Abstract

An approach is provided for temporal registration of modifications in a document object model (DOM) and providing an efficient update to the DOM. A web content rendering engine processes and/or facilitates a processing of event data resulting from at least one interaction with a document object model to determine at least one modification to at least one node of the document object model. The web content rendering engine also causes a registration of the at least one modification with respect to a temporal parameter. Further, the web content rendering engine causes a generation of at least one content change result list for the document object model based, at least in part, on the registration. Furthermore, the web content rendering engine causes a transmission of the at least one content change result list to at least one proxy client for updating of the document object model.

Claims

1. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:

a processing of event data resulting from at least one interaction with a document object model to determine at least one modification to at least one node of the document object model;

a registration of the at least one modification with respect to a temporal parameter;

a generation of at least one content change result list for the document object model based, at least in part, on the registration; and

a transmission of the at least one content change result list to at least one proxy client for updating of the document object model.

2. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a size of the at least one content change result list.

3. A method of claim 1, wherein the at least one content change result list specifies, at least in part, one or more mutated nodes in the document object model.

4. A method of claim 3, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a number of the one or more mutated nodes.

5. A method of claim 3, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a ratio of the one or more mutated nodes to one or more unmutated nodes of the document object model.

6. A method of claim 3, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a sorting of the one or more mutated nodes by a temporal order based, at least in part, on the registration to cause, at least in part, the generation of the at least one content change result list.

7. A method of claim 3, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of the size of the at least one content change result list based, at least in part, on one or more respective sizes of one or more sub-trees associated with the one or more mutated nodes.

8. A method of claim 3, wherein the one or more mutated nodes are registered by one or more mutation event listeners for determining at least one least-sized sub-tree including the one or more mutated nodes.

9. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of a threshold value for a continuation of the registration of the at least one modification based, at least in part, on at least one content type associated with the document object model, available resources at the proxy client, a bandwidth for the transmission of the at least one content change result list, a ratio of a number of one or more nodes in the DOM before the at least one modification to a number of one or more nodes in the content change result list, or a combination thereof.

10. A method of claim 1, wherein the updating of the document object model includes causing, at least in part, a comparison of a first version of the document object model before the at least one interaction and a second version of the document object model after the at least one interaction.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

process and/or facilitate a processing of event data resulting from at least one

interaction with a document object model to determine at least one modification to at least one node of the document object model;

cause, at least in part, a registration of the at least one modification with respect to a temporal parameter;

cause, at least in part, a generation of at least one content change result list for the document object model based, at least in part, on the registration; and

cause, at least in part, a transmission of the at least one content change result list to at least one proxy client for updating of the document object model.

12. An apparatus of claim 11, wherein the apparatus is further caused to:

determine whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a size of the at least one content change result list.

13. An apparatus of claim 11, wherein the at least one content change result list specifies, at least in part, one or more mutated nodes in the document object model.

14. An apparatus of claim 13, wherein the apparatus is further caused to:

determine whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a number of the one or more mutated nodes.

15. An apparatus of claim 13, wherein the apparatus is further caused to:

determine whether to initiate a full update of the document object model or a partial update of the document object model based, at least in part, on a ratio of the one or more mutated nodes to one or more unmutated nodes of the document object model.

16. An apparatus of claim 13, wherein the apparatus is further caused to:

cause, at least in part, a sorting of the one or more mutated nodes by a temporal order based, at least in part, on the registration to cause, at least in part, the generation of the at least one content change result list.

17. An apparatus of claim 13, wherein the apparatus is further caused to:

determine the size of the at least one content change result list based, at least in part, on one or more respective sizes of one or more sub-trees associated with the one or more mutated nodes.

18. An apparatus of claim 13, wherein the one or more mutated nodes are registered by one or more mutation event listeners for determining at least one least-sized sub-tree including the one or more mutated nodes.

19. An apparatus of claim 11, wherein the apparatus is further caused to:

determine a threshold value for a continuation of the registration of the at least one modification based, at least in part, on at least one content type associated with the document object model, available resources at the proxy client, a bandwidth for the transmission of the at least one content change result list, a ratio of a number of one or more nodes in the DOM before the at least one modification to a number of one or more nodes in the content change result list, or a combination thereof.

20. An apparatus of claim 11, wherein the updating of the document object model includes causing, at least in part, a comparison of a first version of the document object model before the at least one interaction and a second version of the document object model after the at least one interaction.
