Functions for working with a group of DOM elements

Let's now write a function that takes a group of elements selector and their new text as parameters. Let this function set new text to all elements, matching for the selector.

Let's implement the described function:

javascriptfunction setText(selector, text) {
  let elems = document.querySelectorAll(selector);
  
  for (let elem of elems) {
    elem.textContent = text;
  }
}

Let's test it for a group of the following elements:

html<p class="elem"></p>
<p class="elem"></p>
<p class="elem"></p>

Set new text for all elements with class elem:

javascriptsetText('.elem', 'text');
