/*
Javascript functions to toggle the visibility of an IFrame containing a tooltip image. The IFrame will appear exactly
where it resides in the html.

Example of use:

Add this to the form where you want the tooltip to appear.
<a href = "#" onmouseover="return toggleTooltipOn('/img/tooltipJobNewAd.gif','tooltipIFrameHeading','250px','642px','lightyellow','padding:5px;')" onmouseout="return toggleTooltipOff('tooltipIFrameHeading')">Tips til gode overskrifter</a>
<iframe  id="tooltipIFrameHeading" frameborder="0" marginwidth="0" marginheight="0" scrolling=no class="tooltipIFrameHeading"></iframe>

toggleTooltipOn() parameters:
- imageUrl: Image to show inside IFrame
- IFrameName: The unique name of the IFrame
- IFrameHeight: The height of the IFrame window
- IFrameWidth: The width of the IFrame window
- IFrameBgColor: The background color of the IFrame
- IFrameBodyStyles: Here you can add css style attributes for the body tag of the
  IFrame window. E.g "padding: 5px; font-family: Verdana"

toggleTooltipOff() parameters:
- IFrameName: The unique name of the IFrame to be hidden

To function properly the Iframe must reference a css class with the
following attributes (You can also include your own):
.tooltipIFrameHeading{
    Z-INDEX: 999;
    POSITION: absolute;
    visibility:hidden;
    }
*/

    iFrame.style.top=iFrame.offsetTop;
    iFrame.style.left=iFrame.offsetLeft;
    iFrame.style.height = iFrameHeight;
    iFrame.style.width = iFrameWidth;

    //Get the content document of the IFrame
    var doc = iFrame.contentDocument;

    //Create the content of the IFrame and write it out
