The issue is that you can't scroll vertically on the page as the screen jumps around back and forth while you try. Sometimes you can scroll slowly down the page, but eventually the screen gets stuck in a loop and the page jumps back and forth just a small amout vertically. Only certain ones that come from a specific source. Or could it at all be related to the modal swipe down functionality in iOS 13? Any other suggestions?

Looks like we found the root cause somewhat. Still a bit more to fully understand it, but setting certain CSS values from javascript was causing the page to resize. This caused a continuous loop to happen which resulted in the scroll offset getting changed over and over again. AKA: Page jumps up and down. But I suspect this is a low likelyhood to happen to others. Anyway, we found a workaround so moving on to other issues.

I tried applying the sollutions it still did not work for us.

The issue is that I develop a web-service that should be embeddable with iframe. Like youtube, gmap and any others.

Hi David, Thank you very much. I already wasted my two hours to find that popup iframe scrolling is not working on iphone. Very nice clue by you. Hi Hardeep. I am using WP Woocommerce to create the pages.

These pages are loaded into an iframe which dot not scroll very well with an IOS environment Could you please let me know in which page and where you added the code? Thank you so much in advance. It works, but when I try to obtain window. Is there a way to fix it I want to download additional content when user scrolls to the bottom of the page?

On your demo page the iframe is indeed scrollable, and it is the height of the full content of the page within the iframe. However, the contents of the iframe below the first paragraph are not rendered at all on my ipad or in the iOS emulator. Update: This information is still correct. But the content being clipped is a new problem. The problem can be fixed if you control the page being loaded by the iframe. Does anyone know where to fix this in wordpress?

Thank you David.

In certain situations with the iOS For example, having a scrollable ion-list on a child page behind a LoadingController and navigating to it from the first page of the application see the example application further down.

This scroll "freeze" persists until some other change is made to the DOM - even simply changing a CSS attribute on related scrolling elements in the Safari Webview Inspector can trigger the scrolling to work again. Scrolling should work appropriately when navigating from one page to another. In the sample application, scrolling should be enabled and working after being transitioned to the "child" page and once the LoadingController is dismissed.

Important Note : You will need a device running the iOS Steps Listed in the Repo. Seems like scrolling breaks in It unfreezes if you update any CSS property on the element. EDIT for clarity: the bug is that pointer-events: none is added and then removed, but scrolling remains frozen.

I'm going to add another issue that was picked up by one our testers as it may be linked. We have a feature that opens an external site in an inappbrowser and then returns back to the application. We started with the Ionic side menu starter and according to the testers the menu intermittently stops responding to the press to open it ie the menu does not slide open when we get focus back from the inappbrowser.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Safari for iOS doesn't follow the standards. The problem with this is that you can't center UI elements on the screen like modals, or use position:fixed; for say a top menu bar. You may think that you should be able to solve this using Javascript but you can't. There is no way of knowing where the center or top positions are relatively speaking.

Now position:fixed; and position:absolute; will work as expected inside the frame. I have not fiddled much with Javascript on this particular problem, but it should be easy to get real coordinates. You can see the quick and dirty demo here. Tap on the lorem ipsum text to show an overlay that works as expected and occupies the whole viewport. There's a small white square that proves where the overlay ends. As a bonus the code also shows how to block scroll on the underlying content while the overlay is shown.

I have previously used the Embed method which works fine on desktop, but it does not appear on iOS mobile devices. After searching through the forum, I found the suggestion of using iFrame embed method in my web design software - Adobe Muse. The form appears but it always scroll to the top when I try to scroll down. You can take a look at the issue by loading the link below on an iPad. The only way you can scroll down is scrolling close the right side of the screen, which is counter-intuitive for a mobile device.

I tested your form on a iOS emulator and I was able to see the issue you were referring to. The form keeps scrolling to the top when I try to scroll down.

Can you please try adding the? You can use the iframe code below where I have added the? I'm not sure if this will work since I don't have an iPad. But can you try removingthis attribute on your iframe code and see if it fixes your problem:. Everytime when i scroll down by taping the side of the page, where the form not is, i can scroll done without any problems, but once i tap on the form and fields the page move up to start.

Please advise. It seems really confusing that an iframe should behave differently from a scrollable div in this regard, and that iOS would be different from desktop Safari. Ultimately he ends up having to use a dummy DIV and getBoundlingClientRect in order to detect the scroll position of the iframe, yuck! This was done to avoid the user getting trapped in a hierarchy of scrollable regions, which was thought to give a bad user experience on a small screen.

It may be time to reconsider this approach. I second that! I can see how this would be a problem with legacy sites overusing some of these tools like IFrames. But I think that time is gone or at least developers should be able to override this.

It's really a pain in that on iOS only the iframe changes its size, while it does not on other platforms. However, it's not enough to make scrolling work I'm still investigating this In particular, we have an issue similar to bug Simon, Zalan: This was really an experimental patch to avoid flattening and be able to test a bit things. I think it would be good to agree on how to provide this non-flattening option to Web developers.

Is the suggestion of comment 5 enough? Any other idea? Scrolling with touch events does not work at the moment with iframes even with that patch. Should we add such mechanism for iframes too?

No, it's much too late to use the viewport tag as a key to not frame flatten.

I think the best course of action would be to make iframes fast-scrollable on Mac first, to set up that infrastructure. Yes, that more or less matches my understanding after a first investigation of the code. Or re-using an existing one? I see. Simon, I know we chatted briefly in Tokyo about this, but I'm curious to better understand your thinking here. Why is this a greater usability risk than supporting overflow:scroll divs?

As I mentioned, I don't think I've ever heard a single user complain in Chrome about getting stuck in an iframe scroll chain. We do occasionally hear complaints of users getting stuck in regions that cancel all the touch events eg.

Certainly nested scrollers are generally a bad UX paradigm, but virtually all mobile-optimized sites already avoid them, as do many desktop sites using scrollable iframes eg.Suppose you are building something that pops a modal window from time to time. This probably works well in most places, the problem is, on iOS, even if you toggle:. One solution is to write the window. You can get a similar effect by setting the body and html to position: fixed when you expose the modal and ditch the JavaScript there.

It would be nice if we had something better. My esteemed colleague, Tom suggested making use of touchstart to prevent the default scroll behaviour and while that solved the initial problem being able to scroll past the modal it prevented clicks inside the modal. We can use it like this — at the same time that you invoke a function to make the attribute change or class change that shows the modal, you also do this:. The function receives either true or false and subsequently adds or removes an event listener.

We then need a simple function reference that disables the default behaviour of the touchmove event. I welcome a better approach if anyone knows one? Could you share details about your implementation? How is the dialog positioned in CSS? Is there an overlay? Do you use the standard element and API with polyfill, ofc? This is all well and good until the modal content is taller than the device window height. It prevents the scrolling of content in the modal. I think this is a fantastic solution, but maybe needs a little more expansion to account for this.

Sorry Ben, feel free to delete my comment. Hey, did you find a suitable solution? I ran into something similar about a year ago when I was prototyping to improve the UX of elements on iOS. I did a similar approach once but added one more thing to prevent the jump to top I was using jQueryright before adding the overflow: hidden, I store the scrollTop, the after the overflow, I add the scrollTop to the body.

I also banged my head on this for quite some time, and I tried a LOT not only to prevent scrolling of the content underneath, but also to enable scrolling on the modal at the same time. My solution involves intercepting the touchmove event and cancel it when the modal is scrolled to the top or bottom.

Hi Frank. This is an amazing solution. I am trying to do a similar thing with a modal that has a scrollable text div in it. Thanks for the tip. Works for me…just a little modification to the original solution posted here.

Great Thanks again!! I checked your demo and unfortunately it does not work on Chrome for Android.

Yes the post is about Safari iOSI understand, just thought it might be OK for other people coming here to find out why it does not work there. It does indeed work on FF for Android.

The reason for that is that Chrome treats touch event as passive by default to increase scrolling speed and scrolling tap responseFF for Android does not do this.

On another note, when I checked your site on mobile, in particular the navigation menu, not sure if this is intended the body does scroll up and down upon touch scrolling. Not a major thing though. This leaves the user with no way of seeing what they type to search for. A simple solution to that would be to place the search bar at the top of your navigation menu and possibly have the Twitter, GitHub and RSS links show next to each other on one line instead of in a list under each other.
