[jQuery] find text within the page

[jQuery] find text within the page


I'm looking for a way to locate keywords to help the end user out.
For instance, if I want to find the word "polar" then i'd like my
function to locate it, wrap it with a span, and assign it a function.
so far I can locate using a content filter and classname like this...
$(".keyword:contains('polar')")
But this selects the whole element (paragraph, div, whatever)
how do i focus in on JUST the text?
