为应用程序中的所有输入设置默认指令

问题描述

我使用带有自定义 css 的 mat-form-field 来改变看起来像 appearance="outline" 指令.

I use mat-form-field with custom css in order to change the be look like appearance="outline" directive.

在 Angular Material v 7.2.1 中 appearance="outline" 被添加到 mat-form-field 选项中.

In Angular Material v 7.2.1 appearance="outline" was added to the mat-form-field options.

如何将 appearance="outline" 声明为应用中每个输入字段的默认值?

How can I declare appearance="outline" as a default for each input fields in my app?

推荐答案

你可以尝试在你的 @NgModule 中注入 mat-form-field 默认选项:

you can try to inject mat-form-field default options in your @NgModule:

...
providers: [
   { provide: MAT_FORM_FIELD_DEFAULT_OPTIONS, useValue: { appearance: 'outline' } }
],
...

此https://github.com/angular/material2/issues/存在问题12765，但我相信已经解决了.
