Format a text in the textbox
<p>I am trying to format a selected text to bold inside a textbox but not happening. However, it is hapenning in a span/div. My code</p>

<pre><code>&lt;html&gt; 
&lt;head&gt; 
&lt;title&gt;Untitled Document&lt;/title&gt; 
&lt;script type="text/javascript"&gt; 
function FormatSelectedWord(txtBox,style) 
{ 

var selectedText = document.selection 
? document.selection.createRange().text 
: txtBox.value.substring(txtBox.selectionStart,txtBox.selectionEnd); 

if(selectedText!='') 
{ 
var newText='&lt;'+style+'&gt;'+selectedText+'&lt;/'+style+'&gt;'; 
txtBox.value=txtBox.value.replace(selectedText,newText) 
spOutput.innerHTML=txtBox.value; 
} 
} 
&lt;/script&gt; 
&lt;/head&gt; 
&lt;body&gt; 


&lt;input type="text" name="txtBox"&gt; &lt;/input&gt; 
&lt;input type="button" value="Bold" onclick="FormatSelectedWord(txtBox,'b')"&gt; 
&lt;span id="spOutput"&gt;&lt;/span&gt; 
&lt;/body&gt; 
&lt;/html&gt; 
</code></pre>

<p>Is it possible to do it insde a textbox. If so how?</p>

<p>Thanks</p>
