Here's the suggested fiddle - http://jsbin.com/EzUTizuf/1/edit (because of the url navigation change the iframe from Codemirror JSBin goes to a blank page, which is why I didn't add a fiddle before)
I have an anchor navigating to #about.
When the window.location is equal to #about I want to execute a small function corresponding to that specific window location.
This is the last code I tried to do this.
if (window.location.href === "#about") {
$('.about').show();
document.title="About";
alert("About DIV Shows Only From This URL!");
}
If anyone can help it'd be greatly appreciated.
Thanks!

Within the conditional use window.location.hash instead of window.location.href to detect the value of the hash.
The code must also attach an event handler to window.onhashchange to detect when the hash has changed. When the link is clicked jQuery's ready event is not fired since a new page is not being loaded.
$(document).ready(function() {
$('.about').hide();
window.onhashchange = function(){
if(window.location.hash === "#about"){
$(".about").show();
document.title="About";

My HTML Code is :
<!DOCTYPE html>
<html>
<head>
<title>Furry Friends Campaign</title>
<link rel="stylesheet" type="text/css" href="styles/my_style.css">
</head>
<body>
<div id="clickMe">Show me the the Furry Friend of the Day</div>
<div id="picframe">
<img src="images/furry_friend.jpg" alt="Our Furry Friend">
</div>
<script type="text/javascript" src="scripts/jquery-3.1.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$("#clickMe").click(function()
{
$("img").fadeIn(1000);
$("#picframe").slideToggle("slow");
});
});
</script>
</body>
</html>
The accompanying CSS looks like:
#clickMe {
background: #D8B36E;
padding: 20px;
text-align: center;
width: 205px;
display: block;
border: 2px solid #000;
}
#picframe {
background: #D8B36E;
padding: 20px;
width: 205px;
display: none;
border: 2px solid #000;
}
The slideToggle works perfectly, but for some reason, the image doesn't fade in. I've tried setting the duration to longer periods, but that yields the same results. Can someone point out what's wrong with this code? I'm using the latest version of Chrome.
UPDATE: I tried running the example code of the book I was using, which uses jquery-1.6.2.min.js and using that version of jQuery, the code works perfectly. Is this some error on jQuery's part? Or is the new way that things will be done now?
Since jQuery 1.8, fadeIn no longer initially hides the image, so trying to fade in an image which is visible or doesn't have display set to none won't lead to anything.
To fade in, you should hide it first. Initially it's not hidden, since children don't inherit display CSS property, and you have set it to none only on #picframe, the parent of img. Just add $("img").hide(); on ready. This will make it work.
Since it looks like you need to fade it in / out with each click, you could do the following instead of $("img").fadeIn(1000):
if($("img").is(":hidden")) $("img").fadeIn(1000);
else $("img").fadeOut(1000);
Demo below.
#clickMe {
background: #D8B36E;
padding: 20px;
text-align: center;
width: 205px;
display: block;
border: 2px solid #000;
}
#picframe {
background: #D8B36E;
padding: 20px;
width: 205px;
display: none;
border: 2px solid #000;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>

$(document).ready(function() {
//$("img").hide();
$("#clickMe").click(function() {
$("img").fadeIn(1000);
$("#picframe").slideToggle("slow");
});
});
</script>
Somehow, img didn't inherit the display:none in #picframe div. Here's the fix: https://jsfiddle.net/69rLha7e/1/
There is a "timing" consideration while playing with multiple animations a time.
In this CodePen, I used diferent timing for fadeIn, fadeOut and toggleSlide.
And you have to check the display state in order to decide to fade in or out.
$(document).ready(function(){
$("#clickMe").click(function(){
console.log( $("img").css("display") ) ;
if( $("img").css("display")=="inline" ){
$("img").fadeOut(400);
}else{
$("img").fadeIn(800);
}
$("#picframe").slideToggle(400);
});
});
I'm using JQuery UI to toggle the div with effect .toggle('blind', 250).
I have tackled the .stop() method but it was not my goal in toggling the div, because when I want to toggle the div #clContainer even clicking multiple times the other div #ccConatiner can only be toggled next when it is done...
Here's my Code
$(function(){
$("#clContainer").on('click', function(){
$("#ccContainer").toggle('blind', 350);
});
});
#ccContainer,
#clContainer{
margin: 10px;
height: 100px;
width: 100px;

Please help.
You need to set a flag each time your animation starts, and clear it when it finishes. and on each click check for the flag to see if there is an ongoing animation and only animate again if there isn't any ongoing animation.
you can use .promise().done() to set a callback function that will run as soon as all animations on your cube finish, and in this callback clear the animation_ongoing flag:
var animation_ongoing=0;
$(function() {
$("#clContainer").on('click', function() {
if(!animation_ongoing){
animation_ongoing=1;
$("#ccContainer").toggle('blind', 350).promise().done(function(){
animation_ongoing=0;
});
}
});
});
#ccContainer,
#clContainer {
margin: 10px;
height: 100px;
width: 100px;
background-color: #333;
cursor: pointer;
color: #fff;
}
#ccContainer {
display: none;

Im trying to use simple jquery offset() and animate to make my div scroll to the desired div when the user clicks on a link.
Basically, when the user clicks blog it will go to test1
user clicks Contact it will move to test2
user clicks Work it will move to test3.
I implemented some code I had used in a previous project (it had worked before) but the scrolls are not working correctly this time and I really don't know the reason why. I tried searching for a solution but web development has been an on and off thing for me and I don't understand some of the explanations :/ Any help would be appreciated.
EditOne: had to update the html, still not working.

You need to take into account the scrollTop AND offset of the parent div:
JSFiddle: http://jsfiddle.net/TrueBlueAussie/Uafxz/2/
function scrollTo(selector) {
var offset = $(selector).offset();
var $main = $('#main');
$main.animate({
scrollTop: offset.top - ($main.offset().top - $main.scrollTop())
}, "fast");
}
I changed your code to use a single function (passing the target selector). I removed the second id selector as ids are unique and id lookup is the fastest type of lookup anyway (no point slowing it down with a second search).
Note: I had to hide your designHex element for the JSFiddle as it overlapped the first link.
You actually don't target the good element to animate scrollTop :
$('html,body').animate({scrollTop: divPosition.top}, "fast"); // instead of #main_wrapper #main
And as said in comment, your code contains a lot of errors or non-standard notation. For example, you use 3 script tag and 3 function that do the same job. That could be done with only one.
I am trying to build a simple web page for my website using HTML, CSS, JavaScript and JQuery. What I want is to display a slideshow of a few of my images at the top of the page. I just want the pictures to fade out and fade in after one another forever until the user closes the browser. I want each picture to be displayed for a certain amount of time, after which it will fade out and another picture would fade in.
I referred to this as well as this post on SO but couldn't find a solution. I got some idea from this page and tried to develop some code.
The overall layout of the website is as follows:
For this, my index.html page looks like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

The CSS is like this:
body {
background-color: transparent; color: #d0d0d0;

}
#wrapper {

}
#nav>a {

font-weight: bold; border: 1px solid transparent;

}
#nav>a:link {
text-decoration: none; border-color: transparent; background-image: none;
}
#nav>a:visited {
text-decoration: none; border-color: transparent; background-image: none;
}
#nav>a:hover{
text-decoration: none; border-color: #ffa500; background-image: url("/img/1x30_ffa500.gif");
background-repeat: repeat-x; box-shadow: 0px 0px 5px #ffd700;
}
#nav>a:active {

background-image: none;
}
#content {
background-color: #f0f0f0; color: #202020;
padding: 5px; border-radius: 5px;
}
The common.js file is like this:
$(document).ready(function (){
var images = new Array();
images[0] = new Image();
images[0].src = "img/coverpics/sea_link.jpg";
images[1] = new Image();
images[1].src = "img/coverpics/marine_drive.jpg";
images[2] = new Image();
images[2].src = "img/coverpics/backbay.jpg"
banner_rotator("headerlogo", images, 0);
});
And, the banner_rotator.js file is like this:
function banner_rotator(imgid, imgarray, imgpos) {
setInterval(function() {
if (imgpos >= imgarray.length || imgpos == undefined)
imgpos = 0;
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000, "linear");
$("#"+imgid).delay(6500);
$("#"+imgid).fadeOut(500);
// $("#imgposspan").html(imgpos);
imgpos++;
}, 8000);
}
Now, my problem description is as follows:
For the first few seconds the top portion is blank. The image is not showed, even though I am developing and having all the files on my local machine itself.
This first image directly pops up on the screen, instead of fading in.
After this image fades out, the image block vanishes, as if it is set to display: none; for a second. The entire page that follows the image shifts up. Then, the next image fades in and so forth everything runs normal.
Hence, in short, I have problems with the starting of this slideshow. Can anybody please help?
Also please tell me where can I put my code so everybody here can access and see for themselves how it runs?
JSFIDDLE
<img id="headerlogo" />
Don't do that (an image tag with no src attribute)
Put a div that will hold the space (set position:relative with width & height in css)
Then the problem is that you are changing your src attribute in your time loop, this ain't smooth
In your CSS, suppose you name your slider wrapper headerlogo_wrapper
div.headerlogo_wrapper > img {position:absolute;display:none;left:0;top:0}
Then you append your images to the space holder you have created (they will not show obviously)
Then you fadeIn your first image then you launch your setInterval :
//after having appended the images to the slider wrapper :
var $img = $("div.headerlogo_wrapper > img");
$img.eq(0).fadeIn(1000, "linear");
var ivisible = 0;
setInterval( function() {
$img.eq(ivisible).fadeOut(500);
++ivisible;
if (ivisible>$img.length-1) ivisible = 0;
$img.eq(ivisible).stop().fadeIn(1000, "linear");
}, 8000);
(If you want an image to be shown during load, some simple changes shall do; also if the first interval start immediately you obviously don't need to fadeIn "manually" the first image)
Try this: http://jsfiddle.net/3XV5M/
Your problem is the first time you run the timer function it won't run straight away. It will be run after 8000ms. The way this fiddle works is it will execute the function immediately and the run itself again after 8 seconds. Note I'm using setTimeout instead of setInterval.
function banner_rotator(imgid, imgarray, imgpos) {
if (imgpos >= imgarray.length || imgpos == undefined) imgpos = 0;
$("#"+imgid).attr({ "src" : imgarray[imgpos].src })
.fadeIn(1000, "linear")
.delay(6500)
.fadeOut(500);
imgpos++;
setTimeout(function() {banner_rotator(imgid, imgarray, imgpos) }, 8000);
}
The other problem is you need to hide the images first, so they can fade in. They wont fade in if they are already visible.
#headerlogo {
border-radius: 0px 0px 5px 5px;
width: 960px; height: 350px;
background-color: #d0d0d0;
display: none; /* Add this */
}
Then to prevent the other elements jumping up when you fade the images out, wrap the image element inside a div and set it's height. I used a div with a class of banner and added this style:
.banner {
height: 350px;
}
Hope that helps.
The problem is that you are fading out at the end of your interval. So replace this:
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000, "linear");
$("#"+imgid).delay(6500);
$("#"+imgid).fadeOut(500);
with this:
$("#"+imgid).fadeOut(500)
$("#"+imgid).queue(function(){
$("#"+imgid).attr({ "src" : imgarray[imgpos].src });
$("#"+imgid).fadeIn(1000);
$("#imgposspan").html(imgpos);
imgpos++;
$(this).dequeue();
});
JSFIDDLE demo
I have 5 diffrent backgrounds which change from one to another when mouseover menu links like that:
3 different screenshots out of 5
I want that the web site works properly in all browsers, but I get very different results. In firefox, background image dissapears and reappears on each menu link, but only first time when I go over a link with a cursor, other times works fine. In chrome backgrounds disappear and reappear on every onmouseover. And in IE onmouseover doesn't work at all nor the menu.
So I'm asking you to help me fix this, both things, dissapearing and the menu in IE. I found out that this disappearing and reappearing happens because of slow image loading, but I have no idea how to repair my code to fix this.
I just wrote my code in jsFiddle and menu doesn't work in it as well. And I noticed that when I downscale windows into the size smaller than div, the whole thing starts to deform. I thought I already fixed it, but it seems that I don't know how to that as well. You can see my code here:

For blinking background images, and other images which you want to use from JS, you need to preload, or it will be blinking. How to preload an image? Click here
(It's blinking, because when the page was loaded, the image wasn't. So, that image which you want to use, isn't at the user. The browser download it, but until that time, theres no image what it can show for him/her. This is the reason.)
IE is blocking JS in default (like IE 10). You need to enable it. I've got a warning bubble an the bottom, which say, I've blocking everything... or something like that. You can't enable this from script. Only you can create a warning message for the user, which you remove if JS is enabled.
An extra thing, in jsFiddle it will work the page if you select the "no warp - in <head>" option from the second drop down list at top left. After that you need to click run at top.
