<a href= "Web effects:
Location.replace (URL) ">
JavaScript Mask main Window scroll bar

Add it to the body tag.
Style= "Overflow-y:hidden"
JavaScript screen screen, constantly emptying clipboard
Add it to the body tag.
Onload= "SetInterval (' Clipboarddata.setdata (' Text ', ') ', 100)"
The printing function of JavaScript masking website
<style>
@media Print {
* {Display:none}
}
</style>

JavaScript mask IE6.0 Save icon automatically appears on a picture
Method One:

<meta http-equiv= "Imagetoolbar" content= "no" >

Method Two:


All script in the JavaScript mask page
<noscrript></noscript>


JavaScript Mask F5 Key
The code is as follows

<script language= "JavaScript" >
<!--
function Document.onkeydown ()
{
if (event.keycode==116)
{
Event.keycode = 0;
Event.cancelbubble = true;
return false;
}
}
-->
</script>

Screen browser in the upper right corner, minimize, maximize, close key

<script language=javascript>
function Window.onbeforeunload ()
{
if (event.clientx>document.body.
clientwidth&&event.clienty<0| | Event.altkey)
{
Window.event.returnvalue = "";
}
}
</script>

or open the page with full screen

<script language= "JavaScript" >
<!--
window.open (www.zutiai.com, "32pic", "fullscreen=3,height=100,
width=400, Top=0, left=0, Toolbar=no, Menubar=no,
Scrollbars=no, Resizable=no,location=no, Status=no ");
-->
</script>

Note: Add onbeforeunload= "Javascript:return false" to the body tag (so that the window cannot be closed)


The JavaScript code that implements all keys for the screen keyboard is as follows:

<script language= "JavaScript" >
<!--
function Document.onkeydown () {
Event.keycode = 0;
Event.returnvalue = false;
}
-->
</script>


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 shielding method is ineffective.

if ((Event.keycode = 8) &&
(event.srcElement.type!= "text" &&
Event.srceleme Nt.type!= "textarea" &&
Event.srcElement.type!= "password") | | Mask backspace Delete key
(event.keycode==116) | |//Shielding F5 Refresh key
(Event.ctrlkey && event.keycode==82)) {//ctrl + R
event. keycode=0;
Event.returnvalue=false;
}
if ((Event.ctrlkey) && (event.keycode==78))//Mask 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;//Mask Shift Plus left mouse button new page
if ((Window.event.altKey) && (window.event.keycode==115)) {//Mask 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
The first method:

window.open ("your. htm", "", "Toolbar=no,location=no,directories=no,menubar=no,
Scrollbars=no,resizable=yes,status=no,top=0,left=0 ")

The second way is to open a Full-screen page:


window.open ("Your. asp tutorial", "", "Fullscreen=yes")

JavaScript Mask right mouse button can also be added to the body tag oncontextmenu=

Self.event.returnvalue=false

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>
In addition


Oncontextmenu= "Window.event.returnvalue=false" will completely mask the right mouse button
<table border Oncontextmenu=return (false) ><td>no</table>
Available for table

<body onselectstart= "return false" > deselect, Prevent replication

Oncopy= ' return false; ' oncut= ' return false; ' Prevent replication


JavaScript block keyword, presumably the idea is to use JavaScript to replace the existing text, to achieve the purpose of replacement <script

language= "javascript1.2" >
function Test () {
if ((A.b.value.indexof ("* *") = = 0) | | (A.b.value.indexof ("* * *") = = 0)) {
Alert (":)");
A.b.focus ();
return false;}
}
</script>
<form name=a onsubmit= "return Test ()" >
<input Type=text name=b>
<input type= "Submit" name= "Submit" value= "Check" >
</form>
