Javascript find and scroll to text

问题:

I need a bit of Javascript that will find some text in the html page and then scroll to that point.

So something like "Are you a Lib Dem or Tory supporter and how do you feel about the deal?" would scroll down to the bottom of the page for this bbc news page: http://news.bbc.co.uk/1/hi/uk_politics/election_2010/8676607.stm

Im hoping there is a built in function for both the find text and scroll.

Try this. It works on the site you provided:

$(window).scrollTop($("*:contains('Are you a Lib Dem or Tory'):last").offset().top);

It finds last, deepest element that contains given phrase on the page and scrolls to it.
