Remove HTML tags in a string using javascript

Hi, following code depicts how a string with HTML tags, is converted to a string without any tags.


<HTML> 
<HEAD> 
<TITLE> Remove HTML tags </TITLE> 
</HEAD> 
<BODY onload="demo();"> 
<SCRIPT LANGUAGE="JavaScript"> 
function demo()
{


var orignal= '<p align="Left"><b>I</b> <I>Rock!</I></p>'; 
var modified = orignal.replace(/(<([^>]+)>)/ig,""); 


alert(orignal);
alert(modified);


} 
</SCRIPT> 
</BODY> 
</HTML>


Keeps Coding! :)

Check whether a HTML control exists or not 


<!DOCTYPE html>
<html> 
<head> 
   <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
   <title>Check whether a control exists</title> 
</head> 



<body> 


   <script type="text/javascript">


       function check() {
           if (document.getElementById('btn_yasser')) {
               alert('Exists !');
           }
           else {
               alert('Not present');
           }
       }


   </script> 


   <input type="button" id="btn_yasser" value="click me" onClick="check();" /> 


</body> 


</html>
The same could be used for ASP controls.
Hope this helps.
