错误:模板解析错误:在角度中找不到管道“过滤器" [英] Error: Template parse errors: The pipe 'filter' could not be found in angular

问题描述

导入此过滤器

// search module
import { Ng2SearchPipeModule } from 'ng2-search-filter';

它的 HTML 代码

//search

<input class="form-control" type="text" name="search" [(ngModel)]="searchText" autocomplete="off" placeholder="search">

//Assigned filter to table

 <tr *ngFor="let bookName of NameOfBookList | filter:searchText">

任何帮助将不胜感激.

推荐答案

仅将 Ng2SearchPipeModule 添加到对我有用的导入中.添加到声明时，我的浏览器工具中出现错误，指出 Ng2SearchPipeModule 有意外声明.

Adding Ng2SearchPipeModule ONLY to the imports worked for me. When adding to the declarations I got an error in my browser tools stating that there was an unexpected delcaration for Ng2SearchPipeModule.

@NgModule({
declarations: [
    AppComponent,
    ListComponent
],
imports: [
    BrowserModule,
    FormsModule,
    Ng2SearchPipeModule
],
providers: [],
bootstrap: [AppComponent]
})

然后在我的标记中:

<input [(ngModel)]="term">
...
<tbody *ngFor="let d of myList |filter:term">
