if (/^[u4e00-u9fa5]+$/.test(str)) {
alert("The string is all in Chinese");
} else {
alert("This string is not all in Chinese");
}

php

if($en_utf8)
{ $joid = preg_replace("[^0-9a-za-z_-|x4e00-x9fa5|:|/|#|.]","",$joid); > else
{ $joid = preg_replace("[^0-9a-za-z_-|".chr(0xa1)."-".chr(0xff)."|:|/|#|.]","",$ joid); } //Chinese matching of gb2312

} else {
print("This string is not all Chinese");
}
