HTML sinner can't repent!

**Cudabean** · May 25th, 2002, 01:31 PM

I tried running my code through the w3c validation service:
http://validator.w3.org/

It said that name="x" was an illegal attribute of <img>.

But, when I change it to id="x" the validator likes it, but then this JavaScript line fails:
document.x.src=picture;

I want validated code, but I also want my rollovers to work. Any ideas?

Why worry about validation? Do you know how much crap that gives me, but my stuff works in all browsers? I just don't see why it matters.

According to the code validation in HomeSite 4.5, it doesn't give me any errors with name="x", but it also doesn't show name as an attribute of the img tag.

I personally wouldn't worry about it.

Line 9, column 56:
<td><img src="http://www.vbshelf.com/corner.gif"></td>
^
Error: required attribute "ALT" not specified

You gotta be kidding me...

If you validate it you know it should work on all browsers, as long as they aint buggy. Anyway it's up to you if you want to validate or not

but here's how to get round the name/id thing:

Code:

//Modern W3C Compliant browsers:
if (document.getElementById) {
  document.getElementById('x').src=picture;
}
//Old NS browsers:
else if (document.layers) {
  document.layers['x'].src=picture;
}
//Old IE browsers:
else if (document.all) {
  document.all['x'].src=picture;
}

Oh by the way the ALT thing is required because if the image ain't found or the user is using a blind/braile/etc browser they will see nothing, so you should provide ALT so that will get shown instead of the picture.

although it is seriously annoying if you have images as bullets, and transparent spacer gifs. I mean, they still need an alt, which is pretty damn stupid

Hi. this is a spacer!
Hi there, I am a curve on the end of this table to make it look nicer! But I still need an alt tag

Well you can just make alt="", but the proper way to do images as bullets or spacers is to use CSS. If you want me to dig out the bullet thing I will. But for the spacers you can use:

Code:

  <div style="margin: 1px 3px 5px 2px;">This is spaced 1px down from the top, 3px in from the righ, 5px from the bottom and 2px from the right.</div>

Or you can use padding if you want to just indent the stuff inside the div/other element.

I decided to find it anyway

:

Code:

ul {
  list-style-image:url('Images/LI.png');
}

I think you can use it for li if you prefer, i.e. different classes for differnt 'li's in the same ul

Now that's wack...

Name is deprecated in favour of ID. The way the get around this (and for backwards compatibility) is to use id and name in the img tag.

Also, using document.images instead of document.x.src=picture;

Code:

document.images['x'].src=picture;
document.images[1].src=picture;

I gave up running my code through the W3C validator, it always finds new 'problems' that I wasn't even aware of.

and Rick, you know damn well we dont talk like that

**Rick Bull** · May 27th, 2002, 07:36 AM

Hey Punk, what other elements can you refer to in that method? I want to change the display of a div from/to block & none. I'm doing it using getElementById at the moment, is that the best way?

**punkpie_uk** · May 27th, 2002, 08:04 AM

theres a few different things you can do. One you use a lot is probably document.forms. Theres also getElementByName('elementName') and a few others

http://www.w3.org/TR/REC-DOM-Level-1...e-binding.html

Its about a third of way down

**Rick Bull** · May 27th, 2002, 09:45 AM

Thanks, that's just what I wanted. I've been wondering if there was a doc with all that info, but I'm too lazy to check the W3C site

If you don't give them an alt="", they show up (in lynx) as [IMAGE] rather than nothing, so imagine a blind person sitting there impatient as "image image image image image" is spoken aloud to him.

We are supposed to be getting nice little curvy tables features (more genericly, borders with rounded corners) in the next round of HTML/CSS. This means, if you use IE, don't count on ever correctly seeing a table again.

Oh wait, you can't correctly see anything now.

**Rick Bull** · May 28th, 2002, 05:13 PM

Yeah, IE makes writing web pages so hard. I think most people thing that it's right, and NS is wrong, but it's the other way around
