One, screen Keyboard all keys
<script language= "JavaScript" >
<!--
function Document.onkeydown () {
Event.keycode = 0;
Event.returnvalue = false;
}
-->
</script>
Second, shielding the right mouse button
Add Oncontextmenu=self.event.returnvalue=false to the body tag or:
<script language= "JavaScript" >
<!--
function Document.oncontextmenu ()
{
return false;
}
-->
</script>
function Nocontextmenu ()
{
if (document.all) {
Event.cancelbubble=true;
Event.returnvalue=false;
return false;
}
}
Or:
<body onmousedown= "Rclick ()" oncontextmenu= "Nocontextmenu ()" >
<script language= "JavaScript" >
<!--
function Rclick ()
{
if (document.all) {
if (Event.button = = 2) {
Event.returnvalue=false;
}
}
}
-->
</script>
Third, shielding CTRL + N, SHIFT+F10, F5 refresh, backspace key
<script language= "JavaScript" >
<!--
Screen the right mouse button, CTRL + N, SHIFT+F10, F5 refresh, backspace key
function Window.onhelp () {return false}//Shield F1 Help
function KeyDown () {
if ((Window.event.altKey) &&
((window.event.keycode==37) | |//Shielding ALT + Direction key ←
(window.event.keycode==39))) {//Shielding ALT + Direction key →
Alert ("You are not allowed to use ALT + arrow keys forward or back page!") ");
Event.returnvalue=false;
}
Note: This is not really shielding ALT + direction key, because ALT + arrow pop-up warning box, hold down the ALT key, with the mouse point off the warning box, this
The shielding method is ineffective.
if ((Event.keycode = 8) &&
(Event.srcElement.type!= "text" &&
Event.srcElement.type!= "textarea" &&
Event.srcElement.type!= "password") | | Mask BACKSPACE Delete key
(event.keycode==116) | | Mask F5 Refresh Key
(Event.ctrlkey && event.keycode==82)) {//ctrl + R
event.keycode=0;
Event.returnvalue=false;
}
if ((Event.ctrlkey) && (event.keycode==78))//Shield CTRL + N
Event.returnvalue=false;
if ((Event.shiftkey) && (event.keycode==121))//Shielding SHIFT+F10
Event.returnvalue=false;
if (Window.event.srcElement.tagName = "A" && Window.event.shiftKey)
Window.event.returnvalue = false; Screen shift plus left mouse button new page open
if ((Window.event.altKey) && (window.event.keycode==115)) {//Shield ALT+F4
Window.showmodelessdialog ("About:blank", "" "," dialogwidth:1px;dialogheight:1px ");
return false;}
}
In addition, you can use the Window.Open method to screen IE's all menus
