Interacting with Local webpage through Application in real time?

I want to interact with my local HTML page through my C++ application. Just like using java script console, we can edit a page in real time, e.g

document.getElementById('divlayer').style.visibility = 'hidden';

Similarly i want to call such functions in real time through my application.

Can you give me some idea if there is a way to accomplish this job?

I am using开发者_如何学C Google Chrome at the moment.

Do i need some plugin, but how can i make plugin to interact with my application then?

Also, i head about JQuery, can this be done using JQuery? Or do i have to try some server mecahnism may be using Ajax??

I know that you can control your IE browser with COM on Windows, and you can interact with the page with it. But I didn't try it with C++, I just use it with Python and it works well. May be you'd like to check it out.
