Abstract: The traditional Web technology is difficult to realize data processing and deal with the progress of the synchronization information displaying on the Web at the same time. Especially in the case of unknowing the circumstances and the number of local content updates page, the problem is more protruding. For solving the problem, we use the calling way of recursive function to achieve system information asynchronously, expand the Web information system application ability in order to improve the expressive force of human-computer interaction, and display the image of process for the user. Compared with a traditional Web thread which serves only a single user, the experimental results show that the proposed technology can achieve more than one Web thread and serve a user at the same time.
