JavaScript - Help. Moving Image
Hello,
I'm newbie in javascript, but i want to make an moving image. In time it should change to other image with other button. Also it could be changed by user. The change should be dynamic like moving from left to right. ^^ Any advices, tutorial links or smthing.. Thx Similar TutorialsHi there folks. I am a bit stuck with a little code. I am making a online yearbook entry and I wanted an image of myself animate/move from the top left hand to the bottom right of the screen. I also wanted to allow people reading it the option to change bg colour and text size - but I have managed to do those. The difficulty I am having is with moving the image, could anybody suggest any simple codes because I am new to this and don't want my head spinning before I go any further! Any help is greatly appreciated. Hi, I'm noob , but i have nice idea i want to do it but i can't .. i tried many ways to do it .. but didn't work any of them .. the idea is move the foot to room no.1 .. but i want to see the foot moving on the red line to the room like this pic : Hello, I am trying to move an image down 20px each time the button is clicked, but I can only get it to move down once. I see what I am doing wrong, but I'm not sure how to fix it. I don't know how to store the updated position of the image in a variable. Code: <center>
<input type="button" value="Click" onClick="moveDown()"/>
</center>
<img id="Ball" src="ball.jpg" style="position:absolute; top:100; left:100;"/>
<script language="JavaScript">
var Image = document.getElementById("Ball");
var Position = 100;
function moveDown()
{
Image.style.top = Position + 20
}
</script>
Thanks, Celia Hey guys, I was trying to make a Javascript game that moves an image across the screen randomly. Instead of executing properly, it just shows the image's starting point, and stops. No movement. Is there anyway I could fix this? Thanks, Fizz. Code: <html>
<head>
<title>Image Mover</title>
<style>
DIV.movable { position:absolute; }
</style>
</head>
<script language="javascript">
function Start() {
var x = 5; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = Math.floor(Math.random()*650); //Ending Location - left
var dest_y = 500; //Ending Location - top
var interval = 10; //Move 10px every initialization
moveImage();
}
function NewDest() {
var x = 5; //Starting Location - left
var y = 5; //Starting Location - top
var dest_x = Math.floor(Math.random()*650); //Ending Location - left
var dest_y = 500; //Ending Location - top
var interval = 10; //Move 10px every initialization
moveImage();
}
function moveImage() {
//Keep on moving the image till the target is achieved
if(x < dest_x) x = x + interval;
if(y < dest_y) y = y + interval;
//Move the image to the new location
document.getElementById("ufo").style.top = y+'px';
document.getElementById("ufo").style.left = x+'px';

winx=220
winy=176
self.resizeTo(winx,winy);
</script>
<img id="default"

The image shows up, but it doesn't move. I can't seem to find out what I'm doing wrong. Edit: Finally spotted it, I was missing a ")" ._. Hello all! I am fairly experienced in HTML but javascript I am useless with. My website can be found here; http://mgwalker.site90.com/index.html If you would be as kind as to load it in Chrome and in firefox, in firefox the changing image pops up on the top right of the screen. In Chrome it is centered in the div, as it should be... Please help I have no idea why this would happen! I've put together a couple of scripts, in order that I can make an image move left or right on the x-axis, depending on the LR (left/right) read-out from the accelerometer of an iPhone. However, it's not working at the moment, so could anyone possibly see what I've missed out - I've worked on it that long, that I think I'm missing something obvious!! THANKS!! Code: <!doctype html>

This is my code. Now i have problems with the eraseImage and drawImage functions. They just don't work. Any help will be appreciated. Thank you hi all, I want to be able to move an image from a left or right when tilting my ipad. when tilted the the right the image moves to the right according to the angel tilted and do the same to the other direction. the image is doubled (or more) the size of the stage (1024x768). I can't use Flash for obvious reasons so looking at other options. thanks Code: function move_user_img(str) {
var step = 25;
// change this to different step value

What is wrong with my code? I am trying to move a div and it wont work at all. Also my little <a> fix is really sloppy. Could I have some help with how I should fix that too? Thanks! Code: <html>
<head>
<script type="text/javascript">
var obj = document.getElementById("object");
var x = parseInt(obj.style.left);
var y = parseInt(obj.style.top);
function right(){
obj.style.left = "" + (x + 1) + "";
}
function left(){
}
</script>
</head>
<body>
<a href="" onclick="right();">
<div id="container" style="position:absolute; top:100px; left:50%; margin-left:-400px; width:800px; height:600px; border:3px solid #808080;">

I'm trying to create something like: http://www.deliciouslysortedibiza.com/ But I want the links to move like it does in there. Does anyone know the easiest way I could achieve this? Since I'm fairly new to Javascript and all. Thanks ! Hello everyone. I am trying to make a flag with css and then move it with javascript. Code: <html>
<head>
<title>Flag</title>
<link rel="stylesheet" type="text/css" href="flag3.css" />
<script language="javascript">
Hmove=-100;
function moveObjRight(obj)
{
obj.style.left=Hmove;
Hmove+=4;
if(Hmove<900)
window.setTimeout("moveObjRight(" +obj.id+ ");", 0);
}
</script>
</head>
<body>

This is my code. The image is moving to the right, but i want it bounce from side-to-side in the browser window. Any help will be appreciated. Thank you. I already looked at this http://codingforums.com/showthread.p...ht=moving+text thread and I know it's similar. I just don't know what I am doing wrong. My css puts the text where it needs to go, then the script is supposed to alter it's pixel position and so it should move, right? Code: <html>
<head>
<style>
item1 {position: absolute; left:20px; top:280px;}
item2 {position: absolute; right:20px; top:280px;}
</style>
</head>
<body>
<item1 id="item1" >item1</item1>
<item2 id="item2" >item2</item2>
<script type="text/javascript">
var i=0; var j=0;
var obj1=document.getElementById(item1);
var obj2=document.getElementById(item2);
obj1.style.visibility="visible";
obj2.style.visibility="visible";
//if (typeof obj1.style.left!="undefined" && obj2.style.right!="undefined")
//{
//loop from ParseInt to coordinates in center of screen
for (i=0;i<100;i++)
{
obj1.style.left=parseInt(obj.style.left) + i + "px";
document.write("<item1 id="item1">item1</item1>");
document.close();
}
//for (j=0;j<100;j++)
// {
// obj2.style.right=parseInt(obj2.style.right) + j + "px";
// document.write("<item2 id="item2" >item2</item2>");
// }
alert(i);
//}
</script>
</body>

Am I anywhere close? I am trying this on IE6 (I only have Windows 2000) and on Firefox 3.5.3. Hello. I am getting to learn JavaScript, and as for my first personal project, I would like to have a page with some text on it and when the user scrolls, a div containing a picture will move with the user when they scroll. I have found a solution, however, I do not like it. Code: <html>
<head runat="server">
<title>Test</title>
<link type="text/css" href="Main.css" rel="Stylesheet" />
</head>
<body class="mainbackground">
<div id="group">
<div id="sizer" class="sizeholder"></div>
<div id="image" class="image"></div>
</div>
<form id="form1" runat="server">
<div>
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
</div>
</form>
<script type="text/javascript" >
window.onload = function () {
onscroll = function () {
var scrollevel = document.body.scrollTop;
if (scrollevel == 0) {
if (window.pageYOffset)
scrollevel = window.pageYOffset;
else
scrollevel = (document.body.parentElement) ? document.body.parentElement.scrollTop : 0;
}
scrollevel = scrollevel + 250;
document.getElementById("sizer").style.height = scrollevel + 'px';
}
}
</script>
</body>
</html>
As you can see, it works by getting the scroll position and adding 250, to a height property-element above the image div. I have tried to use document.getElementById("image").style.top = scrollevel + 'px', but it does not work. Any ideas??? <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=utf-8' /> <meta http-equiv='Content-Script-Type' content='text/javascript'> <script type = 'text/javascript'> function unselectall(form) { var i=0; for(i=0;i<=15;i++) { tdname = 'invbox'+i; if (document.getElementById && document.getElementById(tdname).style) { document.getElementById(tdname).style.borderColor = '#000000'; form.selected.value = 0; } else { i=20; } } } function selectthis(form, pos) { unselectall(form); var tdname = 'inventory'; document.getElementById(tdname).style.borderColor = '#ffff00'; form.selected.value = form.position1.value; } </script> </head> <body> <form id='inventorytable' method='post' action='addflowerlight.php'> <table id='inventory' border=1> <tr> <td id = 'invbox1' ><img src = 'images/Lights/6inv.jpg' onclick="selectthis('inventorytable', 1);"><input type = 'text' id = 'position1' value='6'></td></tr></table> <input type ='text' id='selected'> <input type ='submit' value='Equip Light'> </form> </body> </html> What am I doing wrong? The onclick wont trigger. I have a blog with a two-column setup... a sidebar and a main section for posting articles, but encapsulated in a div wrap. I am creating a mobile site and want to: 1) remove/hide the sidebar 2) move the main section to the center for easy reading My issue is that I have tried CSS without success in accomplishing BOTH tasks. I easily can hide the sidebar using various methods, but the main section will not move to the center of the wrap, presumably because the sidebar is still there but not visible. So I went the JavaScript route instead with the following: Code: <script type="text/javascript">
<!--
if (screen.width <= 699) {
var wrap = document.getElementById('wrap');
var sidebar = document.getElementById('sidebar');
wrap.removeChild(sidebar);
wrap.style.background = "inherit";
}
-->
</script>
Now my questions is... since the element is now removed, how do I move the main section to the center? I tried grabbing the main section with its id and floating it left (just to play around and see if it would move) and that didn't do anything. Any help would be appreciated. Hi All I am currently working on a site using Lightbox 2.04 and all i would like to do is make a slight alteration to it's basic function and that is: Move the Cation and close button to the top of the display rather than the bottom. This however appears to be proving a little tricky, i have searched the net to no avail and pretty much moved everything around in the .js file and have even had an open post on Huddletogether for the last few weeks but to no avail. Can anyone help. Please!!! Thanks in advance. Hi Guys, seen some pages who give alerts or Warnings mentioning that i'm moving away from my webpage. Best example is hotmail when you are on the compose mail screen and when click another link it is asking for confirmation. Can you one please shed some light on how to do this. Your help is greatly appreciated. Cheers Dileep |
