Tutorial :Javascript multiple keys code



Question:

How to get multiple keys code ?

i.e for Ctrl+g what is the key code ?

The key code for ctrl is 17 and for g is 71. Should i use the key code 88 (17+71) for ctrl+g ?

or for shift+alt+1 etc

Any suggestions, is this possible ? I am using jquery and is there any plugin for this ?

☺☺☺☺


Solution:1

Take a look at the jQuery docs on the subject:

The event object yielded to your handler has a ctrlKey property.

So, e.g.: if( e.keyCode == 71 && e.ctrlKey ) { // ctrl+g }


Solution:2

The KeyboardEvent object will have ctrlKey, shiftKey, altKey, and metaKey properties. Check that evt.ctrlKey is true. There's no need to use jQuery for this. See here for latest (DOM3) documentation: http://www.w3.org/TR/2006/WD-DOM-Level-3-Events-20060413/keyset.html#Modifiers
