Detouring in scripting systems
A system described herein includes a receiver component that receives third party code for execution in a host environment, wherein the third party code corresponds to a dynamic programming language, and wherein the third party code has at least one object reference to a first object that is used by the third party code. A detouring component automatically replaces the first object referenced by the third party code with a proxy object such that the third party code at runtime calls the proxy object instead of the first object.
1. A method comprising the following computer-executable acts:
in a web browser, receiving an advertisement that is desirably displayed in the web browser, the advertisement comprising computer-executable code that is written in a dynamic programming language, the computer-executable code comprising a reference to an object, the object being a document object model object;
prior to executing the computer-executable code in the web browser, replacing the reference to the object with a reference to a proxy object; and
subsequent to replacing the reference to the object with the reference to the proxy object, executing the computer-executable code such that the computer-executable code calls the proxy object rather than the object.
2. The method of claim 1 , wherein the computer-executable code comprises a plurality of references to a respective plurality of objects, and further comprising replacing the plurality of references to the respective plurality of objects with a plurality of references to a respective plurality of proxy objects.
3. The method of claim 2 , wherein the plurality of objects are document object model objects.
4. The method of claim 1 , wherein the dynamic programming language is javascript.
5. The method of claim 1 , wherein the proxy object facilitates restricting access to a portion of a web page to the computer-executable code.
6. The method of claim 1 , further comprising using the proxy object to migrate an advertisement from a same domain iframe to a soft-cross-domain iframe.
7. The method of claim 1 , further comprising rendering the advertisement on a web page.
8. The method of claim 1 , wherein the advertisement is an interactive advertisement.
9. The method of claim 1 , wherein the advertisement is desirably displayed in the web browser together with at least one email of a user.
10. The method of claim 1 , wherein the proxy object restricts an amount of time that the advertisement is displayed in the web browser.
11. A system comprising the following computer executable components:
a processor; and
a memory that comprises a plurality of components that are executed by the processor, the plurality of components comprising:
a receiver component that receives an advertisement for display on a web page, the advertisement comprising third party code for execution in a web browser, wherein the third party code is written in a dynamic programming language, wherein the third party code has at least one object reference to a first object that is used by the third party code, the first object being a document object model object; and
a detouring component that automatically replaces the first object referenced by the third party code with a proxy object such that the third party code at runtime calls the proxy object instead of the first object.
12. The system of claim 11 , wherein the advertisement is an interactive advertisement.
13. The system of claim 11 , wherein the detouring component comprises:
a creator component that creates the proxy object; and
a replacer component that replaces the at least one object reference with the created proxy object.
14. The system of claim 11 , wherein the plurality of components further comprises a render component that renders the advertisement in the web browser based at least in part upon the received third party code.
15. The system of claim 11 , wherein the detouring component creates a plurality of proxy objects corresponding to a plurality of objects referenced by the third party code.
16. The system of claim 11 , wherein the dynamic programming language is javascript.
17. The system of claim 11 , wherein the proxy object facilitates restricting access to a portion of the web page to the third party code.
18. A computer readable data storage device comprising instructions that, when executed by a computer, perform the following acts:
in a web browser, calling in third party code that is to be executed in a web page as an advertisement, wherein the third party code is javascript code;
creating a proxy object in a java execution environment, wherein the proxy object is a proxy to a document object model object referenced in the third party code;
replacing the document object model object referenced in the third party code with the proxy object;
executing the third party code in an iframe; and
proxying a document object model operation through use of the proxy object.
