I want to detect the focus event of an element, but only if it was initiated by the user pressing the tab key. For example:
<input type="text" id="foo" />
<input type="text" id="detect" />
If the user is focused on #foo and presses Tab, I want the event to fire once #detect becomes focused (or a conditional inside the focus event to be true). Conversely, if the user simply clicks on the #detect field to focus it, I do not want the event to fire (or I want the conditional inside the focus event call to be false).
I don't want to use the keydown event of #foo and check if the tab key was pressed, as I want the approach to be independent of any other element.
I looked through the console output of the following code, but couldn't notice any real differences between the two methods of focusing:
$('#detect').on('focus', function(e){
console.log(e);
});
(fiddle)
Is this possible to accomplish in a relatively simple way?
Update: change the listener around:
$(window).keyup(function (e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 9 && $('#detect:focus').length) {
alert('I was tabbed!');
}
});
Original: I know you have accepted an answer but you could test the button pressed using the following:
$('#detect').on('focus', function(e){
$(window).keyup(function (e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 9) {
alert('I was tabbed!');
}
});
});
