input-change-with-delay.js

// Bind input change with a delay
$(document).on('input propertychange', 'textarea', function () { // Change 'textarea' to desired element
    var detailsElement = $(this),
        details = $(this).val();
    // If it's the propertychange event, make sure it's the value that changed.
    if (window.event && event.type == 'propertychange' && event.propertyName != 'value')
        return;

    // Clear any previously set timer before setting a fresh one
    window.clearTimeout($(this).data('timeout'));
    $(this).data('timeout', setTimeout(function () {
        // Do your thing here
    }, 5000)); // Change delay as desired. 5000 = 5s
});
