        alert(session_value);

its giving "<%=Session["Test"]%>" alert result, Its not giving Session values

回答1:

You are using a wrong syntax that is for another version of razor. You can change it to:

alert('@Session["Test"]');

Notice the use of the @ sign. You can refer to this page for the proper syntax.

回答2:

ASP.NET thinks what you write is a plain string. Removing the quotation marks should do the trick if we're talking about an .aspx file.

<%Session["Test"] = "Welcome DS";%>

var session_value = <%=Session["Test"]%>;

回答3:

If you really need your session variable only in Javascript why donøt you use a client side Session variable?

for example the html5 sessionStorage

You can set it like this:

sessionStorage.myVariable = "myvalue";

and read it like this:

var x = sessionStorage.myVariable
