Sorry,there is typing mistake in my question:the returning type of
reEmail() isn't boolean but String,and my code is:
private native String reEmail()/-*{
return
"^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"...@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$";
}-*/;
and it doesn't work.
