Abstract

Operation retrieval of webpage which includes content that actively changes on client side. When transmitting a webpage to a web browser, a web server detects an operation log acquisition function operating in the client's browser, detects web page text layout changes, and inserts and transmits a saved difference detection function. Web browser executes the difference detection function that was inserted in the web page that was received and saves the text layout of the webpage as a first text layout. Web browser executes the operation log acquisition function and generates and saves the operation log for web page, executes the difference detection function, compares text layout of webpage and first text layout, and if there is a disparity, makes a link between the disparity and the operation log. The log coordination server retrieves the operation of the web application, using the disparity that was linked to the operation log

Dependent claims

An operation reproduction method of a web application in a system configured by a web server, a web browser, a log connection server that stores an operation log on the web page, and a network that couples the web server, the web browser, and the log connection server to each other, the method comprising:

by the web server, inserting an operation log acquisition function that operates on the web browser and a difference detection function that detects and stores change of a document structure of the web page into the web page and transmitting the functions when the generated web page is transmitted to the web browser,
by the web browser, performing the received difference detection function inserted into the web page, to store the document structure of the web page as a first document structure,
performing the operation log acquisition function to generate and stores the operation log on the web page, and
performing the difference detection function to compare the document structure of the web page with the first document structure and if there is a difference, storing the difference so as to be associated with the operation log, and
by the log connection server, reproducing the operation using the stored operation log and the difference which is stored to be associated.

An operation reproduction system of a web application that reproduces an operation of a web application, the system comprising:

a web server device, a client device that executes a web browser, a log connection server device that stores an operation log on the web page, and a network that connects the web server device, the client device, and the log connection server device to each other,
wherein the web server device inserts an operation log acquisition function that operates on the web browser and a difference detection function that detects and stores change of a document structure of the web page and transmits the functions when the generated web page is transmitted to the web browser,
the web browser of the received client device performs the difference detection function inserted in the web page to store the document structure of the web page as a first document structure,
performs the operation log acquisition function to generate and store the operation log on the web page,
perform the difference detection function to compare the document structure of the web page with the first document structure and if there is a difference, stores the difference so as to be associated with the operation log, and
the log connection server device reproduces the operation using the stored operation log and the difference which is stored to be associated.
