Answer 1

Yes, you need to echo <script> tags and you can generate any Javascript you want:

<?php
echo '<script>';
if( have_rows('timeline') ):
    echo 'var foo = ['
    while ( have_rows('timeline') ) : the_row();
        echo '"'.the_sub_field('start_date').'",';
        echo '"'.the_sub_field('end_date').'",';
        echo '"'.the_sub_field('description').'",';
        echo '"'.the_sub_field('name').'"';
    endwhile;
    echo '];';
endif;
echo '</script>';
?>

It's quite simple to do this, really: just construct the array in php, and echo its json_encoded value:

<?php
$array = array();
if( have_rows('timeline') ) {
    while ( have_rows('timeline') ) : the_row();
        $array[] = array(
            the_sub_field('start_date'),
            the_sub_field('end_date'),
            the_sub_field('description'),
            the_sub_field('name')
        );
    endwhile;
    echo '<script> var theArray = '.json_encode($array).';</script>';
} ?>

Job done, you now have a JS variable called theArray, and its value will be an array of arrays, containing all of the data you need to create new Timesheet('timesheet', 2002, 2013, theArray);
