Example
The following example returns an array with five elements:
var my_str:String = "P,A,T,S,Y";
var my_array:Array = my_str.split(",");
for (var i = 0; i<my_array.length; i++) {
trace(my_array[i]);
}
// output:
P
A
T
S
Y
The following example returns an array with two elements,
var my_str:String = "P,A,T,S,Y";
var my_array:Array = my_str.split(",", 2);
trace(my_array); // output: P,A
The following example shows that if you use an empty string ("") for the
parameter, each character in the string is placed as an element in the array:
var my_str:String = new String("Joe");
var my_array:Array = my_str.split("");
for (var i = 0; i<my_array.length; i++) {
trace(my_array[i]);
}
// output:
J
o
e
