Array of Class Objects

I would like to know how to create an array of class type.



I have defined ODT class named "TextFieldClass" with two properties property1 and property2

To create an object of this class, I use ODT.Classes.New(" TextFieldClass");

Then I initialize each class items.

Ex:

myObj=ODT.Classes.New(" TextFieldClass");

myObj.property1="My Name";

myObj.property2="My Address";



But I want to create an array of type TextFieldClass. I could not find a direct method. I used indirect method:

var myArrayObj= new Array();



// Create 5 objects of TextFieldClass type



for(var count=0;count<5;count++)

{

     myArrayObj[count]=ODT.Classes.New(" TextFieldClass");

  }

// Now initialize individual elements as required.

myArray[0].property1= "Name1";

myArray[0].property2' "Address1"

myArray[1].property1= "Name2";

myArray[1].property2' "Address2"



Though this worked fine, I want to know if we have any direct way of defining array of objects something like:



var myArrayObj=new Array(ODT.Classes.New(" TextFieldClass"));



Alternate method could be (I did not try) to create another class and define new arrayObject of first type inside this second class!!!



(Note: Above code may have few errors, it is not compiled one. Only shows the concept)

    Hi,



    There's no way to initialize the entire array at once. You should initialize it item by item either in a loop, or in its contructor like this:

    var myArrayObj= new Array(ODT.Classes.New(" TextFieldClass"), ODT.Classes.New(" TextFieldClass"), ODT.Classes.New(" TextFieldClass"), ODT.Classes.New(" TextFieldClass")/*etc*/);

    Continuation of this same thread:



    I have declared new object as:

    var myObject=new Object();

    myObject.property1= something;

    myObject.property2= something;





    Now I want to create an array of myObject type.



    var myObjectArray = new Array();





    How do I create each array elements?

    I tried as below , but seems to be having problem.

    myObjectArray [0] = myObject;

    myObjectArray [1] = myObject;



    How we have to create each array elements? Do we need to say something like:

    myObjectArray [0] = new (myObject)



    Note that the class is not created using ODT. Object is directly created.

    Hi,



    You first need to define methods of your object as it is described in MSDN.

    After that, initialize each element of your array with a new instance of this object (new instances are created via 'new ObjectName()').
