<a class="button checkout" data-no-turbolink="true" href="...">checkout</a>

Answer 1

You need to specify the index

document.getElementsByClassName("button checkout")[0].click()

function clickme(){
  document.getElementsByClassName("button checkout")[0].click()
}

function clicked(){
  alert('It works!!!!!!')
}

<a class="button checkout" data-no-turbolink="true" href="www.google.com" onclick="clicked()">checkout</a>
<hr/>
<button onclick="clickme()">Click div</button>
