I'm using a "Bounce" web page that is linked from a text message to open my app. The "Bounce" web page essentiall does this:
<script type="text/javascript">
window.location.href = "appname://location";
</script>
and works great if the appname:// protocol scheme is registered. But if it is not, an error message is displayed to the user:
Cannot Open Page
Safari cannot open the page because the address is invalid
Any ideas on how to attempt to do this redirect, but not show an error if its not working?
There's only a hacky javascript method to make it 'work', the invalid popup will still appear but will shortly disappear if the app is not installed, and take them to a different url
document.location = "appname://location";
setTimeout(function(){
document.location = "http://google.com";
}, 50);
The new way to do this is apparently Universal Links

I am using Google Tag Manager and it just stopped working on the landing page that client's are redirected to after filling out a form. It works if you refresh the page, but doesn't work on redirects.
I know this smells like turbolinks, so I've modified the javascript function like so many articles have recommended:
<script>
document.addEventListener('turbolinks:load', function(event) {
console.log(event, dataLayer)
var url = event.data.url;
dataLayer.push({
'event':'pageView',
'virtualUrl': url
});
});
(function(w,d,s,l,i){
console.log("getting it")
w[l]=w[l]||[];w[l].push({
'gtm.start': new Date().getTime(),event:'gtm.js'
});
var f=d.getElementsByTagName(s)[0],j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src='https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})
(window,document,'script','dataLayer','GTM-######');
</script>
In my console, I see the console.log(event, dataLayer) but there is no request to: https://www.googletagmanager.com/gtm.js?id=GTM-######
When I refresh the page, I see the same things logged to my console, but there IS a request to https://www.googletagmanager.com/gtm.js?id=GTM-######.
Does anyone know how to make this request fire or understand what might be going wrong?
I would like to build an Firefox extension which after users click it, a web page is dynamically constructed and opened in a new tab.
In "tab" API, I only saw tab.open() open a hyperlink to a remote website. Can I construct a JavaScript variable contains all the HTML contents (Like var page = "blahblah....") and open it? How to do that?
You don't have to dynamically construct it, just put a htm page in your addon and then the link to it will be resource://your addon id/blah.htm. This addon here creates a page: addons.mozilla.org/en-US/firefox/addon/twitch-alarm
You can also create an about:blah url to your page, this shows how to do it without the sdk: github.com/Noitidart/ZooniverseXpert
You don't have to create a html page dynamically but put a html page in your addon and refer it when you open a tab.
tabs.open({
url : self.data.url("js/error.html"),
onReady : function(tab) {
var errorWorker = tab.attach({
contentScriptFile : self.data.url("js/error.js")
});
errorWorker.port.emit("error_page",message);
}
});
Here I am displaying an error page which is stored in my addon and attaching a content script file to dynamically change the contents of html page through message passing between main.js and error page.
Hope it is of some use to you.
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.
In my Grails application, a user can click on a g:link which will call my controller to export certain data to a CSV file. This works with no problems.
I then moved that button to a jQuery dialog box and, when the button is clicked, I use
${remoteFunction(action:'export', onSuccess:'closeMe();', id:courseInstance?.id)}
to call the same controller method and close the dialog box. I've confirmed that the method is actually called, and the dialog box closes. The user is not prompted with the CSV dowmload, however. I'm assuming this has something to do with the remoteFunction, but I'm not really sure. Can anyone explain why this might happen, and a potential fix?
Thanks!
With AJAX requests you can't handle to download content as attachment and so it can't trigger the Save As dialog.
There are a couple of workarounds for this:
Use a plain g:link as before and bind the 'closeMe();' function to the 'click' event. The problem is that you have no control on error or success response.
Use an iframe: You can create a temporary invisible iframe and set its location to the URL of the file to download. It also has the backside of not controlling the success/error response.
The code could be the same as in this answer:
<script type="text/javascript">
function downloadURL(url) {
var iframe;
var hiddenIFrameID = 'hiddenDownloader';
iframe = document.getElementById(hiddenIFrameID);
if (iframe === null) {
iframe = document.createElement('iframe');
iframe.id = hiddenIFrameID;
iframe.style.display = 'none';
document.body.appendChild(iframe);
}
iframe.src = url;
}
</script>
And the link
Export
My main page is here:
http://www.mydomain.com/main/main.php
My login page is here:
http://www.mydomain.com/main/pages/login.php
Main.php uses ajax to fetch data in response to a tap event. This works fine until I navigate to my login page and then back to my main page. After going to the login page and back, the relative paths get messed up such that the ajax looks for server file in the wrong place.
here is the ajax:
1. function get_more_data() {
2. more_data_index += 15;
3. var formData = "index=" + more_data_index;
4. $.ajax({
5. type: "POST",
6. url: "genxml.php", // file located here: http://www.mydomain.com/main/genxml.php
7. cache: false,
8. data: formData,
9. dataType: "xml",
10. success: showFiles3,
11. error: onErrorMoreData
12. });
13. }
After I navigate back to main.php from login.php the ajax tries posting to the wrong location:
http://www.mydomain.com/main/pages/genxml.php
(genxml.php is not in the "pages" subdirectory; it's in the main directory.)
I tried updating the ajax to use an absolute path:
url: "http://www.mydomain.com/main/genxml.php"
This made the post successful, but my data parsing failed because relatives paths are used in the main file for things like images. So instead of getting images from here: http://www.mydomain.com/main/ the script was trying to get images from here: http://www.mydomain.com/main/pages/
I've found a few posts with people having similar issues, but I've not come across a solution. I've also tried reading the jquerymobile docs and it's very possible that the jquery developers attempt to cover this issue here, but I admit I don't completely understand everything on this page:
http://jquerymobile.com/demos/1.0b3/#/demos/1.0b3/docs/pages/page-navmodel.html
If anyone can help I would really appreciate it. Thanks.
P.S. This issue happens on Android and Google Chrome, but not in Firefox.
I have created a working example of what you're trying to do. You should be able to look at this and see what I've done. Be sure to checkout the master.js. I think that the key to making it work in your situation is to nest the ajax calls within the "pageshow" event to be sure that your baseURL has been updated. You can download the example at http://www.roughlybrilliant.com/stackoverflow/7372909.7z
View the example in action as it pulls in weather.xml with relative URLs.
$("div").live("pageshow", function(){
var $page = $(this);
get_more_data();
});
Why don't you use one of this:
use "../main.php" when redirecting back from login page, or
remember UrlRefer from Headers when you entering login.php and use that to redirect back to any previous page with 301
