Wordpress WooCommerce Grid / List toggle: How to trigger a button click?

The "WooCommerce Grid / List toggle"-plugin toggles the view of a list of products in WooCommerce. The last selection is stored in a cookie.

HTML-page contains:

<nav class="gridlist-toggle">
  <a href="#" id="grid" title="gridview">&#8862; <span>gridview</span></a>
  <a href="#" id="list" title="listview">&#8863; <span>listview</span></a>
</nav>
<ul class="products">
  <li class=" ...

Javascript function is:

jQuery(document).ready(function(){

    jQuery('#grid').click(function() {
        jQuery(this).addClass('active');
        jQuery('#list').removeClass('active');
        jQuery.cookie('gridcookie','grid', { path: '/' });
        jQuery('ul.products').fadeOut(300, function() {
            jQuery(this).addClass('grid').removeClass('list').fadeIn(300);
        });
        return false;
    });

    jQuery('#list').click(function() {
        jQuery(this).addClass('active');
        jQuery('#grid').removeClass('active');
        jQuery.cookie('gridcookie','list', { path: '/' });
        jQuery('ul.products').fadeOut(300, function() {
            jQuery(this).removeClass('grid').addClass('list').fadeIn(300);
        });
        return false;
    });

    if (jQuery.cookie('gridcookie')) {
        jQuery('ul.products, #gridlist-toggle').addClass(jQuery.cookie('gridcookie'));
    }

    if (jQuery.cookie('gridcookie') == 'grid') {
        jQuery('.gridlist-toggle #grid').addClass('active');
        jQuery('.gridlist-toggle #list').removeClass('active');
    }

    if (jQuery.cookie('gridcookie') == 'list') {
        jQuery('.gridlist-toggle #list').addClass('active');
        jQuery('.gridlist-toggle #grid').removeClass('active');
    }

    jQuery('#gridlist-toggle a').click(function(event) {
        event.preventDefault();
    });

});

How do I always get listview on the main shop page and always gridview on category pages disregarding the user's choice?
