Systems and methods for hosted applications

摘要

Systems and methods for locally managing a user's interaction with content derived from web pages within the user interface of an application executing within a runtime provided by an application platform on a computing device in accordance with embodiments of the invention are disclosed. In many embodiments, a runtime provided by an application platform enables the execution of a non-natively implemented hosted application in which executing instructions in a scripting language within a background page control the downloading and modification of web content to create user interface pages for the hosted application.

主权项

1. A computing device configured to execute a hosted application, comprising:
a processor and storage, where an operating system is installed on the computing device that configures the processor to create a computing environment; an application platform application stored in the storage of the computing device, where the application platform application comprises:
a rendering engine process configured to:
render pages within the computing environment created by the operating system by interpreting instructions written in a rendering language; andimplement a virtual machine configured to execute instructions written in a scripting language; and an integration process that enables instructions executing within the virtual machine to modify the computing environment; at least one hosted application comprising:
a background page file including instructions in the scripting language: wherein the virtual machine is configured to parse the instructions in the scripting language contained within the background page file to configure the processor to:
download at least one remotely hosted file containing instructions in the rendering language for rendering a web page;modify the instructions written in the scripting language within the at least one downloaded file in accordance with a predetermined page modification rule to create at least one modified file;build a document object model (DOM) based upon at least the instructions in the at least one modified file; andmodify the DOM in accordance with a predetermined DOM modification rule to create a modified DOM; and wherein the rendering engine process is configured to render a user interface page based upon the modified DOM generated by the execution of the background page.
