How to save (temporarily) form data?

There are, say, 10 fields on page1 and hyperlink to page2. Also there is hyperlink on page2 to page1. I fill 5 fields and click on the hyperlink. Then I click on the hyperlink on page2 and return to page1. Is it possible to save filled fields and how? Additional question: what if page2 modifies fields of page1. For example, creates new choice in multichoice field.

You can save filled fields using cookies via javascript after clicking on the link and before going to another page. For example it's possible to use this jQuery plugin jQuery-cookie. As documentations says:

A simple, lightweight jQuery plugin for reading, writing and deleting cookies.

Create session cookie:
$.cookie('the_cookie', 'the_value');

Create expiring cookie, 7 days from then:    
$.cookie('the_cookie', 'the_value', { expires: 7 });

Create expiring cookie, valid across entire page:    
$.cookie('the_cookie', 'the_value', { expires: 7, path: '/' });

Read cookie:    
$.cookie('the_cookie'); // => 'the_value'
$.cookie('not_existing'); // => null

Delete cookie by passing null as value:    
$.cookie('the_cookie', null);

Note: when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie.
