Question

I need some help… using Javascript I’m trying to create a parent-child relationship for lists and I’m not sure how to achieve this.

The objective is to have a structure depicted below:

ParentObject 1

1. PO1 List item
2. PO1 List item
3. PO1 List item
4. PO1 List item

ParentObject 2

1. P02 List item
2. P02 List item
3. P02 List item
4. P02 List item

…

I’m not looking for someone to code it out for me, I’m just looking for guidance from the community.

Answer 1

You can create an object with an array as a property.

So

var parent = {
    childlist = [1,2,3,4,5];

}

You can then access the child elements with parent.childlist[index] to get the child at the index position of the list. You can add a new item x to the list with parent.childlist.push(x)

if you want to simplify creating this multiple times you can use a constructor, like this.

var Parent = function(){
    this.childlist = [];
}

var parent1 = new Parent();

var parent2 = new Parent();
