Many websites display a news ticker of one sort or another. A news ticker is a user interface element that displays a subset of a
list of items, cycling through them one at a time after a set interval. In December 2010 I wrote an article titled Use jQuery and ASP.NET to Build a News Ticker that
explored how to create your own news ticker widget using jQuery and ASP.NET. The news ticker’s content is defined as an unordered list
(<ul>) where each list item (<li>) represents a news headline. Once the ticker’s content is defined, having it cycle
through the head lines is as simple as calling the JavaScript function startTicker(id, numberToShow,
duration), which begins cycling the headlines in the unordered list with the specified id, showing numberToShow headlines
at a time and cycling to the next headline every duration number of milliseconds.
This ASP.NET tutorial shows how to enhance the news ticker to enable pausing and resuming. With these enhancements, the ticker can
be configured to automatically pause rotating its headlines when the user mouses over it, and to resume rotating them once the user
mouses out. Similarly, with a bit of additional markup and script you can add pause and play buttons to a ticker, allowing a user to
start and stop the ticker by clicking an image or button. To read the entire article, Pausing and Resuming the jQuery / ASP.NET News Ticker follow the link.
