JavaScript - Moving Cell With Arrow Buttons
Hello. I want to move something with the arrow keys, but some aprt of script is incorrect and it's not working
Code: </style>
<script type="text/javascript">
function setup() {
row=0;
col=0;
imageSnake(row,col);
}
</script>
</head>
<body onload="setup()" onkeydown="handleKey(event)">
<center>
<script type="text/JavaScript">
document.write('<table border="1" cellspacing="0" cellpadding="10">')
var count =0
for (var row=0; row<20; row++) {
document.write('<tr>');
for (var col=0; col<20; col++) {
document.write('<td style="border:0"; id="count++";>');
document.write('</td>');
}
document.write('</tr>');
}
function handleKey(e) {
if (e.type == 'keydown' && (e.keyCode == 27 || (e.keyCode >= 37 && e.keyCode <= 40))) {
switch(e.keyCode) {
case 37:
dC = -1;
dR = 0;
break;
}
emptyCell(row,col);
function emptyCell
var id = 'r' + r + 'c' + c;
var cell = document.getElementById(id);
if (cell) cell.innerHTML='';
}
row += dR
col += dC
function insertImage(r,c) {
var id = 'r' + r + 'c' + c;
var cell = document.getElementById(id);
var color = cell.className;
if (color != 'white') {
var image = 'img.gif';
}else{
var image = 'img2.gif';
}
cell.innerHTML = '<img src="" + image + alt="" + color + 'image' />';
}
</script>
Thank you for any noticed error. Similar TutorialsI have three buttons on a typical page (sample page: http://jimoberst.com/paintings/p18.html). One goes to the previous page, one to the next, and one up a level. Can I link these buttons to 3 arrow keys to simplify navigation for the user? I thought this would be a common task, but I cannot find any canned code on the web to do it. I can code simple html, but don't know javascript. Thanks!
I want to use an onkeydown() on my web site and the web site to know which key I pressed. Specifically know I pressed the arrow keys and store which key was pressed in a variable. any help? must work on all browsers. I've seen websites that have things like feedback and an arrow facing up that either take you to the top of the page or opens a form to give your feedback.
Hey! I searched a while on the web for this but i didn't find a solution that really worked. So is there a way how i can prevent IE9 from scrolling when i use the arrow keys? Disable Arrow Keys I am creating an online flash gaming site, Aaron's Game Zone: http://azzaboi.weebly.com Some of the games on it use the arrow keys, however IE also uses them to scroll the page. I am learning JavaScript and am trying to write some script to pervent the page scrolling up and down while playing a game. For example... Guardian Rock uses the arrow keys to slide around, at the same time the page scrolls. http://azzaboi.weebly.com/guardianrock.html Here is the script I've tried to write to pervent the scrolling: Code: <script type="text/javascript">
function KeyPressHappened(e){
if (!e) e=window.event;
var key=e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
if(key == 37 || key == 38 || key == 39 || key == 40)
{
e.preventDefault();
return false;
}
return true;
}
document.onkeypress = KeyPressHappened;
</script>
There's a bug in it or it's not correct, no error message given, could anyone point out the mistake please? hi everybody; i'm using this code to trigger functions with left and right arrow keys.. but they work even if the arrow keys pressed in input boxes.. is there any way to prevent this code to work when user presses the arrow keys in input boxes? Code: document.onkeydown = function(evt) {
evt = evt || window.event;
switch (evt.keyCode) {
case 37:
geri();
gostergeyaz();
break;
case 39:
ileri();
gostergeyaz();
break;
}
};
I have a search box on my website, that gets users from my database using php. And uses Javascript to display suggestions as the users type. What I'd like to be able to is to use the arrows to toggle down through the different suggestions. Any ideas how I would go about doing this? Here's the javascript part of the code: Code: function createObject() {
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}
var http = createObject();
/* -------------------------- */
/* SEARCH */
/* -------------------------- */
function autosuggest() {
q = document.getElementById('search-q').value;
// Set te random number to add to URL request
nocache = Math.random();
http.open('get', 'lib/search.php?q='+q+'&nocache = '+nocache);
http.onreadystatechange = autosuggestReply;
http.send(null);
}
function autosuggestReply() {
if(http.readyState == 4){
var response = http.responseText;
e = document.getElementById('results');
if(response!=""){
e.innerHTML=response;
e.style.display="block";
} else {
e.style.display="none";
}
}
}
Hi All, I have a javascript scrollbar in the middle of the webpage, with two images as arrow at both end. Onclick of up and down arrow images the inside content moves up and down respectively. All works fine. What I need is, when I scroll down the down arrow should be disabled or invisible (as there is nothing to scrolldown) and same way when the content is at the top, the up arrow should be disabled or invisible. Please help...

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. 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 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. 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 ! 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. 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 |
