访问另一个对象内的对象属性

Question

I´m new to Firebase and I want to access the 'name' and 'score' properties. How could I do this?

Here is the db-structure:

I get the whole database like this(following this tutorial ), but I dont knwo how I could access the properties of the objects(for example the name of '-Kk50CJUCI...') inside.

scores.on('value', getData, errData)

function getData(data) {
    console.log(data.val())
}

function errData (err) {
    console.log(err)
}

Thanks! :)

Answer 1

By adding a child_added event listener, you will get each child node (-Kk50CJUCI.. etc.) individually. You can then directly access the child properties of the data.val() as below:

scores.on('child_added', getData, errData)

function getData(data) {
    console.log(data.val().name)
    console.log(data.val().score)
}

function errData (err) {
    console.log(err)
}
