<div id='foo'>0
</div>
<button onclick="document.getElementById('foo').replaceChild(document.createTextNode(i++),document.getElementById('foo').firstChild)">Hello</button>
<script type="text/javascript">
var i = 1;
</script>

And this works from a user input

<div id='foo'>0</div>
<button onclick="document.getElementById('foo').replaceChild(document.createTextNode(document.getElementById('userinput').value),document.getElementById('foo').firstChild)">Hello</button>
<input type="text" id="userinput">

Or this.

<div id='foo'>0</div>
<input  onkeyup="document.getElementById('foo').replaceChild(document.createTextNode(this.value),document.getElementById('foo').firstChild)">

innerHTML is non-standard, and document.all is positively harmful.

Use document.getElementId where possible (as it is the public standard). If you need support for Internet Explorer 4.0 (which is the only browser to support document.all but not document.getElementById) then you can do something like

if (document.getElementById) {
  obj = document.getElementById('foo');
} else if (document.all) {
  obj = document.all.foo;
}

However, given the market share of IE 4.0, it really isn't worth it.
