webappUrlPatterns does not work on multiple "radiofrance" sites

[Nicolas Delvaux]

Hi,

I do not manage to confine my webapp on its site, the "--webappUrlPatterns" just seems to be ignored.
I tested on Ubuntu 15.10 and on Mako (up-to-date rc-proposed).

Test case 1 (working):
Run "webapp-container --webappUrlPatterns=http://foo.org/* http://www.google.com/"
→ As expected, any link clicked on this page is opened in the Web browser (as no URL match the pattern)

Test case 2 (failure):
Run "webapp-container --webappUrlPatterns=http://foo.org/* http://www.fipradio.fr/player"
→ All URLs are opened in the webapp. I can go to twitter, facebook... anywhere.

I have the same issue on other Radio France sites, like:
* http://www.franceculture.fr/
* http://www.mouv.fr/
* http://www.francebleu.fr/

Strangely enough, everything seems to work on:
* http://www.francemusique.fr/
* http://www.franceinter.fr/

If it can help, I noticed strange things on http://www.franceinfo.fr/:
At the bottom of the page, the Twitter, Facebook and Dailymotion links are opened in the webapp whereas the "radiofrance.fr" link is opened in the web browser.

Hmm, looking closer at it it seems all non-working links have the 'target="_blank"' attribute set.
So, is this a feature? Is there anyway to force these links to open in the browser?

[Olivier Tilloy (osomon)]

From the webapp-container code, it seems like handling _blank target links in overlay webviews is the expected behaviour.
Alex, can you comment on this?

[Nicolas Delvaux (malizor)]

If it happens to be a feature, do you know of any way to inject javascript on a page, eg. to remove the _blank targets in question?
I don't think webapp-container is able to do that, but perhaps there is a more advanced container somewhere?

[Alexandre Abreu (abreu-alexandre)]

@Olivier & Nicolas: yes it is the expected behavior, all _blank target (and window.open'd "views") are opened inside the webapp and not dispatched to the default browser,

An option is planned to do the opposite (have external URL open in the webapp):

@Nicolas: you can definitely inject JS code from the container, I'll get back to you with an example,

[Nicolas Delvaux (malizor)]

@Alexandre: If you come by here again, I'm still interested by the way I could inject JS in webapp-container. It would really help if you could point me to a documentation or to an existing app source code :-)
