Make Javascript regular expression case insensitive

Question

I\'m using a jquery function I found to find words in a div and highlight them. I\'m using this along with a search tool so the case is not always going to match the words

Answer 1

Just add "i":

pattern = new RegExp('(>[^<.]*)(' + what + ')([^<.]*)','gi'),

From MDN:

Regular expressions have four optional flags that allow for global and case insensitive searching. To indicate a global search, use the g flag. To indicate a case-insensitive search, use the i flag. To indicate a multi-line search, use the m flag. To perform a "sticky" search, that matches starting at the current position in the target string, use the y flag. These flags can be used separately or together in any order, and are included as part of the regular expression.
