I was struggling with Angular search with the use of Custome pipe. So I helped and here below is a code that I have implemented for my friend. Come on follow along with me.
Run below command in terminal
ng g pipe search
app.component.html
<input type="text" class="form-control" placeholder="Search" [(ngModel)]="query" id="listSearch">
<div class="panel panel-default col-xs-12 col-sm-11" *ngFor="let lock of locked | LockFilter: query">
<input type="checkbox" (change)="openModal($event, lock)" class="check" id="{{lock.ID}}">
<label [for]="lock.ID" class="check-label"></label>
<h3 class="card-text name">{{lock.User}}</h3>
<h3 class="card-text auth">{{lock.AuthID}}</h3>
<h3 class="card-text form">{{lock.FormName}}</h3>
<h3 class="card-text win">{{lock.WinHandle}}</h3>
</div>
My app.component file looks like this. Notice our LockedFilter. Which is our search pipe.
app.component.ts
Note: In this file, i have to use dummy records for implementation and testing purpose
import { Component, OnInit } from '@angular/core';
import { FormsModule } from '@angular/forms';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{
public search:any = '';
locked: any[] = [];
constructor(){}
ngOnInit(){
this.locked = [
{ID: 1, User: 'Agustin', AuthID: '68114', FormName: 'Fellman', WinHandle: 'Oak Way'},
{ID: 2, User: 'Alden', AuthID: '98101', FormName: 'Raccoon Run', WinHandle: 'Newsome'},
{ID: 3, User: 'Ramon', AuthID: '28586', FormName: 'Yorkshire Circle', WinHandle: 'Dennis'},
{ID: 4, User: 'Elbert', AuthID: '91775', FormName: 'Lee', WinHandle: 'Middleville Road'},
]
}
}
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { SearchPipe } from './_pipe/search/search.pipe';
@NgModule({
declarations: [
AppComponent,
SearchPipe
],
imports: [
BrowserModule,
FormsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
search.pipe.ts
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'LockFilter'
})
export class SearchPipe implements PipeTransform {
transform(value: any, args?: any): any {
if(!value)return null;
if(!args)return value;
args = args.toLowerCase();
return value.filter(function(item){
return JSON.stringify(item).toLowerCase().includes(args);
});
}
}
Hope this helps!
