问题
In a HTML page user should not be allowed to copy a text, but at the same time I want to give option for the user to select a particular text (for highlighting purpose). That means CTRL+C should be disabled and CTRL+A should be enabled.
Can anyone tell me how to do this?
回答1:
You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:
<body oncopy="return false" oncut="return false" onpaste="return false">

A more advanced aproach:

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.
回答2:
You can use jquery for this:
$('body').bind('copy paste',function(e) {
e.preventDefault(); return false;
});
Using jQuery bind() and specififying your desired eventTypes .
