JavaScript - Timer Is Ok When It's Of A Small Font Size, But Too Slow When It's Larger
OK, so I've written a small timer at http://zeroerror.co.uk/public/cubetimer.php for general purpose timing.
My first is that I cannot find a way to accurately time with the format 00:00.00, as the milliseconds seem to run too slowly. My second is that when the font size is set to a large size (for example, 200px or 300px) the timer runs even more slowly (just over half the speed it should). Is there any way to optimise the timer so it runs at a more accurate speed, or is this just a problem with my browser parsing the Javascript in time? Here's the code: Code: function timeIt()
{
init = 1;
if (countMsL == 9)
{
countMsL = 0;
if (countMsU == 9)
{
countMsU = 0;
if (countSecs == 59)
{
countSecs = 0;
countMins++;
}
else
{
countSecs++
}
}
else
{
countMsU++;
}
}
else
{
countMsL++;
}
displayMsL = countMsL;
displayMsU = countMsU;
if (countSecs < 10)
{
displaySecs = '0' + countSecs;
}
else
{
displaySecs = countSecs;
}
if (countMins < 10)
{
displayMins = '0' + countMins;
}
else
{
displayMins = countMins;
}
readout = displayMins + ':' + displaySecs + '.' + displayMsU + displayMsL;
timerDisplay.innerHTML = readout;
timerActual = setTimeout('timeIt()', 10);
}
Thanks in advance! Similar TutorialsHi, i have this piece of code to change font size in textarea: Code: <script type="text/javascript">
function changemysize(myvalue)
{
var div = document.getElementById("sss");
div.style.fontSize = myvalue + "px";
}
</script>
And this is html: Code: <select> <option onclick="changemysize(10);" selected="selected">10</option> <option onclick="changemysize(30);">30</option> <option onclick="changemysize(60);">60</option> </select> <textarea id="sss" name="sss"></textarea> This works fine in Opera and FireFox, but doesnt work at all in Google Chrome Is there some "special piece of code" i have to add to be compatibile with Chrome (like css and internet explorer ), or...? Any solutions? I have a button (in html) and I want the center of the button to be on the center of the line I'm typing on... I was just putting it inside a span and then using this code to move it down. Code: <span style="position:relative; bottom:-10;"> It worked great! But... once I started allowing my users to change the font sizes the buttons got bigger and they needed to be moved down further... if the font size was +1: Code: <font size="+1"><span style="position:relative; bottom:-10;"> if the font size was +6: Code: <font size="+6"><span style="position:relative; bottom:-27.5;"> So is there a way in javascript to detect the current font size and then adjust the span position based off of that? If I can just get the number of the current font size I can do all the rest of the coding, I just need a way to figure out the current font size and put it in a variable... I was thinking of using something like 1.0em so that it stays the same but then we have a basis of measuring off of but I have no clue.. I'm fairly new to javascript. Thanks! I want to deviate from using css to designate a font size in one place. I have a string with a name. This is stored in a variable called "name." I just re-defined name to include district number. Now, it is name=lastname+', '+district; I am appending this string into the html dom. I want the district portion to appear in a slightly smaller font. How can I do this without having to set up a separate <span>? Or can this be done? Dear All, I need to get JavaScript to change the font size used for a website if Opera is detected. I have been trying this but it hasn't worked: Code: function changeFooter(){
if (navigator.userAgent.indexOf("Opera") >= 0) { // if I alert this line the output is 0
document.getElementById("footer").style.fontSize = '0.5em';
};
};
in the head of the html document (as well as the link to the external JavaScript file): Code: <script type="text/javascript"> changeFooter(); </script> I tried using window.onload = changeFooter(); but still no luck. I used the same principle in a different function to change another css property via getElementById and it works beautifully so I am a bit puzzled. I then realised that I actually need to change the value of the font size in the body tag from 100% to 90% when Opera is detected so I changed the script to this: Code: function changeFooter(){
if (navigator.appName == 'Opera') {
document.write('<link href="styleOpera.css" rel="stylesheet" type="text/css" />');
}
else {
document.write('<link href="style.css" rel="stylesheet" type="text/css" />');
};
};
But it's still not working. I was hoping that I could benefit from your collective wisdom as I am not sure where I am going wrong with this and several hours spent searching the web for answers have been fruitless so far... My knowledge of JavaScript is not very extensive, I haven't studied it in great depth so perhaps I am making some very silly mistakes here. My pseudo code for this exercise is something like this: Code: detect browser
if browser = Opera {
change font-size for body to 90%
}
else {
do nothing
}
alternatively:
detect browser
if browser = Opera {
link to stylesheet1
}
else {
link to stylesheet2
}
Thanks in advance for your help, much appreciated. Kind regards, Cristina Alciati New to JavaScript so PLEASE bear with me. Trying hard to learn. My client specifically asked for a type of menu (scroll over a thumbnail and you see a large photo in the column next to it. And of course the thumbnail is clickable to new page. I am using this Jeremy Keith script: PHP Code: /* This script and many more are available free online at The JavaScript Source!! http://javascript.internet.com Created by: Jeremy Keith / Anonymous | http://www.alistapart.com/articles/imagegallery/ */ function showPic(whichpic) { if (document.getElementById) { document.getElementById('placeholder').src = whichpic.href; if (whichpic.title) { document.getElementById('desc').childNodes[0].nodeValue = whichpic.title; } else { document.getElementById('desc').childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue; } return false; } else { return true; } } var previousToggle=null; function toggleMe(a){ var e=document.getElementById(a); if(!e)return true; if(e.style.display=="none"){ e.style.display="block"; if(previousToggle)previousToggle.style.display="none"; previousToggle=e; } return true; } and it works fine, except that I can't figure out how to make it showpic on mouseover and still go to new URL (basic link to a page) onclick. Here's a link (one of 8)in the body: PHP Code: <a onmouseover="toggleMe('para1'); showPic(this); return false;" href="design.html" title="blah blah blah"> <img src="images/pix_smaller3.jpg" width="70" height="70"></a> It either links to new page with the href="design.html", or swaps in larger pic if I href to the img file, but I can't seem to get BOTH to work. I obviously want the <a> to be to a new page, not the larger img. Shouldn't showPic take care of this? Where is showPic getting its imgs from? I know that this can't be that complicated, but I have been up for 2 nights trying to figure this out. Any help appreciated... I would like to take a series of images and paste them into a final larger image before displaying it to the user. From what I've read there are libraries that use HTMLcanvas that could achieve this but they don't work even with newer versions of IE. I was wondering if there were functions similar to the PHP image editing functions that work with newer versions of IE? Cheers. So i purchased a template from template monster for wordpress. http://www.templatemonster.com/demo/28861.html On the front page when you click on the thumbnail it changes the big image in the middle. I can't figure out how for the life of me to make that image also a link. My main problem is the code below. img_b1.jpg is the full size image and image_1.jpg is the thumbnail image. When you click on the thumbnail it changes the big image in the middle. When I add a clickable href=" to the main image it breaks the whole chain. --------------------------------------------------------------------- <a class="thumb" name="leaf" href="<?php bloginfo('stylesheet_directory'); ?>/images/img_b1.jpg" title="Agrocore"> <img src="<?php bloginfo('stylesheet_directory'); ?>/images/img_1.jpg" alt="Agrocore" /> </a> ------------------------------------------------------------------------ Full code below <div id="thumbs" class="navigation"> <ul class="thumbs noscript"> <li> <a class="thumb" name="leaf" href="<?php bloginfo('stylesheet_directory'); ?>/images/img_b1.jpg" title="Agrocore"> <img src="<?php bloginfo('stylesheet_directory'); ?>/images/img_1.jpg" alt="Agrocore" /> </a> <div class="caption"> <div class="indent1">living set </div> <div class="image-desc">Cool looking but extremely functional and comfortable.

For ex.: I type this text in my form and I saved in database: My home page is http:// www. mypage .com.it And in my site I want to appear like he My home page is http://www.mypage.com.it I am not sure if this is a javascript problem or an html problem. I have posted the code below. The main two areas that I am interested in are 1) the area where the photo is shown in the larger size, and 2) the thumbnails below the larger picture. Right now in the img tag of the first image I have specified a height and width of 450px. The result is that when one hovers the mouse over the thumbnails, all pictures are shown at that size, regardless if they are larger or smaller than 450 x 450 pixels. I am not concerned about the larger images because I will use a script to scale those that someone on this forum was so kind enough to provide me with. The IMPORTANT PART IS HE I am concerned with smaller images. If you remove the height and width portion from the image tag, when you hover the mouse over a picture that's smaller than the others, such as the last one, which is smaller than all the others that are at 450 x 450, the thumbnails "move up". I would like the thumbnails to remain where they are at / for the top area where the photos are displayed to always be the same size, such as 450 x 450 px., and for the smaller pictures to be shown in the center in that area. How can this be done? Note: The entire portion of the stylesheet is not present. Let me know if something important is missing. Code: <html>

Heya guys. My gallery javascript is running very laggy in IE8. Here's an example: www.amex-trading.dk/pizzaovne.php It works fine in chrome, but it's slow when using IE. Any suggestions? I'm trying to slow this image rotator down. I thought I would just change the setInterval part. But it's not working. Quote: $(function() { setInterval( "nextPage()", 7000 ); }); Below is the full script. Am I missing something? Code: // Global variable that controls billboard image rotation
var $rotate = 1;
// Load this script when page loads
$(document).ready(function(){
// Set up a listener so that when anything with a class of 'bbtab'
// is clicked, this function is run.
$('.bbtab').click(function () {
// Turn off autorotation.
$rotate = 0;
// Remove the 'bboard_page_active' class from the visible tab contents.
$('#bboard > ul > li.bboard_page_active').removeClass('bboard_page_active');
// Add the 'bboard_page_active' class to the associated tab contents.
$(this.rel).addClass('bboard_page_active');
return false; //stop the links default action
});
});
function nextPage() {
// id is expected to look like 'bbpage1'.
// We just need the number part at the end so that we can figure out which page is next in the rotation.
var $active_page = $('#bboard > ul > li.bboard_page_active').attr('id') || 'bbpage0';
var $next_page = parseInt($active_page.substring(6)) + 1;
if ($next_page > $('#bboard > ul > li').length) { $next_page = 1; }
if ($rotate == 1) {
// Remove the 'bboard_page_active' class from the active page.
$('#'+$active_page).removeClass('bboard_page_active');
// Add the 'bboard_page_active' class to the next page.
$('#bbpage'+$next_page).addClass('bboard_page_active');
// alert("Active page is " + $active_page + " of " + $total_pages + " and next is " + $next_page);
}
}
$(function() {
setInterval( "nextPage()", 7000 );
});
Hello guys, The title says it all, my javascript hover menu is running perfect in chrome, but really slow in IE. Take a look here - the menu is called "Produkter" Thanks in regard Hey All, I've got the following site that loads great in FF and Chrome (no surprise), but is terribly slow in IE7. It's even quick in IE6, but not 7. Here's the site: http://www.hanshawengines.com/ Now I'm using JQuery in a couple places, but it's by no means nothing crazy. The page is fairly simple. I thought of preloading the main content images, but even after they are loaded in the cycle, the loading time is still slow. Any suggestions on how I could improve this would be greatly appreciated. Thanks. hi guys I am looking at this template: http://www.csstemplatesfree.org/prev...ero/index.html I think the sliding at the top happens way too frequently. How can I slow it down? I think it would be better if the slides change once every 6 seconds. Hi, I am writing a basic app for a client where the customer puts in their order ID and phone number and press submit. When testing it on my PC it worked flawlessly. When I tested on a desktop PC where the screen was a touch screen as well as on Android devices, it seems the browser is a bit slow to respond. If you press each number slowly (waiting 0.5 second per press) it works fine. However if use it normal to fast then the browser does not catch every button press. Any and all advice is appreciated to heklp make this work. Code: <title>DLUX Order alert system</title>

Hi. I am using a mouseover dropdown menu within a rather large table. The script is only 1.6kb so I don't understand why it is going so slow. Mind you this effect is instant in Firefox, Chrome, Safari, Opera. However, in IE 7 it takes about 3-4 seconds. Any advice on how to get this time down in IE 7? Here is a quick sample of the code.
Code: var DDSPEED = 10;
var DDTIMER = 15;
// main function to handle the mouse events //
function ddMenu(id,d){
var h = document.getElementById(id + '-ddheader');
var c = document.getElementById(id + '-ddcontent');
clearInterval(c.timer);
if(d == 1){
clearTimeout(h.timer);
if(c.maxh && c.maxh <= c.offsetHeight){return}
else if(!c.maxh){
c.style.display = 'block';
c.style.height = 'auto';
c.maxh = c.offsetHeight;
c.style.height = '0px';
}
c.timer = setInterval(function(){ddSlide(c,1)},DDTIMER);
}else{
h.timer = setTimeout(function(){ddCollapse(c)},50);
}
}
// collapse the menu //
function ddCollapse(c){
c.timer = setInterval(function(){ddSlide(c,-1)},DDTIMER);
}
// cancel the collapse if a user rolls over the dropdown //
function cancelHide(id){
var h = document.getElementById(id + '-ddheader');
var c = document.getElementById(id + '-ddcontent');
clearTimeout(h.timer);
clearInterval(c.timer);
if(c.offsetHeight < c.maxh){
c.timer = setInterval(function(){ddSlide(c,1)},DDTIMER);
}
}
// incrementally expand/contract the dropdown and change the opacity //
function ddSlide(c,d){
var currh = c.offsetHeight;
var dist;
if(d == 1){
dist = (Math.round((c.maxh - currh) / DDSPEED));
}else{
dist = (Math.round(currh / DDSPEED));
}
if(dist <= 1 && d == 1){
dist = 1;
}
c.style.height = currh + (dist * d) + 'px';
c.style.opacity = currh / c.maxh;
c.style.filter = 'alpha(opacity=' + (currh * 100 / c.maxh) + ')';
if((currh < 2 && d != 1) || (currh > (c.maxh - 2) && d == 1)){
clearInterval(c.timer);
}
}

Hi. I'm using a tooltip javascript from this website: http://sixrevisions.com/tutorials/ja...cript_tooltip/ This is what it looks like when it's working smoothly: http://sandbox.leigeber.com/tooltip/ To fix scrolling issues, I changed (near the lower bottom, under "pos:function(e)"): var u = ie ? event.clientY + document.documentElement.scrollTop : e.pageY; to: var l = ie ? event.clientX + document.documentElement.scrollLeft : e.pageX; I'm using these tooltips for an image map that has 1,000 defined areas. In Firefox, everything works very smoothly. Everything works well and looks smooth/visually pleasing. But in IE, the tooltips are "choppy" and "staticy". They work well when I continuously move my mouse over the image map without stopping. But when I completely stop the cursor on a part of the image map for about 1 full second, and then move my mouse, the tooltip stays where it is even though the mouse has moved. It then takes between 1 - 2 seconds for the tooltip to "catch up" and move to be next to the mouse/cursor - where it is supposed to be. Also, I must note that when I only have a few (like 3 or 4) defined areas for the image map, the tooltip works perfectly fine and smoothly in IE. I'm very new to html and javascript, and so I'm finding myself at a bit of a loss as to why this is occuring. Can anyone offer any help as to how I can make this tooltip go smoothly between defined areas (not sure if that's the correct terminology) of the image map? I'm new to javascript, and so, unsure of which parts could be causing the problems. However, I think it might have to do with the part from pos:function(e) on. If needs be, I'd be happy to post the full javascript code. Code: pos:function(e){
var u = ie ? event.clientY + document.getElementById('bodyid').scrollTop : e.pageY;
var l = ie ? event.clientX + document.documentElement.scrollLeft : e.pageX;
tt.style.top = (u - h) + 'px';
tt.style.left = (l + left) + 'px';
}
