what is the key code for shift+tab?
JavascriptHtmlJavascript Problem Overview
I am working on key mapping. The problem is that when I press the TAB button down it navigates to the next input field.
>TAB has key of 9 and
>DOWN has key of 40
But, what is the JavaScript key code to go to the previous input field (SHIFT + TAB)?
What I want is to go to next link; what is keycode or code for the previous link?
Please help. Thanks.
Javascript Solutions
Solution 1 - Javascript
There's no "keycode", it's a separate property on the event object, like this:
if(event.shiftKey && event.keyCode == 9) {
//shift was down when tab was pressed
}
Solution 2 - Javascript
e.keyCode has been deprecated for sometime. Use "e.key" KeyboardEvent.key instead.
Usage:
e.shiftKey && e.key === 'Tab'
Example:
function clicked(e) {
if (e.shiftKey && e.key === 'Tab') {
// Do whatever, like e.target.previousElementSibling.focus();
}
}
Solution 3 - Javascript
you can use the event.shiftKey property for that: <http://www.java2s.com/Code/JavaScript/Event/Shiftkeypressed.htm>
Solution 4 - Javascript
This way it worked for me
By checking first if one of key is pressed(tab/shift ) and then check other inside it:
if (e.code === "Tab") {
if (e.shiftKey) {//shift+tab pressed
//Code
} else {//only tab pressed
//Code
}
}
Solution 5 - Javascript
in my GWT case
if(event.isShiftKeyDown() && event.getNativeKeyCode() == KeyCodes.KEY_TAB){
//Do Something
}
