无法自定义message？ #15
Description
不支持自定义message，请参考https://github.com/jzaefferer/jquery-validation ，很多时候messages节点内提示的文案内容是自定义的
const loginRule = {
rules: {
username: {
type: 'email'
},
password: {
required: true
}
},
messages: {
username: {
required: "请输入用户名.",
email: "请输入正确的邮箱格式"
},
password: {
required: "请输入如密码."
},
}
};
