Abstract

In one embodiment, a client application renders a structured document in a graphical user interface, determines whether a select place marker element in the structured document is viewable within the graphical user interface; if the select place marker element is viewable, the client application retrieves and render the data object associated with the place marker element.

Claims

1. A method comprising

in response to a scroll or resize event associated with a client application rendering a structured document in a graphical user interface, determining whether one or more place marker elements in the structured document is viewable within the graphical user interface, wherein each place marker element includes a fixed size and is an element rendered by the client application within the context of the structured document;

and

if the one or more place marker elements is viewable, dynamically modifying the structured document to cause the client application to retrieve data objects corresponding to the place marker elements from one or more remote hosts and load the data objects into the structured document.

2. The method of claim 1 further comprising registering a handler function with a client application for scroll or resize events.

3. The method of claim 1 wherein the structured document is an HTML document and wherein the place marker elements are HTML <

div>

elements.

4. The method of claim 1 wherein the structured document is an HTML document and wherein the place marker elements are included in elements of a table.

5. The method of claim 1 wherein the determining whether a select place marker element in the structured document is viewable within the graphical user interface is delayed by a prescribed period of time after the scroll or resize event.

6. The method of claim 1 wherein the dynamically modifying the structured document comprises setting respective source attributes of a predetermined set of place marker elements to uniform resource locators of a corresponding data object.

7. The method of claim 1 wherein the dynamically modifying the structured document comprises setting respective source attributes of a predetermined set of place marker elements to load the corresponding data object as a background image.

8. A non-transitory storage medium comprising executable instructions operative, when executed, to cause a processor to:

in response to a scroll or resize event associated with a client application rendering a structured document in a graphical user interface, determine whether one or more place marker elements in the structured document is viewable within the graphical user interface, wherein each place marker element includes a fixed size and is an element rendered by the client application within the context of the structured document; and

if the one or more place marker elements is viewable, dynamically modify the structured document to cause the client application to retrieve data objects corresponding to the place marker elements from one or more remote hosts and load the data objects into the structured document.

9. The non-transitory storage medium of claim 8 further comprising instructions operative to cause the processor to register a handler function with the client application for scroll or resize events.

10. The non-transitory storage medium of claim 8 wherein the structured document is an HTML document and wherein the place marker elements are HTML <

div>

elements.

11. The non-transitory storage medium of claim 8 wherein the structured document is an HTML document and wherein the place marker elements are included in elements of a table.

12. The non-transitory storage medium of claim 8 further comprising instructions operative to cause the processor to delay by a prescribed period of time after the scroll or resize event the determining whether a select place marker element in the structured document is viewable within the graphical user interface.

13. The non-transitory storage medium of claim 8, wherein to dynamically modify the structured document, the medium further comprises instructions operative to cause the processor to set respective source attributes of a predetermined set of place marker elements to uniform resource locators of a corresponding data object.

14. The non-transitory storage medium of claim 8, wherein to dynamically modify the structured document, the medium further comprises instructions operative to cause the processor to set respective source attributes of a predetermined set of place marker elements to load the corresponding data object as a background image.

15. An apparatus comprising:

a memory,

one or more processors;

computer program code comprising executable instructions operable, when executed, to cause the one or more processors to;

receive a request from a client application for a structured document including a plurality of embedded objects;

transmit a response including the structured document, wherein the structured document comprises code operative to cause the client application to initially retrieve and render a subset of the plurality of embedded objects, one or more place marker elements corresponding to a second subset of the plurality of embedded objects, wherein each place marker element includes a fixed size and is an element rendered by the client application within the context of the structured document, and an executable code object operative with the context of the client application and when executed by the client application operative to;

in response to a scroll or resize event associated with a client application, determine whether one or more place marker elements in the structured document is viewable within the graphical user interface; and

if the one or more place marker elements is viewable, dynamically modifying the structured document to cause the client application to retrieve the data objects from one or more remote hosts and load data objects corresponding to the place marker elements into the structured document.

16. The apparatus of claim 15 wherein the executable code object of the structured document is operative to register a handler function with the client application for scroll or resize events.

17. The apparatus of claim 15 wherein the structured document is an HTML document and wherein the place marker elements are HTML <

div>

elements.

18. The apparatus of claim 15 wherein the structured document is an HTML document and wherein the place marker elements are included in elements of a table.

19. The apparatus of claim 15 wherein the executable code object of the structured document is operative to delay by a prescribed period of time after the scroll or resize event the determining whether a select place marker element in the structured document is viewable within the graphical user interface.

20. The apparatus of claim 15, wherein to dynamically modify the structured document, wherein the executable code object of the structured document is operative to set respective source attributes of a predetermined set of place marker elements to load the corresponding data object as a background image.
