So I have an iFrame displaying a Facebook page and I am trying to enable the native 'bounce' type scrolling however can't get anything to work.
I have tried this:
iframe {
overflow-y: scroll !important;
-webkit-overflow-scrolling: touch !important;
}
But have had no luck so far - tested on both simulator and real iOS device.
Any ideas?
I faced the same problem when our team built epub3 reader app on iOS.
Followed EpubJS v0.3 example, we could handle the problem.
Here is an example:
<div style="width:320px;height:570px;-webkit-overflow-scrolling:touch;overflow-y:scroll;">
<iframe scrolling="no" src="..." style="width:320px;height:8071px;"></iframe>
</div>
Note: you have to calculate iFrame height and set the CSS style (ex: 8071px). Using javascript, you can use
iframe.contentDocument.body.scrollHeight
You may ask me why we have to set height style. Followed some suggestions does not help us to handle handle dynamic content problem (you can see the problem here). By setting height, we can dynamically add or remove highlight texts of users.
Hope that helps,
This would be my approach...
Step 1. Increasing the size of the iframe until the scrollbars dissappear, like this: http://davidjbradshaw.github.io/iframe-resizer/
Step 2. Use David Walsh his trick with a parent div that scrolls the iframe: https://davidwalsh.name/scroll-iframes-ios
But I think it will fail, because of the lack of authentication for cross domain iFrames.
UPDATE: What if you would enlarge the iframe based on the scroll position of the parent div? So parent div scrolls 100px and you make the iframe 100px larger... (given the fact that the iframe has infinite height and assuming its scrollbar is hidden)
I have implemented a fixed header in jQuery Mobile, and it's working great for the most part. When I scroll, the toolbar remains visible. When I tap the screen, the header does not disappear. Great. The only annoyance I see is that when you tap into an input field that's towards the bottom of the page, the header then reverts to position:static so it disappears. You can see that by scrolling back up to the top. Once you unfocus the input box (hit done on the keyboard), then it goes back to position:fixed. I would like it to always be visible no matter what.
<div data-role="header" data-position="fixed">
I'm using jQM 1.4.0 RC1 and in the change log it states:
- Fixed Toolbars are now an extension on the toolbar widget
Sounds relevant, but I'm not sure what exactly that means.
Thanks. :)
This actually a fix for many issues raised on fixedtoolbar widget.
Issue #4410
Issue #4724
jQM hides fixed toolbars once focus is triggered on select, textarea and select; to give more working place when screen width less than 1025.
I have tried the below solution but the results were ugly.
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
$(document).on("mobileinit", function() {
$.mobile.toolbar.prototype.options.hideDuringFocus = "";
});
</script>
<script src="http://code.jquery.com/mobile/1.4.0-rc.1/jquery.mobile-1.4.0-rc.1.min.js"></script>
For more details, check fixedToolbar.js widget on GitHub, go to line 243.

I'm trying to create a simple parallax animation with skrollr: my site is working well on Chrome/Mac but I'm seeing unusual behaviour on the ipad..
On ipad (testing on the IOS simulator),
the main body of the page doesn't skroll at all (or may scroll in the background, underneath the animated div?)
the animated background position (origami pattern) scrolls in the opposite direction (down is up) within the bounds defined in data-start / data-top-bottom
On desktop, the effect I can simulate the effect if I hack the div#hero to be position: fixed; in chrome dev tools.
The skrollr examples work as expected in the IOS simulator.
I have <div id="skrollr-body"></div> just before the closing </body> tag
Any suggestions?
You just naively added an empty #skrollr-body element. The documentation says
Starting with skrollr 0.6.0 there's just one thing you need to do: Include an element on your page with the id skrollr-body. That's the element we move in order to fake scrolling.
If that's the element we move for fake scrolling, then all your elements need to be inside of it (unless they're fixed positioned).
The only case were you don't need a #skrollr-body is when using position:fixed exlusively. In fact the skrollr website doesn't include a #skrollr-body element. If you need both fixed and non-fixed (i.e. static) elements, put the static ones inside the #skrollr-body element.
https://github.com/Prinzhorn/skrollr#what-you-need-in-order-to-support-mobile-browsers
So in other words, simply add a <div id="skrollr-body"> tag right after the opening <body> tag, and close this division by adding a </div> right before the </body> tag.
adding a div wrapper with skrollr-body id did absolutely nothing for, scroll just doesn't work on mobile
How can I make the side panel content scrollable in case there are many items, without scrolling the content on the main page (in JQM 1.3 Beta)? I am trying to implement this for an application running on both Desktop and Mobile browsers.Have looked everywhere, but cannot find the answer.
I've made a div inside the panel that is scrollable, but this doesn't work on iOS4 and below without 2-finger scrolling (div within div issue in iOS).
Please, visit the following to find the answer to the above question:
JQM 1.3 panel + iscrollview + dynamically loaded
http://forum.jquery.com/topic/jqm-1-3-panel-iscrollview-dynamically-loaded-pages
jquery-mobile-iscrollview
https://github.com/watusi/jquery-mobile-iscrollview
.ui-panel-inner .ui-content myElement {
overflow: scroll;
-webkit-overflow-scrolling: touch;
}
You can make the selector more specific to a given element or just leave the "ui-panel-inner" if you want the whole side panel to be scrollable.
Note: The "-webkit-overflow-scrolling: touch" adds native inertia scrolling to the overflow and is not needed if all you want is scroll functionality. This should work on webkit browsers; mobile safari and chrome. But I have only tested it on mobile safari. It will not work on mobile IE but again, I have not tested it.
when using [-webkit-overflow-scrolling: touch;], the scrolling area does work well,
but it causes touch events stopping work out of the scrolling area.
Is there anyone had the same problem? Who can give me some official links about this new scrolling feature?

2011-12-27: I have fixed this problem but I still no wonder the real reason.
In my case, I have several sections in one web page, each section has a scroll area and a header, each time only one section is showed and use css3 animation combined with transform to switch sections. when add [-webkit-overflow-scrolling] in the scroll area of all sections, touch events stop working randomly, so I just add [-webkit-overflow-scrolling] in the section which is showed currently and remove it when the section is hidden. That works well but I still don't know what causes this problem.
I have the same issue, and I can also replicate it every time. I have a page that resizes elements to fit the screen when the orientation of the iPad changes. If at any point the element no longer needs to scroll, it will stop doing so thereafter even if the element is resized back to where it needs to scroll (e.g. flipping back to landscape for me). So it's definitely a bug, but I do have a workaround:
When resizing the element, I'm resetting the -webkit-overflow-scrolling to auto, then setting it back to touch. However, you have to introduce a delay between the two (50ms is working fine, didn't try any lower). So what I did was added an attribute of "scrollable" to the elements, and used the code below (using jQuery):
$("[scrollable]").css("-webkit-overflow-scrolling", "auto");
window.setTimeout(function () { $("[scrollable]").css("-webkit-overflow-scrolling", "touch") }, 100);
Hope this helps!
This is caused by having an <iframe> on the page. Many scripts create <iframes> to do their work including social tracking buttons (Facebook, Twitter, G+), analytics tracking (Google, etc.), and libraries like PhoneGap.
It doesn't matter how the <iframe> is displayed. display: none; visibility: hidden; width: 0; height: 0 does not fix it. If an <iframe> is on the page it will happen, sometimes intermittently and sometimes always.
The only solution I've found so far (which is turning out to not be very workable in a production app) is to delete all <iframes> on the page, create them only when needed (for example, when I need to call a PhoneGap API), and then delete them when finished.
I confirm I saw the same issue on a web app using extensively touch events and list scrolls.
Before iOS5 I was using iScroll, and everything was working fine;
With iOS5, I used -webkit-overflow-scrolling:touch to scroll lists to get faster scrolls.
The consequence is I met random occurrences of touch events no more working on various parts of the app. The issues generally occur after I scrolled a list. it affects randomly elements outside the scrolled area, typically a footer menu.
Reloading the app when in 'frozen touch' state doesn't unfreezes it : to unfreeze it, I had to close the safari tab, open a new one and reload, until I met again the issue while using the app.
The issue is seen on iPad2, iPhone 4, iPhone 3GS, all on iOS 5.0
Eventually, I deactivated the overflow touch scroll and came back to iScroll, and things work well as in iOS4 .
-webkit-overflow-scrolling + CSS3 Animations + Phonegap API calls = touch stops responding.
My phonegap app will work fine until I make a call to a Phonegap API, at which point the touch will stop responding on mainly the first element that has a event attached to it in the current view. A view for my app is body > div.current with the rest of the divs display none.
I can replicate this every time.
It is clearly a bug in iOS5.
Here's a variation on a few of the answers already listed.
My specific issue was that reorientation caused scrolling to stop working completely when -webkit-overflow-scrolling: touch was applied to an element.
Example: Landscape orientation is shorter and needs a scrollbar. Portrait is tall enough that no scrollbar is needed. Reorient to landscape; scrollbar is present but non-functional.
listen for the orientationchange event
do something which triggers a layout change on the scrolling element
ensure that the change is significant enough that the rendering engine doesn't optimize it away. For example, hiding then immediately showing does not seem to do anything. Anything that uses setTimeout() seems to work (perhaps it is the different execution context, I don't know).
Fading in and out works, or hiding and then showing with a short delay works (though it flashes). #Sari's solution for changing the scroll properties works and does not cause any visible redraw.
$(window).on("orientationchange", function () {
// use any valid jQuery selector
var elements = $("[data-touchfix=true]");
elements.css("-webkit-overflow-scrolling", "auto");
window.setTimeout(function () {
elements.css("-webkit-overflow-scrolling", "touch");
}, 100);
});
Note that I haven't tested this fix beyond my iPad 3 other than to ensure that it doesn't cause script errors in Chrome or IE 7/8/9.
In case this is of any use...Incorporating PhoneGap I was using Zepto to append ajax-loaded, scrollable content into the dom. I was then applying a css transition on it. There were no iFrames on the page.
I was experiencing the same issue as mentioned here, where scrolling would just stop working. When I copied the generated code into a separate file and tried that on the iOS simulator - everything worked as expected.
I eventually got it to work by querying the height of the parent container - just before the css transition. By adding var whatever = $('#container').height(); the scrolling worked.
To improve a little bit ThinkingStiff's excelent answer, you can avoid blinking
- if overflow:hidden is set
- if instead of 'auto' value just remove property:
$('.scroll').css({'overflow':'hidden','-webkit-overflow-scrolling':''});
window.setTimeout(function () { $('.scroll').css({'overflow':'auto','-webkit-overflow-scrolling':'touch'})},50);
