Hide multiple elements by name

[Jochen Daum]

Hi!

I have a dynamically generated page (PHP), which contains an Explorer
like view of items. I would like to hide multiple <tr>'s by name, but
I can't figure out how thats done.

I have this code to hide one element by id

if (document.getElementById(id)){
document.getElementById(id).style.position = 'relative';
document.getElementById(id).style.display = 'none';
}

Anyone has a cod sample for looping through multiple elements and hide
them?

<script type="text/javascript">
function hide(t, id) {
var tags = document.getElementsByTagName(t);
for (var i = 0; i < tags.length; i++) {
if (tags[i].id == id) {
tags[i].style.display = 'none';
}
}
}
</script>

.....
<div id="sid">A</div>
<div id="impid">B</div>
<div id="sid">C</div>
<div id="impid">D</div>

.....
<a href="#" onclick="hide('div','sid');return false">Hide divs</a>

Which is, of course, invalid HTML.

What is invalid about that?

}
}
}
</script>

Wouldn't that also be working with any tag, if I did it like this. It
doesn't give me an error, but it doesn't work either:

function hide_elements_by_name(me,id, pluspic){

var tags = document.getElementsByName(id);
for (var i = 0; i < tags.length; i++) {
if (tags[i].name == id) {
tags[i].style.display = 'none';
}
}
}

and the tags being:

<tr name="xyz">

??

....
<div id="sid">A</div>
<div id="impid">B</div>
<div id="sid">C</div>
<div id="impid">D</div>

....
<a href="#" onclick="hide('div','sid');return false">Hide divs</a>

Does he mean the double use of an id?

AFAIK, document.getElementsByTagName only applies to form elements.

No, any DOM Node has getElementsByTagName as a method. If you meant
getElementsByName, DOM 2 says:

getElementsByName
With [HTML 4.01] documents, this method returns the (possibly empty)
collection of elements whose name value is given by elementName. In
[XHTML 1.0] documents, this methods only return the (possibly empty)
collection of form controls with matching name. This method is case
sensitive.

So yes and no, in XHTML it's only form controls. In HTML, it's
anything with a name attribute.

<div>test</div>
<script type="text/javascript">
alert(document.getElementsByTagName('div'))
</script>

IE6: alerts [object]
Opera 7: alerts [object nodeList]
NS7: alerts [object HTMLCollection]

<script type="text/javascript">
alert(document.getElementsByName('myDiv'))
</script>

Gives similar results.

I hunted a reference on MSDN but obviously didn't know where to hunt it :(

Using

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

<html lang="en" dir="ltr">
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<meta http-equiv="Content-Script-Type" content="text/javascript">
<meta http-equiv="Content-Style-Type" content="text/css">
...

and calling

alert( document.getElementsByTagName('meta').length );

returns '3'.

Like always, its not fully described. It returns a collection, but an
empty one.

This works
var tags = document.body.getElementsByTagName('tr');

for (var i = 0; i < tags.length; i++) {
if (tags[i].name == id) {
tags[i].style.display = 'none';
}
}

and doesn't work with getElementsByName
