Abstract

Systems and methods for transferring a web content display from one container to another container are disclosed. A request to transfer a first web content display hosted in a first container having a first document object model (DOM) tree to a second container having a second DOM tree is received. The first web content display has a state comprising a plurality of state components. A second web content display hosted in the second container is created. If a first state component is dependent on a property of the first DOM tree associated with a host of the first web content display: the first state component is adjusted in the second web content display according to a corresponding property of the second DOM tree.

Claims

1. A method comprising:

receiving, at one or more processors, a request to transfer a first web content display hosted in a first container having a first document object model (DOM) tree to a second container having a second DOM tree, wherein the first web content display has a state comprising a plurality of state components;

creating, in response to the request, a second web content display hosted in the second container;

determining whether a first state component in the plurality of state components of the first web content display is dependent on a property of the first DOM tree associated with a host of the first web content display;

upon determining that the first state component is dependent on the property of the first DOM tree associated with the host of the first web content display;

adjusting, in the second web content display, the first state component according to a corresponding property of the second DOM tree;

upon determining that the first state component is independent of the property of the first DOM tree associated with the host of the first web content display;

copying, to the second web content display, the first state component of the first web content display; and

providing an output associated with the second web content display.

2. The method of claim 1, further comprising:

destroying, in response to the request, the first web content display.

3. The method of claim 1, wherein the first web content display comprises displayed web content or displayed application content.

4. The method of claim 3, wherein the plurality of state components comprises states of the displayed web content or the displayed application content.

5. The method of claim 1, wherein the property of the first DOM tree comprises having access to an event listener.

6. The method of claim 1, wherein the property of the first DOM tree comprises a transparency of a web content display hosted by a container having the first DOM tree.

7. The method of claim 1, wherein the property of the first DOM tree comprises a size of a web content display hosted by a container having the first DOM tree.

8. The method of claim 1, wherein the first container implements a platform of a browser, and wherein the second container implements the platform of the browser.

9. The method of claim 1, wherein the first container and the second container implement different browser applications.

10. The method of claim 1, wherein the first container comprises a first window, and wherein the second container comprises a second window.

11. The method of claim 1, wherein providing the output associated with the second web content display comprises displaying the second web content display or displaying an indication that the second web content display has been created.

12. A non-transitory computer-readable medium comprising instructions which, when executed by a computer, cause the computer to implement a method, the method comprising:

receiving a request to transfer a first web content display hosted in a first container having a first document object model (DOM) tree to a second container having a second DOM tree, wherein the first web content display has a state comprising a plurality of state components;

creating, in response to the request, a second web content display hosted in the second container;

determining whether a first state component in the plurality of state components of the first web content display is dependent on a property of the first DOM tree associated with a host of the first web content display;

upon determining that the first state component is dependent on the property of the first DOM tree associated with the host of the first web content display;

adjusting, in the second web content display, the first state component according to a corresponding property of the second DOM tree;

upon determining that the first state component is independent of the property of the first DOM tree associated with the host of the first web content display;

copying, to the second web content display, the first state component of the first web content display; and

destroying, in response to the request, the first web content display.

13. The computer-readable medium of claim 12, the method further comprising:

providing an output associated with the second web content display.

14. The computer-readable medium of claim 12, wherein the first web content display comprises displayed web content or displayed application content.

15. The computer-readable medium of claim 12, wherein the property of the first DOM tree comprises having access to an event listener.

16. The computer-readable medium of claim 12, wherein the property of the first DOM tree comprises a transparency of a web content display hosted by a container having the first DOM tree.

17. The computer-readable medium of claim 12, wherein the property of the first DOM tree comprises a size of a web content display hosted by a container having the first DOM tree.

18. The computer-readable medium of claim 12, wherein the first container implements a platform of a browser, and wherein the second container implements the platform of the browser.

19. The computer-readable medium of claim 12, wherein the first container and the second container implement different browser applications.

20. A system comprising:

one or more processors; and

a memory comprising instructions which, when executed by the one or more processors, cause the one or more processors to implement a method, the method comprising;

receiving, at the one or more processors, a request to transfer a first web content display hosted in a first container to a second container, wherein the first web content display has a state comprising a plurality of state components;

creating, in response to the request, a second web content display hosted in the second container;

determining whether a first state component in the plurality of state components of the first web content display is dependent on a property of the first container hosting the first web content display;

upon determining that the first state component is dependent on the property of the first container hosting the first web content display;

adjusting, in the second web content display, the first state component according to a corresponding property of the second container; and

upon determining that the first state component is independent of the property of the first container hosting the first web content display;

copying, to the second web content display, the first state component of the first web content display.
