I have an item that can be dragged within a shape. I had been also able to move the item with the arrow keys on the keyboard, using:
$(document).bind('keypress', function(event) {
if(event.which === 63232){ // up arrow key
if(!event.shiftKey) howMuch = -1;
else if(event.shiftKey) howMuch = -10;
moveText(howMuch);
}
});
But, at least in FF, this doesn't work anymore. I alerted out the event that is happening on an arrow press and all four return zero.
How can I detect an arrow key press? Oh yeah...javascript or jQuery.
Thank you for your time, Todd
The keycode you're using is wrong, the up arrow is 38:
$(document).bind('keypress', function(event) {
if (event.which === 38) {
moveText(event.shiftKey ? -10 : -1);
}
});
Arrow keycodes for reference:
To find other keycodes check the example for keyPress() in the API
Isn't it just:
$(document).on('keypress', function(e) { // Note I used .on()
if (e.keyCode == 38) { // I never use .which
howMuch = (e.shiftKey) ? -10 : -1;
}
moveText(howMuch); // never seen this function before, isn't that it?
});
