Cycle2 - goto: skipping - javascript

Is there a way in Cycle2 to tell when the goto function is being skipped due to it already being on that slide.
I have some cases where it could handle and I want to handle this in a proper way, but I can't seem to find any event that's being triggered for this.
$slider.cycle('goto', 0); //[cycle2] goto: skipping, already on slide 0

The code for goto doesn't fire if you are targeting the current slide. You can see this in the source code (line 951 as of this writing):
if (num == opts.currSlide) {
opts.API.log('goto: skipping, already on slide', num);
return;
}
If the license allows it, remove that block from the code and handle the cycle-before event that will now be fired (I didn't test it, but I assume it will!). You could also directly implement your logic there or even add a custom event yourself, depending on what you are planning to do.

How to test 'HOVER' using Cypress(.trigger('mouseover') doesn't work)

I wonder if it's possible to test coverable dropdown menu bar using Cypress.
For example, when you go to Ebay(https://www.ebay.com), you'll see the alert icon at the top-right corner of the page and if you hover on that element, sign-in notification box will show up.
Here is my code and I followed what Cypress told me to do but I got an error like...
AssertionError
Timed out retrying: Expected to find element: #ghn-err, but never found it.
it('ebay hover test', () => {
cy.visit('https://www.ebay.com')
// 1. alert icon hover test.
cy.get('#gh-Alerts-i').trigger('mouseover')
cy.get('#ghn-err').should('be.visible')
// 2. This is my another test.
// cy.get('#gh-eb-My > .gh-menu > .gh-eb-li-a > .gh-sprRetina').trigger('mouseover')
//cy.get('#gh-eb-My-o > .gh-eb-oa thrd').should('be.visible')
})
For me mouseover works. It's a known Cypress bug pending to be solved.
However, try these:
cy.get('#gh-Alerts-i').trigger('onmouseover')
cy.get('#gh-Alerts-i').trigger('mouseenter')
cy.get('#gh-Alerts-i').invoke('trigger', 'contextmenu')
cy.get('#gh-Alerts-i').rightclick();
I had the same problem, I finally found this plugin that does exactly what I was looking for: do real events instead of simulated ones (simulated == launched with javascript).
https://github.com/dmtrKovalenko/cypress-real-events#cyrealhover
Just install it, add a line to cypress/support/index.js file (do not forget! See 'install' paragraph at the top of the page) and use cy.get(<element>).realHover().
If .trigger() does not work for you, it could also be that your display logic is controlled via CSS instead (for example with .class:hover). You could then rework the display logic to toggle a class with mouseenter and mouseleave events instead.

keyup function performing weird

So I got a little codepen. Everything works so far except a little thing. I got a <h1> and an <input>. When I type something in the text input, its value should get passed to the <h1> in realtime.
I tried to do that with a keyup function:
$('input[name=titleInput]').keyup(function(){
$('#title').text(this.value);
});
Something happens, but not what I want.When I type something in the text input, then delete it (with backspace) and re-enter something, only the first character gets passed to the title.Try it out on my codepen. Maybe it's just a stupid mistake of mine, but to me this behaviour is pretty weird.Thanks for your help in advance!EDIT:I am using text-fill-color, which may causes the problem.EDIT 2:A friend of mine tested it. It worked for her. She's using Chrome and the same version as me (58.0.3029.110 (official build) (64-Bit)).
Chrome does not update the content correctly. Such kind of bugs can always happen if you use vendor prefixed css properties, so you should avoid those.
You could hide the container before update, and then show it again with a timeout. This will trigger an update, but would also result in flickering.
$('input[name=titleInput]').keyup(function(){
$('.clipped').hide()
$('#title').text(this.value);
setTimeout(function() {
$('.clipped').show();
})
});
EDIT An alternative might be to use background-clip on the text and provide the inverted image yourself, but I right now don't have time to test that.
EDIT2 Based on the test of #TobiasGlaus the following code does solve the problem without flickering:
$('input[name=titleInput]').keyup(function(){
$('.clipped').hide().show(0)
$('#title').text(this.value);
});
This seems to be different to $('.clipped').hide().show() most likely it starts an animation with duration 0 and uses requestAnimationFrame which also triggers a redraw. To not relay on this jQuery behaviour, the code should be written as:
$('input[name=titleInput]').keyup(function(){
if( window.requestAnimationFrame ) {
$('.clipped').hide();
}
$('#title').text(this.value);
if( window.requestAnimationFrame ) {
window.requestAnimationFrame(function() {
$('.clipped').show();
})
}
});
i'd use the following lines:
$('input[name=titleInput]').bind('keypress paste', function() {
setTimeout(function() {
var value = $('input[name=titleInput]').val();
$('#title').text(value);
}, 0)
});
This will listen to the paste / keypress events, and will update the value on change.

Limiting click detection on the page [javascript]

I'm trying to limit the user's ability to click on an object to a certain time limit. I looked around and found that apparently, setTimeout() is the correct function to use for this type of thing. I've applied the function to my code, but its not working. I'm thinking/know now that the problem is that the setTimeout in my code isn't limiting the actual click event, which I need to do. Here is a snippet of my click code:
function clickRun(event) {
var $objectVersion = correspondingObject(event.target.id);
if (isAnyVisible() == false) { // none open
$objectVersion.makeVisible();
} else if (isAnyVisible() && $objectVersion.isVisible()) { //click already open div
$objectVersion.makeInvisible();
} else if (isAnyVisible() && $objectVersion.isVisible()==false) { //different div open
searchAndDestroy();
$objectVersion.delay(600).makeVisible();
};
};
$('.ChartLink').click(function(event) {
setTimeout(clickRun(event),5000);
});
I've also created a JSFiddle to represent what I'm talking about: http://jsfiddle.net/FHC7s/
Is there a way to achieve limiting the actual click detection on the page?
I think the easiest way to do it is to keep track of the time of the previous click and if the current click is too soon after that, then don't do anything:
onClick = function(){
if(new Date().getTime() - lastCheck < MIN_CLICK_SPACING) return;
}
Have a look at this JSFiddle, I've set it up so you can have the button disable itself for time duration after detecting a click. Just make sure to remember how your closures are operating with your setTimeouts.
Your code contains an error... your line should be
setTimeout(function(){clickRun(event)},5000);
but even then I don't think that's exactly what you're looking for; that code will "delay" the click by 5 seconds, not actually prevent more clicks. If your true intent is to ignore all clicks after a certain amount of time, then I would go with mowwalker's answer; there's no way to stop the clicks, but you can check to see if you should honor them or not.

Trigger event on animation complete (no control over animation)

I've a scenario that requires me to detect animation stop of a periodically animated element and trigger a function. I've no control over the element's animation. The animation can be dynamic so I can't use clever setTimeout.
Long Story
The simplified form of the problem is that I'm using a third party jQuery sliding banners plugin that uses some obfuscated JavaScript to slide banners in and out. I'm in need of figuring out a hook on slideComplete sort of event, but all I have is an element id. Take this jsfiddle as an example and imagine that the javascript has been obfuscated. I need to trigger a function when the red box reaches the extremes and stops.
I'm aware of the :animated pseudo selector but I think it will need me to constantly poll the required element. I've gone through this, this, and this, but no avail. I've checked jquery promise but I couldn't figure out to use that in this scenario. This SO question is closest to my requirements but it has no answers.
P.S. Some more information that might be helpful:
The element isn't created by JavaScript, it is present on page load.
I've control over when to apply the plugin (that makes it periodically sliding banner) on the element
Most of the slideshow plugins I have used use changing classes at the end of the animation... You could extend the "addClass" method of jQuery to allow you to capture the class change as long as the plugin you use is using that method like it should:
(function($){
$.each(["addClass","removeClass"],function(i,methodname){
var oldmethod = $.fn[methodname];
$.fn[methodname] = function(){
oldmethod.apply( this, arguments );
this.trigger(methodname+"change");
return this;
}
});
})(jQuery);
I threw together a fiddle here
Even with obfuscated code you should be able to use this method to check how they are sending in the arguments to animate (I use the "options" object when I send arguments to animate usually) and wrap their callback function in an anonymous function that triggers an event...
like this fiddle
Here is the relevant block of script:
(function($){
$.each(["animate"],function(i,methodname){
var oldmethod = $.fn[methodname];
$.fn[methodname] = function(){
var args=arguments;
that=this;
var oldcall=args[2];
args[2]=function(){
oldcall();
console.log("slideFinish");
}
oldmethod.apply( this, args );
return this;
}
});
})(jQuery);
Well since you didn't give any indication as to what kind of animation is being done, I'm going to assume that its a horizontal/vertical translation, although I think this could be applied to other effects as well. Because I don't know how the animation is being accomplished, a setInterval evaluation would be the only way I can guess at how to do this.
var prevPos = 0;
var isAnimating = setInterval(function(){
if($(YOUROBJECT).css('top') == prevPos){
//logic here
}
else{
prevPos = $(YOUROBJECT).css('top');
}
},500);
That will evaluate the vertical position of the object every .5 seconds, and if the current vertical position is equal to the one taken .5 seconds ago, it will assume that animation has stopped and you can execute some code.
edit --
just noticed your jsfiddle had a horizontal translation, so the code for your jsfiddle is here http://jsfiddle.net/wZbNA/3/

How can I know when a video inside a <video></video> element has been entirely loaded?

I want to detect through jQuery or Javascript when a specific video inside an html5 tag has been entirely loaded (I mean, downloaded into the cache of the browser). The video has the preload = "auto" attribute.
I tried everything in my power to do this (I'm a beginner) with no luck. Can't seem to find any event I could listen to, is there any way to do this?
PS: the only thing I came across is the network_state property of the video object, but the references around the web doesn't seem to agree with the state it returns, and when I tried it I didn't find a state for "LOADED".
EDIT: I found an event I think I can use, the canPlayThrough. I tested it and it seemed to work, but I'm not sure if it really tells me that the video has been totally loaded, or just that it loaded enough data to start playing (which is no good).
You can bind to the ended event :
$("video").bind(eventname, function() {
alert("I'm done!");
});
Where eventname is the event you want to list to
A complete list of events is here -> http://dev.w3.org/html5/spec/Overview.html#mediaevents
UPDATED :
To get a percentage loaded you can use a combination of 2 events :
$("video").bind('durationchange', checkProgress);
$("video").bind('progress', checkProgress);
function updateSeekable() {
var percentageComplete = (100 / (this.duration || 1) *
($(this).seekable && $(this).seekable.length ? $(this).seekable.end : 0)) + '%';
}
