solution if an ID and jQuery not available:

document.getElementsByTagName("button")[0].click();

If your page doesn't reference jQuery, you can simply find the element by its ID using javascript and attach click event to it as follows:

document.getElementById('mainbar').addEventListener("click", function() 
{
    console.log('main bar clicked');
});

Using jQuery:

$('#buttonid').click();
