做一个概述。<code>Form</code> 设计上可以大致分为 3 层：</p>\n<ul>\n<li>数据层：这一层在内部由一个叫 <code>formulr</code> 的内部包构成，它和 UI 无关</li>\n<li>React 绑定层：这一层也在 <code>formulr</code> 内，但只包含最基础的 Hooks（例如 <code>useField</code> 等），依旧和 UI 无关</li>\n<li>UI 层：这一层负责处理数据层和 <code>Zent</code> 组件库的适配，这一层只处理 UI 逻辑，不关心数据的具体处理逻辑</li>\n</ul>\n<h3 class="anchor-heading"><a href="#shu-ju-ceng">¶</a><a href="javascript:void(0)" id="shu-ju-ceng" class="anchor-point"></a>数据层</h3>\n<p>数据层主要由各种类型的 model, validator 以及 builder 构成。model 主要分为以下几种：</p>\n<ul>\n<li><code>IModel</code> 这是最底层 interface，所有 model 都实现它</li>\n<li><code>BasicModel</code> 这是一个 model 的基类，所有 model 都继承自它</li>\n<li><code>FieldModel</code> 单个表单域的 model</li>\n<li><code>FieldArrayModel</code> 一组相同表单域的 model</li>\n<li><code>FieldSetModel</code> 一组有相关性的表单域，通常这些表单域作为一个整体才有意义，比如手机号的国家代码+号码</li>\n<li><code>FormModel</code> 继承自 <code>FieldSetModel</code>，从数据层看就是 <code>FieldSetModel</code>，但是额外添加了一些表单顶层才需要的能力</li>\n<li><code>ModelRef</code> 类似 React 的 ref 概念，它的用处是在不知道具体的 model 类型时用作占位元素。只有 <code>View</code> 模式下才会出现。</li>\n</ul>\n<p>model 是数据和状态的容器，所以 model 上只有操作数据和状态的方法。不管 model 是什么类型，一个 model 上一定维护着值、校验状态、错误信息以及 touched 等一些基础状态，以及读取/操作这些信息的方法。下面是所有 model 上一些常见的方法和属性列表，额外的方法和属性可以通过 <a href="../../apidoc">API 文档</a>中搜索相应的 model 类型查看。</p>\n<ul>\n<li><code>value</code> 获取 model 当前的值</li>\n<li><code>getSubmitValue()</code> 获取用于表单提交的值，可以通过 <code>Field</code> 的 <code>normalize</code> 属性自定义格式化逻辑</li>\n<li><code>initialize(value: Value)</code> 初始化 model 值</li>\n<li><code>patchValue(value: Value)</code> 更新 model 值</li>\n<li><code>reset()</code> 重置 model 为初始值</li>\n<li><code>clear()</code> 重置 model 为默认值</li>\n<li><code>valid()</code> 返回 model 是否通过检验，该函数不会触发校验</li>\n<li><code>validate(options?: ValidateOption)</code> 触发 model 上的校验逻辑</li>\n<li><code>error</code> 获取 model 上的错误信息</li>\n<li><code>clearError()</code> 清楚 model 的错误信息</li>\n<li><code>dirty()</code> model 值是否被修改过</li>\n<li><code>pristine()</code> model 值是否从未被修改过</li>\n<li><code>touched()</code> model 对应的 Field 是否被用户操作过</li>\n</ul>\n<p><code>FieldArrayModel</code> 上还有一批类似数组操作元素的方法，行为和数组上的方法一致，接受值或者 model 对象作为参数。</p>\n<ul>\n<li><code>push</code></li>\n<li><code>pop</code></li>\n<li><code>shift</code></li>\n<li><code>unshift</code></li>\n<li><code>splice</code></li>\n<li><code>filter</code> 该方法直接操作当前的 <code>FieldArrayModel</code> 对象，而不是返回一个新的 <code>FieldArrayModel</code></li>\n<li><code>sort</code></li>\n<li><code>children</code> 获取所有子 model，是个只读数组</li>\n<li><code>get(index: number)</code> 返回指定下标处的子 model 对象</li>\n</ul>\n<p><code>FieldSetModel</code> 上的额外方法：</p>\n<ul>\n<li><code>children</code> 获取所有子 model，是个只读对象</li>\n<li><code>get(name: string)</code> 返回指定名字的子 model 对象</li>\n<li><code>registerChild(name, model): void</code> 注册一个子 model 对象</li>\n<li><code>removeChild(name)</code> 删除一个子 model</li>\n</ul>\n<p>⚠️ 注意：不要直接操作 <code>FieldArrayModel</code> 和 <code>FieldSetModel</code> 的 <code>children</code> 属性（本身就是只读属性），请使用 model 上提供的 mutation API 操作，否则会破坏 model 内部数据一致性，导致不可预期的问题。</p>\n<p>validator 和 builder 下文会详细说明。</p>\n<h3 class="anchor-heading"><a href="#form-de-yun-xing-mo-shi">¶</a><a href="javascript:void(0)" id="form-de-yun-xing-mo-shi" class="anchor-point"></a>Form 的运行模式</h3>\n<p><strong>这是使用 <code>Form</code> 时的一个非常重要的概念，请一定理解清楚。另外，我们推荐使用 <code>Model</code> 模式，而非 <code>View</code> 模式。</strong></p>\n<p>在 <code>ModelRef</code> 里提到了 <code>Form</code> 的 <code>View</code> 模式，这里详细说明以下 <code>Form</code> 的两种运行模式(<code>FormStrategy</code>)，<code>View</code> 模式和 <code>Model</code> 模式。</p>\n<ul>\n<li><code>View</code> 模式是指表单的 model 是通过 UI 的结构，由 <code>Form</code> 自动推导生成的。简单来说，先有 UI，再有 model。上面提到的 <code>ModelRef</code> 即是在一些场景下 model 还未生成时用来做占位的，所以才说 <code>ModelRef</code> 仅出现在 <code>View</code> 模式下。</li>\n<li><code>Model</code> 模式则是由开发者创建好表单的 model 结构，然后作为 <code>Form</code> 的初始化参数传入的，所以是先有 model，再有 UI。</li>\n</ul>\n<p><code>FormStrategy</code> 指明了表单是由视图驱动（View 模式）的还是独立数据驱动（Model 模式），两种模式在使用 API 时也会有差异。</p>\n<ul>\n<li>当使用 <code>View</code> 模式时，表单项组件和 <code>hooks</code> 接受一个 <code>name</code> 参数而不是一个 model。</li>\n<li>当使用 <code>Model</code> 时，由于数据层是在表单外构建的，表单组件必须直接传入该字段对应的 <code>model</code>，而不是 <code>name</code>；但是使用 Form 的 Hooks 时，支持传入字段 <code>name</code> 或者 <code>model</code>，这种场景相当于是一个只读的订阅行为。</li>\n<li>除了上述区别之外，<strong>不同模式下表单组件以及 <code>hooks</code> 会有一些参数不同</strong>，具体请查阅 <a href="../../apidoc">API 文档</a>。</li>\n</ul>\n<h3 class="anchor-heading"><a

用来封装一组相关的表单项处理逻辑。</p>\n</li>\n<li>\n<p>注意并没有所谓的 <code>FieldArray</code> 组件，直接使用 <code>Form.useFieldArray</code> 这个 hooks 即可。该函数有两个重载的实现，分别对应 <code>Form</code>

<code>FieldArrayModel</code>，通过 <code>children</code> 就能访问到所有数据，一般在 <code>render</code> 函数里对 <code>children</code> 做 <code>map</code> 操作即可。</p>\n</li>\n<li>\n<p><code>FieldArrayModel</code> 上还有一些操作方法： <code>push</code>，<code>pop</code>，<code>shift</code>，<code>unshift</code>，<code>splice</code>，类似数组上对应的方法，用于操作子元素。对 <code>FieldArrayModel</code> 内元素做增删应该使用前面说的这些方法，不应该通过 <code>patchValue</code> 来实现增删，因为 <code>patchValue</code> 只更新值，会导致内部 model 状态不一致。</p>\n</li>\n<li>\n<p><code>FieldSet</code> 组件和 <code>Form</code> 一样有两种运行模式，<code>View</code> 模式可以通过 <code>name</code> 参数指定对应的数据来源；<code>Model</code> 模式则通过 <code>model</code> 参数或者 <code>name</code> 参数显式的设置数据来源。</p>\n</li>\n</ul>\n<p><code>FieldSet</code> 两种模式公用的参数可以在<a

模式动态增加/删除表单项</h3>\n<p>有些联动的场景需要在表单项变化的时候动态删除或者增加表单项，我们提供了一组 API 来支持这类使用场景。</p>\n<p>每个 model 上都有一个 <code>builder</code> 的属性，通过这个属性能够获取到这个 model 对应的 builder 对象，通过 <code>builder.build()</code> 方法就可以可以生成一个行为一样的 model 对象。注意，<code>builder</code> 对象仅在通过上述 <code>Builder</code> API 生成的 model，<code>View</code> 模式下的 model 上这个属性永远是空的。</p>\n<p>除此之外，<code>FieldSetModel</code> 以及 <code>FormModel</code> 上提供了两个方法用来完成子 model 的删除和增加：</p>\n<ul>\n<li><code>removeChild<T extends keyof Children>(name: T): Children[T] | null</code></li>\n<li><code>registerChild(name: string, model: BasicModel): void</code></li>\n</ul>\n<p><code>FieldArrayModel</code> 的 <code>push</code>, <code>unshift</code> 以及 <code>splice</code> 方法也支持直接传入 model。</p>\n<p>由于 <code>FieldArrayModel</code>, <code>FieldSetModel</code> 和 <code>FormModel</code> 子 model 的增删需要触发组件重绘，因此提供了额外的 hook 来处理：</p>\n<ul>\n<li><code>Form.useFieldArrayChildModels</code></li>\n<li><code>Form.useNamedChildModel(parent: FieldSetModel, name: string): BasicModel</code>，注意 <code>FormModel</code> 是 <code>FieldSetModel</code> 的子类，所以也适用于这个方法。</li>\n</ul>\n<p>这两个 hook 不监听子 model 内部状态的变化，如有需要，需使用它们返回的 model 对象自行调用 <code>useField</code> 等 hook 来实现。</p>\n<p>通过结合上述这些能力，就可以完成 <code>Model</code> 模式下表单项的动态增删了。</p>'}),o.createElement(zn,{title:"Model 模式动态增删表单项",id:"Demo22",src:'<span class="token keyword

class="anchor-point"></a><code>FieldUtils</code></h3>\n<p><code>FieldUtils</code> 提供了一些有用的工具函数，如果不知道干什么用的或者看不懂，说明你没有需求，不需要用到它们，这些工具本身定位就是高级用法。</p>\n<ul>\n<li>useMulti 用来按顺序调用一批函数，只使用它们的副作用，忽略返回值，<a href="../../apidoc/modules/FieldUtils.html#useMulti">查看函数定义</a></li>\n<li>usePipe 用来从左往右按顺序调用一批函数，上一个函数的返回值作为下一个函数的参数，返回最后一个函数的返回值，<a href="../../apidoc/modules/FieldUtils.html#usePipe">查看函数定义</a></li>\n<li>useCompositionHandler 用来在 <code>model</code> 上维护一个输入法编辑的状态, <code>model.isCompositing</code>，<a href="../../apidoc/modules/FieldUtils.html#useCompositionHandler">查看函数定义</a>。组件内部会根据这个状态在输入法输入阶段跳过校验</li>\n<li>useChangeHandler 生成一个 <code>onChange</code> 回调函数，具体说明请<a href="../../apidoc/modules/FieldUtils.html#useChangeHandler">查看函数定义</a></li>\n<li>compose 与 usePipe 类似，区别是 usePipe 作为 hook 使用，而 compose 可以用在任何地方，例如组合多个校验函数中间件，<a href="../../apidoc/modules/FieldUtils.html#compose">查看函数定义</a></li>\n</ul>'}))}}},82010:(n,a,s)=>{"use strict";s.d(a,{b:()=>m});var
