How can you create a multidimensional array that contains keys and then traverse it with foreach.
It's because I have an array with data in php and I want to return it with ajax to jquery.
I have this and it does not work. And I want to do it with foreach ();
var persona = [
var persona1 = ["nombre"=>"Luis","Edad"=>"32"],
var persona2 = ["nombre"=>"Alex","Edad"=>"27"]
]
for(var i=0;i<persona.length;i++){
alert(persona[i]["nombre"]);
} Your syntax is wrong, to declare the fix personas you should do so
var persona = [
persona1 = {"nombre": "Luis","Edad": "32"},
persona2 = {"nombre": "Marcos","Edad": "15"},
]
And there your for would work perfect, but if you still want to do it with a foreach I leave you a working Snippet:
var personas = [
persona1 = {"nombre": "Luis","Edad": "32"},
persona2 = {"nombre": "Marcos","Edad": "15"},
]
personas.forEach(function(persona, index) {
console.log("Persona " + index + " | Nombre: " + persona.nombre + " Edad: " + persona.Edad)
});I hope I have been helpful. Greetings!
The simplest foreach statement in JS is:
for(var i in personas){
console.log(personas[i].nombre);
}
However, the correct way to build objects is with the {} keys, since with [] you indicate an array . To build your objects there are two ways:
Direct assignment:
var personas = [
persona1 = {"nombre":"Luis","Edad":"32"},
persona2 = {"nombre":"Alex","Edad":"27"}
]
or just
var personas = [
{"nombre":"Luis", "Edad":"23"},
{"nombre":"Alex", "Edad":"27"}
]
Definition (of object):
function Persona(nombre, edad){
this.nombre = nombre;
this.edad = edad;
}
var personas = [new persona("Luis", 32), new persona("Alex", 27)];
for(pers in personas){
console.log(pers.nombre);
}
I leave you a small POO tutorial in JavaScript so that you clarify your doubts.
