    Form表单

    具有数据收集、校验和提交功能的表单，包含复选框、单选框、输入框、下拉选择框等元素。

    该组件需要与 Angular表单 结合使用，开发者根据需要可以自由选择 响应式表单 或 模板驱动表单.

    使用该组件前请确保您已经阅读并掌握了 Forms 的使用方式。

    表单

    我们提供了以下三种排列方式：

    • 水平排列：标签和表单控件水平排列；（默认）
    • 垂直排列：标签和表单控件上下垂直排列；
    • 行内排列：表单项水平行内排列。

    表单项 nz-form-item

    表单项用于区分表单中不同的区域，包含表单域和表单标签(可选)。

    表单标签 nz-form-label

    用于标示当前表单项的内容，可选。

    表单域 nz-form-control

    表单一定会包含表单域，表单域可以是输入控件，标准表单域，标签，下拉菜单，文本域等。

    1. <form nz-form>
    2.   <nz-form-item>
    3.     <nz-form-label [nzSpan]="6" nzFor="email">E-mail</nz-form-label>
    4.     <nz-form-control [nzSpan]="14">
    5.       <input nz-input name="email" type="email" id="email">
    6.     </nz-form-control>
    7.   </nz-form-item >
    8. </form>

    响应式表单验证

    我们在 nz-form-control 上 提供了 nzValidateStatusnzHasFeedback 等属性，当使用响应式表单时，可以自己定义校验的时机和内容。

    • nzValidateStatus: 校验状态，默认自动从 nz-form-control 中的 NgControl 获得校验状态，也可以手动指定为特定的 NgControl。
    • nzHasFeedback：用于给输入框添加反馈图标。
    • nzSuccessTipnzWarningTipnzErrorTipnzValidatingTip：设置不同状态校验文案。

    当同一种状态下存在多种提示情况时，nzSuccessTipnzWarningTipnzErrorTipnzValidatingTip 均支持传入 TemplateRef<{ $implicit: FormControl } 类型，可以通过模板变量导出 FormControl 后用于切换不同的提示信息。

    模板驱动表单验证

    当使用模板驱动表单时，模板可以根据模板设定自动进行校验。

    • nzHasFeedback：用于给输入框添加反馈图标。
    • nzSuccessTipnzWarningTipnzErrorTipnzValidatingTip：设置不同状态校验文案。

    当同一种状态下存在多种提示情况时，nzSuccessTipnzWarningTipnzErrorTipnzValidatingTip 均支持传入 TemplateRef<{ $implicit: NgModel } 类型，可以通过模板变量导出 NgModel 后用于切换不同的提示信息。

    动态校验规则
