JavaScript - Random Start Position Of Multiple Elements
hi,
I am now building my website as a final project for my year. I am doing graphic design, so the website is actually some kind of portfolio. The idea of this website (which is not yet online) is this : it is some kind of big pasteboard on which i will display all the work i have done in my academy since a couple of years. The pasteboard is at the moment a background image/color field of given dimension (i figure that was the only way to do what i wanted...see further) Every works/image load on a random place and then can be dragged, and dropped (this part i already figured out). At the moment, every image (for every project), is inside a <div>. What i need help for is this: at the moment, my function successfully load 1 element at random position. I now want this function to work separately, for every <div>, so that every image is randomly placed on load, on the background image (and not the browser window, which is smaller). Here is the code i have for the moment (sorry for the mess, i really am just beginning! and truely, i don't get half of this, i just know it is working at the moment): Code: <head>
<!--// function random start position-->
<script>
var aDOM = 0, ieDOM = 0, nsDOM = 0; var stdDOM = document.getElementById; if (stdDOM) aDOM = 1; else {ieDOM = document.all; if (ieDOM) aDOM = 1; else { var nsDOM = ((navigator.appName.indexOf('Netscape') != -1) && (parseInt(navigator.appVersion) ==4)); if (nsDOM) aDOM = 1;}}
function xDOM(objectId, wS) { if (stdDOM) return wS ? document.getElementById(objectId).style: document.getElementById(objectId); if (ieDOM) return wS ? document.all[objectId].style: document.all[objectId]; if (nsDOM) return document.layers[objectId]; }
// More Object Functions
function setObjVis(objectID,vis) {var objs = xDOM(objectID,1); objs.visibility = vis;}
function moveObjTo(objectID,x,y) {var objs = xDOM(objectID,1); objs.left = x; objs.top = y;}
// Browser Window Size and Position
function pageWidth() {return window.innerWidth != null? window.innerWidth: document.body != null? document.body.clientWidth:null;}
function pageHeight() {return window.innerHeight != null? window.innerHeight: document.body != null? document.body.clientHeight:null;}
function posLeft() {return typeof window.pageXOffset != 'undefined' ? window.pageXOffset:document.documentElement.scrollLeft? document.documentElement.scrollLeft:document.body.scrollLeft? document.body.scrollLeft:0;}
function posTop() {return typeof window.pageYOffset != 'undefined' ? window.pageYOffset:document.documentElement.scrollTop? document.documentElement.scrollTop: document.body.scrollTop?document.body.scrollTop:0;}
// Random Position Script
var xxx = Math.floor(Math.random()* (pageWidth()-230));
var yyy = Math.floor(Math.random()* (pageHeight()-50));
function start()
{var x = (posLeft()+xxx) + 'px';
var y = (posTop()+yyy) + 'px';
moveObjTo('myobj',x,y);
setObjVis('myobj','visible');}
window.onload = start;
window.onscroll = start;// JavaScript Document
</script>
</head>
<body bgcolor="#9A9B95" background="../website/background.jpg">
<div id="myobj" style="position:absolute" >
<img src="oblique strategies holes.jpg" width="595" height="842" style="position:absolute" class="dragme"/>
</div>
<div id="div2">
<img src="oblique strategies choices.jpg" width="842" height="595" style="position:absolute" class="dragme" />
</div>
</body>
now, what i really want is this function to work for every <div> but i know there are also some flaws (that i'm unfortunately unable to fix myself): the integers "230 and 50" in the "random position script" should be replaced byt the width and heigh of the image/div (so i guess i should find a function that can get those numbers, name them "ImgWeidth" and "ImgHeigh" so that those integer can be called in this "random position" function. also, once the div 'myobj' is loaded, randomly, it behaves like if position=fixed (so stays on the spot when i scroll down the window). I think this is because it calculates the position according to the browser window and not my background. this has be fixed, because i don't want all my images to load only in the browser window (but on the whole pasteboard/background image). well, i guess this is already 3 questions in one. so i will let it like that for the moment. Sorry if i'm saying too much/not enough... beginners mistake!:confused: thanks in advance for any help you will give me! Similar TutorialsI basically want a random image to show up on my webpage and start scrolling through more images i've set to that list. Here's what I have thus far. However, It'll always start by bringing up the same image and then change to an error image: Code: <html>

Here's the Website I'm having problems on (So you can visually see what I mean - Under "TV ManiaX Home Page sub-heading): http://tvmaniax.myfastforum.org/index.html Thank you for any help you can give _________________ Hi, I have a dynamically generated list of which contain div's with a class of product. I want to only display 6 random products out of the whole list on page load and hide the rest. I am quite new to javascript so some help would be much appreciated. Thanks What I am trying to do is make a little box that when you hover over it, it will move to a random position. What I am having trouble with is the JavaScript. I have made the code for everything, EXCEPT to move it to a random position. Here is my code so far: Code: <style type='text/css'>
#circle1 {
background:#007fff;
height:20px;
margin:0px;
position:absolute;
width:20px;
left:5px;
top:5px;
-webkit-transition:left 2s linear, top 2s linear;
}
#circle1:hover {
left:25px;
top:25px;
-webkit-transition:left 0s linear, top 0s linear;
}
</style>
<div id='circle1'></div>
I would like the left: and top: in the #circle1:hover to be a random number, to make it go to a random position. I have no clue how to do that though... How would I generate a random number between 0 and 470 at multiples of 10 including 0 and 470?
Hi, I've got a game 99% finished, basically when the game start and the player clicks through to the game panel, there are 30 tiles (80x80px) each, and the object of the game is for the player to press the tile with the letter "X" on, the X can be on any 1 of 5 different coloured tiles at anyone time and of course there can be more than 1 tile having an X on it. The tiles currently are built via .css, and this works 100% perfectly. However now I want to use images, pulled in from my local website instead of tiles built via .css. A demo of what I'm kinda of after is here > Edit fiddle - JSFiddle - if you press "run" the images will keep changing their order. The code I currently have for the game is here.. //CODE// var TheColorArray = ['red', 'yellow', 'green', 'blue', 'orange'], TheScore = 0, TimerLength = 2500, GameTimer, ScoreMap = { 'red': 500, 'yellow': 50, 'green': 30, 'blue': 20, 'orange': 5 }; function DrawRow() { TheColorArray.sort(function () { return .5 - Math.random(); }); var TheHTML = '<div class="row">'; var MagicColumn = Math.floor(Math.random() * 6); for (var i = 0; i < 5; i++) { if (i === MagicColumn) { TheHTML = TheHTML + '<div class="GameTile ' + TheColorArray[i] + '">x</div>'; } else { TheHTML = TheHTML + '<div class="GameTile ' + TheColorArray[i] + '">' + String.fromCharCode(97 + Math.floor(Math.random() * 26)) + '</div>'; } } TheHTML = TheHTML + '</div>'; return TheHTML; } You'll also see that "TheHTML = TheHTML + '<div class="GameTile ' + TheColorArray[i] + '">x</div>';" and "TheHTML = TheHTML + '<div class="GameTile ' + TheColorArray[i] + '">' + String.fromCharCode(97 + Math.floor(Math.random() * 26)) + '</div>';" both state that if X is pressed the game basically carries on. I need this to use a chosen image from my server, i.e. URL/apple.png .... i have also managed to get to this point (with apples) but its just not working.. Edit fiddle - JSFiddle Any help would be great.. Many thanks in advance!!! Hi I implemented some coding tor create a random image on the page with a corresponding 'alt' tag and all was fine for a while... Then I got ambitions and modified the script to generate code that would generate two seperate sets of random image and associated 'alt' tag pairs.... and all seemed fine for a while.... ... however after having used the code on my page for a while I notice that occasionally I get a broken file link to the image which then fails to show... and shows the 'alt' text of "undefined". All the code links to images are correct and all images DO show from time to time with the tags.... only occasionally this extra blank/undefined pair is generated. Anyone have any ideas?

I have a script which allows me to select random users from one select field to another and works like a charm, but... I want to be able to get random users from one select field to multiple (lets say 2) other select fields... So lets say that I have 5 users in the first field (select1): James Bill Jennifer Bob Karen Now when I press a button: <input value="" type="button" onClick="randomusers();" /> 2 users should be moved to select2 and other 2 users moved to select3. My current script is as follows: Code: function randomusers(){
var given = 2, used = {}, randnum, opts = $('#select1 option'), olen = opts.length, hiddiv = $('#hiddendiv');
function ran() { // generate a unique random number
randnum = Math.floor(Math.random() * olen);
return used['u'+randnum] ? ran() : randnum;
}
for (var i = 0; i < given; i++) { // get the correct quantity of randoms
used['u'+ran()] = true;
}
var players = opts.filter(function(index) { // remove all options that are not one of the randoms
return !!used['u'+index];
}).appendTo('#select2');
}
Hoping for help... Thanks in advance :-) Hello, I'm in need of some help. I have a form that I want to clone and add up to 5 duplicates with slight changes. The changes a Add a second question and another set of related radio buttons for only the duplicates. Change the title in the Header to increment by 1 ex. Header 1, Header 2... I also would like to make the form elements "id" and "names" unique. Also, continue to use the add and remove button at the bottom. I hope this is doable. Any help will be appreciated.

-Cheers Normally I would just use document.getElementById to get anything I need but here is my problem: I have a zip code control that I load using AJAX. it has city, state, country, county and zip code. This gets loaded within a business application and at one point you can have both a bill to and ship to address forms on the screen at the same time, loading my zip control with the same fields, same ids and same name. This forced me to now pass in the form name that contains the control. I need to get to divs and spans within this form. Primarily as you type in a city or zip code, I am doing a hot search with a popup div that shows you results you can quickly choose from. The only time this becomes an issue is the situation I mentioned before when the zip code control is on the screen twice. I am not certain how to access the innerHTML of a span or div by way of the form name. Is this possible and if so what is the proper syntax? Here is a very basic example at its simplest form of my problem. Code: <form name="frm_billto" id="frm_billto"> <span id="myspan">Hello</span> </form> <form name="frm_shipto" id="frm_shipto"> <span id="myspan">World</span> </form> In the above example because the control was loaded twice, I now have 2 spans with the same ID. I want the innerHTML of the each span based on the form they are in. We wanted one control that we could use throughout the system that we could update in one place and the entire application be updated. Unfortunately we did not anticipate having it load more than once on the page. Thank you for any help I'm having a problem with the <CANVAS> element in JavaScript. here's what i'm trying to do: I need 3 different canvas elements for writing a signature to. they must all 3 be visible at the same time My problem that i'm having is that i can't seem to get the code to work which will write to more than one canvas. here's my code: Code: <html>
<head>
<script language="javascript">
function WriteSignature(element, event)
{
document.addEventListener("mousemove", PenHandler, true);
document.addEventListener("mouseup", upHandler, true);
event.stopPropagation();
event.preventDefault();
function PenHandler(event)
{
var x = event.clientX;
var y = event.clientY;
// mouse event goes here
var canvas1 = document.getElementById("Canvas1");
var ctx = canvas1.getContext("2d");
var PenSize = 2;
ctx.fillStyle = "Black";
ctx.fillRect (x, y, PenSize, PenSize);
event.stopPropagation();
}

Hi, I'm currently trying to incorporate several random link generators on one page, each with different links to be directed to. However, at the minute all the links just direct me to the URLs of the most recent random link to be created. If someone could point me in the right direction to fixing this that would be great!

Thanks! Another homework assignment that I can't quite seem to get to work... I've been asked to do the following using javascript: -Create a function named randInt() with one parameter of "size". Declare a variable named "rNum" equal to a random integer between 1 and the value of the size variable. Return the value of the "rNum" varialbe from the function. -Create a function named getQuote() with one parameter anemd "qNum". The function should create an array named mtQuotes with five quotes; there should be no quote for the array index "0". Return the value of the mtQuotes array for the qNum index. - In the div element of "quotes" insert a script with the following commands: Declare a variable named "randValue" which is euqal to a random integer between 1 and 5 (use the randInt() function). Declare a variable named "quoteText" containing the quote whose array index value is equal to randValue. Write the value of quoteText to the web page. Here is what I have...it returns undefined. thanks. Code:
<html>
<head>
<script type="text/javascript">
function randInt(size) {
var rNum=Math.ceil(Math.random()*5);
return(rNum);
}
</script>
<script type="text/javascript">
function getQuote(qNum);
var mtQuotes = new Array();
mtQuotes[0] = "";
mtQuotes[1] = "I smoke in moderation, only one cigar at a time.";
mtQuotes[2] = "Be careful of reading health books, you might die of a misprint.";
mtQuotes[3] = "Man is the only animal that blushes or needs to.";
mtQuotes[4] = "Clothes make the man. Naked people have little or no influence on society.";
mtQuotes[5] = "One of the most striking differences between a cat and a lie is that a cat has only nine lives.";
return mtQuotes[qNum];
</script>
</head>
<body>
<div id="quotes">
<script type="text/javascript">
var randValue=randInt(5);
var quoteText=getQuote(randValue);
document.write(quoteText);
</script>
</div>
Here is the code I am working with, been at it for 3 days now. I am at a loss....cant see why it shouldnt work. window.onload = defineMarquee; var timeID; var marqueeTxt = new Array(); var marqueeOff = true; function defineMarquee(){ var topValue = 0; var allElems = document.getElementsByTagName("*"); for (var i=0; i < allElems.length; i++){ if (allElems[i].className =="marqueTxt") marqueeTxt.push(allElems[i]); } for (i = 0; i < marqueeTxt.length; i++) { if (marqueeTxt[i].getComputedStyle) { topValue = marqueeTxt[i].getPropertyValue("top"); } else if (marqueeTxt[i].currentStyle) { topValue = marqueeTxt[i].currentStyle("top"); } } document.getElementById("startMarquee").onclick = startMarquee; document.getElementById("stopMarquee").onclick = stopMarquee; } function startMarquee(){ if (marqueeOff == true) { timeID = setInterval("moveMarquee()", 50); marqueeOff = false; } } function stopMarquee(){ clearInterval(timeID); marqueeOff = true; } function moveMarquee(){ var topPos = 0; for (i=0; i < marqueeTxt.length; i++){ if (marqueeTxt[i].getComputedStyle) { topPos = parseInt(marqueeTxt[i].getPropertyValue("top")); } else if (marqueeTxt[i].currentStyle) { topPos = parseInt(marqueeTxt[i].currentStyle("top")); } if (topPos < -110) { topPos = 700; } else { topPos -= 1; } marqueeTxt[i].style.top = topPos + "px"; } } 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: Code: <script type="text/javascript">

Any suggestions? Thank you! I'm new to javascript and am not sure why this works in firefox and not chrome. I am trying to create a script that keeps an object fixed horizontally while bing positioned absolute vertically. if I replace the toPP variable in document.getElementById('fire').style.top = toPP; with say '50px' it will move the element down 50 pxs, but how I have it currently it doesn't do anything in chrome Code: <script type="text/javascript" >
window.onscroll = function()
{
if( window.XMLHttpRequest ) {
var x = 0 -document.documentElement.scrollTop;
var toP = String(x);
var toPP = toP + "px";
document.getElementById('fire').style.position = 'fixed';
document.getElementById('fire').style.top = toPP;
}
}
</script>
I need to convert a position:fixed element to position:absolute when the user resize their browser window below 1000px. Right now it does nothing. The element always keeps the fixed positioning even after resizing the window. Here's what I have right now: Code: <!DOCTYPE html>

I'm a student and i missed first Javascript. Could someone please just put me into the right way to make it work, I can't honestly find an answer anywhere. E.g. I have following declaration in the head section of html: <script language="javascript" type="text/javascript" src="java1.js" </script> My aim is to initialize a string variable firstname in java.js to be displayed on a page. I declare it in java.js as: var firstname="Tom"; I put document.write statement to the head of html section as: <script language="javascript" type="text/javascript" src="java1.js"> document.write; </script> ....but it doesn't work. Could someone just point me into the right direction, I tried w3c and others but unsuccessfully, it looks like everyone just seamlessly go straight to the coding. hi every one i;m new here and i love to know programming languages and some friends adviced me to start with java script then php , and i guess i'm at the right place can you please tell how to start and where to begain i'm really don't know anything about programming
Hi guys I'm new to the forums here. I want to learn how to use Javascript and AJAX along with jquery or prototype to develop a dynamic website. For example, I like how www.dropbox.com works. Everything has a transition, and you can drag and drop things around which is what I like. Ultimately I hope to be able to develop a dynamic website with social networking elements. I know my goals are lofty, but where should I get started and what should I learn. I have some cursory programming experience with visual basic, fortran and html. Any particular books that would help me learn. Ideally a book would have some programming "challenges" or small projects that would give me some experience. Thanks Ok so i want to code something like this http://i45.tinypic.com/29y10s1.png I want it to where the user just clicks on one of the buttons and it changes to the thing. But then i want to be where if the user doesn't click anything then it just changes by itself. so like on a timer. Can anyone give me some references that might help me get started with coding this. I have no clue where tos tart. |
