210 Functions and Methods
Similarly, the following code placed on any frame does not work:
myWidth();
var myWidth:Function = function () {
trace(my_mc._width);
};
However, this code works properly:
var myWidth:Function = function () {
trace(my_mc._width);
};
myWidth();
When defining a named function, calling it in a frame script works, even though the
equivalent code with an anonymous function does not work:
// the following does work because you are calling a named function:
myWidth();
function myWidth() {
trace("foo");
}
// the following does not work because you are calling an anonymous
function:
myWidth();
var myWidth:Function = function () {
trace("foo");
};
For more information, see “Writing named functions” on page 207.
NOTE
You could also place myWidth() on any frame that is after the frame that contains the
myWidth function.
