javascript - for each element type in body

javascript - for each element type in body

For example

For each div in body
          div.innerHtml = "poo"
next div

this is obviously psuedo code but demonstrates what i am trying to do.

Edit to share that it gives me tremendous joy to look at questions 9-years old and to see how far I've come and that this question still benefits others.

var elements = document.getElementsByTagName('div');

for (var i = 0; i < elements.length; i++) {
    elements[i].innerHTML = "foo";
}?

Live DEMO

If you want to look only in the <body>:

var elements = document.body.getElementsByTagName('div');

for (var i = 0; i < elements.length; i++) {
    elements[i].innerHTML = "foo";
}?
