How to redirect to edit post?

[Doppy]

Suppose that we are in another part of forum and I have this button. When I click on this button I would that it redirects me to page where I can modify post (it do this in my code):

But I want that when the button redirects me to "edit page" I see immediately the "edit form" with the value (something like this):

When I click on the button I use, to redirect at "edit page":

window.location.href = config.relative_path + "/topic/" + topic_id + "/" + topic.title;

Anyone can suggest how I can do this?
