my question is this, I have an array with an object, and I do not know how to overwrite the value of the object I mean,
array = [
usuario: 21312321,
constraseña: "erica"
},...]
What would interest me would be to edit the "erica", thank you very much. PS: I'm using Jquery
I can not understand exactly what you mean (besides, your example lacks the start of the curve key { ).
But let's imagine that this is your array :
array = [
{
usuario: 21312321,
contraseña: "erica",
},
{
usuario: 12154156,
contraseña: "1234",
}
}
To access the password of your first user (both read and write) in the array would be any of these two lines:
array[0].contraseña = "paula"
console.log(array[0].contraseña)
array[0]["contraseña"] = "paula"
console.log(array[0]["contraseña"])
Let me know if this answer is useful or your question was different.
You can do it this way
var data = [{
name: 'Alfredo',
age: 28
}]
console.log(data.name = "Beta")
As you can see inside the console.log() I access the name of the object and later to enter the value I do it as obj.clave and to assign a new value I do it with =nuevovalor
With the destructuring of objects in ES6 you can make it simpler look at this example
var data = {
name: 'Alfredo',
age: 28
}
var {name, age} = data
console.log(name = "jorge")
console.log(age = 89)
I would do it in the following way:
let array = [
{
usuario: 21312321,
constrasena: "erica"
},
{
usuario: 1234,
contrasena: "acire"
}
]
// nuevaContrasena = nueva contraseña
//array = array a iterar
//usuario = usuario para la comparacion
function updateHash(nuevaContrasena, array, usuario) {
array.forEach((elemento) => { // recoremos el elemento
if (elemento.usuario == usuario) { // validamos el usuario al asignarle la contraseña
elemento.contrasena = nuevaContrasena // modificamos la contraseña
}
})
}
console.log(array)
updateHash("nuevapass", array, 1234)
console.log(array)so you know which user you are going to modify the password.
