簡単なCRUDアプリケーションを実行しました。次に、テーブルをフィルタリングする検索バーを追加して、数字と同じ文字で行を表示する必要があります。
コンポーネントで何をすべきかわかりません。パイプとフィルターでさまざまなものを見ましたが、プロジェクトに適応させることができませんでした。
新しいメソッドを作成せずにcomponent.tsに実装できるメソッドがあるかどうか知りたいのですが。
COMPONENT.HTML
<div class="container">
<ul class="table-wrapper">
<div class="table-title">
<div class="row">
<div class="col-sm-4">

<div class="show-entries">

</div>
<div class="col-sm-4">

<div class="col-sm-4">

(click)="actionFunc(act, user)">{{act.label}}</button>
</td>
</tr>
</tbody>
</table>
<div align="center">
<!--<div class="hint-text">Showing <b>{{totUsersPerPage}}</b> out of <b>{{users.length}}</b> entries</div>-->
<ul align="center">

COMPONENT.TS、ここでは、アプリで機能する適切なメソッドを作成する必要があります。
export class DynamicTableComponent implements OnInit {
constructor(private userService: UserService,
private resourcesService: ResourcesService,
private router: Router) {
}
@Input()
users = [];
@Input()
columns: string[];
@Input()
actions = [];
@Input()
metadata: any;
@Input()
class;
direction = false;
columnSorted = '';
public rowsOnPageSet = ['5', '10', '15', '20', '25'];
page = 1;
private pageSize = 5;
searchVal = '';
/*totalPages = Math.trunc(this.users.length / this.pageSize);
totUsersPerPage = this.pageSize;*/
ngOnInit() {
}
actionFunc(action, element: any) {
if (action.actionType === 'DELETE') {
/*...*/
}
}
if (action.actionType === 'GO_TO') {
/*...*/
}
}
addFunc(metadata) {
if (metadata.addMD.actionType === 'ADD_TO') {
/*...*/
}
}
maxElements(maxPerPage) {
this.rowsOnPageSet = maxPerPage;
}
sortTable(param) {
/*...*/
}
getClassCondition(act) {
return act === 'DELETE' ? this.class = 'btn btn-danger' : 'btn btn-primary';
}
pageChanged($event: number) {
/*...*/
}
checkSearchVal() {
this.users.slice();
const filteredUsers: User[] = [];
if (this.searchVal && this.searchVal !== '') {
for (const selectedUser of this.users) {
if (selectedUser.firstName.toLowerCase().search(this.searchVal.toLowerCase()) !== -1 ||
selectedUser.lastName.toLowerCase().search(this.searchVal.toLowerCase()) !== -1) {
filteredUsers.Push(selectedUser);
}
}
this.users = filteredUsers.slice();
}
}
}
データ構造:in.memory-data.service.ts
import { InMemoryDbService } from 'angular-in-memory-web-api';
import { User } from './user';
import { Injectable } from '@angular/core';
export const COLUMNS = ['id', 'firstName', 'lastName', 'age'];
@Injectable({
providedIn: 'root',
})
export class InMemoryDataService implements InMemoryDbService {
createDb() {
const USERS = [
{id: 1, firstName: 'NAME_1', lastName: 'SURNAME_1', age: 23},
{id: 2, firstName: 'NAME_2', lastName: 'SURNAME_2', age: 23},
{id: 3, firstName: 'NAME_3', lastName: 'SURNAME_3', age: 23},
{id: 4, firstName: 'NAME_4', lastName: 'SURNAME_4', age: 24},
{id: 5, firstName: 'NAME_5', lastName: 'SURNAME_5', age: 42},
{id: 6, firstName: 'NAME_6', lastName: 'SURNAME_6', age: 41},
{id: 7, firstName: 'NAME_7', lastName: 'SURNAME_7', age: 24},
{id: 8, firstName: 'NAME_8', lastName: 'SURNAME_8', age: 25},
{id: 9, firstName: 'NAME_9', lastName: 'SURNAME_9', age: 25},
{id: 10, firstName: 'NAME_10', lastName: 'SURNAME_10', age: 25},
{id: 11, firstName: 'NAME_11', lastName: 'SURNAME_11', age: 22},
{id: 12, firstName: 'NAME_12', lastName: 'SURNAME_12', age: 22},
{id: 13, firstName: 'NAME_13', lastName: 'SURNAME_13', age: 24},
];
return {USERS};
}
}
user.ts
export class User {
id: number;
firstName: string;
lastName: string;
age: number;
}
私はあなたがあなたの答えを得たのを見ました... ここ はそれが価値があるもののための別のアプローチです...コメントで議論されているように...
checkSearchVal() {
this.USERS = masterUSERS.slice();
let filteredUsers: User[] = [];
if (this.searchVal && this.searchVal != '') {
/* NORMAL FOR
for(var i=0; i<this.USERS.length; i++ ){
if(this.USERS[i].firstName.toLowerCase().search(this.searchVal.toLowerCase()) != -1 || this.USERS[i].lastName.toLowerCase().search(this.searchVal.toLowerCase()) != -1 ){
filteredUsers.Push(this.USERS[i])
}
}
*/
/* FOR EACH
this.USERS.forEach((selectedUser) => {
if (selectedUser.firstName.toLowerCase().search(this.searchVal.toLowerCase()) != -1 ||
selectedUser.lastName.toLowerCase().search(this.searchVal.toLowerCase()) != -1) {
filteredUsers.Push(selectedUser);
}
})
*/
/* FOR OF */
for (let selectedUser of this.USERS) {
if (selectedUser.firstName.toLowerCase().search(this.searchVal.toLowerCase()) != -1 ||
selectedUser.lastName.toLowerCase().search(this.searchVal.toLowerCase()) != -1) {
filteredUsers.Push(selectedUser);
}
}
this.USERS = filteredUsers.slice();
}
}
update:this.USERS = FilteredUsers.slice();を移動しました。 IF内
update:2:forEachおよびFor-Ofと同じコード(TSLintエラーを取り除くため)
テーブルをフィルタリングするには、PIPE.tsファイルを作成するだけです。
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'filterAll'
})
export class FilterPipe implements PipeTransform {
transform(value: any, searchText: any): any {
if(!searchText) {
return value;
}
return value.filter((data) => this.matchValue(data,searchText));
}
matchValue(data, value) {
return Object.keys(data).map((key) => {
return new RegExp(value, 'gi').test(data[key]);
}).some(result => result);
}
}
FilterPipeをapp.module.ts in declarationsに追加し、これをcomponent.htmlに追加します。
<form id="searchForm">
<div class="form-group">
<div class="input-group" id="filterAll">
<div class="input-group-addon"><i class="glyphicon glyphicon-search"></i></div>
<input type="text" class="form-control" name="searchString" placeholder="Search..." [(ngModel)]="searchString">
</div>
</div>
</form>
次に、次のようにテーブルのTRにパイプを追加します。
<tr *ngFor="let user of users | paginate: {itemsPerPage: pageSize,
currentPage: page,
totalItems: users.length} | filterAll: searchString">
Component.tsファイルを忘れてしまいました。申し訳ありません。searchString変数を次のように配置する必要があります。
public searchString: string;
