General search pipe Angular6

How can I make a general search into a table using pipes in Angular? I have this working snippet, but the value of i is only 0, and I don't know why (and because of that, it will only search for name column only, if I type cc it won't find anything).



How can I modify the code in order to obtain what I want? Thank you for your time!



filter.pipe.ts



transform(value: any, input: string) {
if (!value) {
return ;
}
if (!input) {
return value;
}
var valuesArr =
if (input) {
input = input.toLowerCase();
return value.filter(function (el: any) {
valuesArr = Object.keys(el).map(key => el[key]);
for (var i in valuesArr) {
return valuesArr != null && valuesArr[i] != null && valuesArr[i] != undefined && valuesArr[i].toLowerCase().indexOf(input) > -1;
}
})
}
return value;
}


app.html



<input type="text" [(ngModel)]="toSearch" (click)="onClick(toSearch)">

<table>
<thead>
<tr>
<th>Name</th>
<th>Surname</th>
<th>Group</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let user of users | filter : toSearch">
<td>{{ user.name }}</td>
<td>{{ user.surname }}</td>
<td>{{ user.group }}</td>
<tr>
</tbody>
</table>


app.ts



  toSearch

users = [
{name: "john", surname: "john1", group: null},
{name: "mike", surname: "", group: 'bb'},
{name: "anne", surname: "anne1", group: ''},
{name: "dan", surname: "dan1", group: 'cc'},
{name: "ben", surname: "", group: 'a'},
]

onClick(toSearch) {
this.toSearch = toSearch
}

    While the right answers can be found below. Thought i'd offer a few small changes you could possibly make to clean up the code. First would be to remove if (input) { statement, at this point in the code its guaranteed to be truthy as you just checked !input. Secondly you can change Object.keys(el).map(key => el[key]); to Object.values(el).

Simple just check when your match is true only then send it through



import { Pipe, PipeTransform, Injectable } from '@angular/core';

@Pipe({
name: 'filter',
})
@Injectable()
export class CheckBoxPipe implements PipeTransform {
transform(value: any, input: string) {

if (!value) {
return ;
}
if (!input) {
return value;
}
var values =
if (input) {
input = input.toLowerCase();
return value.filter(function (el: any) {
values = Object.keys(el).map(key => el[key]);
let result = false;
for (var i in values) {
result = values != null && values[i] != null && values[i] != undefined && values[i].toLowerCase().indexOf(input) > -1;
if(result){
return true
}
}
return false;
})
}
return value;
}
}

return valuesArr.some((elm)=> {
