filter for ngfor angular code example
Example: angular filter ngfor
filterargs = {title: 'hello'};
items = [{title: 'hello world'}, {title: 'hello kitty'}, {title: 'foo bar'}];
In your template, you can pass string, number or object to your pipe to use to filter on:
<li *ngFor="let item of items | myfilter:filterargs">
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'myfilter',
pure: false
})
export class MyFilterPipe implements PipeTransform {
transform(items: any[], filter: Object): any {
if (!items || !filter) {
return items;
}
return items.filter(item => item.title.indexOf(filter.title) !== -1);
}
}
import { MyFilterPipe } from './shared/pipes/my-filter.pipe';
@NgModule({
imports: [
..
],
declarations: [
MyFilterPipe,

providers: [

bootstrap: [AppComponent]

export class AppModule { }
