Using Javascript to expand DIVs and go to anchor text

Question

I apologize that this question is so similar to "How can you check for a #hash in a URL using JavaScript?" but would appreciate your help with the following.

I would like to use Javascript to display text that is a) identified by an anchor. b) contained within 2 collapsed DIVs....ONLY WHEN the anchor is in the URL. Otherwise, the page should display with all DIVs collapsed.

Something like this:

if (theHashIsABC) {
  Expand 2 DIVs on the page and go to the anchor;
} else {
  just display the page;
}

Specifics: 1. Using IE7 2. DIVs ids to be expanded '8589' and '6212' out of several DIVs on the page 3. Anchor name is anchorABC

I have been told that it is not possible to expand some DIVs in IE7 so I am thinking I need to expand all DIVs on the page. [ I can expand just the 2 with a link within the page: <a class="jumplink" href="javascript:toggleBlock('6212');toggleBlock('8589')";link to expand DIVs</a> ]

This is what I have so far (in head section)...

if(window.location.hash = "anchorABC") { 

//this works with a button on the page that expand all divs 
function showAll(pstrClass) {
  var aElts = document.getElementsByTagName('div');
  setDisplay(pstrClass, aElts, 'show', 'Block');
  aElts = document.getElementsByTagName('span');
  setDisplay(pstrClass, aElts, 'show', 'Inline');
//would also like the page to move to the anchor

} else { 
  // just display the page


}

In advance, thank you for your time.
