Hi David, thanks for the reply.  Yes, it's populating the arr= ay as=20 expected.  Here's a better example script.  This is a simplif= ied=20 version of the actual script I'm using, but demonstrates the problem if= you run=20 it in ExtendScript Toolkit (it should pop up an alert box giving the length= of=20 the array but instead says ''undefined').
 
//~ Declare array (which will be populated with objects)
var textLineObjectArray =3D {};
 
var textLine=3D"Sample";
//~ Split string into array of characters
var textLineArray =3D textLine.split('');
//~ Iterate through array and for each character, create an object
for (var i =3D 0; i < textLineArray.length; i++){
     //~ Add  character name to object
       =20 textLineObjectArray[i]=3D{name:textLineArray[i]}
}
//~ output length of array of objects
alert(textLine1ObjectArray.length);
 
Can you see any problems with this?
 
Phil

Hi all, =20
 
I'm doing some scripting in AE, and need to iterate through an= Array of=20 Objects, so need to find out the number of items in the array in order = to=20 set up the loop.
 
I had expected to be able to get the number of items using=20 myArray.length, but this gives an 'undefined' error in ExtendSc= ript.
 
The array has been populated with a loop in the following manner:<= /div>
 
for (var i=3D0; i < myWidthValues.length; i++)
{
myArray[i].width=3DmyWidthValues[i];
myArray[i].height=3DmyHeightValues[i];
}
 
(this isn't the real code, just a simplified example)
 
And the array is functioning as expected (so for example=20 myArray[2].width gives the result I expect).
 
Is there a reason that an Array of Objects won't return a '= ;length'=20 value?
 
(I know this question would be better suited to a general javascri= pt=20 forum, but I've trawled internet forums to no avail, and thought I&= #39;d ask=20 here first in case it's a quirk specific to ExtendScript).
 
Any help much appreciated!
 
Phil
