I am wondering if there is a simple (?) way to use JS to check if there is an update to the current page? Use AJAX to load the page and check against the current DOM? Is this possible?
Thanks,
Isaac

You could use XHR to load the page and then compare the page to the current, but it would be overkill. Serialising the DOM to do a string comparison would be a lot of unnecessary work for the JavaScript interpreter.
Instead, why not create a service, e.g. JSON, that lets you tell your page when something has updated instead of scraping the entire output?
