Abstract

A system and method for accelerated downloading of dynamic web pages. Initially, customized script library functions are downloaded from the server to the client browser as part of the page frameset. A page request from a user is received by the client browser and transmitted to the server. In turn, page data is fetched by the server from remote data sources and formatted to include library code for invoking associated library functions written in a script programming language, e.g., JavaScript. The formatted data pages is transmitted from the server to the client browser which calls the library functions that were previously downloaded to the client browser in response to the library code in the data pages. The appropriate library functions are invoked from the client browser to generate Hyper-Text Markup Language code that is written to a target frame. Finally, the Hyper-Text Markup Language code written to the target frame is rendered. The downloaded JavaScript library functions are therefore downloaded to the client side only once but accessed multiple times thereby increasing efficiency of downloading and reducing bandwidth. Faster page draw is achieved because of the limited amount of information or data that is repeatedly transferred to the client browser from the server.

Claims

1. A method for downloading dynamic web pages comprising the steps of:

downloading customized script library functions from the server to the client browser as part of a page;

receiving at the client browser a page request from the user;

transmitting the page request from the client browser to the server;

fetching data from remote data sources;

formatting the data pages including library code for invoking associated library functions;

transmitting the formatted data pages to the client browser;

calling the library functions that were previously downloaded to the client browser in response to the library code in the data pages;

invoking the library functions from the client browser to generate Hyper-Text Markup Language code written to a target frame; and

rendering the Hyper-Text Markup Language code written to the target frame.

2. The method in accordance with claim 1, wherein the script library functions are written in a script program language.

3. The method in accordance with claim 2, wherein the script program language is JavaScript.

4. The method in accordance with claim 1, wherein said transmitting step further comprises:

storing the downloaded page data in a multi-dimensional array in the client browser;

invoking a sorting function for sorting the data in the multi-dimensional array; and

rendering data from the sorted multi-dimensional array in response to a user'"'"'s sorting request.

5. The method in accordance with claim 1, wherein said transmitting step further comprises:

storing the downloaded page data in a multi-dimensional array in the client browser;

invoking a filtering function for filtering the data in the multi-dimensional array; and

rendering data from the filtered multi-dimensional array in response to a user'"'"'s filtering request.

6. The method in accordance with claim 4, wherein said transmitting step further comprises:

storing the downloaded page data in a multi-dimensional array in the client browser;

invoking a filtering function for filtering the data in the multi-dimensional array; and

rendering data from the filtered multi-dimensional array in response to a user'"'"'s filtering request.

7. A system for downloading dynamic web pages in response to a user'"'"'s page request, comprising:

a network;

a server electronically connected to the network for fetching data pages from remote data sources in response to the user'"'"'s page request, formatting the data pages including library code for invoking associated library functions; and

a client browser in electronic communication with the server through the network for receiving downloaded customized script library functions downloaded once from the server to the client browser as part of a page frameset, calling the library functions previously downloaded to the client browser in response to the library code in formatted data pages from the server, invoking the library functions from the client browser to generate HTML code written to a target frame, and rendering the HTML code written to the target frame.

8. The system in accordance with claim 7, wherein the network is one of the Internet, World Wide Web, Local Area Network, Wide Area Network, and Intranet.

9. The system in accordance with claim 7, wherein the library functions are a script programming language.

10. The system in accordance with claim 9, wherein the script programming language is JavaScript.
