Open sample

fv is the alias of field-validator that you can use it like $ for jquery.

//Define restrictions
var restrictions = {
 name: {
   required: true
 },
 age: {
   required: true,
   type: 'string'
 }
};

//Generate validator by the restrictions
var validator = fv.newInstance(restrictions);
var data = { name:'wangpin'};
//Then perform validation
var result = validator.perform(data);

The result contains standard errors if data is invalid. And if you only need to know if validation is passed or not:

validator.getState();
