I d suggest   document querySelector   rateRecipe btns-one-small   click      The above code assumes that the given element has both of those classes  otherwise  if the space is meant to imply an ancestor-descendant relationship   document querySelector   rateRecipe  btns-one-small   click      The method getElementsByClassName   takes a single class-name  rather than document querySelector   document querySelectorAll    which take a CSS selector   and you passed two  presumably class-names  to the method   References    document getElementsByClassName    document querySelector

If you want to click on all elements selected by some class  you can use this example  used on last fm on the Loved tracks page to Unlove all    var divs   document querySelectorAll   love-button love-button--loved      for  i   0  i  lt  divs length    i      divs i  click         With ES6 and Babel  cannot be run in the browser console directly       document querySelectorAll   love-button love-button--loved        forEach div   gt    div click
