Trying to interpret jQuery again - how do I pause on video play? - javascript

Ok, I'm trying to modify some already written jQuery - as background, I know Javascript decently, but I'm only so-so with jQuery. My understanding of this code is that there's a scrolling bar, which will change every 6 seconds. I am unsure if there's any video specific code in here though - right now the scrollbar has a video embedded on one of the panes, which is clicked on.
What I am trying to do, is set up an image (currently inside <div class=vid>, not shown), which when it is clicked, will stop the paning, UNTIL one of the buttons at the bottom is clicked, and it will also play a flash video.
Here's the code:
<script type="text/javascript">
jQuery(document).ready(function() {
var scroll_item = jQuery("#chained").scrollable({circular: true, mousewheel: false}).navigator().autoscroll({
interval: 6000,
autoplay: false,
autopause: false
});
window.scroll_control = scroll_item.data("scrollable");
scroll_control.play();
var $playBtn = $('#p-p-btn');
$playBtn.click(function(){
if($(this).hasClass('play')){
$(this).addClass('pause');
$(this).removeClass('play');
scroll_control.play();
} else if($(this).hasClass('pause')) {
$(this).addClass('play');
$(this).removeClass('pause');
scroll_control.stop();
};
});
jQuery('#chained').hover(
function() { scroll_control.stop(); },
function() {
if ($playBtn.hasClass('pause')) {
scroll_control.play();
}
}
);
});
</script>
I believe all I have to do is add a condition which will determine if the image has been clicked (it is in <div class=vid>, but I am going to give it an id as well probably), which will turn the paning off (perhaps by "clicking" the play/off button?), and it will also launch the video with an auto play setting.
Does that sound accurate?
How would I turn the paning off?

I don't fully understand the code, because i don't know the whole context.
But try to add this in your document ready:
$("#YOURIMAGEID").bind("click",function(){
scroll_control.stop();
$('#p-p-btn').addClass('play');
$('#p-p-btn').removeClass('pause');
//other logic
});

Randomize slides in reveal.js

I have a reveal.js presentation with approximately 300 slides. The purpose of this presentation is to cycle slides in "kiosk mode" on a monitor behind a conference booth.
To create a "kiosk mode" I've got:
Reveal.initialize({
controls: false, // hide the control arrows
progress: false, // hide the progress bar
history: false, // don't add each slide to browser history
loop: true, // loop back to the beginning after last slide
transition: fade, // fade between slides
autoSlide: 5000, // advance automatically after 5000 ms
});
This works very well, but I'd like to randomize the slides. The slides are currently just a list of 300 <section> tags in the index document - they aren't being pulled from anywhere external. Currently random: true isn't a configuration option in reveal.js.
The display order of fragments can be controlled with data-fragment-index. Is it possible to do something like that with sections? Is there a way to trick reveal.js into randomizing my slides?
My preference would be to shuffle them each time around - that is, to show slides 1-300 in random order, and then shuffle them, and show 1-300 again in a different random order. I would also be happy with just jumping to a random slide for each transition, though.
While Reveal itself does not have this functionality built in, it does let you set up event hooks to do actions when all the slides are loaded, this means JQUERY TO THE RESCUE!
You can combine Reveal's "All slides are ready" event with simple javascript to reorder all the sections, here's a simple PoC:
First import jQuery, I did this by adding it directly above the import for js/reveal.min.js:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
Then, set up an event listener:
Reveal.addEventListener('ready', function(event) {
// Declare a function to randomize a jQuery list of elements
// see http://stackoverflow.com/a/11766418/472021 for details
$.fn.randomize = function(selector){
(selector ? this.find(selector) : this).parent().each(function(){
$(this).children(selector).sort(function(){
return Math.random() - 0.5;
}).detach().appendTo(this);
});
return this;
};
// call our new method on all sections inside of the main slides element.
$(".slides > section").randomize();
});
I put this right after declaring my Reveal settings and dependencies, but I'm pretty sure you can put it anywhere.
What this does is waits for all javascript, css, etc to load, manually reorders the slides in the DOM, then lets Reveal start off doing its thing. You should be able to combine this with all your other reveal settings since it's not doing anything disruptive to reveal itself.
Regarding the "shuffling them each time around" portion, the easiest way to do this would be to use another event listener, slidechanged. You could use this listener to check if the last slide has just been transitioned to, after which the next time slidechanged is called you could simply refresh the page.
You can do this with something like:
var wasLastPageHit = false;
Reveal.addEventListener('slidechanged', function(event) {
if (wasLastPageHit) {
window.location.reload();
}
if($(event.currentSlide).is(":last-child")) {
// The newly opened slide is the last one, set up a marker
// so the next time this method is called we can refresh.
wasLastPageHit = true;
}
});
As of reveal.js 3.3.0 there is now a built in helper function for randomizing slide order.
If you want the slide order to be random from the start use the shuffle config option:
Reveal.initialize({ shuffle: true });
If you want to manually tell reveal.js when to shuffle there's an API method:
Reveal.shuffle();
To shuffle the presentation after each finished loop you'll need to monitor slide changes to detect when we circle back to the first slide.
Reveal.addEventListener( 'slidechanged', function( event ) {
if( Reveal.isFirstSlide() ) {
// Randomize the order again
Reveal.shuffle();
// Navigate to the first slide according to the new order
Reveal.slide( 0, 0 );
}
} );

jQuery Booklet plugin stop auto play after one flip

I am using the jQuery Booklet plugin to flip page in my application. I need that the flip will be done automatically (without the user input) and will stop exactly after one flip.
I implemented the auto play according to the instruction
$(function() {
$('#mybook').booklet({
auto: true
});
and now I want to add the "pause" call but in the instruction page
http://builtbywill.com/code/booklet/demos/auto
there is only example where the pause is done by clicking on the pause link
$(function() {
$('#mybook').booklet({
auto: true,
play: '#play',
pause: '#pause'
});
});
and I need it to be done without a user input.
I will appreciate your help in this problem
Thanks
create your book
$(function() {
$('#mybook').booklet({);
});
This will flip the first page. if you have more that 2 pages.
$('#mybook').booklet("next");
OR
you can set timeout if you want some delay
for example
setTimeout(function (){
$('#mybook').booklet("next");
}, 1000);
this will give it a one second delay before flipping the page

Why is bxslider duplicating my divs

My designer put a bxslider to scroll through 3 divs nicely on my page.
When the page runs, in the html I see it generates 6 divs on the page. It shows div 3, div2, div1, div3, div2, div1.
Just because the duplicated fields on my page now mess up my programing.
Is that neccesary, and is there any way I can touch the code that it shouldn't duplicate my divs?
The page is full of complex code , with an ajax passing the data-serialize to a post form.
Becuase it's all duplicated, now all fields are coming through as 'value,value'. Therefore it's not giving me accurate respones, and well as undefined when it's supposed to be numeric.
My form posts looks like this:
function submitCart () {
$.post(
"scripts/savecart.asp",
$("#form1").serialize()
);}
How could I add that not bx- to it?
As commented in the source code of bxSlider:
if infinite loop, prepare additional slides
So I was able to fix this by adding infiniteLoop: false to the config object:
$(".js-slider").bxSlider({
infiniteLoop: false
});
BxSlider duplicates elements to allow infinite scrolling, etc. For example, say you only have two elements in your slider. Element one might be sliding out on the left, but also sliding in on the right. Therefore, duplicates are required.
If this is a problem, you can usually interact with the duplicates using their bx-clone classes. If you could clarify the actual problem, we could probably give more specific advice.
Update: To eliminate cloned elements from your set, try something like:
$('.bxslider li:not(.bx-clone)')....
I had such problem with bx-clone
I want to use it for an image gallery. So I had a thumbnail image slider and for slider I used bx-slider and on each click on small image , that image in bigger size must show in a div , But on bx-clone clicked nothing happened
I solved that problem with this :
var slider = $('.bxslider').bxSlider({
minSlides: 4,
maxSlides: 4,
slideWidth: 92,
moveSlides: 1,
pager: false,
slideMargin: 10,
onSliderLoad: function(){
$('li.bx-clone').click(function() {
/** your code for bx clone click event **/
});
}
});
Adding to #antongorodezkiy's answer, there is a way to have infiniteLoop: false and still get a non-stopping slide changing: using the onSlideAfter event of the last slide you can, after a few seconds, go back to the first slide and re-start the auto mode:
var pauseTime = 4000; //Time each slide is shown in ms. This is the default value.
var timeoutId;
var slider = $('.bxslider').bxSlider({
auto: true,
infiniteLoop: false,
pause: pauseTime,
onSlideAfter: function ($slideElement, oldIndex, newIndex) {
if (newIndex === slider.getSlideCount() - 1) { //Check if last slide
setTimeout(
function () {
slider.goToSlide(0);
slider.startAuto(); //You need to restart the "auto" mode
},
pauseTime //Use the same amount of time the slider is using
);
}
else { //In case the user changes the slide before the timeout fires
clearTimeout(timeoutId);
slider.startAuto(); //Doesn't affects the slider if it's already on "auto" mode
}
}
});
The difference between this solution and the infiniteLoop: true option is that instead of smoothly transitioning back to the first slide as if it was the next, the slider quickly "rewinds" until reaching the first slide.
for above query: Is it possible to keep having the infinite loop, but remove the clones?
try using below code: if more than 1 item infiniteloop: true else :false
infiniteLoop: ($j("...selector...").length < 2) ? false : true,
Just to answer here, so if some one is struggling and cannot fix the duplication issue. I was facing the same problem that all of my HTML from my page was duplicating inside the first slide under the image tag like bellow:
<img src="public/admin/scr3.png" ><div>..... all of my page HTML...</div></img>
I just found that I was writing the image tag not properly
Meaning my code was something like this for image tag
<img src="public/admin/scr3.png" >
I just replaced my image tag with valid HTML like bellow:
<img src="public/admin/scr3.png" />
and it fixed the content duplication issue.
Hope it will help someone.
Cheers!
I´m not sure if it´s the same issue I was facing, but here´s my case:
My code was using bx slider together with fancybox. And it was duplicating my slides. The solution was to put the secodary code (fancy box), which was generated in my image loop, inside the tag. That did it for me.

jCarouselLite Rebinding Data

I have a jCarouselLite plug in on my website. I am loading the li's from a jquery.load function. I cycle through the carousel vertically and have a function that triggers as soon as the first item comes back around to the top.
At this point, I want to refresh the data with another ajax.load. This is where I run into a problem. Once that data is reloaded, the carousel stops rotating (or rather, is running in the background).
One solution I tried is to try re-instating the carousel with another:
$("#tableapp").jCarouselLite({})
line. This seems to cause two carousels to be running at the same time. And then a third, and 4th, and so on.
So basically I am looking for some way to clear the carousel, reload the updated data, then run it again. Any ideas?
$(document).ready(function () {
updateConsole() //Gets new data
scrollWindow() //Starts carousell
});
function updateConsole() {
$('#tableapp').load('AjaxPages/ApplicationMonitor.aspx #application');
}
function scrollwindow() {
$("#tableapp").jCarouselLite({
vertical: true,
hoverPause: true,
visible: 4,
auto: 6000,
speed: 500,
scroll: 4,
circular: true,
afterEnd: function (a) { ScrollEnd(a); }
});
};
function ScrollEnd(a) {
$('#tbDebug').val($('#tbDebug').val() + '\nScroll Ends');
if (**code that determines slide 1 is back on top**) {
updateConsoles();
scrollWindow(); //If this code is commented, the carousel stops cycling.
//If it isn't commented, two carousels start and things
//get buggy and eventually freezes.
}
}
I am pretty new to javascript, jquery, etc. I also tried this on jCarousel (not lite), but I couldn't get it working with vertical scrolling. It seemed buggy.
Here's a not-particulary thought out suggestion:
When you ScrollEnd, .remove that div.
http://api.jquery.com/remove/
Then recreate it and dump load into it.
Creating a div element in jQuery
Does that trick it into working?

Disable a next/previous button(link) temporarily when clicked in jQuery Cycle plugin (not necessarily a jquery cycle issue)

I need to prevent link from being clicked for let's say 2 seconds.
Here is an example http://jsbin.com/orinib/4/edit
When you look at the rendered mode you see next and prev links. When you click next, it slides with a nice transition. However if you click multiple times there is no transition sort of, which is expected. But my question: is this how can I prevent clicking on the next link, for about 2 seconds (or what ever time it takes for transition to happen) so that no matter what transition will occur.
This is what I tried to use, but did not work:
function(){
var thePreventer = false;
$("#next").bind($(this),function(e){
if(!thePreventer){
thePreventer = true;
setTimeout(function(){
thePreventer = false;
}, 2000);
}else{
e.preventDefault();
}
});
}
Which I got from here "Disable" a link temporarily when clicked? I think. I believe that i cannot achieve this effect with this code (although it works on other links). I believe this is due to the fact that cycle-plugin got a hold of that link, and I understand that I have to bind/tap-into this functionality of the plugin. Please note: that this code may not work I just used it to show that I tried it and it did not work, you can reuse it if you have to or give me your own stuff.
Please help, if you can.
EDIT:
As mrtsherman proposed this simple yet elegant ANSWER: http://jsfiddle.net/LCWLb.
Take a look at the cycle options page. There are a number of ways to do this. I would consider using the pager event onPrevNextEvent. You can assign a callback function.
$('#slideshow').cycle({
pager: '#nav',
onPrevNextEvent: function(isNext, zeroBasedSlideIndex, slideElement) {
//disable controls
},
after: function(currSlideElement, nextSlideElement, options, forwardFlag) {
//reenable controls
}
});
The following will temporarily prevent clicks while a slideshow is running, as shown in this fiddle:
$.fn.extend({
delayClick: function(callback) {
this.bind('click', function(e) {
$self = $(this);
if( $self.hasClass('disabled') ) {
$('#log').append('<p>click prevented on '+$self.attr('id')+'</p>');
}
else {
$self.addClass('disabled');
callback.call(this, [arguments]);
setTimeout(function() {
$self.removeClass('disabled');
}, 1000);
}
return false;
});
}
});
