Your help needed!

[Vassil Catsarov]

Hello Folks
I'm completely new to JavaScripting, so your help will be invaluable.
How can I make a JavaScript execute itself periodocally, e.g. every second to check for example whether a particular RealVideo clip is playing and to initiate defferent behaviors - show clip info, hide the image window, etc. when a certain clip starts or stops playing.
Thank you!

Below there is a list with the properties, methods and events RealPlayer uses:

--***Properties***

-- Source:
-- Specifies the URL of the RealPlayer clip to play. The Source location can be pnm:, file: or http: protocol.

-- Controls:
-- Returns/Sets the visible components of the control. Valid CONTROLS include ALL, ControlPanel,
-- InfoVolumePanel, InfoPanel, StatusBar, PlayButton, StopButton, VolumeSlider, PositionSlider, PositionField,
-- StatusField, and ImageWindow.

-- Console:
-- Sets a console name used to link multiple control instances. All controls with the same console name work
-- together. For example, if you have multiple Play and Stop buttons on the same page, the console name would
-- enable them to control the same RealPlayer clip. Call this function once for each instance of the Play or Stop
-- button you want to link. The console name master links to all instances while unique links to no other instances.

-- Autostart:
-- Sets whether or not the control automatically starts playing once the source data is available. Valid values are
-- TRUE or FALSE.

-- NoLabels:
-- Suppresses the Title, Author, and Copyright label text in the controls window. The text strings in the fields are
-- still displayed.

-- AutoGotoURL:
-- Specifies how a URL will be handled. Valid values are TRUE or FALSE. TRUE indicates that the RealPlayer
-- ActiveX Control will automatically forward the URL event to the browser. FALSE indicates that the OnGotoURL
-- VBScript event will be sent instead.

To run a function every second:

setInterval ("yourFunction()", 1000); // run yourFunction every 1000 ms
