Re: How to use javascript's regular expression by jsni?
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.

t...@domain.com)
it will give what I want,but If wrapping it to a JSNI method:

}-*/;
then passing it to the function:
private native boolean validate(String value, String regexp)/-*{
//escape special characters
var re=regexp.replace(/([-()\[\]{}+?*.$\^|,:#!\\])/g,
'\\$1').replace(/\x08/g, '\\x08');

It will give me false.Please tell what mistakes I have made,thanks.

Re: How to use javascript's regular expression by jsni?
\s and \[ (among others) in a JS string are equivalent to s and [,
so you have to escape the backslash.
Also, your escape special characters is messing with your regexp, turning
your [0-9]{1,3} into \[0\-9\]\{1\,3\} (among others) which does not mean
the same thing at all.
Or maybe just use a RegExp literal like you do in Firebug?

Re: How to use javascript's regular expression by jsni?
Hi,
boolean reEmail()
but you are using as a String in validate(t...@domain.com
t...@domain.com,reEmail());
then
regexp in the validate method is 're' when used but 'regexp' as a parameter.
