Hi.
I have take a look at the code. A lot of the stuff in there seems to be
essential but I did edit the code.
I hope it can be of some help:
interface Dossier {
datas: any[]; // I image this is an Array of a different interface.
name: string;
}
@Pipe({name: 'search2'})
export class TopBarPipe implements PipeTransform {
transform(dossier: Dossier[], searchTerm: string): Dossier[] {
const copy: Dossier[] = [];
if(!dossier) { return copy; };
for (var i = 0, l = dossier.length; i < l; i++) {
if (~dossier[i].name.toLowerCase().indexOf(searchTerm.
toLowerCase())) {
copy.push(dossier[i]);
continue;
}
for (var j = 0, m = dossier[i].datas.length; j < m; j++) {
if (~(dossier[i].datas[j].designationProduit.toLowerCase()).
indexOf(searchTerm.toLowerCase())) {
if (copy.length === 0) {
// New dossier
copy.push({
datas: [dossier[i].datas[j]],
name: dossier[i].name
});
}
else {
for (var k = 0, n = copy.length; k < n; k++) {
if (copy[k].name === dossier[i].datas[j].
idDossier) {
copy[k].datas.push(dossier[i].datas[j]);
}
else {
// New dossier
copy.push({
datas: [dossier[i].datas[j]],
name: dossier[i].name
});
}
}
}
}
}
}
return copy;
}
}
