fscommand2 Commands 225
The with statement is useful for accessing multiple items in a scope chain list simultaneously.
In the following example, the built-in
Math object is placed at the front of the scope chain.
Setting
Math as a default object resolves the identifiers cos, sin, and PI to Math.cos,
Math.sin, and Math.PI, respectively. The identifiers a, x, y, and r are not methods or
properties of the
Math object, but because they exist in the object activation scope of the
function
polar(), they resolve to the corresponding local variables.
function polar(r:Number):Void {
var a:Number, x:Number, y:Number;
with (Math) {
a = PI * pow(r, 2);
x = r * cos(PI);
y = r * sin(PI / 2);
}
trace("area = " + a);
trace("x = " + x);
trace("y = " + y);
} polar(3);
The following result is displayed in the Output panel.
area = 28.2743338823081
x = -3
y = 3
