Flash/Actionscript Basics: If – Then – Else Statement Syntax

   Posted May 28, 2006 by David Kirk in Computer programming

Creating a basic if – then statement in flash or actionscript is easy. Here is the correct syntax.


The basic syntax is the following:

if (condition)
{
statement(s);
}

Here is an actual working example. If the variable userInput contains data, the value will be sent to the trace command.

if (userInput != undefined)
{
trace("Input is " + userInput);
}

Adding an else section is not much harder:

if (userInput != undefined)
{
trace("Input is " + userInput);
}
else
{
trace("Input is unknown" );
}
