Open a Bootstrap accordion control if its anchor is target on page load

openAnchorAccordion.js

// Opens accordion automatically if an accordion target is accessed from another page
// Assumes the accordion-group is the target linked to
function openAnchorAccordion() {
    if (window.location.hash) {
        var $target = $('body').find(window.location.hash);
        if ($target.hasClass('accordion-group')) {
            var $targetAccordion = $target.find('.collapse');
            $targetAccordion.collapse('show');
        }
    }
}

openAnchorAccordion();

$("body").on("click", "a", openHashAccordion);

I am using this code for bootstrap 4. I just want to open that accordion tab on load. Placed it in window.onload

if (window.location.hash) {
                var jQuerytarget = jQuery('body').find(window.location.hash);
                if (jQuerytarget.hasClass('collapse')) {
                    var jQuerytargetAccordion = jQuerytarget.find('.collapse');
                    jQuerytarget.collapse('show');
                }
}
