If you add an undeclared function, dance , an error is generated, as shown in the following
example:
trace("");
craig.dance = true;
for (i in craig) {
trace("craig." + i + " = " + craig[i]);
}
/* output: **Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 14: There is
no property with the name 'dance'. craig.dance = true; Total ActionScript
Errors: 1 Reported Errors: 1 */
Add the dynamic keyword to the Person2 class, so that the first line appears as follows:
dynamic class Person2 {
Test the code again, and you see the following output:
craig.dance = true craig.age = 32 craig.name = Craiggers
