I have a PHP form for discussions. Each message has its own response button, which is dynamically generated. I'm using javascript in the button to make a response form visible at the bottom of the page, but I can't for the life of me get the page to jump down to the form once it's visible. This is a problem for pages that have a lot of discussions on it, as some users may not know to scroll down and will just think the button didn't work.

Here's what I have now for my button code:

<a href="#" onClick="changeVisibility(3,'responseForm')"><img src="images/reply.jpg" border=0 /></a>

The changeVisibility function looks like this:

function changeVisibility(parentID, elementID) {
  document.getElementById(elementID).style.visibility="visible";
  document.forms[0].parent_id.value=parentID;
  var el = document.getElementById(elementID);
  el.scrollIntoView(true);
}

In my form, I have a div whose id is set to responseForm. When clicking the button, the div does become visible, but the scrollIntoView is not working - I have to manually scroll down to see it. Any ideas?
