Thank you for this great script which I have been using since iOS 11.0.
Unfortunately, tonights iOS 11.3 public beta 1 changed something so each link now opens in the in-app browser (it doesn't jump to Safari but adds the in-app location and toolbar on top of the page.
Would there be a solution to solve his?
Many thanks!
@jwronken good to know the script was valuable to you for so much time. Unfortunately I am not supporting any apps currently and I consider my knowledge of the state of the art a bit outdated. Everyone is calling this PWAs now, and I would check with either the HTML5 Boilerplate guys or read a bit of the Chrome Developer Advocate talks. I suspect there are <meta> tags and other modern tech to help you with this in modern browsers. Appreciate if you can post here your findings so the community (people following comments on this gist) can benefit.
Hi Irea
I found indeed the solution...in your index.html (or better said, the initial loading page) include this in the header:
<link rel="manifest" href="manifest.json">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="application-name" content="your app name">
<meta name="apple-mobile-web-app-title" content="shortname">
<meta name="msapplication-starturl" content="index.html">
<script src="compressed.js" type="text/javascript" charset="utf-8"></script>
then create a text file called manifest.json with the following:
{
"name": "your app name",
"short_name": "shortname",
"lang": "en-US",
"start_url": "index.html",
"display": "standalone",
"icons": [
{
"src": "./img/apple-icon-144x144.png"
}
]
}
that's all to get it working, make sure of course path to compressed.js and the images is correct.

thank again @irae for your script!
Hi,
This original script (to the top works well) Thanks. But I need to use it with input file. It's desactive click on input file for now. Any idea to add input file in the scope please ?
hi and thanks for the script . this prevent some of my modals to open . the modal opens and it closes suddenly any idea how to exclude some links and pages from this script ?? or any other way to fix this .
For both @wobility and @farshadff I would like to remember the goal here.
This small script is meant to help a pure HTML website that wants to be added to the iPhone home screen and not show the Safari interface. If the site is purely HTML and CSS, it is where this small script helps the most. Both the file implementation and the modal are application logic that can be considered out of the scope of this small script and maybe the goals here diverge.
For the input file (from @wobility), maybe letting it open in Safari is a good thing, since it shows the "lock" mark to prove you are using SSL and uploading file is secure. When I created this small utility iOS didn't support input type file, so any contributions are welcome.
For the modal (from @farshadff), try e.stopPropagation() in your modal link, without changing the script above. If that's not helping, your site might deserve its own solution instead of the script above.
Yes thanks for your answer. Of course the website is a Webapps in Html / JS / CSS. Your script works fine and it is really cool. I finded a simple tricks to open file input, it's not the best way but I had don't time to find better way. I just add an exception with bollean varaible. I forgot to tell you that I was going through a specific design with an Href link, that's why I had this problem. Otherwise the input file works well.
<a href="#" class="photoUpload" onclick="inputFileLink=true;"> <form method="POST" enctype="multipart/form-data" id="fileProfileUploadForm" action="/user/upload_picture/"> <input type="file" accept="image/*" class="upload" name="fileProfileUpload" id="fileProfileUpload" onchange="$('#fileProfileUploadForm').submit();"> </form> </a>
... if ('href' in noddy && noddy.href.indexOf('http') !== -1 && (noddy.href.indexOf(document.location.host) !== -1 || remotes)) { if(inputFileLink){ inputFileLink = false; }else{ event.preventDefault(); document.location.href = noddy.href; } } ...

Is there anyone that has a working version of this script, I'd love your help/solution being posted here :-)
