How to make a text wink effect in textarea?

[hongthanh168]

I want to make a text wink effect in textarea (only some words in a part can wink but not all). My textarea background is white. So I use textRange to select a part a text will wink and I do that:
var state=0;
var myTextRange;
/*
my code here to create myTextRange ...
/*
function wink()
{
if (state ==0)
{
myTextRange.execCommand("ForeColor", false, "red");
state =1;
}
else
{
myTextRange.execCommand("ForeColor", false, "white");
state =0;
}
}
//............................
<input type="button" value="wink" name="btWink" onclick = "setInterval("wink()",200)">

But it doesn't work. It seems the method execCommand("ForeColor", false, "white") doesn't work in textarea. Please help me! Thanks.

How about just setting the style color property to red and white instead?

textRange.style.color='red';

(Note I haven't tested this)

textRange.style.color='red';

It doesn't work.

See this link. Unfortunately, the code is compressed. If you can be bothered, you could look at the source code of the free, open-source text editors.
