JavaScript - Onkeydown Delay
Hello All,
This is my first post here, so hopefully I don't make to big an *** out of myself. Anyway, I am working on a small 2D game in javascript, and have character movement bound to the onkeydown event. The problem is, that there is a momentary delay between pressing the key, and then it realizing you are still holding it down. So it's Move->stop->Move smoothly You can see what I'm talking about here http://www.digitalswordsmen.com/at/townmap.cfm I know that the delay is happening at the operating system level (you see the same kind of delay if you open up notepad and hold down a letter key, first letter appears instantly, then a short delay before continuing). I was wondering if anyone has a possible solution though, or someway I could smooth out that delay. Also, the walking animations only seem to work in firefox. I guess IE doesn't play animated gifs while the onkeydown even is being fired. Not sure if there is a fix for that, other than animating the individual frames with JS, but that would be pretty laggy I think. Anyway, any input is appreciated. You can see all the code by of course just viewing source, its still fairly simple at this point. Thanks in advance. Similar TutorialsI want to code a script that when you press the right arrow key, it goes to a page. any ideas? I was wondering if anyone could shed some light on this little problem. Code: function lostfocus(current,productNum,e)
{
var keycode;
if (window.event)
{
keycode = window.event.keyCode;
}
else if (e)
{
keycode = e.which;
}
if(keycode == 0)
{
if(current == ($("#itemCount"+productNum).val()-1))
{
newItem(productNum);
}
}
else
{
alert(keycode);
}
}
Works great in FireFox, but not in IE7 - it doesn't even get to the else alert statement. This is how it is called.. onkeypress='lostfocus($current,$productNum,event)' And that is inside of a input type=text element. And help would be greatly appreciated. Just like the title says. What would make a block of code that runs an "onkeydown" work perfectly fine, but when changed to "onkeyup" it fails. I could post code, but I dont even think it would matter? onkeypress also fails.
This is an example piece of code which I wish to add to an onkeydown event: Code: function keyListen(param1,param2,e) {
// keycode for ie
if(window.event) {
e = window.event;
var keycode = e.keyCode;
}
// keycode for firefox, safari and opera
else {
var keycode = e.which;
}
// if right arrow key was pressed execute a function
if(keycode == '39') {
someFunction(param1,param2);
}
}
Then somewhere else in my code I dynamically add the function to an onkeydown event like so: Code: document.onkeydown = function() { keyListen(param1,param2,event) };
This works great in Internet Explorer, Opera, Safari and Google Chrome but not Firefox. Firefox keeps reporting that event is not defined, is there a way around this problem? I have also tried this: Code: document.onkeydown = function() { keyListen(param1,param2) };
I excluded the event, but still the same outcome, works well in all browsers apart from Firefox. Please help me, thankyou. I am trying to assign the left and right arrows, but I cannot get the code to work. It would be great to get some help--I am a newbie to coding. <html> <head> <script language="javascript" type="text/javascript"> document.onkeydown=function(e) { var thelink if (e.keyCode==37) thelink='prevlink' else if (e.keyCode==39) thelink='nextlink' else return document.location.href=document.getElementById(thelink).href} </script> </head> <body> <a href="#" onkeydown="return previous(this)" id="prevlink">PREVIOUS</a><br /> <br /> <a href="#" onkeydown="return next(this)" id="nextlink">NEXT</a> </body> </html> Hi I am creating an animation based on Sam Dunn's tutorial 'Animate Curtains Opening with jQuery' ( http://buildinternet.com/2009/07/ani...g-with-jquery/ ). What i need to do is create a 2 second delay in the curtains opening in order to give enough time for an iframe, thats behind the curtains, to load it's content.

Hello how can I add a time delay to a function, so that the called function will execute only after a certain length of time. For example if I want a div to go 'hidden', 3 seconds after hovering off of a second div? Here is the script code I'm wanting to add the delay to: Code: <script>
function show(id) {
document.getElementById(id).style.visibility = "visible";
}
function hide(id) {
document.getElementById(id).style.visibility = "hidden";
}
</script>
and Code: <div id="div1" onmouseover="show('div2'); fade_in('div2', 2);" onmouseout="fade_out('div2', 2); hide('div2');">
The reason I need this delay is so the fadeout function (which also executes after hovering off the second div completely finishes the fadeout before the hidden function executes. Hi all. The below script is from suckerfish. Can anyone help me include a 'one sec delay' to keep the menu open onmouseout. First menu often closes too fast before I get a chance to move onto submenu. I've tried everything with setTimeout BUT I just can't get it right. Nothing I do works. Can somebody PLEASE show me so I can kick myself. LT Code: <script type="text/javascript"><!--//--><![CDATA[//><!--

var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {

}
sfEls[i].onmouseout=function(){
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
}
}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);

Hi,there, my following script generates random numbers and if random number==1 the background color of textbox="red"; so far it works fine.. What I m tring to do is to tell my script to write amessage in the same textbox after 5 seconds so ı need a delay function.. thanks for help PHP Code: <body bgcolor="pink"> <script> stopx=setInterval("gox()",500); function gox() { var box1=document.getElementById("box1"); var box2=document.getElementById("box2"); box1.value=Math.floor(Math.random()*5); if(box1.value==1) box2.style.backgroundColor="red"; ////////////// // I need a delay function here; // ////////// //???// if(delay==5) box2.value=" 5 seconds passed ,now I will give another message"; } </script> <input type="text" id="box1" style="position:absolute;top:50px;left:20px;width:40px;height:20px;"> <input type="text" id="box2" style="position:absolute;top:50px;left:200px;width:200px;height:50px;"> <input type="button" value="try again" onclick="location.reload()" style="position:absolute;top:250px;left:20px;width:60px;height:50px;"> I would like an image to be the button for a form to be submitted, but a sound is to play onclick for 3 seconds before the submit happens. It sounds easy, with a setTimeout delay, but I can't get it to wait: Code: <script type="text/javascript">
function delay(){
mySoundObj1.TGotoAndPlay('/piano','start');
setTimeout('delay2()',3000) // piano sound lasts for 3 seconds
}
</script>
<script type="text/javascript">
function delay2(){
// nothing here I guess...
}
</script>
<FORM METHOD="POST" ACTION="do something">
<INPUT type="image" onsubmit="delay();return true;" src="image/image.gif" width="60" height="60" type="submit">
</form>
Can anyone do this? I mean maybe it is not possible? I have an AJAX search bar what searches after each keyup, but id like to make it so it runs the search if theres a certain delay after the keyup so if you search "hello" it doesnt run 5 times, only once (because there wont be a half a second gap between each letter. Sorry if that doesn't make sense >.<, im just curious if 1) thats possible, 2) what i need to look at to get this to work. Thanks I'm creating a new thread just for the sake of getting help from other people and getting help fast. Not sure if other people are or will be facing similar problems as I am but I will post this on the forum for other people's sake... I want to make my drop down box similar to the one seen at http://www.gamewearteamsports.com/ The menu links act as normal links but will drop down to a div box when a person hovers over the link. The box will appear when the person hovers it but SHOULD disappear once the person does not hover over the box anymore. So if the person hovers over another link, the box should disappear. I added a delay timeout to one of my div boxes and the box stays alive for a couple of seconds but then closes back up again even though I'm still hovering over it. Any ideas? My js: Code: <script type="text/javascript">
function drop(which)
{
document.getElementById("drop" + which).style.display = "block";
}
function undrop(which)
{
document.getElementById("drop" + which).style.display = "none";
}
</script>
My menu links code: Code: <ul id="head1" style="width:940px;">
<li><a href="#" onmouseover="drop(1)">Basketball</a></li>
<li><a href="#" onmouseover="drop(2)" onmouseout="undrop(2)">Football</a></li>
<li><a href="#" onmouseover="drop(3)" onmouseout="undrop(3)">Volleyball</a></li>
<li><a href="#" onmouseover="drop(4)" onmouseout="undrop(4)">Soccer</a></li>
<li><a href="#" onmouseover="drop(5)" onmouseout="undrop(5)">Baseball</a></li>
<li><a href="#" onmouseover="drop(6)" onmouseout="undrop(6)">Hockey</a></li>
<li><a href="#" onmouseover="drop(7)" onmouseout="undrop(7)">Training</a></li>
The code I have for the first link: Code: <div id="drop1" onmouseout="setTimeout('undrop(\'1\')', 3000);" style="z-index:3000;">
There's a table with content in it inside the div. There's a </ul> tag that closes out the menu links. Pretty simple, I just want to display a <div> after say 20 seconds or any predefined value. Ideally with jQuery
Hey i need some help delaying this script so it starts 5 seconds after the page loads not instantly. <script> $('#ad_1 > img').each(function(i,e){ rotate($(this),600,4000,i); }); function rotate(elem1,speed,timeout,i){ elem1.animate({'marginLeft':'18px','width':'0px'},speed,function(){ var other; if(elem1.parent().attr('id') == 'ad_1') other = $('#ad_2').children('img').eq(i); else if(elem1.parent().attr('id') == 'ad_2') other = $('#ad_3').children('img').eq(i); else if(elem1.parent().attr('id') == 'ad_3') other = $('#ad_1').children('img').eq(i); other.animate({'marginLeft':'0px','width':'35px'},speed, function(){ var f = function() { rotate(other,speed,timeout,i) }; setTimeout(f,timeout); }); }); } }); </script> Hey all, I have a couple of videos that display on web page. I want one to display 5 seconds after another when someone clicks a link. Now I know of the setTimeout method, but I can't seem to get it to work in this below code.

Hi. I hope someone can help. I am using a 'suckertree horizontal menu'. I am trying to alter the javascript to provide a delay with mouseout (to hide the UL). I am having issues! Here is the original code: Code: ultags[t].parentNode.onmouseout=function(){
this.getElementsByTagName("ul")[0].style.visibility="hidden"
}
Here is the code I am working with: Code: ultags[t].parentNode.onmouseout=function(){
setTimeout("this.getElementsByTagName(\"" + ul + "\")[0].style.visibility=\"" + hidden + "\"", 1500);
}
Any help greatfully recieved! Hello, I am making a coupon for my mobile website that has to have a response within 60 seconds or so (I would like to be able to play with the time too). This code works but I need to delay the countdown running for a for say 15 seconds after tthe page loads so the people who see the page can read it. Also I would like to know if there is a way I can redirect the page if they do not respond within the countdown time that would go back to the mobile site home page. Also If they leave the coupon page and then go back to the coupon page could I make it so the countdown would still be running as if they never left. I am including the code for the coupon. Almost forgot, can the countdown numbers be red and underlined? Thanks in advance P.S. I don't know much javascript (enough to get in trouble) I searched all over for a solution (till my eyes felt like hemeroids) without bugging you about it. <body> <table cellpadding="3" cellspacing="0" style="width: 320px; height: 480px;"> <!-- MSTableType="layout" --> <tr> <td style="height: 480px; width: 320px;" valign="top" class="style1"> <strong class="style3"><span class="style2">Free Gift !
