Question

I can’t get this javascript function to work the way I want…

// matches a String that contains kanji and/or kana character(s)

String.prototype.isKanjiKana = function(){
    return !!this.match(/^[\u4E00-\u9FAF|\u3040-\u3096|\u30A1-\u30FA|\uFF66-\uFF9D|\u31F0-\u31FF]+$/);
}

it does return TRUE if the string is made of kanji and/or kana characters, FALSE if alphabet or other chars are present.

I would like it to return if at least 1 kanji and/or kana characters are present instead that if all of them are.

thank you in advance for any help!

Answer 1

String.prototype.isKanjiKana = function(){
    return !!this.match(/[\u4E00-\u9FAF\u3040-\u3096\u30A1-\u30FA\uFF66-\uFF9D\u31F0-\u31FF]/);
}

Don’t anchor it to beginning and end of string with $^ and the + is useless in this case.
