File upload modifications for client side applications

Abstract:

Methods and systems are provided for a client computing device including a browser that renders a web page. Program code generates a mock upload event and a corresponding mock data transfer object for uploading data using the web page. The mock upload event and the corresponding mock data transfer object are propagated to an upload event listener of the web page and executed. Prior to generating the mock upload event and corresponding mock data transfer object, an embedded upload event listener may receive an upload event, read the upload event, drop the received upload event from an event handler pipeline, and call synchronously or asynchronously, code to perform logic on the received upload event for the generation of the mock upload event and a corresponding mock data transfer object.
