javascript - querySelectorAll didn't working but querySelector did

Question

Making simple extension for chrome. Second function didn't work when changing "querySelector" into "querySelectorAll".

  var ele2 = document.querySelectorAll(".view-count ");
   window.onload = function(){
        func2();
  }

function func2(){
    ele2.innerHTML = ele2.innerHTML.trim();
    ele2.innerHTML = ele2.innerHTML.slice(0, -14);
    ele2.textContent = "$" + ele2.innerHTML.replace(/ /g,' ');
    }

Solution :

for (x=0;x<ele2.length;x++){ele2[x].innerHTML = ele2[x].innerHTML.trim();}
for (x=0;x<ele2.length;x++){ele2[x].innerHTML = ele2[x].innerHTML.slice(0, -14);}
for (x=0;x<ele2.length;x++){ele2[x].textContent = "$" + ele2[x].innerHTML.replace(/&nbsp;/g,' ');}

Answer 1

querySelectorAll returns a collection of nodes as opposed to querySelector which returns a single node.
To get to a node in the collection you'll have to reference it via an index.

ele2[0].innerHTML = ele2[0].innerHTML.trim();
