in order to connect to db, you must use server side code,

if you need to do it in the javascript part,

you'll need to use the ActiveXObject("MSXML2.XMLHTTP")

Hi Alphauu

The isse with connect db is no problem..

My problem is I need to compare user input varaible with the value in DB and return an alert to the user if
a certain condition is not met..

can I solve this with asp script and javascript alone?

You can use AJAX for this. Once user clicks on the button, call the server side page and check the existance of date.

Please check the following example:
