Use JS to set shortcut keys for combination

The essence of using JS to set shortcut keys is to get the keycode value of the key you want to set, if you want to add ctrl,alt,shift, then added a ctrlkey,altkey,shiftkey to judge, so the key is to get the value of KeyCode.

(1) Set CTRL +enter Commit

if (e.ctrlkey && e.keycode = =) { 2 return submit (); 3}    

(2) Set ALT + arrow key ← Submit

if (e.altkey&& E.keycode = = PNs) {  2 return3}   

(3) Setting SHIFT+F10 submission

if (e.shiftkey&& E.keycode = = PNs) {  2 return submit ();  4}    　

(4) Set Enter submit

if (E.keycode = =) {2 return submit (); 3}    

Some common shortcut keys for keycode:

<script type= "Text/javascript" >

Call the Hotkey function when the onkeydown event occurs
$ ("#CarNo"). KeyDown (function (e) {
if (E.keycode = = 13)
{
Alert ("You press keyboard enter.");
}
});

</script>
