I want to popup message after a server control is changed. I put a htmlinputhidden control on webpage and set "runat=server". When value of it changes, how to run javascript to popup message?
thank you in advance.

Just use the onchange event.<input type="hidden" value="whatever" onchange="alert('It changed.');"

Thank you. But I have to say it doesn't work. Because I set the control to runat=server, and there is no onchange event for it.jasonli at 2007-11-8 0:23:54 >
