Diabling Right Click option in a browser using Javascript

By: Guru Singh in Javascript Tutorials on 2008年09月05日 [フレーム]

There are two ways you can disable the 'Right Click' option on a browser's window. These get placed in the <HEAD> of your web page.
First, the easy one:

<SCRIPT>
function click()
{
if (event.button==2)
{ 
alert('Your Warning Message Line 1 here\nYour Warning Message Line 2 here\nYour Warning Message Line 3 here\nYour Warning Message Line 4 here');
}
}document.onmousedown=click
// - ->
</SCRIPT>

Now, the longer one:

This script works in Internet Explorer and Netscape 6:

<SCRIPT LANGUAGE="JavaScript1.1">
<!-- Begin
function right(e) {
var msg = "Right-clicking is not possible in this document.";
if (navigator.appName == 'Netscape' && e.which == 3) {
alert(msg); 
return false;
}
else
if (navigator.appName == 'Microsoft Internet Explorer' &&
event.button==2) {
alert(msg); 
return false;
}
return true;
}
document.onmousedown = right;
// End -->
</SCRIPT>

Users will still be able to view the source from the browser menu (though not many will be persistent enough to figure that out), but you can sort of hide your source code there too. Just start your page with a couple of screens of blank lines and hide the code below the visible window. That will fool most people, especially if you include some bogus code right at the top:

<phtml/unlock code=retrieve:"secure-bin/B23"; print=doc:"B23">

This is total nonsense, but if you tried to view the source code and only saw that, with nothing but white screen beneath it, wouldn't you be fooled?
