The problem I am having is targeting the text in the input tag in the HTML below with Button that is Copying that text (words). What do i need to change to the JS to get it to target that Input value?

I want to do this without using ID - as I plan on replicating this many many times and don't want to set up individual Id's for the Input tags.

If there is a way to refer to the Class - 'columns-small-8' - child element, then maybe that would work?

Thanks in advance

JS

<script> 

window.onload=function(){
let btns = document.getElementsByTagName("button")
Array.from(btns).forEach(ele => {
  ele.addEventListener("click", function() {
   jimsFunction(this)
  });
})  
function jimsFunction(input) {
  let x = input.previousElementSibling
  let ele = x.previousElementSibling
  ele.select()
  ele.setSelectionRange(0, 99999)
  navigator.clipboard.writeText(ele.value)
  alert("Copied: " + ele.value)
}}

</script>

HTML

       <div>
          <div class="row collapse">
            <div class="columns small-8">
              <input type="text" value="words" readonly>
            </div>
            <div class="columns small-2">
              <a class="button full-width secondary" href="www.google.com" 
              target="_blank">View</a>                                
            </div>
            <div class="columns small-2">
              <button type="button" class="button full-width secondary">Copy URL</button>
            </div>
          </div>
        </div>
