You have a typo in the word alert and need quotes around the variable

 Response.Write("<input type='button' onclick='alert("<%=msg%>")' value='Hil'>")

did you get it to work? i just tested the exact code on my end and it's working...

why was the assisted question selected as a valid answer? it is syntactically incorrect both on the server side and on the javascript it generates, and will not work.

no..  doesn't like the alert. ??????????????????
console.log works  - I don't need the alert. just need to call a function.
Thought the other code was ok, sorry
thx again for your help

Looking at your question as to what you asked for, BM's answer http:Q_28502550.html#a40276080 is the correct way out of the two accepted.  The first answer by Deepak Subburajan will render as below
<input type="button" onclick="alert"1(" hello')' value="Hil">

Open in new window

and it should be
<input type="button" onclick="alert"(" hello")" value="Hil">

Open in new window

2 errors in the first.  the 1 before the (" hello and the single/double quoting is wrong.

Overall, you probably want to get in the habit of using button now instead of input type="button".  And keep your functions in your js.  Below would be my take on modernizing what we do in asp.  Static sample http://jsbin.com/gahozi/1/edit
<%
msg = "Hello"

%>

<!DOCTYPE html>
<html>
<head>
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
$(function(){
	$('.test').on('click',function(){
        var say=$(this).attr('data-item');
        alert(say);
	});
});	
</script>
  <meta charset="utf-8">
  <title>test</title>
</head>
<body>
<button class="test" data-item="hello">Hil</button>
<%
response.write "<button class='test' data-item='"&msg&"'>Hil</button>"
%>
</body>
</html>
