Usage
for(init; condition; next) {
statement(s);
}
Parameters
init
An expression to evaluate before beginning the looping sequence, typically an assignment
expression. A
var statement is also permitted for this parameter.
condition An expression that evaluates to true or false. The condition is evaluated before
each loop iteration; the loop exits when the condition evaluates to
false.
next An expression to evaluate after each loop iteration; usually an assignment expression using
the
++ (increment) or -- (decrement) operators.
statement(s) An instruction or instructions to execute within the body of the loop.
Description
Statement; a loop construct that evaluates the init (initialize) expression once, and then begins a
looping sequence by which, as long as the
condition evaluates to true, statement is executed
and the next expression is evaluated.
Some properties cannot be enumerated by the
for or for..in actions. For example, the built-in
methods of the Array class (such as
Array.sort() and Array.reverse()) are not included in
the enumeration of an Array object, and movie clip properties, such as
_x and _y, are not
enumerated. In external class files, instance members are not enumerable; only dynamic and static
members are enumerable.
Example
The following example uses for to add the elements in an array:
my_array=new Array();
for(i=0; i<10; i++) {
my_array [i] = (i + 5)*10;
trace(my_array[i]);
}
The following results are displayed in the Output panel:
