Usage 2: A value from the array; either a native type or an object instance (including an Array
instance).
Usage 3: A property from the object; either a native type or an object instance (including an
Array instance).
Example
The following example shows two ways to create a new empty Array object; the first line uses
brackets ([]):
var my_array:Array = [];
var my_array:Array = new Array();
The following example creates an array called employee_array and uses the trace() statement
to send the elements to the Output panel. In the fourth line, an element in the array is
changed, and the fifth line sends the newly modified array to the Output panel:
var employee_array = ["Barbara", "George", "Mary"];
trace(employee_array); // output: Barbara,George,Mary
employee_array[2] = "Sam";
trace(employee_array); // output: Barbara,George,Sam
In the following example, the expression inside the brackets ("piece" + i ) is evaluated and
the result is used as the name of the variable to be retrieved from the my_mc movie clip. In this
example, the variable i must live on the same Timeline as the button. If the variable i is equal
to 5, for example, the value of the variable piece5 in the my_mc movie clip is displayed in the
Output panel:
myBtn_btn.onRelease = function() {
x = my_mc["piece"+i];
trace(x);
};
In the following example, the expression inside the brackets is evaluated, and the result is
used as the name of the variable to be retrieved from movie clip name_mc:
name_mc["A" + i];
If you are familiar with the Flash 4 ActionScript slash syntax, you can use the eval()
function to accomplish the same result:
eval("name_mc.A" & i);
You can use the following ActionScript to loop over all objects in the _root scope, which is
useful for debugging:
for (i in _root) {
trace(i+": "+_root[i]);
}
