JavaScript - Mouse Speed Onmouseover/out
I have a piece of raw code. I want to make some images greater/smaller onmouseover/onmouseout, in a graduate mode, on using some independent setTimeout objects which are to be started/clear . It works ok if the mouse goes up and down at a reasonable speed. But if the movement is fast, the onmouseout looks to fail in firing (and some images remain on their bigger stage), which is somehow weird. Where could be the mistake? What did I make wrong (except that I might have had done that with Flash)? Any thoughts?
You have in the attachment (see test.zip) the full example, with the used images, as well. Code: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Similar Tutorialsfor example i have: a picture of a man sitting down a gif of him going from the sitting position to the standing position and picture of him standing i want the man to sit when the page is loaded, go to the standing animation onMouseOver, and when the animation is complete, stop the animation by going to the standing picture i have heard of two ways to do this but i dont know the best way, or if there is a third alternative with PHP or another language i could make a timer of the same period of time it takes for the standing gif to complete. i havent done any testing but i would suspect that there would be a bug with this method. some older computers load slower, and the gif may finish its animation before the timer is complete, or the timer may complete before the gif has finished its animation. this might cause gif to start a new cycle before the browser changes pictures, or the browser might change pictures before the man is finished standing. if you know for a fact that this will not happen, or if its occurrence is extremely rare, please alleviate my fears the second option is to break the gif down with some piece of software into jpegs and make many timers to reassemble the animation. this method was not suggested to me, i came up with it myself, so i dont trust that this is the best way to do things properly anyone who has ever done this sort of rollover animation in any language, your input would be greatly appreciated I've got to have a typo somewhere, but i can't seem to find it. I need a new pair of eyes to point it out for me. background: trying to code a mouseover link for a nav bar. everything is working( hyperlink, normal image shows up) but when i mouse over the image swap doesn't happen. I have 2 parts of code. 1st preloads images and does the swap function. loads in <head> See below: Code: <SCRIPT language="javascript" type="text/javascript">
if (document.images)
{
/* preload images */
var subcontractorsOn = new Image ();
subcontractorsOn.scr = "subcontractorsOn.gif";
var subcontractorsOff = new Image ();
subcontractorsOff.scr = "subcontractorsOff.gif";
}
function mouseOn (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "On.scr");
}
function mouseOff (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "Off.scr");
}
</SCRIPT>
2nd just calls the functions to preform the swap. this is in the <body> see code below Code:
<a href="subcontractors.htm" onMouseOut="mouseOn('subcontractors')"
onMouseOver="mouseOff('subcontractors')">
<img src="subcontractorsOff.gif" height="40" width="133" name="subcontractors" id="subcontractors" border="0" alt="subcontractors"></a>
any insight would be great. regards, Fatmann66 Hello, I'm working on a rotator and I'm needing to slow it down. I think I would use var speed right? How would I use it in this script? <script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script> <script type="text/javascript"> $(document).ready(function() { $('.slideshow').cycle({ fx: 'fade' }); }); </script> Hello. I have a problem. I use google map to show some points. I have to show all points for some region, and number of points gets to 4.000. So it takes some minutes to show all points. I use gif image-> size: 400 bytes I found http://fundrace.huffingtonpost.com/ and it takes only couple of seconds to load more 1000 markes. Does someone know how to resolve this? Thanks I have this horizontal news ticker which works just perfect in ie7 regarding to speed, but when looking at the same page in ie8 the speed is very slow... Has anybody else encountered this, and if yes... How do I solve this? Code: initialize: function(element, options) {
this.setOptions({
marHeight: 18,
marWidth: 565,
steps: 20,
speed: 20,
direction: 'left',
pauseOnOver: true,
pauseOnContainerOver: true
}, options);
this.timer = null;
this.textElement = null;
this.mooqueeElement = element;
this.constructMooquee();
}
Thanks in advance :-) Hi all, I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this Code: <div id="myDiv"></div>
...
function test() {
for (i=0 i<100; i++) {
var obj = document.create("div");
// do stuff to style div and set content
document.getElementById("myDiv").appendChild(obj);
}
// DO SOMETHING WITH ONE OF THESE DIVS
}
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access? I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times. The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch. Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away. Any information much appreciated, I hope I have been clear enough. I'm using IE7 and so are the testers. Thanks, Dale I have made myself an HTML Menu which is located on top of my current Flash object. I have a question whether it really is not possible to get the same effect as 'text' has on the original "Flash Menu" EX: www.moebelarkitekten.dk and get the same effect over at my new HTML menu (Coded with Jquery) EX: http://www.richyjassal.co.uk/moebelar/ Right now it is almost the same effect, but only: OnMouseOver align text to Right OnMouseOut text to align left A guide, or other? i need script will detect connection speed and redirect to a page:
i have pasted below java script code. please check write or wrong <script language = "JavaScript" type="text/javascript"> // Remove down to "ConnectionSpeed Detection section" if you don't want to use cookies // If you drop a cookie it can be picked up on return by php or something else function setCookie(name, value, expire) { document.cookie = name + "=" + escape(value) + ((expire == null ?

In the home page (index.html) i have a flash intro. The first time a user sees the website, the intro should play. Once he goes to another page (about_us or contact_us) and comes back to the home page, it should show a different swf (the version without the intro) - i have created two swf files. I need to know how to change them when the user has already seen the intro or was in the home page before. When i googled, i found something on cookies. I have no clue on how to set them and change the swf file. Would be great if someone has already done this or point me to a tutorial. i need java script. please help!!!!!!! Hello Experts, I did a website & I am having trouble wit it. In IE8, FF& Chrome, the site works perfectly. But in IE7, the site slows down very much that even the link hover effect doesn't show properly. I believe its some kind of javascript or Ajax request which is causing such delay. Can you guys please help me sort this out.... Here is the site with functionality... http://tinyurl.com/3qkunvy Here is the site without functionality but just the gallery is integrated... http://tinyurl.com/439ejhk The speed was even better before the Ajax is applied for contents. Any solutions/fixes please... was wondering if it made sense to optimize the comparison order inside an if() statement if one of the comparison targets is a function call eg: Code: var a = true,
b = function() {return false;};
if (b() || a) {...}
if (a || b()) {...}
would the second statement run faster because it would theoretically never need to call b() in this situation? can the eval order be relied on? does this depend on the js engine/internal optimizations? thanks, Leon Hello good coders! Thanks to the wonderful script provided by coothead he http://www.codingforums.com/showthread.php?t=87036 I was wondering how I could adjust the transition/fade speed between the images in the script? I tried a couple of different ways, but I couldn't get it working. Does anyone know how I can adjust this in a cross-browser compatible way?

Alright I know about the problems IE has, but I'm testing out an id that is titled "slideRecord1" and trying to move it. The functions work with Firefox for the onmouseover and onmouseout attributes. But IE doesn't support that. So I'm trying to do it manually in the Javascript, but it's still not reading it. Any help? Code: /* <![CDATA[ */
document.getElementById('slideRecord1').onmouseover = function(){slideRecord(1);}
function slideRecord(disc)
{
var record = "disc"+disc;
var y = 20;
document.getElementById(record).style.top = y + 'px';
}
function unSlideRecord(disc)
{
record = "disc"+disc;
var y = 0;
document.getElementById(record).style.top = y + 'px';
}

Hey i need some help with the mouseover commands i cant find the one that will allow me to mouse over a button and a menu with subcategories
Hey guys I am currently trying to set up a set of <li>'s to act as links just so: Code: <li onmouseover="location='http://www.google.com'">Text</li> Obviously this works fine, however what I need it to do is load in an iframe rather than reloading the browser. So the question is, what code do I need to get target data in to the js? Thanks! I have a dropdown list working, but I want the dropdown list to be initiated when the mouse goes over the first link in the list. Once it is visible, I want it to remain visible so long as the mouse is over any of the links. Right now I have it working for being visible only when the mouse is over the first link, but it does not remain visible moving the mouse over the first link, down the drop down menu. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 TRANSITIONAL//EN"> <html> <head> <style type="text/css"> div.ff { border:2px solid white; display:none; width:200px; background-color:red; margin-top:5px; } a { width: 200px; text-align:center; background-color:red; color:white; font-size:16px; display:block; } </style> <script type="text/javascript"> function ab(a) { document.getElementById(a).style.display="block"; document.getElementById(a).parentNode.onmouseover="ab(a)"; document.getElementById(a).parentNode.onmouseout="ab1(a)"; } function ab1(a) { document.getElementById(a).style.display="none"; } </script> </head> <body style="background-color:black;"> <div> <a href="kkjklj.com" onmouseover="ab('dg')" onmouseout="ab1('dg')">kjlj</a> <div id="dg" class="ff"> <a href="kjlj.com">lkjefee</a> <a href="ehfueh.com">fheufheuih</a> </div> </div> </body> </html> |
