case
Availability
Flash Player 4.
Usage
case expression : statement(s)
Parameters
expression
Any expression.
statement(s)
Any statement or sequence of statements.
Returns
Nothing.
Description
Statement; defines a condition for the
switch
statement. If the
expression
parameter equals the
expression
parameter of the
switch
statement using strict equality (
===
), then Flash Player will
execute statements in the
statement(s)
parameter until it encounters a
break
statement or the
end of the
switch
statement.
If you use the
case
statement outside a
switch
statement, it produces an error and the script
doesn’t compile.
Note: You should always end the statement(s) parameter with a break statement. If you omit the
break
statement from the
statement(s)
parameter, it continues executing with the next
case
statement instead of exiting the
switch
statement.
Example
The following example defines conditions for the switch statement
thisMonth
. If
thisMonth
equals the expression in the case statement, the statement executes.
var thisMonth:Number = new Date().getMonth();
switch (thisMonth) {
case 0 :
trace("January");
break;
case 1 :
trace("February");
break;
case 5 :
case 6 :
case 7 :
trace("Some summer month");
break;
case 8 :
trace("September");
break;
default :
trace("some other month");
}
