Abstract

A browser emulator is provided. An example browser emulator system includes a communications module to receive requests for web pages from a browser application, a document object model (DOM) interceptor to intercept an initial document object model (DOM) provided by the web application, an activator to activate a browser emulator, and a DOM manipulator to generate a modified DOM. A marked-up document that corresponds to the modified DOM includes an event interceptor that replaces JavaScript code associated with the original DOM provided by the web application.

Claims

1. A computer-implemented system comprising:

a communications module to receive a request for a web page;

a document object model (DOM) interceptor to intercept an original document object model (DOM) provided by a web application in response to the request;

an activator to activate a browser emulator, the browser emulator being a Java runtime configured to execute JavaScript code; and

a DOM manipulator to replace JavaScript code in the original DOM with an event interceptor to produce a modified DOM, the modified DOM corresponding to the requested web page, the event interceptor to facilitate communications over a specialized communications channel between a browser application that renders the web page and the browser emulator.

2. The system of claim 1, wherein the communications module is to:

generate the requested web page corresponding to the modified DOM; and

provide the web page to the browser application.

3. The system of claim 1, wherein the browser emulator is to:

receive an event from the browser application that renders the web page via the specialized communications channel;

execute JavaScript code associated with the event; and

propagate a result of the execution of the JavaScript code associated with the event to the browser application.

4. The system of claim 3, wherein the browser emulator is to update the modified DOM in response to the execution of the JavaScript code associated with the event.

5. The system of claim 3, wherein the event is associated with a user action.

6. The system of claim 5, wherein the result of the execution of the JavaScript code associated with the event is associated with a visual presentation of the web page.

7. The system of claim 1, wherein the browser emulator is in communication with a debugging module, the browser emulator to provide data associated with execution of the JavaScript code to the debugging module.

8. The system of claim 1, wherein the browser emulator is provided as part of an integrated development environment.

9. The system of claim 1, wherein the browser emulator and the browser application that renders the web page are provided on the same hardware.

10. The system of claim 1, wherein the event interceptor is provided according to a type of the browser application that renders the web page.

11. A computer-implemented method comprising:

using one or more processors to perform at least some of operations of;

receiving a request for a web page;

intercepting an original document object model (DOM) provided by a web application in response to the request;

activating a browser emulator, the browser emulator being a Java runtime configured to execute JavaScript code; and

replacing JavaScript code in the original DOM with an event interceptor to produce a modified DOM, the modified DOM corresponding to the requested web page, the event interceptor to facilitate communications over a specialized communications channel between a browser application that renders the web page and the browser emulator.

12. The method of claim 11, comprising:

generating the requested web page corresponding to the modified DOM; and

providing the web page to the browser application.

13. The method of claim 11, comprising:

receiving an event from the browser application that renders the web page via the specialized communications channel;

executing JavaScript code associated with the event; and

propagating a result of the execution of the JavaScript code associated with the event to the browser application.

14. The method of claim 13, comprising updating the modified DOM in response to the executing of the JavaScript code associated with the event.

15. The method of claim 13, wherein the event is associated with a user action.

16. The method of claim 15, wherein the result of the executing of the JavaScript code associated with the event is associated with a visual presentation of the web page.

17. The method of claim 13, comprising providing data associated with the executing of the JavaScript code to a debugging module.

18. The method of claim 13, wherein the executing of the JavaScript code is performed in an integrated development environment.

19. The method of claim 11, comprising:

determining a vendor-specific type of the browser application; and

replacing the JavaScript code in the original DOM with the event interceptor based on the vendor-specific type of the browser application.

20. A machine-readable medium having instruction data to cause a machine to perform operations comprising:

receive a request for a web page;

intercept an original document object model (DOM) provided by a web application in response to the request;

activate a browser emulator, the browser emulator being a Java runtime configured to execute JavaScript code; and

replace JavaScript code in the original DOM with an event interceptor to produce a modified DOM, the modified DOM corresponding to the requested web page, the event interceptor to facilitate communications over a specialized communications channel between a browser application that renders the web page and the browser emulator.
