[Javascript] Problem changing link's href property...

[Chris Nafziger]

I'm having a problem with the function below.  The first two lines do what
they are supposed to do just fine.  The third line does manage to change the
URL of the link, however it only works if I use the ID of zero that you see.
If I replace the the zero with the value assigned to the link's name
property, 'JumpTo', similar to the first two function lines, the error
'document.links.JumpTo' is null or not an object comes up.  Why can't I use
the link's name property value for the reference like I did with the images?


// Function that swaps two images and changes the link URL 
// when one of the swatch image's onMouseover event fires.

function imageOn(i)
    { 
    document.images["Unit"].src = UnitImages[i].src;
    document.images["UnitNumber"].src = UnitNumberImages[i].src;
    document.links[0].href = Page[i] 
    }

<a href="LinkToPage.asp" name="JumpTo" id="JumpTo">Link</a>
