Is it possible to capture these shortcuts?
I tried this but it doesn't work:
$(window).keydown(function(event) { console.log(event.keyCode); event.preventDefault(); });
When I press T it shows 84
in the console, but if I press Ctrl+T it shows nothing, and opens a new tab.
I would like to capture these shortcuts and prevent any browser action.
In all major Internet browsers (e.g., Chrome, Edge, Firefox, Opera), pressing Ctrl + W closes the current tab. If there aren't multiple tabs open, pressing Ctrl + W closes the browser.
Alternatively referred to as Control+T, ^t, and C-t, Ctrl+T is a keyboard shortcut most often used to open a new tab in an Internet browser.
Open a document. Ctrl+O. Create a new document. Ctrl+N. Save the document.
$(window).keydown(function(event) { if(event.ctrlKey && event.keyCode == 84) { console.log("Hey! Ctrl+T event captured!"); event.preventDefault(); } if(event.ctrlKey && event.keyCode == 83) { console.log("Hey! Ctrl+S event captured!"); event.preventDefault(); } });
(6.0.1 tested)
In Firefox both event listener works. If you press CtrlT or CtrlS keycombinations, you will get both message on the console, and the browser wont open a tab, nor ask for save.
It is intresting that if you use alert
instead of console.log
the event.preventDefault()
not works, and opens a new tab or asks for save. Maybe this bug needs to get fixed.
In Chrome 3 it works like in Firefox.

In Chrome4, certain control key combinations have been reserved for browser usage only and can no longer be intercepted by the client side JavaScript in the web page.
These restrictions did not exist in Chrome3 and are inconsistent with both Firefox3/3.5 and IE7/8 (on Windows).
In Chrome 4 it works similary to Firefox, except some keyboard combination:
CtrlN
CtrlShiftN
CtrlT
CtrlShiftT
CtrlW
CtrlShiftW
These combinations cannot get captured by Javascript, but embed plugins can capture these. For example if you focus in a Youtube video and press CtrlT, the browser won't open a new tab.
It works like in Firefox or Chrome3.
(tested)
IE9 is a black sheep again, because it dosen't allow javascript to capture any Ctrl? keyboard event. I tested with many keyboard combination (R,T,P,S,N,T) and neither worked. Also embed applications can't capture the event. Tested with Youtube videos.
Thanks to @Lime for the great link.
As of March, 20th, 2012, there has been a Chrome fix that allows web applications to handle Control+NWT in Chrome in js keydown event (so it works in pure javascript, or any library like jQuery).
This fix allows javascript to handle this key combinations if Chrome is opened in Application mode, which can be done in this way:
The fix is documented here:
