How to highlight word under mouse in TextArea?

[Yu]

Hi,

I'd like to highlight the word under the mouse as the mouse pointer
move around in a TextArea. But I haven't found any API to do that?

Could you please help?

Thanks,

Yu

IMHO, there's no Javascript API to select only a part of text in text-
area... would be happy to be proven wrong.

I do not know the low level functions for doing this, but it is possible. We use a tool called CodeMirror on our project. It is a rich text area with code parser and syntax highlight.

There are methods it the api to select portion of text.

Hi Nicolas,

Fantastic reference.

And look at http://codemirror.net/jstest.html (search for "var" and
it's great).

Looking into the code, I found something of interest in js/editor.js
file.

setSelectionRange?
http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/client/ui/ValueBoxBase.html#setSelectionRange(int,
int)

The issue here is to "get the word under the mouse pointer".

A very ugly way (last resort) is to put each and every word under a
separate div. Duh me!
