Availability

Usage
break
Parameters
None.
Returns
Nothing.
Description
Statement; appears within a loop (
for
,
for..in
,
do while
or
while
) or within a block of
statements associated with a particular case within a
switch
statement. When used in a loop, the
break
statement instructs Flash to skip the rest of the loop body, stop the looping action, and
execute the statement following the loop statement. When used in a
switch
, the
break
statement
instructs Flash to skip the rest of the statements in that
case
block and jump to the first
statement following the enclosing
switch
statement.
In nested loops, the
break
statement only skips the rest of the immediate loop and does not break
out of the entire series of nested loops. For breaking out of an entire series of nested loops, see
try..catch..finally
.
Example
The following example uses the
break
statement to exit an otherwise infinite loop:
var i:Number = 0;
while (true) {
trace(i);
if (i>=10) {
break; // this will terminate/exit the loop
}
i++;
}
which writes the following output:
0
1
2
3
