Accessing Session information from Javascript

[Jeronimo Bertran]

Hi,

How can I access session information stored during the code behind from
within my javascript?

Example... in my javascript I have the following:

var url = "RenderPage.aspx";
document.all.MyFrame.contentWindow.navigate(url);


Where MyFrame is an IFrame..... inside the codebehind for RendePage.aspx I
am setting a session variable:

Session["MyVar"] = "hello";


I then want to be able to use this information from my javascript to fill a
field in my main form:



document.MyForm.elements[2].value = Session("MyVar"); // This doesn't
work.

Thanks a million,

Jeronimo

Hi,

Client-Side scripts cannot access Server-Side variables! Hence you cannot
access the server-side session object from your javascript.

I'd suggest that instead of savig that value to a session save it to a
hidden input field, so that the JavaScript can read the value from it.

ok, now... my problem is that the value that needs to be saved is generated
inside a page that lies inside a frame of the form that needs to know the
value.... how can I save the value to a hidden input field in the main
form? Or access the hidden input field in the child frame from my main
form?

Another option could be to have a hidden iframe and navigate to a page (via
javascript) that returns the session variable value (for instance, something
getSessionValue.aspx?var=varName).

The getSessionValue.aspx only needs to do the something like
Response.Write(Session(Request.QueryString["var"]))

Then, you can access via Javascript to inner value of that div

This option gives you session information at the moment, but you have to
deal with syncronization issues and javascript client programing.
