I want to loop through a JSON like this using javascript.
{
persons: [
Person {
name: 'Herbert',
age: 70
},
Person {
name: 'Peter',
age: 67
}
]
}
My first approach was something like this, but this is not working somehow :(
personArray.forEach((person) => {
console.log(person.name);
});
You may use this to get name:
let personArray = {
persons: [
{
name: 'Herbert',
age: 70
},
{
name: 'Peter',
age: 67
}
]
}
personArray.persons.map(ele => ele.name) // ['Herbert', 'Peter']
JSON does not have forEach, you need to do like this:
let personArray = {
persons: [
{
name: 'Herbert',
age: 70
},
{
name: 'Peter',
age: 67
}
]
}
Object.keys(personArray.persons).forEach((key) => {
console.log(personArray.persons[key].name);
});Your json looks invalid. If I understood you correctly, you can do the following:
let json = '{"persons":[{"name":"Herbert","age":70},{"name":"Peter","age":67}]}'
let personArray = JSON.parse(json)
personArray.persons.forEach((person) => {
console.log(person.name);
});
or, if it is a real javascript object, do the following:
let personArray = {
persons: [
{
name: 'Herbert',
age: 70
},
{
name: 'Peter',
age: 67
}
]
}
personArray.persons.forEach((person) => {
console.log(person.name);
});
