javascript thread: Changing a textarea's selection.
Hi chris
I dont know if this is what you need
its a 'scaled down' version of allan's excellent example and i only looked
at it with ie6.
It will render HTML tags around the stuff you've selected.
i guess if you want to implement this in a real app you need to validate
your html somehow to prevent the users from creating overlapping tags etc.
here it comes:
<html>
<head>
<script>
function makeBold()
{
var oSelection = document.selection.createRange( );
if(oSelection.text)
{
oSelection.text = '<b>' + oSelection.text + '</b>';
}
}
</script>
<title> New Document </title>
</head>
<body>
<button onClick=makeBold()>Bold</button>
<b>
<textarea name="someArea" cols="100" rows="3">This is some text in a
textarea</textarea>
</form>
</body>
</html>
hope this helps johannes
