Abstract

The present invention relates to a method for sharing and transferring data between different web browser frames (1, 2) which are served from different domains. This makes it possible to outsource services that would not be possible otherwise, owning to security limitations imposed by the web browser (101). The interaction between frames (1, 2) allows for the development of various services and products, like chat tools, customized floating toolbars, navigation inside a frame, advertising and many others. By circumventing browser imposed limitations which prevent frames served from one domain from communicating with other frames served from a different domain, the invention makes it possible for services to be provided by third parties, and it also makes

Claims

1. A method for transferring data between frames in a page of a web browser running on a user'"'"'s computer, the method comprising the steps of:

providing the frames within a common frame set;

associating a unique address with each frame; and

communicating between the frames in a manner determined by the technology present in the user'"'"'s computer.

2. The method of claim 1 utilizing a browser using HTML, a first frame communicating with a second frame by defining the HTML TARGET attribute to make the second frame the target.

3. The method of claim 2 utilized in a user'"'"'s computer which has the Flash program installed, further comprising the step of including a function in a JavaScript file in the web page, a first frame communicating with a second frame by using the GET_URL or the SetVariable Flash function, with a call to the function in the JavaScript file as the action and the second frame as the designated frame.

4. The method of claim 1 wherein a first frame communicates with a second frame as a result of an event in the first frame calling a function in the second frame.

11. The method of claim 1 utilized in a user'"'"'s computer which has the Flash program installed, further comprising the step of including a function in a JavaScript file in the web page, a first frame communicating with a second frame by using the GET_URL or the SetVariable Flash function, with a call to the function in the JavaScript file as the action and the second frame as the designated frame.

5. A method for transferring data between a plurality of frames of a web browser running on a user'"'"'s computer, said method comprising the steps of:

providing the frames within a common frame set;

associating a unique address with each frame; and

communicating from a first frame to a second frame by sending from the first frame to the frame set a message addressed to the second frame, transmitting the message from the frame set both frames, and accepting the message at the second frame when the message has the second frame'"'"'s address.

6. A structure for a page of a web browser running on a user'"'"'s computer, comprising:

a frame set;

a plurality of frames within the frame set, each frame having a unique address associated with it; and

executable code which achieves communication between the frames in a manner determined by the technology present in the user'"'"'s computer.

7. The structure of claim 6 utilized a browser using HTML, the executable code including a subprogram provided in a first frame communicating with a second frame, the subprogram defining the HTML TARGET attribute to make the second frame the target.

8. The structure of claim 7 utilized in a user'"'"'s computer which has the Flash program installed, the executable code including a function in a JavaScript file in the web page, and a subprogram in a first frame communicating with a second frame which uses the GET_URL or the SetVariable Flash function, with a call to the function in the JavaScript file as the action and the second frame as the designated frame.

9. The structure of claim 8 wherein the executable code includes a subprogram in a first frame responsive to the occurrence of an event to call a function in a second frame, to achieve communication from the first to the second frames upon the occurrence of an event.

12. The structure of any of claim 6 utilized in a user'"'"'s computer which has the Flash program installed, the executable code including a function in a JavaScript file in the web page, and a subprogram in a first frame communicating with a second frame which uses the GET_URL or the SetVariable Flash function, with a call to the function in the JavaScript file as the action and the second frame as the designated frame.

13. The structure of claim 12 wherein the executable code includes a subprogram in a first frame responsive to the occurrence of an event to call a function in a second frame, to achieve communication from the first to the second frames upon the occurrence of an event.

14. The structure of claim 7 wherein the executable code includes a subprogram in a first frame responsive to the occurrence of an event to call a function in a second frame, to achieve communication from the first to the second frames upon the occurrence of an event.

15. The structure of claim 6 wherein the executable code includes a subprogram in a first frame responsive to the occurrence of an event to call a function in a second frame, to achieve communication from the first to the second frames upon the occurrence of an event.

10. A structure for a page of a web browser running on a user'"'"'s computer, comprising:

a frame set;

a plurality of frames within the frame set, each frame having a unique address associated with it; and

executable code including a subprogram in a first frame which transmits from the first frame to the frame set a message addressed to a second frame, a subprogram in the frame set which transmits the message from the frame set to both frames, and a subprogram in the second frame which accepts the message at the second frame when the message has the second frame'"'"'s address.
