var IGNORED_TYPES = [
    'file',
    'reset',
    'submit',
    'button'
].reduce(function(acc, type) {
    acc[type] = 1;
    return acc;
}, {});
var VALUE_MISSING_MESSAGES = {
    checkbox: msg.valueMissingCheckbox,
    radio: msg.valueMissingRadio,
    'select-one': msg.valueMissingSelect,
    'select-multiple': msg.valueMissingSelectMulti
};
var TYPE_MISMATCH_MESSAGES = {
    email: msg.typeMismatchEmail,
    url: msg.typeMismatchURL
};

function getError(field) {
    var validity = field.validity;
    var type = field.type;
    switch (true) {
    case (validity.valid || field.disabled || type in IGNORED_TYPES):
        return;
    case validity.valueMissing:
        return VALUE_MISSING_MESSAGES[type] || msg.valueMissing;
    case (validity.typeMismatch && type in TYPE_MISMATCH_MESSAGES):
        return TYPE_MISMATCH_MESSAGES[type];
    case validity.tooShort:
        return msg.tooShort(field);
    case validity.tooLong:
        return msg.tooLong(field);
    case validity.badInput:
        return msg.badInput;
    case validity.stepMismatch:
        return msg.stepMismatch;
    case validity.rangeOverflow:
        return msg.rangeOverflow;
    case validity.rangeUnderflow:
        return msg.rangeUnderflow;
    case validity.patternMismatch:
        if (field.hasAttribute('title'))
            return field.getAttribute('title');
        return msg.patternMismatch;
    }
    return msg.generic;
}
