First and foremost, this has been very helpful so thank you to everyone who contributed!!

This is working great for me on my site on all links except for one:

" http://domain.com/index.php?option=com_community&view=frontpage&Itemid=107 "

I've tried several different things thus far to prevent this link from opening outside of my app but I've had no luck yet.

If anyone can shed light on this I would be very grateful!

Thanks in advance!

I see this is a good four years old now. It doesn't seem to work for me in iOS 8.1+ Can anyone confirm if it works or doesn't for them? I tried setting remotes = TRUE but all href links open in mobile Safari for me.

I have a link with onclick to confirm the action, with OK and CANCEL option. On any desktop browser (Chrome, Safari...) it works properly, but on iOS WebApp (using that script) the CANCEL button do the same function as OK.

Example Link:

<a onclick="return confirm('Really want to proceed?')" href="/reservation/cancel/1">Cancel</a>

Any idea to solve it?

Here is a modification for rails applications wanting their data-remote="true" links to work as well. In coffeescript:

$(document).ready ->
  # For iOS Web apps, so they do not open in new window
  if 'standalone' of window.navigator and window.navigator.standalone
    # If you want to prevent remote links in standalone web apps opening Mobile Safari, change 'remotes' to true
    noddy = undefined
    remotes = false
    document.addEventListener 'click', ((event) ->
      noddy = event.target
      # Bubble up until we hit link or top HTML element. Warning: BODY element is not compulsory so better to stop on HTML
      while noddy.nodeName != 'A' and noddy.nodeName != 'HTML'
        noddy = noddy.parentNode
      if 'href' of noddy and noddy.href.indexOf('http') != -1 and (noddy.href.indexOf(document.location.host) != -1 or remotes)
        event.preventDefault()
        # do not redirect page on data-remote links
        (document.location.href = noddy.href) unless $(noddy).data('remote') == true
      return
    ), false

@karlingen Awesome, also prevents links where turbolinks="false" is set from opening a new window in those mobile Safari standalone Webapps.

Here is my modification for TypeScript application. Note: The solution supports UI Web View case and target=_blank

static getIOSScope(): string {
    const standalone = (window.navigator as any).standalone;
    const userAgent = window.navigator.userAgent.toLowerCase();
    const safari = /safari/.test(userAgent);
    const ios = /iphone|ipod|ipad/.test(userAgent);
    if (ios) {
        if (!standalone && safari) {
            return 'browser';
        } else if (standalone && !safari) {
            return 'standalone';
        } else if (!standalone && !safari) {
            return 'uiwebview';
        }
    }
    return 'another';
}

static fixIOSLinks() {
    const scope = Utils.getIOSScope();
    if (scope !== 'standalone' && scope !== 'uiwebview') {
        return;
    }
    // _blank links open inside
    const links = document.getElementsByTagName('a');
    for (let i = 0; i < links.length; ++i) {
        if (links[i].getAttribute('target') == '_blank') {
            links[i].removeAttribute('target');
            links[i].setAttribute('data-target', '_blank');
        }
    }
    // not _blank links open outside => iOS is piece of shit
    document.addEventListener('click', function (e) {
        let element: Element = e.target as Element;
        while (!/^(a|html)$/i.test(element.nodeName) && element.parentNode) {
            element = element.parentNode as Element;
        }
        if (element.getAttribute) {
            const href = element.getAttribute('href');
            const target = element.getAttribute('data-target');
            if (target) {
                return;
            }
            const protocol = (element as any).protocol;
            const isHrefDefined = !!href && '#' !== href;
            if (isHrefDefined) {
                const isWebProtocol = !protocol || protocol !== 'tel:';
                const isRelativePath = Utils.isRelativePath(href);
                const pattern = new RegExp("^[a-z][a-z0-9+.-]*:\/\/" + window.document.location.host);
                const isCurrentHost = pattern.test(href);
                if (isWebProtocol && (isRelativePath || isCurrentHost)) {
                    e.preventDefault();
                    window.document.location.assign(href);
                }
            }
        }
    }, false);
}

@irae @khovanskiy Is there a way to execute on links that load within AJAX content? For instance: I have a featherlight loading AJAX content. Is there a way to prevent links loaded on AJAX to open pdf or XLSX files within the app?

MovingGifts commented Jun 25, 2018

@khovanskiy I think you forgot to include the Utils.isRelativePath(href)function used in your code snippet:

const isRelativePath = Utils.isRelativePath(href);

Can you please include it to complete the solution you were sharing?

I am trying to find a solution so that i can have it open PDF files or other links open in mobile web browser but all others stay in the PWA. Anyone know how to do this?

I am using the following code

<script>(function(a,b,c){if(c in b&&b[c]){var d,e=a.location,f=/^(a|html)$/i;a.addEventListener("click",function(a){d=a.target;while(!f.test(d.nodeName))d=d.parentNode;"href"in d&&(d.href.indexOf("http")||~d.href.indexOf(e.host))&&(a.preventDefault(),e.href=d.href)},!1)}})(document,window.navigator,"standalone")</script>

@justinputney : Just found this, seems to fix it, you just need a bare bones manifest, though it only works for pages added after the manifest was added to the site : https://stackoverflow.com/questions/58210991/peculiar-pwa-bug-on-safari-ios-13-1-2

correct me if I'm wrong, but to prevent links from opening in safari, isn't just the scope the only thing you need to add to your manifest? No javascript, no hacks no nothing just a single line in the json file.
