I'm using perfect-scrollbar to scroll large tables on the x-axis.
When the option useBothWheelAxes is set to true I can use the mouse wheel to scroll the table horizontally. When I reach the end of the table, I'd like to keep scrolling down the page.
Looking at the documentation, I'd expect I can use wheelPropagation for this:
If this option is true, when the scroll reaches the end of the side, mousewheel event will be propagated to parent element.
Vertically this does work. However, this doesn't seem to work when scrolling horizontally.
A demo identifying the problem can be found here: https://codepen.io/anon/pen/YaXBoV

I wasn't able to find any events to hook into for this - I want to take control over the scroll distance when the user does things like moving the mouse wheel, clicking a scroll button (up or down), clicking the empty space of a scroll bar, etc.
For example, if I have a list of things, and each row is 16px tall, how would I be able to force it to scroll 16 pixels for single scroll events (i.e. mouse wheel up/down, or clicking the scroll button, if one exists)? And then, if scrolling by clicking the empty scroll bar, how can I ensure it scrolls by a fixed amount, so when it's done scrolling, it would be perfectly aligned? The best example I can give is how it behaves in Excel. Provided you have the scroll lines to be set to 1 line in settings, scrolling up or down will move one row at a time. Clicking the empty part of the scroll bar moves down exactly to the next not-fully-visible row.
My research, up until now, indicates I'll be using the .scroll() function (at least if I'm using jQuery), but I'm completely stumped at the plan of attack, even moreso because I'm unable to find any way to differentiate between a mouse wheel scroll, button scroll, or scrollbar jump (or whatever the terms would be).
Is there also a way to restrict this in CSS, avoiding any JavaScript at all?
To achieve this, you need to use scroll-snap-type, as stated by DM in the comments.
You'd set the parent div to have scroll-snap-type: y mandatory;, and it's immediate children elements would have scroll-snap-align: top (or bottom)! This should allow rows to be viewed perfectly, provided the containing element is an appropriate size (and assuming each child element is a known fixed size).
I have a requirement to add a scroll bar that is always visible and which can be directly used by mouse or touch to scroll the contents of a large ListView.
The normal way of scrolling on mobile devices is by swiping up or down. During the scroll process there will be a small scrollbar visible but that scrollbar disappears and even while visible it can't be used to do any actual scrolling.
After much searching I could not find what I needed.
So my question is: Is there a way to make the scrollbar in the ListView fully usable or should I disable it and create a separate scrollbar which I will need to keep in sync. If so how?
For a functional example of something I would be working with see: https://fiddle.sencha.com/#fiddle/124j
I am facing some issues with the jQuery Chosen plugin. Here are some screenshots:
The focused Users input is a jQuery Chosen select input within a tab in a Bootstrap dialog (but this doesn't matter anyway). As you can see the scroll of the Chosen's ul.chosen-results didn't reach the bottom here.
Now if I scroll down the results:
I reach the bottom of ul.chosen-results, but if scroll with the mouse wheel down further from this point on, the rightmost scroll doesn't scroll down.
But I would like the other scroll to go down too from that point on while scrolling down ul.chosen-results with the bottom scroll of ul.chosen-results reached, to achieve this:
See that the rightmost scrollbar is down here too. This is what I want to reach while scrolling on ul.chosen-results. Does Chosen somehow inhibit the scroll event propagation when scrolling ul.chosen-results?
Can I achieve what I want? How?
Thanks for the attention!
In the not minified js plugin file
find following code
high_top = this.result_highlight.position().top + this.search_results.scrollTop();
and replace it by this.
high_top = this.result_highlight.position().top;
This issues has been addressed here another possible fix is to update to jQuery 2.2.1
Here is my scenario I have a web page which will navigate through using mousewheel and scrollbar. I have fixed the mousewheel problem.... But the problem where I use the scrollbar it will navigate to the end or go to the first it depending on the scrollbar you pressed up or down.
I know the error is $(window).scroll(function) here due I navigate from Div 1 to Div 2 which will fire the event a lot of times when the scroll bar moving.
Here is my fiddle
The problem is where i when i scroll using the bar beside down or up. It will trigger until the end of my onscroll event.
Is it possible when i press the scrollbar once only trigger once ?
An alternative way i know is hide the scrollbar and design a fixed position button up and down will resolve this problem but is it possible to do this with default scrollbar/overflow ?
Tried your fiddle. When using mouse wheel, it kept pending between headers 4 and 3 after I reached the 4th one. When I removed the $(window).scroll() function, it worked perfectly, both down and up.
The scrollbar, however, is quite a complicated issue - when you click/tap and drag, you simply can't "steal" the scrollbar from your pointer/finger - the user keeps dragging, yet you're trying to reposition the scrollbar/content forcibly. I don't think this is a good idea (from the UX point of view).
Not sure if it fits your requirements but in case I'd want to fully control the content, I'd completely remove the scrollbar in CSS and then use the mousewheel or swipe functions to control it.
I have content in a horizontal div that exceeds the page area so that to see all of it you have to scroll horizontally. Fine with a trackpad but for those who don't have one I want to make this obvious with the use of either scrollbars or mouseover text/image.
After hours of experiments I finally found this code - scrolling a div of images horizontally with controls - which is perfect(just changed it to mouseover).
The only problem is I want to do it smoothly and without having to repeat the mouseover or clicking.
Also I want to avoid Jquery and all that sliders stuff. I'm a very new to JS and want to keep things simple. Also I wasn't able to force a scrollbar with any CSS solutions.
Thank you
