session handling in javascript

Hi everyone,
I wanted to know weather we can handle session using javascript.
Simply if i can test weather session is valid or not(i.e expired or still existing) does my work.
I was trying for it from past a week if anyone could help i would be happy.

Thanks and Regards,
Vidya Sagar Reddy.

Dont worry too much about it. I get them all day long.

re: session handling in javascript

javascript doesn't do sessions, it does cookies.

well....if u use ajax then you can create session variables (using php, asp.net,...).

good luck

Thanks a lot buddy
I have done an example using ajax but for a big web page if we use ajax call for every hit is a costly work i think so i am trying for an alternative and less costlier. Can u suggest any alternative.

I am using only one page and in the same page i am playing with the javascript (like say hide and seek) but the session is only this which should be taken care .

re: session handling in javascript

then just create cookies with javascript, i guess when the page loads make sure that the cookie(s) is(are) valid. cookies and sessions are pretty much the same, cookies are stored client-side and sessions are stored server-side.

re: session handling in javascript

would you be able to give an example of how i would use ajax to set an asp.net session variable?

re: session handling in javascript

in your asp.net page just create a session variable as u normally would

re: session handling in javascript

Sorry, i should have been a little more specific, i know that in my asp.net behind code (say c#) i would just go like this in a method:

what i was then wondering is how i could then use ajax or something in someway to call this from a javascript function. (i honestly dont know if this is possible, im pretty new to web dev, and i know little - nothing about ajax).

The reason why i wonder, is ive got an asp button, that when clicked i would like it to set the session variables, then open a new window (using javascript, window.open()) that will use those same session variables in some way.

re: session handling in javascript

the javascript doesn't get it directly. in your asp.net page u do all validation of the session there, then if its valid or not the page returns true or false (return statement is added by the programmer, you, and it returns whatever u tell it). then back in the javascript it will receive the true or false and based on that do whatever it is you wanted it to do, it will do that.

re: session handling in javascript

can javascript access session variable that define on vbcode in asp pages

re: session handling in javascript

If you return something back as output from your ASP page, then yes. For example, if you output the session variable in your ASP page, then it should be available to JavaScript in the XMLHttpObject's responseText property.
