2, <script>function Document.oncontextmenu () {event.returnvalue=false;} Block right mouse button </script>
3. In the body attribute, add
<body onbeforecopy= "return false" oncontextmenu= "return False"
Oncopy=document.selection.empty (2) ondragstart= "return false"
Onmouseup=document.selection.empty (2) onselect=document.selection.empty (2)
Onselectstart= "return False" >
4, in fact, as long as you put the site source code to encrypt it can
Add the following code to the Web page <body oncontextmenu= "return false" onselectstart= "return False"
Ondragstart= "return false" onbeforecopy= "return False" Oncopy=document.selection.empty () onselect= Document.selection.empty () >
This can also be <script language= "JavaScript" >
function Helpor_net ()
{
if (event.button==2) alert (' for browsing only! Thank you!\n\n if you have any questions please contact me! ‘)
}
</script>
Then change <body> to <body onmousedown= "helpor_net ()" >
If you have the energy to look at the following code:
Prohibit save page
1. Prohibit Save As
<nos cript><iframe Src=-.html></iframe></nos cript>
Join the head.
2. Prohibit right-click
<body oncontextmenu= "return false" >
Or
<s cript language= "Javas cript" >
<!--
if (window. Event)
Document.captureevents (Event.mouseup);
function Nocontextmenu ()
{
Event.cancelbubble = True
Event.returnvalue = false;
return false;
}
function Norightclick (e)
{
if (window. Event)
{
if (E.which = = 2 | | e.which = = 3)
return false;
}
Else
if (Event.button = = 2 | | event.button = = 3)
{
Event.cancelbubble = True
Event.returnvalue = false;
return false;
}
}
Document.oncontextmenu = Nocontextmenu; For ie5+
Document.onmousedown = Norightclick; For all others
-
</S cript>
3. Let the page text not be selected and copied
<body onselectstart= "return false" >
Or
<body Oncopy=alert (' Sorry, no copying! ');event.returnvalue=false;>
4. Lock status bar text to prevent the address from appearing
<body onmouseover= "self.status= ' text '; return true" >
7. Prohibit image download
At the end of <body......> here add:
Oncontextmenu= "return false" ondragstart= "return false" onselectstart= "return false" scroll= "Auto"
5. Disable caching
<meta http-equiv= "Expires" content= "0" >
<meta http-equiv= "Cache-control" content= "No-cache" >
<meta http-equiv= "Pragma" content= "No-cache" >
Put it in the head.
