Save a Javascript variable between user interactions?

Question

Setting global variables in my js file doesn't seem to work. How can I set rails session variables from JavaScript?

I'd like a solution that doesn't use jQuery.

Edit: The solution is to use an HTML form containing hidden fields.

Global variables only live for the duration of a page view. Once the page is rerendered, they are reset to what their default values are.

If you need to keep the values, you need to use cookies or local storage. Other option is to submit them to the server with Ajax and have the server remember them and set the values when the page is rendered.

The page is not rerendered. The user clicks a button (causing me to need to save a variable) and then submits a form. During form submission, I need to have access to that variable.

So store the variable in a form hidden field and submit it to the server to use.
