JavaScript Find In Text File

I have been searching for a JavaScript "Find In Page" tool to pla开发者_C百科ce in a HTML file so that when I enter a search term and click submit, the script will search a TEXT file of my choice and find a match on the text page for the entry submitted. Can someone give me a hand? Thanks.

Use regex pattern matching to highlight the searched text
