Async Validator 异步验证使用说明

{
 a:xxx,
 b:xxx
}

{
 a:[
  {验证规则, message: 'xxx'},
  {验证规则, message: 'xxx'}
 ],
 b:[
  {验证规则, message: 'xxx'}
 ]
}

var inputData = {'item':'12345'}
var rules = [
 {required: true, message: '年龄不能为空'},
 {type: 'number', message: '年龄必须为数字值'}
]
function validateData() {
 var validateRuler = new Promise(function (resolve, reject) {
 var validator = new AsyncValidator(rules)
 validator.validate(inputData, { firstFields: true }, (errors, fields) => {
  resolve(errors)
 })
 return validateRuler
}
function validate() {
 validateData().then(function (errors) {
  console.log(errors)
  if (errors === null) {
    // 通过验证，该干嘛干嘛
  } else {
    // 把验证结果展示在页面上
  }
 })
}
validate()
