title: webdriver.io - click on specific element where many elements exist
body: <p>I have many elements with a class name on a page. Can I use webdriver.io to click on a specific one in the array of Web Elements? </p>
  
  <p>If I do </p>
  
  <pre><code>browser
  .elements("perc-val")
  .then(function(res){
  
  })
  </code></pre>
  
  <p>I get an array of JSON objects. Can I call any further functions on these such as <code>click()</code>, or <code>setKeys()</code>?</p>
