Techniques are disclosed for facilitating browser-based screen sharing using scripting computer language codes that are directly executable by a web browser. An example method comprises loading a presentation webpage in a presenter's web browser. The presentation webpage includes scripting language codes that are configured to cause the presenter's web browser to capture a screen image without requiring the presenter's web browser to load an applet. The method further includes receiving data indicative of the captured screen image from the presenter device, wherein the data is generated by the scripting language codes, processing the received data to form a processed screen image that is in an image format natively displayable to a viewer's web browser, and transmitting a viewer webpage including the processed screen image to the viewer's web browser.

Method and system for browser-based screen sharing

The Document Object Model (DOM) of a sampled web page is used to create a rule that extracts item-related data from web pages having a similar DOM structure to the sampled web page. In response to a user request for such a web page, the rule is retrieved from a data server based on the page's URL, and is applied to the DOM of the web page to extract item-identifying data. The item is then identified&#x2014;preferably by the data server&#x2014;by matching the item-identifying data to an item in a database. Supplemental information about the item is then retrieved from the database and supplied to the user's computer for viewing in conjunction with the requested page. In a preferred embodiment, the rule is retrieved from the data server and applied to the web page by a client application that runs in conjunction with a web browser.
