复制粘贴防止JS代码没有禁用输入（搜索字段）元素？

Question

I used this code to prevent copy/paste function on my site, but in firefox it has disabled the search field too. :(

Is there any way to do this that excludes the input field in this code?

 <script type="text/JavaScript"> function killCopy(e) { return false; } function reEnable(){ return true; } document.onselectstart = new Function("return false"); if (window.sidebar) { document.onmousedown = killCopy; document.onclick = reEnable; } </script>

HTML file

<input id="email" name="email">

jquery code

$('#email').bind('copy paste', function (e) {
        e.preventDefault();
    });

Or

Don't do it. Don't mess with the user's browser. By Copy + Pasting into an E-Mail confirmation field, the user accepts responsibility over what they type. If they are dumb enough to copy + paste a faulty address (it has happened to me) then it's their own damn fault.

If you want to make sure that the E-Mail confirmation works out, have the user check their E-Mail while your site waits ("Please open your webmail program in a new window"). Show the E-Mail address in big fat letters ("The confirmation E-Mail was sent to.... made an error? CLick here to change).

Even better, if you can, let the user have some kind of limited access without confirming. That way, they can log in straight away and you improve your chances to keep in touch with the visitor even if the confirmation mail is blocked due to other reasons (eg spam filters).
