In our PhoneGap iOS application, we are using the InAppBrowser plugin to display some content, and we need to open a page in Safari from within the InAppBrowser.
How can we have links from within the InAppBrowser open in Safari?
From the phonegap documentation:
Opens a URL in a new InAppBrowser instance, the current browser instance, or the system browser.
var ref = window.open(url, target, options);
ref: Reference to the InAppBrowser window. (InAppBrowser)
url: The URL to load (String). Call encodeURI() on this if the URL contains Unicode characters.
target: The target in which to load the URL, an optional parameter that defaults to _self. (String)
_self: Opens in the Cordova WebView if the URL is in the white list, otherwise it opens in the InAppBrowser.
_blank: Opens in the InAppBrowser.
_system: Opens in the system's web browser.
So to answer your question, use:
window.open(your_url, '_system', opts);
Note that the domain will need to be white-listed.
Update 4/25/2014:
I think I kind of misunderstood the question (thanks to commenter #peteorpeter) -- you want to have some way to click a link in the InAppBrowser and have that open in the system browser (e.g. Mobile Safari on iOS). This is possible, but it will require some forethought and cooperation between the app developer and the person responsible for the links on the page.
When you create an IAB instance, you get a reference to it back:
var ref = window.open('http://foo.com', '_blank', {...});
You can register a few event listeners on that reference:
ref.addEventListener('loadStart', function(event){ ... });
This particular event is fired every time the URL of the IAB changes (e.g. a link is clicked, the server returns a 302, etc...), and you can inspect the new URL.
To break out into the system browser, you need some sort of flag defined in the URL. You could do any number of things, but for this example let's assume there's a systemBrowser flag in the url:
.....html?foo=1&systemBrowser=true
You'll look for that flag in your event handler, and when found, kick out to the system browser:
ref.addEventListener('loadStart', function(event){
if (event.url.indexOf('systemBrowser') > 0){
window.open(event.url, '_system', null);
}
});
Note that this is not the best method for detecting the flag in the url (could lead to false positives, possibly) and I'm pretty sure that PhoneGap whitelist rules will still apply.
Unfortunately target=_system does not work from within the InAppBrowser. (This would work if the link originated in the parent app, though.)
You could add an event listener to the IAB and sniff for a particular url pattern, as you mention in your comments, if that fit your use case.
iab.addEventListener('loadstart', function(event) {
if (event.url.indexOf("openinSafari") != -1) {
window.open(event.url, '_system');
}
}
The 'event' here is not a real browser event - it is a construct of the IAB plugin - and doesn't support event.preventDefault(), so the IAB will also load the url (in addition to Safari). You might try to handle that event within the IAB, with something like:
iab.addEventListener('loadstop', function(event) {
iab.executeScript('functionThatPreventsOpenInSafariLinksFromGoingAnywhere');
}
...which I have not tested.
This message is for clarification:
If you open an another with window.open by catching a link on loadstart, it will kill yor eventhandlers that assigned to first IAB.
For example,
iab = window.open('http://example.com', '_blank', 'location=no,hardwareback=yes,toolbar=no');
iab.addEventListener('loadstop', function(event) {console.log('stop: ' + event.url);});
iab.addEventListener('loaderror', function(event) { console.log('loaderror: ' + event.message); });
iab.addEventListener('loadstart', function(event) {
if (event.url.indexOf("twitter") != -1){
var ref2 = window.open(event.url, '_system', null);
}
});
When the second window.open executed, it will kill all the event listeners that you binded before. Also loadstop event will not be fired after that window.open executed.
I'm finding another way to avoid but nothing found yet..
window.open() doesn't work for me from within an InAppBrowser, whether or not I add a script reference to cordova.js to get support for window.open(...'_system'), so I came up with the following solution which tunnels the "external" URL back to the IAB host through the hashtag so it can be opened there.
Inside the InAppBrowser instance (I'm using AngularJS, but you can replace angular.element with jQuery or $ if you're using jQuery):
angular.element(document).find('a').on('click', function(e) {
var targetUrl = angular.element(this).attr('href');
if(targetUrl.indexOf('http') === 0) {
e.preventDefault();
window.open('#' + targetUrl);
}
});
Note that that's the native window.open above, not cordova.js's window.open. Also, the handler code assumes that all URLs that start with http should be externally loaded. You can change the filter as you like to allow some URLs to be loaded in the IAB and others in Safari.
Then, in the code from the parent that created the InAppBrowser:
inAppBrowser.addEventListener('loadstart', function(e) {
if(e.url.indexOf('#') > 0) {
var tunneledUrl = e.url.substring(e.url.indexOf('#') + 1);
window.open(tunneledUrl, '_system', null);
}
});
With this solution the IAB remains on the original page and doesn't trigger a back-navigation arrow to appear, and the loadstart handler is able to open the requested URL in Safari.
I am running into a pickle. When I view my web app within mobile safari via iOS 6, I am able to successfully open up my basic target links <a href="link.html" target="mainframe"into my retrospective iframe <iframe src="http://www.linkexample.org/" name="mainframe"></iframe>
Though when the app is opened via standalone all the links exit out of the app and into Mobile Safari. You can see a working example at http://lacitilop.com/m2
Anyone have any suggestions on how to fix this?
You'll need to write some javascript to change the src of the iframe.
For a start, get your app working so that links will not open Safari by using something like the following (it's using jquery by the way):
if (window.navigator.standalone) {
$(document).on(
"click",
"a",
function (event) {
event.preventDefault();
var aurl = $(event.target).attr("href");
if (aurl) {
location.href = $(event.target).attr("href");
}
else {
location.href = this;
}
}
);
}
then you'll need to modify it to work with iframes too.
For more iphone app stuff you'll want to look at this:

I didn't find an answer to my question anywhere and I know nothing about javascript, so I can't figure it out myself.
If I have jQuery mobile website built so that every single page is in separate html file (single page template). May I use standard asynchronous Google Analytics code with it, or do I have to make modifications similar to those used in multi page template?
Would be very thankful if someone could answer this question.
Yes, you can use the standard Google Analytics code. You will however, need to "push" certain page views to Google Analytics because of the way jQuery Mobile handles page navigation.
For example, if you have a Contact form on your site at contact.html that, once submitted, goes to a process.php page, and then after completing, the user arrives at thank-you.html, you will need to call some JavaScript to "push" the pageview to Google Analytics.
For example, if your jQuery Mobile page element (data-role="page") has id="thank-you", then I'd use this:
<script type="text/javascript">
$(document).delegate('#thank-you', 'pageshow', function () {
//Your code for each thank you page load here
_gaq.push(['_setAccount', 'UA-XXXXXXX-X']);
_gaq.push(['_trackPageview', '/thank-you.html']);
});
</script>
UPDATE:
I would put this in your script.js file which is included in the head after you load jQuery and jQuery Mobile. This fires on each data-role="page" pageshow event, and is currently working on my live projects just fine.
$('[data-role=page]').live('pageshow', function (event, ui) {
try {
_gaq.push(['_setAccount', 'UA-XXXXXXX-X']);
hash = location.hash;
if (hash) {
_gaq.push(['_trackPageview', hash.substr(1)]);
} else {
_gaq.push(['_trackPageview']);
}
} catch(err) {
}
});
I've used sortable/portlet jquery ui plugin on my website. I load some boxes after the page is loaded via ajax. but they don't look like the boxes appears at the page load time. I know the problem loading via ajax and bind issue. But how can I solve it?
You're ajax call has a success method which you can use to bind to elements that have been dynamically added.
For example you could do
$.ajax({
url: 'ajax/test.html',
success: function(data) {
$('.result').html(data);
$(".column").sortable({ connectWith: ".column", cursor: 'crosshair' });
}
});
I have a list of files and in the end of each li-element I got a button, which looks like
<div class="settingsBtn"></div>
In the dialog I got a form. A want to submit some data and then close dialog. To be honest I think I'm missing something simple, the submit works but I don't want to load any html data on the php side, I just want to close the dialog.
I accomplished this but enable ajaxform plugin and I handle it manually:
$(document).delegate("#myDialog", "pageinit", function() {
$('#myForm').submit(function() {
$(this).ajaxSubmit({
success: function() {
$('.ui-dialog').dialog('close');
}
});
return false;
});
});
But it seems like a wrong solution. I don't have an ajax loader picture, and the jquery mobile framework has everything for ajax handling, but I didn't find how to close the dialog =(
I'd appreciate any help, thanks.
