How can I keep javascript objects alive in a multi-page app (browser independently)?
I know I can for example write a Chrome extension with a background page that would solve it, but is there a browser independent way for this?
One approach is to have your javascript code load the pages (via ‘ajax’ calls) and then replace the body of the html, or parts of it. This way, as far as the browser is concerned you’re still on the same “page”. You’ll have to make sure all the links within your website are void and instead of causing a browser page load, they actually trigger a javascript function. This is the way Facebook, for example, manages clicks on its website. See https://stackoverflow.com/a/7425870/562906
