Textarea Styles

[The Little Guy]

How would you take some text in a text area, then give it some style?

 

lets say I would like to make half of the text area italic and the other half bold, how would I do that?

Scrap my opening post, I decided to go with a div.

 

now I have a question, I am able to select text in the div, is it possible to get the first position of the selected text, and either the length, or the end position of the selected text?

 

example:

string = abcde

selected text = bc

start = 1

end = 2

length = 2

I couldn't figure out how you would find the start and the end, but I managed to get it to find the length. Here is some code, pretty self explanatory.

 

<script language="javascript">
function selectedText(id){

var sel = "";

try {
	sel = window.getSelection();
}
catch(e){
	try {
		sel = document.getSelection();
	}
	catch(e){
		try {
			sel = document.selection.createRange().text;
		}
		catch(e){
			alert("Could not get selection.\n"+e);
		}
	}
}
var selection = String(sel);
var length = selection.length;

alert(selection+"\n"+length);
}
</script>

<div id="select" name="select">This is some text.</div>
<br /><br />
<input type="submit" name="submit" value="Tell Me The Selected Text" onclick="javascript: selectedText('select')" />

I can get the length too, I just need to find a way to find the start position...

[The Little Guy]

to find the start position:

 

txt = window.getSelection();
txt.anchorOffset;

That only seems to work with window.getSelection().

But it does work.
