I'm creating a chrome packaged app, and I need to navigate my htmls without creating a lot of windows, like, if the user click one button, it opens the html in the same window the user are.
Is it even possible? If not, is there a way to make windows modal? So the user can't focus another window without closing the current?
Packaged apps intentionally do not support navigation. Apps are not in a browser, there is no concept of forward, back, or reload. Applications which do require the concept of navigation, or modal dialogs, should use a user interface framework that supports that functionality. In fundamentals, you can navigate by manipulating the DOM or by using CSS to animate and control visibility of components of your app.
The page you want to navigate to can be opened in a new window, then the previous page can be closed.
function navigateToLink (link) {
var current = chrome.app.window.current();
chrome.app.window.create(link);
current.close();
}

I have been using Clojure, ClojureScript, lein, shadow-cljs, re-frame, reagent, Emacs, and CIDER to work on a Clojure/ClojureScript dynamic web app project.
Usually, I build the project by executing the command cider-jack-in-cljs in Emacs, choosing shadow-cljs, then shadow for REPL type, and, finally, app for the building option.
The application loads in localhost:3005 with a debugging dashboard. Apparently, this UI is called "re-frame-10x":
After clicking on the up-right arrow icon on the top-right:
I managed to pop out the debugging dashboard into a new window in Google Chrome. It was injecting some CSS and hiding a button on the webpage. Hence, I decided to "remove it" by popping-it out.
But, I would like to move it back to the browser tab that has localhost on the address. How to do it?
As suggested by #eugene-pakhomov, it was just closing that window. I must highlight that I had tried that before, the only problem was that there were multiple windows of that type. And all of them need to be closed for the process to work!
Not sure why the program opens multiple windows...
I have a web application using Primefaces 8.0 and JSF 2.2 and the way I have users navigate to instances of the application is by an HTML page with links like the following:
Always opens in the same window
This makes sure that if the user clicks the link a second time, it simply navigates to the tab they already have open. But the browser(chromium in this case) also forces a refresh of the tab every time this link is clicked! Is there any way to avoid this forced refresh?
My web application is mimicing the UI of my desktop application, flow is as follows
Select Task in browser window
Change any Options and then start
Show Progress in same browser window, the progress bar goess back to server every 5 seconds checking progress.
When task has completed we show report in new tab
and go back to Select task Window,
this is done by running following Javascript in progress page
window.open('/start','_self'); window.open('/reporturl','_blank');
This works fine on my PC but when trying on Safari on OSX and on Android phone and iPad one of two things happen
The progress page becomes the start page but the report page is not opened in tab
The Progress page becomes the report page
My question is does opening window in new tab with _blank have all the problems of using popup windows. If so should I modify my prcoess so that at stage 3 it just displays report page, and then add a back button or navigable footer to the report to allow user to get back to start page ?
I can think of some options you could use instead of new tab.
Modal with Ajax
-- With jQuery it is posible to open modal
dialogs they can be populated with html (or other data) fetched with ajax (async). I am a big fan of these and use them all over my projects. Users will not be annoyed with pop-up warning messages, etc. Once the content is read (or whatever) the user can simply close the dialog. (If I had to make your app I would certainly implement this).
Besides the jQuery dialogs, other modal/dialog scripts are out there. Check out Bootstrap Modal if you like it modern.
Serve report as download
-- Depending on what the user can/will do with the report, it might be interesting to write the report page in a way that it sends back a .pdf file, or another type of file, as download. Loading the URL in a new tab will now always start a download. Triggering this from JS without user interaction might be a problem though (same as with pop-up / new tab). Adding a button to trigger the download on complete will solve this.
I know the question was about the use of tabs.. But try to avoid it. Browsers handle it all in their own way. And many users get confused when suddenly stuff is opening in tabs when they did not ask for it. In case of pop-ups, it is possible for users to turn them of or convert into opening a new tab from within the browser settings. If they have been fiddling with browser defaults, you'll have troubles of keeping the 'flow' of the app the same for all users (and cross browser).
I'm trying to make an extension that will collect some data from currently opened tab on Google chrome.
I also use a popup in my extension to provide a control interface (buttons and stuff).
I need to be able to do the following:
1) Read source code of currently opened tab.
2) To be able to scroll down window content (using the code of course) .
If I could only get access to a javascript "window" object of currently opened tab , that would be enough.
But I'm open for another suggestions .
Can anyone help ?
You can simple use document in a content_script. Content scripts are defined in the manifest.json. In your case you should set "run_at": "document_end", so the dom is fully loaded when your script is called.
For more informations about content scripts and chrome extension development you find an easy to use guide from google - http://code.google.com/chrome/extensions/content_scripts.html
Code from popup won't be able to access directly to window objects from displayed tabs. You have to use a content script which will be able to send the source code of opened tab to the background page. This content script will also be able to scroll the window of opened tab.
I am developing a chrome extension. I am able to pass a message from background page to popup extension when a context menu is clicked if i open the popup page with "Inspect pop-up" selection. Because it stays open in this way.
But if I click the context menu when the popup page is not opened, no message received by it.
Do you have any suggestions to open popup automatically, make it stay open or send message to it when even if it is not active.
There is no way to pragmatically open a popup window. Popup windows are only active when the popup is open which is why you cant send messages to it when it is closed.
You could either queue messages in the background page and have them retrieved the next time the popup window is opened. Or depending on the functionality you might look into using HTML5 desktop notifications instead.
Instead of sending stuff to the popup, the popup should request what it needs when it is opened.
Because the popup is just an HTML page, it doesn't exist until it has been opened.
Basically, like abraham mentioned, you would store any information in the background, using localStorage or chrome.storage. When the popup opens, it should then use the chrome.extension.getBackgroundPage() function to get a reference to the background, which can provide access to the stored information.
If you are using localStorage or chrome.storage, you may be able to access it directly, without using the background, as storage is shared across the whole extension.
