How to update a jquery variable globally in HTML

For example, I have two copies of a page; both of which contain same jquery code. Something like:

$(document).ready(function () {
    var flag = 0;
    $('#anchor').click(function () {
        flag = 1;
    });
})

When I am on Page1 and clicked #anchor, the flag value changed to 1. Now if I return to Page2, I need the flag value to get modified, depending upon the action performed on Page 1; and vice versa. i.e. Modifying a variable on one page should update itself globally for all pages. How can this be done?

Any help is most appreciated. Thanks in advance

Thanks Mark. I will try with that.

Or – if it isn’t sensitive data, you can pass it through the query string.

But yeah – setting a cookie is probably the easiest method.

Thanks Jeff. I had this done successfully with cookies and jquery cookie plugin.
