Use the Chinese characters unicode range to verify whether it is a JavaScript function for Chinese characters.

Function checkchinese (str) {

VAR RE1 = New Regexp ("^ [/ u4e00- / ufa29] * $") // Chinese characters range

Var RE2 = New Regexp ("^ [/ ue7c7- / ue7f3] * $")

Var str = str.replace (/ (^ / s *) | (/ s * $) / g, '');

IF (str == '') {returnaf false;}

IF (! (RE1.TEST (STR) && (! RE2.TEST (STR))))) {

Return False;

}

Return True;
