Find string, highlight found string, scroll to found on iOS device

I found this script for a Find In Page / Highlight / ScrollTo feature on a page. On the iPhone, is there a way to style to popup so that it doe开发者_运维百科s not have "file://(null)" above the "Find Text"? Also, since I did not create this javascript and since I am not very good with javascript, how would I eliminate the "Found X matches" dialog?

I found a way to do this with the Wink Toolkit from http://www.winktoolkit.org/
