I'm using a mixture of CSS/JS to create some simple page slide transitions for new pages, that will eventually be loaded dynamically by AJAX, however on creation of the new element "main2" which has the necessary -webkit-transition etc. it does not slide in like it should, but simply appears. The previous page however slides out fine, using basically the same code.
As well as this, changing the slide in to after the animation for the previous page has finished like so:
function newPage() {
var newMain = document.createElement("div");
newMain.className = "main";
newMain.style.left = "100vw";
newMain.id = "main2";
newMain.style.zIndex = 1999;
newMain.style.background = "#AAA";
document.body.appendChild(newMain);
oldMain = document.getElementById("main");
oldMain.style.left = "-50vw";
setTimeout(function() {
newMain.style.left = "50vw";
oldMain.parentNode.removeChild(oldMain);
newMain.id = "main";
}, 1000);
}
makes it animate in, just not at the right time.
Any help would be appreciated, I'm sure it's just something glaringly simple that I've missed.
Demo: JSFiddle
Try this: http://jsfiddle.net/5raj05th/8/
I changed the code so you do trigger the transition by adding the style:
newMain.style.left = "100vw";
and later:
newMain.style.left = "0";

I'm trying to speed up or remove the wipeIn and wipeOut animation of a title pane in Dojo. The content should appear immediately after clicking on the title bar. In other frameworks, I would modify the animation speed or duration but I had no luck with this in dojo so far. I've also tried to overwrite the animation without too much success.
This is (simplified) how I create the TitlePane:
require(["dijit/TitlePane", "dojo/dom-construct"], function(TitlePane, domConstruct){
var titlePaneOptions = {};
titlePaneOptions.title = "Some Title";
titlePaneOptions.open = true;
titlePaneOptions.content = "Content";
this._titlePane = new TitlePane(titlePaneOptions);
domConstruct.place(this._titlePane.domNode, this.context.element, "only");
this._titlePane.startup();
});
Check the API docs for TitlePane, under Property Summary, there is a duration:
duration - Time in milliseconds to fade in/fade out
So for example:
var titlePaneOptions = {};
titlePaneOptions.title = "Some Title";
titlePaneOptions.open = true;
titlePaneOptions.content = "Content";
titlePaneOptions.duration = 0;
.. should make it appear/disappear immediately.
How do I flow a text stream from one div to the next? Each div has a fixed height and width and I need the data to be passed to the first, then if that is filled overflow to another etc. (The second etc. divs need to be dynamically created). Eventually the divs will be contenteditable, this is the page technique for a simple WYSIWYG style editor.
Please help...

What you're looking for is called CSS Regions. This allows your text to flow through various containers placed on your site.
You can read about it on Adobe's site, and Apple has a nice WWDC video explaining how to implement it (starts at 8:40). Also check out the Editor's Draft.
I'm attempting to create a slide out panel that appends to the container div within the header and footer of my page. I'm using Bootstrap for responsive, so the solution should ideally work with the media-queries contained within that package. I'm really at a loss on how to approach this because everything I've tried doesn't seem to work in some way or another.
This picture animates best what I'm trying to accomplish (sorry not a designer):
http://d.pr/i/DzQc+
What I've tried:
Pageslide - this is was the closest solution I've found so far. this appends the slide out panel to the body. As such it doesn't allow me to keep the slide out panel within the header/footer container of the page: http://srobbin.com/jquery-plugins/pageslide/
jQuery Mobile Panel Widget - I tried to hack and repurpose the jQuery mobile panel widget plugin to function as desired without any luck.
.append Function - I tried to animate the .append function but this didn't work with the responsive functions of bootstrap.
With that all said, do any of you have a suggestion on a plugin, function or implementation that may work? I'm not necessarily looking for a working piece of code, rather I'm looking for a direction that will work as I'm hoping.
Thanks!
Here is a popup container in a prototype pattern I built that you can create to any div. CSS it up to style to your liking

I want to be able to do a cross fade transition on large images whose width is set to 100% of the screen. I have a working example of what I want to accomplish. However, when I test it out on various browsers and various computers I don't get a buttery-smooth transition everywhere.
See demo on jsFiddle: http://jsfiddle.net/vrD2C/
See on Amazon S3: http://imagefader.s3.amazonaws.com/index.htm
I want to know how to improve the performance. Here's the function that actually does the image swap:
function swapImage(oldImg, newImg) {
newImg.css({
"display": "block",
"z-index": 2,
"opacity": 0
})
.removeClass("shadow")
.animate({ "opacity": 1 }, 500, function () {
if (oldImg) {
oldImg.hide();
}
newImg.addClass("shadow").css("z-index", 1);
});
}
Is using jQuery animate() to change the opacity a bad way to go?
You might want to look into CSS3 Transitions, as the browser might be able to optimize that better than Javascript directly setting the attributes in a loop. This seems to be a pretty good start for it:
http://robertnyman.com/2010/04/27/using-css3-transitions-to-create-rich-effects/
I'm not sure if this will help optimize your performance as I am currently using IE9 on an amped up machine and even if I put the browser into IE7 or 8 document mode, the JavaScript doesn't falter with your current code. However, you might consider making the following optimizations to the code.
Unclutter the contents of the main photo stage by placing all your photos in a hidden container you could give an id of "queue" or something similar, making the DOM do the work of storing and ordering the images you are not currently displaying for you. This will also leave the browser only working with two visible images at any given time, giving it less to consider as far as stacking context, positioning, and so on.
Rewrite the code to use an event trigger and bind the fade-in handling to the event, calling the first image in the queue's event once the current transition is complete. I find this method is more well-behaved for cycling animation than some timeout-managed scripts. An example of how to do this follows:
// Bind a custom event to each image called "transition"
$("#queue img").bind("transition", function() {
$(this)
// Hide the image
.hide()
// Move it to the visible stage
.appendTo("#photos")
// Delay the upcoming animation by the desired value
.delay(2500)
// Slowly fade the image in
.fadeIn("slow", function() {
// Animation callback
$(this)
// Add a shadow class to this image
.addClass("shadow")
// Select the replaced image
.siblings("img")
// Remove its shadow class
.removeClass("shadow")
// Move it to the back of the image queue container
.appendTo("#queue");
// Trigger the transition event on the next image in the queue
$("#queue img:first").trigger("transition");
});
}).first().addClass("shadow").trigger("transition"); // Fire the initial event
Try this working demo in your problem browsers and let me know if the performance is still poor.
I had the same problem too. I just preloaded my images and the transitions became smooth again.
The point is that IE is not W3C compliant, but +1 with ctcherry as using css is the most efficient way for smooth transitions.
Then there are the javascript coded solutions, either using js straight (but need some efforts are needed to comply with W3C Vs browsers), or using libs like JQuery or Mootools.
Here is a good javascript coded example (See demo online) compliant to your needs :
var Fondu = function(classe_img){
this.classe_img = classe_img;
this.courant = 0;
this.coeff = 100;
this.collection = this.getImages();
this.collection[0].style.zIndex = 100;
this.total = this.collection.length - 1;
this.encours = false;
}
Fondu.prototype.getImages = function(){
var tmp = [];
if(document.getElementsByClassName){
tmp = document.getElementsByClassName(this.classe_img);
}
else{
var i=0;
while(document.getElementsByTagName('*')[i]){
if(document.getElementsByTagName('*')[i].className.indexOf(this.classe_img) > -1){
tmp.push(document.getElementsByTagName('*')[i]);
}
i++;
}
}
var j=tmp.length;
while(j--){
if(tmp[j].filters){
tmp[j].style.width = tmp[j].style.width || tmp[j].offsetWidth+'px';
tmp[j].style.filter = 'alpha(opacity=100)';
tmp[j].opaque = tmp[j].filters[0];
this.coeff = 1;
}
else{
tmp[j].opaque = tmp[j].style;
}
}
return tmp;
}
Fondu.prototype.change = function(sens){
if(this.encours){
return false;
}
var prevObj = this.collection[this.courant];
this.encours = true;
if(sens){
this.courant++;
if(this.courant>this.total){
this.courant = 0;
}
}
else{
this.courant--;
if(this.courant<0){
this.courant = this.total;
}
}
var nextObj = this.collection[this.courant];
nextObj.style.zIndex = 50;
var tmpOp = 100;
var that = this;
var timer = setInterval(function(){
if(tmpOp<0){
clearInterval(timer);
timer = null;
prevObj.opaque.opacity = 0;
nextObj.style.zIndex = 100;
prevObj.style.zIndex = 0;
prevObj.opaque.opacity = 100 / that.coeff;
that.encours = false;
}
else{
prevObj.opaque.opacity = tmpOp / that.coeff;
tmpOp -= 5;
}
}, 25);
}
I am in need a link that will flash every 500 milleseconds, for a duration of 5 seconds...
I remember long ago having a link like this, but deleted it because one could only click it when it was visible. Is there a workaround for that?
Try this:
<script type="text/javascript">
var col = new String();
var x=1;var y;
function blink()
{
if(x%2)
{
col = "rgb(255,0,0)";
}else{
col = "rgb(255,255,255)";
}
aF.style.color=col;x++;if(x>2){x=1};setTimeout("blink()",500);
}
</script>
<body onload="blink()">
<a id="aF" href="http://www.google.com"><b>*Google!*</b><br>
There is a JavaScript function in Script.aculo.us to do that : Have a look on Effect.Pulsate
There is CSS
text-decoration: blink
but that will blink your link all the time, you would need some javascript to change the style after 5 seconds.
Remember to always keep usability for all users in mind. Especially if you're making something flash at a certain frequency. Just be careful.
'A' quick JQuery UI version...
Links need CLASS 'flasher', and an ID
Will start on mouseover...and stop on mouseout.
Also add the secondarycolor as a hover to the 'A' link...it will help mask the initial interval delay at start.
var flashInterval;
var flasherId;
var firstColor = '#EF7F2C';
var secondaryColor = '#3296C8';
var flashTime = 300;
jQuery('a.flasher').mouseover(function() {
if(flasherId){ jQuery('#'+flasherId).animate({ color:firstColor},0); }//stop any previous flashing link
flasherId = jQuery(this).attr('id');//get id of current link
//set interval
flashInterval = setInterval(function(){ jQuery('#'+flasherId).animate({ color:secondaryColor},flashTime).animate({ color:firstColor},flashTime); },flashTime*2);
}).mouseout(function() {
clearInterval(flashInterval);//clear interval
jQuery('#'+flasherId).animate({ color:firstColor},0);//reset flasher
flasherId = '';//clear flasher var
});
