if..else if
You can test for more than one condition using the
example, the following code not only tests whether the value of
whether the value of
if (x > 20)
{
trace("x is > 20");
}
else if (x < 0)
{
trace("x is negative");
}
If an or statement is followed by only one statement, the statement does not need to
if else
be enclosed in braces. For example, the following code does not use braces.
if (x > 0)
trace("x is positive");
else if (x < 0)
trace("x is negative");
else
trace("x is 0");
However, Adobe recommends that you always use braces because unexpected behavior can
occur if statements are later added to a conditional statement that lacks braces. For example,
in the following code the value of
evaluates to :
true
var x:int;
var positiveNums:int = 0;
if (x > 0)
trace("x is positive");
positiveNums++;
trace(positiveNums); // 1
