   <script src="<%=ResolveUrl("~/Scripts/jquery-1.4.1.min.js")%>" type="text/javascript"></script>
   <script src="<%=ResolveUrl("~/Scripts/jquery-ui-1.8.11.custom.min.js")%>" type="text/javascript"></script>
   <script src="<%=ResolveUrl("~/Scripts/jquery.validate.min.js")%>" type="text/javascript"></script>
   <script src="<%=ResolveUrl("~/Scripts/Purchase.js")%>" type="text/javascript"></script>

In the Purchase.js ,Jquery UI like calender,Jquery Validation has been added.Purchase.js is working properly.
