Abstract

Systems and methods for user interface implementation for partial display update are disclosed. One embodiment of the method, which may be embodied on a system includes, in a response received from a web server, identifying, for a web page, a set of elements able to he updated partially as displayed without refreshing the user interface in its entirety, detecting, in the response, updated elements in the set of elements that have been updated from a value displayed in the user interface, and/or partially updating the user interface to reflect changes to the updated elements in the web page without refreshing other portions of the user interface.

Claims

1. A server, comprising:

means for, generating an HTTP response to an HTTP request, the HTTP response having a list identifying multiple elements of which at least one includes a value that is updated from a previous value;

means for, transmitting the HTTP response to a client device which generated the HTTP request;

wherein, the list in the HTTP response is parsed by the client device to identify the at least one element which includes the value that is updated and to render the updated value in a user interface of an application which made the HTTP request,

wherein the updated value is to be rendered without refreshing the user interface in its entirety.

2. The server of claim 1, w herein, the application interfaces with the Hadoop distributed the system (HDFS).

3. A method of partially updating displayed objects in a user interface, the method, comprising:

in a response received from a web server, identifying, for a web page, a set of elements able to be updated partially as displayed without refreshing the user interface in its entirety;

detecting, in the response, updated elements in the set of elements that have been updated from a value displayed in the user interface;

partially updating the user interface to reflect changes to the updated elements in the web page without refreshing other portions of the user interface.

4. The method of claim 3, further comprising, comparing received values for the set of elements with a set of previously stored values to detect the updated elements.

5. The method of claim 3, further comprising, generating a map of identifiers indicating which of the updated elements have been correspondingly updated in the user interface.

6. The method of claim 3, wherein, the set of elements are identified by a list of objects provided by the web server in the response.

7. The method of claim 3, further comprising,

detecting, in the response, new elements in addition to the set of elements previously received;

injecting the new elements for display in the user interface for the web page without changing display of other elements in the set of elements in the user interface.

8. The method of claim 3, further comprising,

detecting, in the response, elements removed from the set of elements previously received;

deleting the elements from the user interface for the web page to reflect removal from the set of elements without refreshing other elements in the set of elements in the user interface.

9. The method of claim 3, wherein, the response includes an HTTP response

10. The method of claim 3, wherein, the web page comprises multiple frames, each of the multiple frames including different applications which handle corresponding requests to the web server independent of the other applications loaded in other frames in the web page.

11. The method of claim 3, wherein, the partial updating occurs in a frame of the user interface, wherein, the frame contents are loaded independent of other frames in the web page.

12. The method of claim 3, wherein, the partial updating occurs in a frame of the user interface, wherein, the frame contents are unloaded independent of other frames in the web page.

13. The method of claim 3, wherein, the partial updating occurs in a frame of the user interface, wherein, results of the web server response are rendered in the frame of the web page in which an event triggering the web server response was generated, independent of other frames.

14. The method of claim 3, wherein, the frames include interactive web page features that are defined using HTML mark-ups.

15. The method of claim 3, wherein, the frame includes interactive web page features that are defined without using JavaScript.

16. The method of claim 10, wherein, each of the multiple frames maintains its own state independent of other frames in the web page.

17. The method of claim 10, wherein, shared resource among any of the multiple frames can be loaded once.

18. The method of claim 3, wherein, the web page interacts with a distributed file system.

19. The method of claim 18, wherein, the distributed file system is the Hadoop distributed file system.

20. A computer-readable storage medium having stored thereon instructions Which when executed by a processor causes a method of partially updating displayed objects in a user interface to be performed, the method, comprising:

in a response received from a web server, identifying, for a web page, a set of elements able to be updated partially as displayed without refreshing the user interface in its entirety;

detecting, in the response, updated elements in the set of elements that have been updated from a value displayed in the user interface;

partially updating the user interface to reflect changes to the updated elements in the web page without refreshing other portions of the user interface;

wherein, the web page interacts with a distributed file system.
