I have a shortcut key K . It should focus on my input, but I don't want it to insert the letter K
when it focuses.
$(document).keydown(function(event) { if (event.which == 75) { $('input').focus(); } });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <input type="text">
You can use event.preventDefault()
to stop the standard behaviour of the event. Note however that this will stop the letter K
from being able to be typed in the input
. To allow that you need to add a keydown
handler to the input
itself which stops the event propagation reaching the document
. Try this:
$(document).keydown(function(event) { if (event.which == 75) { event.preventDefault(); $('input').focus(); } }); $('input').keydown(function(e) { e.stopPropagation(); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <input type="text">
This is another way:
At the time of keydown, if it is k
and the input does not have focus then prevent the default behavior and give focus to the text field.
$(document).keydown(function(event) { if (event.which == 75 && !$('input').is(":focus")) { event.preventDefault(); $('input').focus(); } });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <input type="text">
If you want to abruptly stop the propagation, you can also use return false;
:
$(document).keydown(function(event) { if (event.which == 75) { $('input').focus(); return false; } }); $('input').keydown(function(e) { e.stopPropagation(); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <input type="text">
var input = $('input');
$(document).on('keyup', function (e) {
if(input.is(':focus')){
return;
}
if (e.which == 75) {
input.focus();
}
});
keyup
event;
