Program that knows what elements you click on website

I'm trying to create a program where i can select the input boxes on website and list them into a listbox. i can use the C and delphi language but neither of them i can do this. I'm not trying to make a whole new browser, but just want to be able to do this. In a way it is like, when google chrome puts an orange box around the input boxes. it recognizes that it is a box you can type in. How do i recognize with a 开发者_如何学Goprogram what text box i have selected with my mouse? thx :)

You should look into GreaseMonkey for firefox. It allows you to run custom javascript on web sites, allowing you to transform pretty much whatever you want on the page.
