I have a requirement wherein I must restrict the user viewing my web page. Users should not be allowed to press Ctrl + Tab before finishing a task in the page.
Is there a way to detect Ctrl + Tab keypress in javascript/jQuery?
This code will detect CTRL+Tab:
$(document).keydown(function(e) {
if (e.ctrlKey && e.which == 9) {
alert("CTRL + TAB Pressed")
}
})
Note however that CTRL+Tab functionality is controlled by the browser and you cannot stop it as this fiddle will demonstrate if you have more than one tab open:
No, you cannot. That is, you can detect the keystroke, but not block the behaviour of toggling tabs. And fortunate too, because websites that do this would make browsing a real pain.
And it would defeat the purpose of a web browser. If you need restrictions like that, don't build a website, but a desktop application. But rather, if you build a browser application, make it smart enough to save its state, so users can come back to a task and finish it later if they have switched to a different tab first.
Check the ctrlKey property on the event in your handler.
$(document).on('keypress','*',function(e){alert(e.ctrlKey);})
You can detect it, but you can't stop it.
