This class can be used in conjunction with a mouse pointer. The user hovers the cursor over an item, without clicking it, and a small box appears with supplementary information regarding the item being hovered over.
It must be used in conjunction with a few Javascript libraries that submit the page body HTML content to the server via AJAX.
On the server, the class parses the HTML content to lookup for known text expressions stored in a dictionary file in CSV format.
The text expressions found in the dictionary are replaced by links that make a popup window appear with the expressions meaning when the user drags the mouse over the links.
The processed HTML content is returned to the browser as part of the AJAX request response. |
