为应用程序中的所有输入设置默认指令 [英] Set default directive for all input in app

问题描述

我将mat-form-field与自定义css一起使用，以更改外观像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中将appearance="outline"添加到了mat-form-field选项中.

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

如何为应用程序中的每个输入字段声明appearance="outline"作为默认值?

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

推荐答案

您可以尝试在@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' } } 
],
...
