I am trying to restrict user to scroll if they touch on an iframe. So, if they touch on body, they can scroll.
Wondering why below code works fine in Mobile Chrome, but not working in Mobile Safari. Any way to fix this for safari?
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<style>
.overflowHidden {
position:relative;
overflow-y:hidden;
}
.overflowAuto {
-webkit-overflow-scrolling: touch;
overflow: auto;
}
</style>
</head>
<body>
<section>
<p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p>
<iframe id="appSimulator" style="background: #000000;" width="189px" height="400px" frameborder="0" scrolling="no"></iframe>
<p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p>
</section>
<script type="text/javascript">
document.body.addEventListener('touchstart', function(){
document.body.style.overflow="auto";
$('body').removeClass('overflowHidden');
$('body').addClass('overflowAuto');
}, false)
document.body.addEventListener('touchend', function(){
document.body.style.overflow="hidden";
$('body').removeClass('overflowAuto');
$('body').addClass('overflowHidden');
}, false)
</script>
</body>
</html>
EDIT
Example for Mobile Chrome - This is what I want in Safari mobile
Thanks.
EDIT 2
Thank you for the help from muecas.
Here is the current result from Safari Mobile
Current Code
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<style>
body {
-webkit-overflow-scrolling: touch;
}
.iframeContainer, iframe {
width: 189px;
height: 405px;
}
.iframeContainer {
overflow: auto;
}
</style>
</head>
<body>
<section>
<p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p>
<div class="iframeContainer">
<iframe id="appSimulator" src="https://appetize.io/embed/keyyyyyyy?device=iphone5s&scale=50&autoplay=false&orientation=portrait&deviceColor=black&language=zh-Hant" frameborder="0" scrolling="no"></iframe>
</div>
<p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p><p>hello</p>
</section>
</body>
</html>
if I set .iframeContainer { overflow: hidden; }
.iframeContainer { overflow: hidden; }
The main problem with Safari iOS is that the iframe
tag is treated as some sort of responsive element, and will act strange to its size, and contained element (loaded HTML) sizes. I tested using an iframe
with real content, so it will be fully scrollable. Using the same code as in you example, Safari iOS showed the iframe
with full height of the contained html content event with a width
and height
defined.
To solve the problem you need to include the iframe
in a block
container, and then set the block container size ( width
and height
) and overflow
to auto
, and add the vendor attribute to the body to allow the iframe
to be scrolled properly. Also, dont forget to set the iframe as scrollable.
You can discard the js
implementation.
I tested this on every desktop browser, Safari iOS and Mobile Chrome.
You may also want to check this link when the responsive content inside an iframe is discussed.
Hope it helps.

It seems touch event works well but overflow is not.
I am not sure what your html looks like, however you can try these:
hidden:
body { /* position can be fixed */ position:relative; overflow-y:hidden; }
auto:
body { -webkit-overflow-scrolling: touch; overflow: auto; }
