'Properly filter names on an array in java
so I have this data on an array and I need to only appear [ {apellido_paterno:"algo",nombre: "jose"} ] in the output but its showing all 3 of the objects
let data = [{nombre: 'joselyn',apellido_paterno:'poblete'},
{nombre:'jose',apellido_paterno:'algo'},
{nombre:'ernesto',apellido_paterno:'joseludo'}]
const filtro = 'jose'
data = data.filter((row) =>{
const nombreCompleto = `${row.nombre}${row.apellido_paterno}`.toLowerCase()
const nombreCompletoReves = `${row.apellido_paterno}${row.nombre}`.toLowerCase()
const nombreTrimmed = filtro.replace(/\s+/g, '').toLowerCase()
return nombreCompleto.includes(nombreTrimmed) || nombreCompletoReves.includes(nombreTrimmed);
})
console.log(data)
// expected output [{apellido_paterno:"algo",nombre: "jose"}]
// output [{apellido_paterno: "poblete",nombre: "joselyn"},{apellido_paterno:"algo",nombre: "jose"},
// {apellido_paterno: "joseludo",nombre: "ernesto"}]

If I understand correctly, you want to filter the object where nombre
is jose
. You can just .filter()
on data. Like this
let data = [{
nombre: 'joselyn',
apellido_paterno: 'poblete'
},
{
nombre: 'jose',
apellido_paterno: 'algo'
},
{
nombre: 'ernesto',
apellido_paterno: 'joseludo'
}
]
const filtro = 'jose'
data = data.filter(x => x.nombre == filtro);
console.log(data)

Here is the working code
let data = [
{ nombre: "joselyn", apellido_paterno: "poblete" },
{ nombre: "jose", apellido_paterno: "algo" },
{ nombre: "ernesto", apellido_paterno: "joseludo" },
// line added by me to demonstrate the first example
{ nombre: "javier", apellido_paterno: "jose rodrigo" }
];
const filtro = "jose";
console.log("filtro wrapped by spaces in any part of row.nombre or row.apellido_paterno",
data.filter(row =>
(row.nombre + " " + row.apellido_paterno)
.toLowerCase()
.split(" ")
.includes(filtro)
)
);
console.log("filtro strictly matches row.nombre or row.apellido_paterno",
data.filter(row =>
row.nombre == filtro ||
row.apellido_paterno == filtro
)
);
