Where is the error occurring?

You should always specify exact location/line of error in your source code and scenario.

For example in above code I assume you are getting error on con.style because con would be undefined because document.getElementById('<%=Confirm.ClientID>'); wont return any element.

Solution 1

when using mvc it does not require to use 'ClientID'.

try this

C#

var con=document.getElementById("#Submit");
