Problem with HTML 4.01 Strict and JavaScript

[Don G]

I am trying to convert my HTML 4.01 Transitional code over to HTML 4.01
Strict (and later into XHTML), but when I go from Transitional to
Strict, part of my JavaScript stops working.

I have validated the HTML, both Transitional and Strict, so I am not
using any deprecated attributes. I have the image coded like this:

<img src="./images/spacer.gif" alt="spacer" name="myImage">

Then I have some JavaScript to change the image depending on the
thumbnail clicked. The JavaScript function is coded like this:

function setImage(imgNum) {
which_image_loaded = imgNum - 1;
if (which_image_loaded < 0)
which_image_loaded = NUMBER_OF_IMAGES - 1;
if (which_image_loaded == NUMBER_OF_IMAGES)
which_image_loaded = 0;
myImage.src = ImageNames[which_image_loaded];
}

Does anyone have a clue as to what the problem might be?

Thank you for your help,

Don

<img src="./images/spacer.gif" alt="spacer" name="myImage">
...
myImage.src = ImageNames[which_image_loaded];

AFAIK this is a proprietary (IE?) scheme you're using to refer to myImage.
Try
document.getElementById('myImage').src = ImageNames[which_image_loaded];

myImage. Try
document.getElementById('myImage').src = ImageNames[which_image_loaded];

Excellent! Thank you very much, that took care of it. This will also
allow me to switch from using the "name" attribute to using the "id"
attribute for images, thus bringing me closer to XHTML! I didn't
realize that what I was doing was proprietary since it worked fine in
Mozilla, but I guess Mozilla is more forgiving in Transitional than in
Strict.

Thanks again,

Don
