Answer 1

1. 仅限英语

var only_english = 'abcdAbDKDk',
    mixed = '????aaSDSD';

if (/[^A-Za-z]/g.test(only_english)) {
    alert('"only_english" contains characters other than English');
} else {
    alert('"only_english" contains only English characters');
}

if (/[^A-Za-z]/g.test(mixed)) {
    alert('"mixed" contains characters other than English');
} else {
    alert('"mixed" contains only English characters');
}

2. 仅限波斯语

var only_persian = '????',
    mixed = '????aaSDSD';

if (/[^\u0600-\u06FF]/g.test(only_persian)) {
    alert('"only_persian" ontains characters other than Persian');
} else {
    alert('"only_persian" ontains only Persian characters');
}

if (/[^\u0600-\u06FF]/g.test(mixed)) {
    alert('"mixed" contains characters other than Persian');
} else {
    alert('"mixed" contains only Persian characters');
}

3. 只有数字

var only_numbers = '12334',
    mixed = '3124adqad';

if (/[^0-9]/g.test(only_numbers)) {
    alert('"only_numbers" does not contain only numbers');
} else {
    alert('"only_numbers" contains only numbers');
}

if (/[^0-9]/g.test(mixed)) {
    alert('"mixed" does not contain only numbers');
} else {
    alert('"mixed" contains only numbers');
}
