问题描述
限时送ChatGPT账号..我已经实现了一个 CustomDateAdapter,如下所述:https://medium/@esanjiv/working-with-custom-dateadapter-for-angular-material-2-datepicker-76d4446277dc
I have implemented a CustomDateAdapter as described here: https://medium/@esanjiv/working-with-custom-dateadapter-for-angular-material-2-datepicker-76d4446277dc
现在,我正在执行 Angular Material 6 迁移,但出现以下错误
Now, I am doing the Angular Material 6 migration and I get the following error
core.js:1598 ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'TRIDENT' of undefined
TypeError: Cannot read property 'TRIDENT' of undefined
at CustomDateAdapter.NativeDateAdapter [as constructor] (core.es5.js:792)
at new CustomDateAdapter (custom-date-adapter.ts:21)
at _createClass (core.js:9262)
...
core.es5.js 第 792 行是这样的:
core.es5.js line 792 is this:
_this.useUtcForDisplay = !platform.TRIDENT;
似乎平台未定义.
我注意到在 Material 6 中 NativeDateAdapter 的构造函数发生了变化,它也需要一个平台作为输入.
I noticed that the constructor of the NativeDateAdapter has changed in Material 6, it also requires a platform as input.
constructor(matDateLocale: string, platform: Platform);
我错过了什么?如何在 Angular Material 6 中实现 CustomDateAdapter?
What I am missing? How can I implement a CustomDateAdapter in Angular Material 6?
推荐答案
我遇到了同样的问题.这是我的修复.
I had the same problem. Here is my fix.
// in your shared or main.module.ts
// … other imports
import {Platform, PlatformModule} from '@angular/cdk/platform';
@NgModule({
imports: [
// …
PlatformModule
],
exports: [
// …
PlatformModule
],
providers: [
{provide: DateAdapter, useClass: YourCustomDateAdapter, deps: [MAT_DATE_LOCALE, Platform]},
]
});
export class SharedModule {
}
并且您还没有覆盖 YourCustomDateAdapter
的构造函数.
And you haven't override the YourCustomDateAdapter
's constructor.
