Conditional to check whether Gravity Forms shortcode is on a page

functions.php

<?php
// conditional to check whether Gravity Forms shortcode is on a page
function lwd_has_gform() {
     global $post;
     $all_content = get_the_content();
     if (strpos($all_content,'[gravityform') !== false) {
    return true;
     } else {
    return false;
     }
}

Do you think another approach will be check if there is a gravityform JS enqueued or not? Just finding an approach I have come with yours. Thanks anyway
