Check this example of javascript isnull function :
Code:% if IsNull(rs("field")) then sVar = "" else sVar = rs("field") end if %> <% sVariable = "" & rs("field") %>
Try this example of javascript isnull function :
Code:<html> <head> <title> javascript isnull </title> <script language="JavaScript" src="./dynapisrc/dynapi.js"></script> <script language="Javascript"> dynapi.library.setPath('./dynapisrc/'); dynapi.library.include('dynapi.library'); dynapi.library.include('dynapi.functions'); dynapi.library.include('dynapi.api'); </script> </head> <body> <font face="boldl" size="3"> <script> var doc=document; j=dynapi.functions; doc.write('isNull: '+f.isNull('not null','is null')+'<br><br>'); </script> </font> </body> </html>
ISNULL() Replaces NULL with the specified replacement value, it can have 2 arguments, first is the field which is supposed to be checked whether it is NULL or not..Use the IsNull function to determine whether an expression contains a Null value.
