How to get value in the session in jQuery

Question

I'm a beginner in jQuery.
I want to set the values in an HTML page and I have to get them in another HTML page.

Here is the piece of code I am trying now:

To set the value in session:

$.session.set(userName, $("#uname").val());

To get the value from session:

$.session.get('userName');

`$.session` is either a plugin or you're confusing server-side and client-side coding — Dave Hogan, Mar 19 '13 at 21:16

In the first line, you set `userName` which seems to be a variable. Then in your get function, you attempt to get access to an object with a string that is not a variable. unless `var userName = userName`, then this scenario will never work. what does the first `userName` hold? — Ohgodwhy, Mar 19 '13 at 21:18
This is probably the plugin https://github.com/AlexChittock/JQuery-Session-Plugin ? Right? — Jan.J, Mar 19 '13 at 21:19
@Ohgodwhy - I'd suggest you type that up as an answer. It's a good catch, and I'm pretty sure it's what the OP's problem is. — Ben Barden, Mar 19 '13 at 21:20

Assuming you are using this plugin, you are misusing the .set method. .set must be passed the name of the key as a string as well as the value. I suppose you meant to write:

$.session.set("userName", $("#uname").val());

This sets the userName key in session storage to the value of the input, and allows you to retrieve it using:

$.session.get('userName');

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.
