I am creating a table component in Angular 2, in which I am creating a common table search filter pipe, it is working correctly but not displaying the values in their appropriate columns. When I start typing the search keys in the text box the filtered values are displayed correctly but not under their appropriate columns. Sorry if this question is a duplicated one, I have spent enough time in searching the web but I was unable to get a solution for it.
Below is the code for your reference
component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
public tableData: any = [
{"Name":"Gaurav","Address":"Chennai","Contact":"9632587410"},
{"Name":"Rakesh","Address":"Goa","Contact":"852397410"}
];
}
Pipe.ts
@Pipe({
name: 'searchPipe'
})
export class searchPipe implements PipeTransform {
transform(value: any, args: string[]): any {
let filter = args[0];
if (filter && Array.isArray(value)) {
let filterKeys = Object.keys(filter);
return value.filter(item =>
filterKeys.reduce((key, keyName) =>
key && item[keyName].toUpperCase() === filter[keyName].toUpperCase(), true));
} else {
return value;
}
}
}
component.html
<input type="text" #searchFilter (keyup)="0"/>
<table>
<tr>
<th *ngFor="let colValues of tableData | columnPipe">{{colValues}}</th>
</tr>
<tr *ngFor="let row of tableData">
<td *ngFor="let rowValues of row | rowPipe |searchPipe:searchFilter.value">{{rowValues}}</td>
</tr>
</table>
Full working Plunker, help me in resolving the issues
I guess you want it like this: https://plnkr.co/edit/olkIEiOc67Ld28NuASef?p=preview
You dont want to "hide" the whole td
, instead you just want to "hide" the value..
@Pipe({
name: 'searchPipe'
})
export class searchPipe implements PipeTransform {
transform(value: any, args: string[]): any {
let filter = args[0];
if (filter && Array.isArray(value)) {
let filterKeys = Object.keys(filter);
return value.filter(item => filterKeys.reduce((key, keyName) => key && item[keyName].toUpperCase() === filter[keyName].toUpperCase(), true));
}
// new case !
else if (filter && typeof value === 'string') {
return value.toUpperCase().indexOf(filter.toUpperCase()) >= 0 ? value : '';
}
else {
return value;
}
}
}
<td *ngFor="let rowValues of row | rowPipe">{{ rowValues | searchPipe : searchFilter.value }}</td>
UPDATE
To show the whole row, you have to filter your tableData
.
Change your pipe like this:
@Pipe({
name: 'searchPipe'
})
export class searchPipe implements PipeTransform {
transform(values: any[], filter: string): any {
if (!values || !values.length) return [];
if (!filter) return values;
filter = filter.toUpperCase();
if (filter && Array.isArray(values)) {
const keys = Object.keys(values[0]);
return values.filter(v => v && keys.some(k => v[k] && v[k].toString().toUpperCase().indexOf(filter) >= 0));
}
}
}
<tr *ngFor="let row of tableData | searchPipe : searchFilter.value">
<td *ngFor="let rowValues of row | rowPipe">{{ rowValues }}</td>
</tr>
