jQuery to check the first charater of a link started with hash #

I came across an issue with an old wordpress site where the mobile menu did not close when a menu item link to internal page content because the url started with # hash.

So I worked out that you could close the menu suing jQuery by doing the following.

$('.mobile-button.active').click();

So this was the same as the user clicking the burger menu to close it. But then I needed to only do this when a link was clicked that started with # hash. The following was used.

jQuery(document).ready(function($) {
    $('a[href^="#"]').on('click', function(e) {
        // Prevent the default behavior of the link
        //e.preventDefault();

        // Get the href attribute of the clicked link
        var href = $(this).attr('href');

        // Check if the URL starts with '#'
        if (href.charAt(0) === '#') {
            // URL starts with '#', do something
            console.log('URL starting with "#" clicked');
            $('.mobile-button.active').click(); //go ahead and close the menu
        }
    });
});
