Question

I’m going to write an HTML5 app based on contents.
I planning to store the contents into the local Database.
Now, how can I schedule the updates?

Answer 1

There is a nice html 5 presentation here.

here is an example from there:

// use localStorage for persistent storage
// use sessionStorage for per tab storage
saveButton.addEventListener('click', function () {
  window.localStorage.setItem('value', area.value);
  window.localStorage.setItem('timestamp', (new Date()).getTime());
}, false);
textarea.value = window.localStorage.getItem('value');
