(I've send this question to webkit-dev mailing list, but have not got any
responses yet).
I am trying to write a JavaScript in Chrome to find the word user moused
over, which needs to convert the mouse coordination (x,y) into character
offset.
I know FireFox supports event.rangeOffset, which is the *character* offset
the cursor is at within the element. Given English word, using this offset,
I can find the previous and next spaces and know the word under the cursor.
But seems that Webkit (Chrome's layout engine) does not support
event.rangeOffset. Then, how to find the word user moused over? or how to
convert the event.clientX to the *character* offset within an element? My
understanding is that it must involve encoding/font/font size/style, but I
do not have clear idea on how it works.
Appreciate any input. It does not need to be complicated/completed (such as
to support RTL languages as well), I can start with English and/or some
other simple script such as Chinese.
Thanks for your help!
