Question

I need to create a news ticker that is updated via an RSS feed. Any ideas on how to implement this?

I would prefer Javascript but any language is acceptable.

Answer 1

There are are several good examples of this on this DynamicDrive page, although one of the requirements is that you can run PHP on your site. PHP here is used to fetch the actual feeds and allow your ticker to access them locally via an AJAX call.

There are several other projects out there built on JQuery, and the basic approach taken by each is:

• use a PHP (or ASP.net) script to fetch the feed to your server.

• access this local file via repeated AJAX calls, making use of setTimeout

• update the display (ticker) with latest data fetched

The file is fetched to your local server for the AJAX calls due to the Same Origin Policy:

It prevents a document or script loaded from one ‘origin’ from getting or setting properties of a document from a different ‘origin’.

Further examples include:

• JTicker from Jason’s Toolbox

• JQuery feed plugin – need to read the comments on this one, as code originally posted doesn’t seem to work out of the box
