JavaScript TV4对象评估，NodeJS

Question

Folks, I am trying to add a tv4 format, however, the following is not matching regex for whatever reason.

tv4.addFormat({
    'year': function (data, schema) {
        if (typeof data === 'string' && !/^(19|20)\d{2}$/.test(data)) {
            return null;
        }
        return 'Year must be between 1900 - 2099';
    }
});

Regex is supposed to match 1900-2099 for year validation. As per : https://github.com/geraintluff/tv4

Thoughts? :)

Answer 1

This might work better

tv4.addFormat({
    'year': function (data, schema) {
        var i = parseInt(data);
        if (i.toString() === data && i >= 1900 && i <= 2099) {
            return null;
        }
        return 'Year must be between 1900 - 2099';
    }
});
