I have an SVG of the US states, and need anchor links to scroll to the state info on the page below. The anchors work fine on desktop and android, but not on IOS. The state changes to to hover color when clicked and does not link, and the hover color remains.
I found some suggestions to use xlink:href, but that is depreciated. I did try it to see if it worked and it did not. I have also tried some suggestions providing jquery code, but it did not work and also stopped the links from working on desktop.
The SVG is set up with hrefs wrapping each path like this:
<svg viewbox="0 0 959 593"> <a href="#ak"> <path id="AK" ...">
<title>Alaska</title></path></a>
(I've removed the long string of code for the path)
Here is the link to the page with the map. The anchor links work on desktop and android and not IOS:

I have never posted here before, so I apologize if this is not enough info.
This has been resolved. Some of the anchor links on iPhone only seem to work when "a id" is used, and the links from the SVG only work when "a name" is used.
I'm writing an app which uses html5 video elements.
On iOS Safari when using playsinline to ensure the video is treated as an inline element for positioning etc, it works as expected except that the video appears on top of everything. z-index and positioning techniques don't seem to help with this issue. I cannot get anything to appear on top of the video under any circumstances.
On every browser except iOS Safari this seems to work absolutely fine.
For reference, this is an Angular app, and I'm currently testing in Mobile Safari on iOS 11.1.2
Also worth mentioning, the video src will resolve to a local blob url. eg. blob:file:///2afb998a-84e3-4819-8243-5da7d7da3cb6
<video
id="video"
[src]="src"
autoplay="autoplay"
muted="muted"
webkit-playsinline
playsinline>
</video>
I had the same problem. Removing overflow style from parent div of video tag solved it. See Video and z-index inside scaled element: some divs disappear for more information.
I am using my webpage to show a pdf from App_Data.
I using this html:
<iframe src="" id="iframePDF" style="width:100%; height:93%;z-index:1;></iframe>
And javascript
$('#iframePDF').attr("src", responseData.TempPath + "#zoom=100&page=1");
The zoom isn't zooming the page and I cannot scroll.
Is there any workaround for this or a solution?
You might be able to scroll using two fingers, which is not intuitive for the user. You can not make the area scrollable unless you know the size of the content, which you can't, because iOS doesn't tell you.
Sorry, friend, but then you'd have to look into a native or hybrid app like the solutions offered by Cordova (PhoneGap). It doesn't matter if the file is in .NET App_Data or anywhere else online.
The reason why it works in your browser is because it has a built-in file viewer which is loaded when you open the file in a new window.
Wrap the iframe in a width-constrained element of some kind then apply this CSS to that element:
-webkit-overflow-scrolling: touch
I making prototype web app for iPad, and I want to embed google map.
I embedded map with this if frame code from google's tutorial:
<iframe width="720" height="340" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Belgrade,+Serbia&aq=0&sll=37.0625,-95.677068&sspn=38.638819,79.013672&ie=UTF8&hq=&hnear=Belgrade,+City+of+Belgrade,+Central+Serbia,+Serbia&ll=44.809,20.465641&spn=0.022226,0.062571&z=14&output=embed"></iframe>
But, in safari I get map with some withe rectangle: http://cl.ly/2u2G0p1T3x3O1Q1X3A1B
and when I add this web app to my homescreen, I don't get map, I get white div: http://cl.ly/0O3n2c3N3C0C1F2x0l2a
Where is some other way to implement google map on iPad web app? :|
I haven't tried making an app yet but I would probably try using Googles javascript api instead of an iframe. I believe your amount of control is much better with js than with the static version.
In recently testing a web application on Windows/Mac desktop browsers - and then on an iPad I noticed various differences in Safari that I wasn't expecting. Even though the version # is the same.
I'd like to compose a list of those differences (for myself and others) to have as a developer reference.
e.g. in Safari on the iPad
iPad Safari takes full control of Select list/option styling
iPad opens the onscreen keyboard when an input element receives focus, thus inline floating calendar widgets (and the like) may not work as expected (or need to be altered)
iPad Safari doesn't support position:fixed like desktop Safari < iOS 5
iPad Safari (similar to iPhone/iPodTouch Safari) automatically hyperlinks 10 digit numbers to offer phone #/contact options
iPad Safari prompt('long message...','default'); shows only 1 line of the message (though it does provide scrolling of the message
I've heard from others that certain JavaScript doesn't work, etc. etc. but I have yet to fully test it thus I'd be grateful for any discoveries that you may have encountered.
A few more for you:
No Flash
Lousy iFrame support (so facebook like etc. needs a custom implementation for iPad)
Weird caching limitations
HTML textAreas doesn't get a scroll bar (you have to double-finger swipe - which of course, is amazingly intuitive)
In general. Treat it like a scaled up iPhone, not a scaled down Desktop.
I thought this might be useful: Apple's guide to preparing web content for the iPad
Just been caught out by the position:fixed issue my self
Safari on iPad has the same issue with button width/padding as on the iPhone
iPhone <button> padding unchangeable? describes this problem and a solution for removing padding on a button with text, but this does not help you if you want a button to be narrower than the padding itself (e.g. for a button that only has a small icon on it). To do that, I had to surround the button with an outer element with a defined width and overflow: hidden like so:
<span style="border: solid 1px blue; display: block; width: 16px; overflow: hidden">
<button style="-webkit-appearance: none; border-width: 0"> </button>
</span>
(the blue border is to show where the button is, it's not critical to the hack)
jQuery's offset() doesn't work: http://bugs.jquery.com/ticket/6446
It also looks like iPad Safari has issues with elements with overflow:auto; that therefore should show scrollbars (test page with div's and iframe's).
iPad Safari seems to have trouble handling background images in rare cases, showing weird lines of lower lying content.
There's not a lot about this in Google (yet).
iPad browser doesnt support file uploading(even if it supports it will useless as iPad does not have a standard File Browser). The file field appears with a Choose File button grayed out.
Beside doesn't support scrollbar in TextAea, it seems that we can using javascript to make text in TextArea selected automatically too.
This code will only move cursor to the end of text in TextArea.
<div>
<textarea id="text-embed-code" autocapitalize="off" multiline="">
There is a fox running after chrome.
</textarea>
<button onclick="testSelectText(event);">select text</button>
</div>
<script>
function testSelectText(e) {
var box = document.getElementById("text-embed-code");
box.select();
e.preventDefault();
return false;
}
</script>
There appears to be a bug in iPad Safari where a CSS element with both a background image and a background color is rendered with a slight border in the color of the background color. It should fill with the background image all the way to the edge of the rendered element.
I just had the same bug on my site, when trying to view it on an Ipad. The HTML structure is like:
<div class="main"> <!-- background-color: white -->
<div class="left"></div> <!-- background-image: url(some_transparent_png) -->
<div class="content">...</div>
<div class="right"></div> <!-- background-image: url(some_transparent_png) -->
</div>
The left layer uses a background-image, whereas the main layer uses just a background-color. The Ipad view shows a slight border at the edge of the left and right layer.
When i add
-webkit-background-size: 100% 100%;
to the left and right layer, the border disappears.
You can now control the styling of select lists on iOS by resetting it with -webkit-appearance: none;
This rule fixes animation flickering in Safari on iOS devices:
body {-webkit-transform:translate3d(0,0,0);}
There appears to be a bug in iPad Safari where a CSS element with both a background image and a background color is rendered with a slight border in the color of the background color. It should fill with the background image all the way to the edge of the rendered element.
24 bit transparent PNGS ABOVE A CERTAIN FILE SIZE don't render on the iPad2.
I can however get 8 bit ones of the same dimensions to render.
I haven't found out what this maximum file size is in order to get them to render.
I'm currently working on a small responsive web-app which makes heavy use of the iframe youtube api. Apparently the ipad version of safari doesn't support a few html5 methods which I use heavily in this project.
One of them is window.postMessage, which is a way of interacting with scripts on other pages, for example the a script that is used "within" that iframe. Autoplaying videos also doesn't work.
Frame problems. iPad Safari will both hide scrollbars and expand frames to the size of their content.
Changing the frame tag to include scrolling="yes" and noresize="noresize" appears to do nothing.
Some sites look fine on everything, even a Dreamcast browser, but not on iPad. The issue can be fixed using tables and iframes instead of normal framesetting (cols and rows, etc).
I also discovered that contenteditable is not supported in mobile safari, thus using a plain textarea is a better bet. Apple Developer Docs
position: fixed;
Does not work in iOS 4 but does work on iOS 5.
