I'm using $ionicSlideBoxDelegate.next() with a custom button to advance a slider. That works fine.My goal is to slow down the slide animation when someone actually pressed the next button.
Sadly some versions of ionic have some inconsistency based on documentation. You can try $ionicSlideBoxDelegate.slide(slideNumber, speed). And create an index on scope to control slideNumber. :/
var slide = $ionicSlideBoxDelegate;
var nextIndex = slider.currentIndex()+1;
slider.slide(nextIndex,1000);
Once I get to the final slide I want to disable the bounce effect that happens when you try and swipe further. I have ion-option-buttons on the final page and swiping them causes the screen to wobble due to the slides.
I still want to be able to move back to the left / previous slide
If you aren't using the Swiper widget I would recommend it because it offers a lot more flexibility/options with your slide boxes. (Ionic documention on it here, as well).
All you need to do is watch the slide delegate, if you hit the last slide, lock sliding to next (stops the bouncy effect you mentioned). Then unlock sliding if you are not on the last slide.
$scope.$watch('data.sliderDelegate', function(newVal, oldVal) {
if (newVal != null) {
$scope.data.sliderDelegate.on('slideChangeEnd', function() {
$scope.data.currentPage = $scope.data.sliderDelegate.activeIndex;
if($scope.data.currentPage == $scope.data.lastSlide){
$scope.data.sliderDelegate.lockSwipeToNext();
}
else{
$scope.data.sliderDelegate.unlockSwipeToNext();
}
$scope.$apply();
});
}
});
Here is a codepen for the exmaple.
I know this is an old post, but I just managed this in Ionic 4.0, and though that someone might find some value in it.
You can use the command:
this.slides.lockSwipeToNext(true);
To prevent the user from swiping right. There is similarly another command to prevent it going left:
this.slides.lockSwipeToPrev(true);
I placed it in the " ionViewWillEnter()" function to initially disable the swiping, then created a function that I call whenever I want to manually move to the next slide like this:
ionViewWillEnter(){
this.slides.lockSwipeToNext(true);
}
nextSlide(){
this.slides.lockSwipeToNext(false);
this.slides.slideNext();
this.slides.lockSwipeToNext(true);
}
Hope this helps someone looking for a similar soution.
In my controller i am using $firebaseArray and $ionicScrollDelegate to show messages in a chat. when my $firebaseArray is loaded, i am using the scroll delegate to scroll to the bottom and it works fine, no issues there.
But when a new child is added, i am again using scroll delegate to scroll to bottom, that scrolls down without any issues but it freezes the scroll, i.e i am not able to scroll back to the top
code
chat.html
<ion-content delegate-handle="mainScroll">
//chat list
</ion-content>
chat controller
app.controller('chatCtrl',function($scope,$firebaseArray,$ionicScrollDelegate){
var chatRef = new Firebase("my ref");
$scope.messages = $firebaseArray(chatRef);
$scope.messages.$loaded().then(function(){
$ionicScrollDelegate.$getByHandle('mainScroll').scrollBottom(true);
});
chatRef.on('child_added', function(childSnapshot, prevChildKey) {
$ionicScrollDelegate.$getByHandle('mainScroll').scrollBottom(true);
});
});
I believe you are using android phone to test right? If android I'm pretty sure there have a bug by using animation to scroll to bottom. Have you try to remove the animation by delete 'true' value on the function? Ex:
$ionicScrollDelegate.$getByHandle('mainScroll').scrollBottom(true);
to
$ionicScrollDelegate.$getByHandle('mainScroll').scrollBottom();
Try It.. hope it helps you.
UPDATE (SOLUTION):
Okay I found the solution.. It seem we need to set 'jsScrolling: true' instead of by default is 'jsScrolling: false' for android.
Please modified/edit this on 'ionic-angular.js'
Hope it helps others :)
I'm trying to get this horizontal scrolling Plugin from Waypoints to work and it appears that there must be something outside of my knowledge that is missing.
Here's a codepen I made of the 1 and only example they had. It's supposed to trigger a little pop up notifier. Firstly, I'd like to see that this really works before I put anymore time/frustration into it - but I'd also like to attach an addClass or toggleClass to it.
var waypoint = new Waypoint({
element: document.getElementById('horizontal-waypoint-offset'),
handler: function(direction) {
notify('right-in-view waypoint triggered')
},
context: document.getElementById('overflow-scroll-offset'),
horizontal: true,
offset: 'right-in-view'
})
Codepen:
http://codepen.io/code-a-la-mode/pen/vOPWgM
Demo on Waypoint site:http://imakewebthings.com/waypoints/api/horizontal-option/
(ultimate use for this: I have a vimeo frame that slides in from an absolute left offscreen. I plan to have this toggle play/pause as it enters/leaves the viewport.)
I'd appreciate just seeing this work in any capacity, but if anyone wants to show off and make an example of it controlling play/pause as a vimeo (or youtube) screen slides in from off screen, I wouldn't mind AT ALL :)
The version of Waypoints you're using in that Pen is very old, 1.1.6. Creating waypoints using new Waypoint wasn't a feature until 3.0. Please try updating.
I am having a bit of a weird problem with iOS platform for a page i am developing. This is the page in question. When clicking any of the case study images, the page will first unhide the required case study then scroll to it.
This works on all desktop browsers on Windows and Mac, but on the iPhone and iPad you get a horrible flicker as it scrolls down.
Not quite sure how to debug or fix this issue.
Any ideas would be of great help!
Thanks in advance,
Shadi
UPDATE 1
The latest page can be found here. Still haven't found a fix - if anyone has any idea it would be amazing!
If you need vertical scroll only, you could use {'axis':'y'} as settings to scrollTo method.
$.scrollTo(*selector*, *time*, {'axis':'y'});
Have you tried this:
$('a[href=#target]').
click(function(){
var target = $('a[name=target]');
if (target.length)
{
var top = target.offset().top;
$('html,body').animate({scrollTop: top}, 1000);
return false;
}
});
If you're just scrolling the page vertically you can replace the entire jQuery scrollTo plugin with this simple line:
$('html,body').animate({scrollTop: $("#scrollingTo").offset().top}, 1000, 'easeOutCubic');
Personally I do something like this
$('html,body').animate({scrollTop: $("#step-1").offset().top-15}, 1000, 'easeOutCubic',function(){
//do stuff
});
I found that if I try to do other js work while it's scrolling it makes the browser crunch and the animation isn't smooth. But if you use the callback it'll scroll first, then do what you need.
I put a -15 at the end of .top because I wanted to show the top edge of the div I was scrolling do, simply for aesthetic purposes. 1000 is the duration in milliseconds of the animation.
Credit goes to the poster, animate, for the tip off.
Defining {'axis':'y'} has made it right! It helped me with slideUp/Down flickering.
I'm not sure if this applies to jquery animations. But the following seems to affect CSS animations.
http://css-infos.net/property/-webkit-backface-visibility
Syntax
-webkit-backface-visibility: visibility;
Parameters
visibility
Determines whether or not the back face of a transformed element is visible. The default value is visible.
edit
Try applying it to every element and see what happens.
*{
-webkit-backface-visibility: visible;
}
and try
*{
-webkit-backface-visibility: hidden;
}
It's just a guess really...
I will also confirm Tund Do's method works flawlessly. If you need a "left/right" variation of the same thing (as I did) here it is:
$('.pg6').click(function(){
var target = $('#page6');
if (target.length)
{
var left = target.offset().left;
$('html,body').animate({scrollLeft: left}, 1000);
return false;
}
});
I would guess you could combine the two, grab the top position and chain the animates for a "left/right/up/down" animation also.
I had the same problem.
The problem is the ScrollTo plugin. Instead of using scrollto.js just use .animate with scrollTop. No more flickering in ipad/iphone.
Here it is with no flickering http://www.sneakermatic.com
You should include {axis: 'y'} in your options object. Also be sure that you have not enabled interrupt option. You can test this with {interrupt: false}.
You need to add e.preventDefault(); to each .click() call. This prevents the browser's default action, which is to stay in the same place. Hope this helps!
i.e.
$("#quicksand li, .client-list li").click(function (e) {
e.preventDefault();
...
});
I'm having the same flickering on iPhone -- even with the preventDefault and return false options of canceling the default click event. It appears that on the device it tries to go back to the top of the page before scrolling. If you have both a scrollTop and scrollLeft animation going on it really gets buggy. It's jQuery's issue.. I've seen a scrolling method with mootools that doesn't have this issue. See this page: http://melissahie.com/
Thanks nicole for giving the example with mootools.
It really seems to be a jQuery issue when trying to do a animation on BOTH scrollTop and scrollLeft.
With mootools:
var scroll = new Fx.Scroll(window, {duration: 1000, wait: false, transition: Fx.Transitions.quadInOut});
scroll.start(y, x);
it works flawlessly on iOS5!
