[jQuery] Selecting only partial text from div

[jQuery] Selecting only partial text from div


I've a div which has lot of contents inside it...
I need to display only text of length less than 100letters..anything
more should be displayed only when I point to the word after it
For example: <div>This is the 100th word this is</div>
Here when I move my mouse from 'T' in This to 'h' in 100th I need to
display "This is the 100th"
and when I move my cursor to 'w' in word - I need to get "word this
is"
I heard about using mouse position to get this but I don't know how.
