Packagefever.commands
Classpublic class JSCommand
Implementscom.bourre.commands.Command

Defines and registers javascript command.

Allow runtime js method creation and call using the ExternalInterface feature.
If ExternalInterface.available is false commands are not executed.

2 ways to use :

All commands are registred in the JSCommandLocator to easily retreives them using their name.

As we want to control and keep the method name, we don't have to define the function name in javascript code.


Example 
  
    var command : JSCommand = new JSCommand( 
     'setTitle', 
     "( newtitle ){ document.title = newtitle; }" 
    );
    
    //result or param to pass 
    command.call( "newTitle" );

The function 'name_function' is automatically added during registration process.

Another way is to use the {

  
    var b : Boolean = JSCommandLocator.getInstance().register( 
     'setTitle', 
     "( newtitle ){ document.title = newtitle; }" 
    );
    
    if( b ) JSCommandLocator.getInstance().getCommand( name ).call( "newtitle" );
