In Flash 5 or later, you cannot use to dynamically set and retrieve the value of a
eval()
variable or instance name, because you cannot use on the left side of an equation. For
eval()
example, replace the code
eval ("var" + i) = "first";
with this:
this["var"+i] = "first"
or this:
set ("var" + i, "first");
Availability: ActionScript 1.0; Flash Player 5 - Flash Player 5 or later for full functionality.
You can use the function when exporting to Flash Player 4, but you must use slash
eval()
notation and can access only variables, not properties or objects.
