This script should work for you. (Place it where you want the text to go).
<script>
(function(D){
var text="Loading";
var scripts = D.getElementsByTagName('script');
var this_script = scripts[scripts.length - 1];
var container = D.createElement('span');
this_script.parentNode.insertBefore(container, this_script);
(function next(i){
container.innerHTML += text[i] + ' ';
if(++i < text.length)
setTimeout(function(){ next(i); }, 1000);
})(0);
})(document);
</script>
