JavaScript help

[fathom mountain]

I need to change the paragraphs with the class to the text I put into the textfield

[novel trellis]

var elementList = document.getElementsByClassName("hi");
for (i = 0; i < elementList.length; i++) {
  elementList[i].innerHTML = node;
}

Something along these lines

You get your array of elements, then edit each one. You can't edit the array all at once.
