Figure out if web page is the only tab in a window? - javascript

Is there a way to figure out if the tab your web page is running in, is the only tab in the window or not? I've been looking on google for about 20 mins now and couldnt find anything even similar to this. I'd prefer to do it without any add-ons/plugins/etc. but if i have to use a plugin the only one I can use is Java.

There's absolutely no way to do this, in any browser. Which other tabs are open or not is outside your web page's control.

Browser Like Tabs for an iFrame web browser

I am developing a fun little project which is an iframe browser. The browser functions very well but the problem is, I can't seem to get tabs correctly. What I want for tabs is a remove and add function.
Will someone kindly help me out.
By the way my project can be found here: https://bird-pack.ml/lol/

Cocoa: WKWebView / WebView cannot open links inside Gmail or Inbox

I am the developer of Boxy, a famous native wrapper around Inbox by Gmail, and wanted to ask if anyone is able to help with something I have been struggling with since day one of development.
Here is the problem: links on inbox.google.com and gmail.com work differently than on other sites: clicking on them does not trigger a navigation action on my webview (I am using a WKWebView specifically, but the problem is also present using the old WebView). So I am having a difficult time opening links in an external browser when appropriate.
Because of this, at the time of this writing, I am relying on a terrible hack in order to open links: intercepting clicks on the document.body with javascript (using an event listener) and then forcing them to open on the external browser by calling the native app.
My best guess is that the Gmail/Inbox apps perform some javascript magic in order to track clicks on all the links inside emails and that, somehow, this interfers with the standard behaviour.
Has anyone got any idea how I can solve this problem?
Things I already tried
Implementing the method -webView:createWebViewWithConfiguration:forNavigationAction:windowFeatures: of WKUIDelegate. Did not work: the method is called but the request associated with the navigation action is empty.
I found a solution. This issue is due to when clicking link, instead of opening using target=_blank, Gmail attempts to open an about:blank window and then run javascript to redirect the link.
You need to make sure that Gmail can correctly receive the handle of the created window.
- (WKWebView *)webView:(WebUI *)webView
createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration
forNavigationAction:(WKNavigationAction *)navigationAction
windowFeatures:(WKWindowFeatures *)windowFeatures
You need to make sure this delegate method correctly returns the newly created wkwebview.

Force console to be open on load within iframe - chrome

I am trying to create some simple tutorials, which involve people using the console in chrome. Ideally I would like to build them in a codecademy style - so instead of saying 'browse to this element in the console' and the user having to go to a separate demo page and do this, it would be built into one page.
So, I would have the tutorial, and then an iframe containing the demo page. I need the console to be open in the iframe page (and stay contained within it), but still be usable.
I know in chrome you can change which iframe you are viewing in the dev tools, and if needs be I will simply instruct users to do that, but I feel it would be more effective / smoother if the console was actually within the iframe and was automatically there.
Is there any way to do this?
Thanks in advance.

How to ink to another .html page within Chrome extension/app?

I am building a chrome app for a client that will run in kiosk mode to display in their stores. Right now I have an index.html page that links to about 30 other pages. However, when I click on a link in the app I get an error...
Can't open same-window link to "chrome-extension://leghflngpfmomcflabikghiemaajadne/poweredge"; try target="_blank".
So I tried target="_blank" and that tries to open it in a new chrome window.. no good. I've been reading a little bit about using webview and sandboxing pages but they both open the pages in a new window and it just doesn't look good.
Is there a better way to do this? Right now my only idea is to place all of the content on the index.html page and turn on/off sections of the content with jQuery. I'd love to keep all of the pages separate though, just for my own sanity.
Thanks!
Navigation is disabled for the Chrome Apps platform. In theory you are supposed to make single-page apps - so your turn on/off approach is the "intended" one.
No-one stops you from having several windows though - suppose you have an options page, it wouldn't be strange to open it separately (via chrome.app.window.create)
As stdob mentions in comments, a workaround may be possible by using <webview> with a partition blessed to show local resources. It's not clear though if it will allow access to apps APIs.

How can I stop google.com from pulling my cursor away from the URL with Greasemonkey (or Adblock)?

How can I stop google.com from pulling my cursor away from the URL and focusing it on the search box with Greasemonkey?
I use google as my home page and hit the home button to open a new tab, maybe not the best way to do it, but it is habit. I will start typing in a URL and when the page is done loading the Google search field pulls my cursor away when I'm half done typing.
I know a decent amount of javascript but I don't even know where to start when viewing Googles page source. If someone could write a script for this I would love you forever, and I'm sure many others would too!
EDIT:
Possibly the better question is how to do this with Adblock Plus?
EDIT#2:
Is it possible to run javascript before a specific page loads with a firefox plugin? Or, is it possible to block javascript on a page before it loads?
I am not looking for any "work arounds" I am looking for a fix. A fix to remove or disable "document.f.q.focus()".
Edit#3: What about a bookmarklet? Could it be possible with that?
See http://noscript.net/
It's a firefox plugin that disables javascript on sites. You could configure it to just run on google.com, I think (if you do not want it to interfere with other sites).
Noscript is more secure, but it can be a pain because it uses a whitelist approach.
Or you can use YesScript, which operates a blacklist instead.
Re: "I just want to blacklist a specific line of code on 1 site"...
There is no addon to do that. You can block all scripts from a site using NoScript or YesScript. Or you can block a specific JS file using Adblock.
You cannot selectively block bits of JS that are embedded in the main page, except in rare occasions GM can sometimes work around it.
This sounds like trying to use an anvil to smash an ant. Or some other, better, complex-tool-for-simple-job analogy. I would suggest either setting your home page to a blank page, or opening new tabs with a new tab button or Ctrl+T.
I do not believe it is possible, just looking around a bit. The focus actually comes from the onload attribute of the body element:
onload="document.f.q.focus();if(document.images)new Image().src='/images/srpr/nav_logo27.png'"
As you can see, document.f.q.focus() is your issue. However, I can't get a GM script to run before that onload is executed. I'm not too experienced with that particular issue, though: any GM scripts I've written are novelties whose load order doesn't matter a great deal, so long as it's done after the page is loaded.
If you know how to make GM scripts run before an onload (on a very light webpage), then it's as simple as saying unsafeWindow.document.body.onload = null.
You cannot do this with Greasemonkey, because GM cannot manipulate chrome elements enough to set focus to the address bar.
You cannot do this with Adblock for the same reason, and because Adblock just stops external elements from loading.
None of the FF scripting add-ons could do this either, as far as I can tell.
You could write an extension/add-on to reset focus, but the real problem here is that the user is ignoring the tools in place for the job.
As Scott Cranfill said, use Ctrl T to open a new tab.
If a button is absolutely desired, Firefox already provides one. Do this:
In the Firefox menu, select View --> Toolbars --> Customize... .
Find the "New Tab" icon and drag it to your toolbar.
Click that icon, from now on, when you want a new blank tab.
Done!
