Method for divisionally transmitting and processing data between client and server in JavaScript language based asynchronous communication environment

摘要

The present invention relates to a method and a system for divisionally transmitting and processing of massive data between a client and a server in a JavaScript language-based asynchronous communication environment, and a client executing the same. According to the present invention, the method comprises the following steps of: a) a server dividing data into constant units and transmitting the divided data to a buffer memory of a client; b) the client transmitting a reception response to the server when a reception event representing that the divided data is received in the client occurs; c) the server receiving the reception response restarting data division transfer to the client; d) generating a timer in the client when the reception event occurs first; and e) the client processing the data received in the buffer memory every time interval set in the timer. According to the present invention, in data transmission and processing between the service and the client in the JavaScript based asynchronous communication environment, blocking effect of making the server waited without transmitting next data after transmission of the data is minimized. Moreover, in a large-size data transmission and processing process between the server and the client, since the number of data processing is reduced, the performance of the client is enhanced.
