Thanks in advance.

<script> var someSession = '<%= Session["SessionName"].ToString() %>'; alert(someSession) </script>

This code can be written to Aspx. If you want this in some js.file, you have two ways:

  • Create an aspx file that writes the full JS code and set the source of this file as Script src
  • Make a handler, process the JS file as aspx.

You can access your session variable as '<% = Session ["VariableName"]%>'

single quoted text will give the value of the session. one)

 <script> var session ='<%= Session["VariableName"]%>' </script>

2) you can take a hidden field and assign a value on the server;

hiddenfield.value = session ["xyz"]. tostring ();

 //and in script you access the hiddenfield like alert(document.getElementbyId("hiddenfield").value);

For me, this code worked in JavaScript like a charm!

 <%= session.getAttribute("variableName")%>

hope this helps ...

If you use VB code as a code, you need to use the bracket “()” instead of the square bracket “[]”.

Example for VB:

 <script type="text/javascript"> var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>'; </script>
