Asynchronous Partial Page Updates Based On Dynamic Dependency Calculation

摘要

A system and method for asynchronously updating a web page or web pages displayed on a computer. The method receives from the computer an event message that is generated as a response to an action by a user to change an object displayed on the web page. The method creates a dynamic dependency graph having a root node, and child nodes that depend upon the root node, and adds the object that generated the event message, or a reference to the object, to the dependency graph as the root node. In addition, the child nodes may add other child nodes. The method receives context information for other objects displayed on the web page, when a dependency exists between the object and the other objects. The method adds the other objects, or references to the other objects, to the dependency graph as the child nodes. The method traverses the dependency graph and sends update requests to the web page or web pages displayed on the computer, wherein the update requests are sent to the object associated with the root node, and the other objects associated with the child nodes.
