Thank you!
Try this variation instead, it should work:
add_action('wp_footer', 'wp_footer_datepicker_range_fix', 9999);
function wp_footer_datepicker_range_fix() {
?>
<script>
(function($){
setTimeout(function(){
$('.asp_w .hasDatepicker').datepicker('option', 'yearRange', '-100:+100')
}, 500);
})(jQuery);
</script>
<?php
}
