I'd just like to point out that document.contains is another way to do this.

document.contains is particularly useful if you have a web application whose components are rendered virtually before insertion into the DOM.

if you have that div's id, you can do it that way:

var myDiv = document.getElementById( 'turtles' );

if ( myDiv ) {
    //It exists
}

overwise, if it's a class, you'd better use a framework (jQuery here):

if ( $('.turtles').length > 0 ) {
  //it exists
}

Like this:

<script type="text/javascript">
function CheckExists() {
  var oDiv = document.getElementById("turtles");
  if (oDiv) {
    alert("exists");
  }
  else {
    alert("does not exist");
  }
}
</script>

The function must be located in bottom of page or called after page finished loading.
