According to the present invention, a Java file is transcoded to a mobile terminal requesting a JavaScript file in consideration of the implementation environment of the mobile terminal, thereby increasing the speed of executing the coded JavaScript file in the mobile terminal. It relates to a script file providing method and system.

Currently commercially available mobile internet browsers are divided into two ways. Among them, there is a full browser method that downloads and parses html, css, images, JavaScript, etc. from a mobile terminal in the same way as a general PC, and then directly renders a screen. Alternatively, there is a web viewer method of processing a parsing and rendering process in a server and transmitting a resultant image file to a mobile terminal.

In the full browser method, since JavaScript and Flash are downloaded and executed directly on the mobile terminal, there is no need to download the data again, so if the time spent on the web site is long, the data traffic is less than that of the web viewer method. In addition, the user's input (mouse click, drag) can be handled directly from the mobile terminal, and the web viewer method sends input to the server, processes the input from the server, captures the screen, and sends the image again. In comparison, the reaction rate is faster.

However, the full browser method is a scripting language that executes source code in a browser, not a compile language, and the execution speed of JavaScript is slow due to the limitation of the performance of the mobile terminal in which the browser is executed. Has its drawbacks.
