jQuery iframe popup and post form to parent

I want to create a popup search box. I am using thickbox iframe content. In the popup there are also some other form post when the popu开发者_Go百科p stays and save data. But i want when the main form (fm-form) is submitted then the post action is the parent and shows search result in the parent(popup closes). How can I do this? can i use any other popup?

Please see the above url and click on "New Search" to have an idea. Again thanks.

Set the target-attribute of the form to "_parent"
