JS method to shield the keyboard from being unavailable and the right mouse button from being unavailable_javascript skills

I did two small experiments today, blocking the keyboard from working and blocking the right mouse button from working

Experiment 1, shielded keyboard is not available

There are 3 keyboard events

a. keydown: Triggered when a key on the keyboard is pressed. If a key is held down, it will continue to trigger

b. keypress: Triggered when a key is pressed and a character is generated, that is, function keys such as Shift, Alt, Ctrl, etc. are ignored

c, keyup: triggered when a key is released

Copy code The code is as follows:

< ;script language="javascript">

function block(oEvent) {
if (window.event) {

oEvent = window.event; }                                                                                                                                                                                                                             block; < ;/script>

Haha~ The blocking function is implemented as above
