/****************************** RESIZE IFRAMES *******************************/
/*
    DYNAMICALLY CHANGE IFRAME HEIGHT BASED ON THE CONTENT IN THE IFRAME
    Copyright (c) 2008 BuilderFusion, Inc.
    
    Written by Jason LuBean
    
    Installation
    
    1.  Include this JavaScript file on the page where you have at least one IFRAME tag that 
        you want the height to be resized, based on the height of the content in the IFRAME tag.
    
    2.  Invoke the "bfResizeIframe" function once on the page.  This function will check every 10
        millisecond to see if there is a hash at the end of the URL in the form 
        "#bf_frameName_frameHeight" where "frameName" is replaced with the IFRAME name and
        "frameHeight" is replaced with the height (in pixels) of the page (an integer).  If that
        hash exists and the corresponding IFRAME exists, it will set the height of the FRAME.
    
    3.  For each IFRAME you want resized, insert a DIV tag in the HTML where you want to the IFRAME
        to be inserted.  Specify an ID for that tag.  There is no need for any content to be in the
        DIV tag because the code MUST dynamically add the IFRAME tag in the DIV tag in order for 
        the browser to allow the code resize the IFRAME.  After the DIV tag (or in the window.onload),
        invoke the "bfLoadResizeIframe" function:
        
             <div id="__ID__"></div>
             <script>
                var frameName = "dirFrame";
                var frameURL = "http://demo.builderfusion.com/bf/website/directory/index.jsp";
                var frameWidthPixels = 700;  
                var frameHeightPixels = 200; 
                bfLoadResizeIframe(frameName,frameURL,frameWidthPixels,frameHeightPixels);
             </script>
    4.  For each URL that is displayed in an IFRAME tag, attach/add an "onload" event listener
        (see "bfResizeParentFrameOnLoad" function) that does the following (if the "purl" 
        parameter exists on the query/search string):
        
            1.  Get the height of the page ("document.height" for Firefox; 
                "document.body.scrollHeight" for IE)
            2.  Get the "purl" value from the query string.  It will end with a hash in the form 
                "#bf_frameName" where "frameName" is replaced with the actual name of the IFRAME.
            3.  Modify the "purl" value to include a hash at the end in the form 
                "#bf_frameName_frameHeight" where "frameName" is replaced with the IFRAME name and
                "frameHeight" is replaced with the height (in pixels) of the page (an integer)
            4.  Set "window.top.location" to the modified "purl" value.
            
    The page including this script will 

    This code has been tested in IE 7.0 and Firefox 2.0.
