Javascript Click on Element by Class

Question

So I am writing a script that can be run on a page but I want to click on this element, unfortunately, it does not have an id to get and I am trying to use the .click() function on it, but it doesn't work, here's what I have, anyone know how to fix it? This is the only element in the class also

var classes = document.getElementsByClassName('rateRecipe btns-one-small'); var Rate = classes[0]; Rate.click(); 

Answer 1

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().
