AJAX Autosave functionality

Question

What\'s the best javascript library, or plugin or extension to a library, that has implemented autosaving functionality?

The specific need is to be able to \'save\'

Answer 1

I know that this question is old, but I would like to include a code that I like the most. I found it here: http://codetunnel.io/how-to-implement-autosave-in-your-web-app/

Here is the code:

var $status = $('#status'),
    $commentBox = $('#commentBox'),
    timeoutId;

$commentBox.keypress(function () { // or keyup to detect backspaces
    $status.attr('class', 'pending').text('changes pending');

    // If a timer was already started, clear it.
    if (timeoutId) clearTimeout(timeoutId);

    // Set timer that will save comment when it fires.
    timeoutId = setTimeout(function () {
        // Make ajax call to save data.
        $status.attr('class', 'saved').text('changes saved');
    }, 750);
});

It saves after the user stops writing for more than 750 milliseconds.

It also has a status letting the user know that the changes have been saved or not
