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.getEl ementById(id)){
document.getEle mentById(id).st yle.position = 'relative';
document.getEle mentById(id).st yle.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.getEle mentsByTagName( 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');ret urn false">Hide divs</a>

Which is, of course, invalid HTML.

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_b y_name(me,id, pluspic){

var tags = document.getEle mentsByName(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">

??

Does he mean the double use of an id?

AFAIK, document.getEle mentsByTagName only applies to form elements.

No, any DOM Node has getElementsByTa gName as a method. If you meant
getElementsByNa me, DOM 2 says:

getElementsByNa me
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. getElementsByTa gName('div'))
</script>

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

<script type="text/javascript">
alert(document. getElementsByNa me('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.getEle mentsByTagName( 'meta').length );

returns '3'.

http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/getelementsbyname.asp

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

This works


var tags = document.body.g etElementsByTag Name('tr');

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

and doesn't work with getElementsByNa me
