Adds tags to highlight a webpage. It works around other interior tags, new paragraphs, bolded text, etc. Allows undo's. I wrote this because the other code I found for highlighting online is brittle, and works only on clean text, and not on the html inherent tree structure.
This class will change the html body content to add highlight color to strings copied from the website. It works around internal html tags that may otherwise hinder a naive highlighting approach. The first found matched strings are the ones highlighted. The three public facing functions are:
-
addCol(stringFromWebsite, stringHTMLcolor)
- This is the highlight functions. It finds the first match of stringFromWebsite in the HTML body, and colors it stringHTMLcolor.
-
undo()
- This undoes your previous highlight.
-
addContext(stringfromwebsite)
- This allows you to enter a large chunk of string from the website to act as a search substring, to help you highlight the correct string.
- **DO NOT USE. BROKEN and NOT DEBUGGED FOR THIS GENERAL TASK (You are welcome to though): **
Disclaimer: I do not code Javascript, so much of this might be very poorly written and inefficient. But whatever. :)
