use innerHTML

<script language="javascript">

function writeText(text){

<div id="mydiv">
test
</div>

Commented:
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.
