Re: [flexcoders] selectedIndices are Strings???

Thanks Tom,

 

I believe array indices are ints, not
strings. However, I also believe that datagrid indices are strings, because
when I used the Array.sort() function on the DataGrid.selectedIndices array,
the order was all messed up. For example, "10" came before "2".
For that reason, I ended up writing a custom sort function to get around the
issue.

 

Thanks again!

 

Jim

Try either of these two options:

            for( var i:int; i <
arr.length; i++ )
            {
               
trace( arr[i] );
            }
            
//or

            for each( var i:int in
arr ) 
            {
               
trace( i );
            }

The for...in loop that you're using is for iterating over the properties of
objects, which it expects to evaluate as strings.  So, in your for...in
loop, the var i refers to the indices of the array, not the values you're
looking for which are the selectedIndices of your dg.  The for...each loop
above is new to AS3 and is the simplest way to do what you want. 

HTH,

Tom

I don't understand why DataGrid.selectedIndices
returns an array of Strings. I thought that indices were generally integers.
(For example, Array.indexOf returns an int.) 


Can anyone explain why the selected index of a
DataGrid is a String?


When "dgTest" is a DataGrid instance, the
following code generates a compiler error:


 


 


var arr:Array = dgTest.selectedIndices;


for(var i:int in arr){


// do something


}


 


The error that the compiler returns is as follows: 


"Implicit coercion of a value of type String to an
unrelated type int.  "
