mobx-form-model v0.10.9

Document is Working in progress. Welcome to fork :)

Minimal form model that supports to validating and dirty-checking based on Mobx.

Most features are copied from Angular forms

npm install -S mobx-form-model

Examples

// Simple Controller
import FormController from 'mobx-form-model';

const ctrl = new FormController('', [
  ({ value }) =>
    value == null || !value.length ? { required: 'value required' } : undefined
]);

ctrl.valid; // false
ctrl.errors.required; // value required

ctrl.update('hello');
ctrl.valid; // true
ctrl.errors; // undefined
ctrl.dirty; // true

// nested controllers
import FormController, {
  FormControllerGroup,
  FormControllerArray
} from 'mobx-form-model';

const form = new FormControllerGroup({
  name: new FormController('Tom'),
  firstStep: new FormControllerGroup({
    gender: new FormController(1),
    birthday: new FormController('1990-01-01')
  }),
  questioins: new FormControllerArray([
    new FormController(),
    new FormController()
  ])
});

Controller vs Group vs Array

Shared

Properties

• value，当前的值
• valid, true 表示当前没有错误
• dirty, 表示值是否变更过。
• errors, 所有validator执行玩合并后的结果

• enabled, 表示当前controller是否有效。false表示当前controller不会影响parent controller的valid、dirty值。

以上这些属性都是 observable

Methods

• disable()
• enable()
• markAsPristine() 将dirty设置为false，比如表单提交之前先检查dirty，用户没修改表单就无需重复提交，那在表单提交后调用 markAsPristine() 就可以避免重复提交已经提交的表单。
