    Looping through an objects children

    ljonny18 Level 1
      This post is related to another post I have in the forums: "Dynamically adding containers".

      However, I am using an object (note this object can change - is dynamic):

      public var dashboardDP:Object =
      {item:"dashboard", children: [
      {item:"vbox", id:"vbox 1", children: [
      {item:"panel", id:"panel 1", children: [
      {item:"hbox", id:"hbox 1", children: [
      {item:"view" id:"view 1"},
      {item:"view" id:"view 2"},
      {item:"view" id:"view 3"}
      {item:"hbox", id:"hbox 2", children: [
      {item:"view" id:"view 4"},
      {item:"panel", id:"panel 2", children: [
      {item:"vbox", id:"vbox 2", children: [
      {item:"view" id:"view 5"},
      {item:"view" id:"view 6"},

      And I want to loop through every child in this object but am struggling to do so :(

      e.g. the following loop will ony return the first child of the object:

      for(var i:int=0; i<dashboardDP.children.length; i++)
      // some code.....

      I want to advance this loop so that it "drills" into and retrieves / reads every child and sub child of each parent etc.....

      Is this possible???

      Any help would be much appreciated on this one.

      Thanks in advance,
        • 1. Looping through an objects children
          Recursion is the answer!

          Write a function that does what you want to do and then call that function from itself for each child.

          Also consider using "for each" rather than "for".

            Hi "xtempore" thanks for the fast reply!!!

            Just off the top of my head... I am using an Object type for "dashboardDP".
            Will this work as in your example to loop through and get all the children?

            I notoce you are using a type UIComponent and referencing UIComponent.children - will this work?

            I have train but am getting errors... with the line:
            for each (var c: UIComponent in comp.children) {
            when trying to access the ".children"

            Could you please expand?

            Thanks again,

            Kind Regards,
