Thanks, but i know you`re lying. ;-)
It`s not working as expected so far. Maybe someone in this group who
is engaged in the extension system can tell me if it`s just me or if
they had similar problems, or if someone has an idea how to get around
the following things.
1. Using content scripts, eventhandlers seem to be a little unreliable
For the show-the-image-extension i used the "subscribe"-example, where
the find-function is called when the script is intialized and onfocus.
Assuming "onfocus" is on focus of the tab, which sometimes works, but
sometimes not.
2. I think it should be easier to manipulate the DOM from within an
extension.
Instead of the use of a content script to access the contentwindow it
would be more intuitive to be able to use something like
chrome.tabs.getSelected(windowID,function(tab) {
tab.document.getElementByTagName('whatever');
})
directly out of the extension itself.
3. The ability of sending messages between extension and conten
scripts does not work as i expected but i haven`t figured out yet if
this is an issues in the extension or the extension system itself. In
my case i think it would be better to trigger the scan for images or
image links on demand than onload or onfocus but it doesn`t work
properly, especially if you have more than one open tab.
4. I`m missing the possibility to manipulate the DOM before everything
is loaded. Maybe you wanna make an adblock-extension, you can prevent
ads from displaying but it would be better to not even load e.g. to
save bandwidth.
5. I even more miss the ability to save things on the clientside and
to use base authentication in XHR requests, which seems to not work
correctly. I started to make an extension which keeps an eye on my
nagios-monitored systems.
I made an xml file to store the connection-information which i can
read from my extension but i can`t change it from within a gui or
something. So i can check the status if i login once in a session
manually, like in the gmail-check example, can connect to the host,
defined in the preferences.xml, but i dont have the ability to store
this information and log-in automatically from within the extension.
Maybe someone has an idea how to do this.
That was pretty much. Sorry for that.
And i haven`t used my english skills for quite a while. Sorry for that
as well. ;-)
