JavaScript - Help With Moving An Image Across The Screen! (js)
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';
if ((x+interval < dest_x) && (y+interval < dest_y)) {
//Keep on calling this function every 100 microsecond
// till the target location is reached
window.setTimeout('moveImage()',30);
if (x == dest_x) && (y == dest_y) {
NewDest();
}
}
}
</script>
<body onload="Start()">
<div id="ufo" class="movable">
<img src="Mouse.jpg" alt="mouse" WIDTH = 30/>
</div>
</body>
</html>
Similar TutorialsSo this is my first thread and I am a noob at javascript so please forgive obvious mistakes. I am try to make images float across the screen horizontally. Ideally I would like them to come from both sides and be at different y positions. The problem I am having is that I can only seem to get one to move at a time. Another problem is that when they move off to the right of the screen it expands the viewable size of the site. So here's what I've come up with thus far.

Any help is greatly appreciated. Thanks 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 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 : Hi 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. My code is: Code: <html>
<head>
<script type='text/javascript'>
winx=220
winy=176
self.resizeTo(winx,winy);
</script>
<img id="default"
style="z-index: 0;left: 0; position: absolute; top: 0px"
height=32 width=32 align=baseline border=0 hspace=0 src='save.gif'></p>
<script type="text/javascript">
document.getElementById("default".style.top = '0px';
document.getElementById("default".style.left = '0px';
</script>
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, 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 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>

Hi Guys, I would like to be able to change my webpage background image according to the screen resolution the user uses so: if screen resolution is greater than or equals to 1200*600 then background = mybackground.jpg no-repeat else background = #000000 THANKS A MILLION! Hi Everyone, I have just inherited a website which has a javascript menu tab and picture fader on the home page. This moves through 6 states changing a menu tab and main picture beneath to make it look like you're flicking through the menu yourself. This works perfectly, apart from the fact that every time the picture changes the page flicks back to the top. Very annoying if you have scrolled down are reading things at the bottom of the page!! The page uses jquery-1.2.3.pack.js. I am a PHP man just starting to learn Javascript and don't understand why it is doing this, can anyone help ??? The Relevant Code is: Code: <script>

The code 'works' as in there are no issues in its functionality, I just want it work in a better way. Any help or ideas would be greatly appreciated. Hi, I am an asp.net developer and I wanted to display user popup (kind of) which freezes the screen so that user won't click anything else on the screen. There are some predefined controls in asp.net, but I wanted do this using Javascript. Where can I find a sample with code? Thanks Dear Experts, I am very new for javascript so I am not even sure it is possible or not. The situation is like this, I have a page, which is actually a photo gallery with a table having 3 rows. First row shows the full screen size pic. Second row displays the Caption of that image and third row shows thumbnail view of six different images and the previous and next button. this is the sample layout: <table> <tr> <td colspan=8> Full size image will be shown in this cell </td> </tr> <tr> <td colspan=8> Caption of the image will be displayed here </td> </tr> <tr> <td>Previous Button</td> <td>Pic1 thumbnail view</td><td>Pic2 thumbnail view</td><td>Pic3 thumbnail view</td> <td>Pic4 thumbnail view</td><td>Pic5 thumbnail view</td><td>Pic6 thumbnail view</td> <td>Next Button</td> </td> </tr> My requirement is whenever the user click on the thumbnail view, which is in the 3rd row, the corresponding full screen size pic should open in 1st row of the table. As my photo gallery should be having more than 6 pics, lets take 20 pics, I want to show only 6 thumbnails in 3rd row at a time. Whenever user press "Next" button the 3rd row having 6 thumbnails should show other 6 thumbnails and previous button should show previous 6 thumbnails. I have a guess that it can be done using arrays, but how????? I have no idea. So please if you have any guesses it will be nice if you can post the entire code here as I will not be in a position to work on the hints given by you. Thanks in advance. Charles 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!

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>

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 am trying to find some examples of something I know I have seen in the past, but I am unable to put together a search that is coming up with anything. What I have is a div of content that I need to always be visible on the screen. The page needs to be scrolled to read through it all so I need a way for the div to move down the page as I scroll. Can anyone point me in the right direction? |
