeing in and out in random spots on the
webpage. with a delay timer on them, so they keep changing as the page is
open. Not random each time the page is loaded.
I remember there is a programming language where you can initialize the
random number generator, so that it can - if you want - give you the exactly
same sequence of random numbers every time you initialize it with the same
parameter. Can this be done with JavaScript? I couldn't find anything in the
documentation. Basically, what I want to achieve is to obtain always the
same sequence of random numbers for the same given initialization value (but
of course different sequences for different init values).
Can this be done in JavaScript?
Problem: I have three containers (divs) all with different background images assigned via a class. Each div will contain a background image displaying a different product. I'd like these three divs to randomly assign a class via JavaScript.The problem I'm running into is preventing the same class from being assigned twice to two divs on the same page load. Then you'd have two divs with the same background image.

I can generate a random number between 1 and 9,
( var rand_no = Math.floor( 1 + Math.random() * 9 ); )

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.
