can't correct title, so if admin have some time , please change insef to instead.

<DIV id = "mi1">
<a class = "mi" href="javascript:alert('a');">java script </a>
<a class = "mi" href="#n">aaaaaaaaaaaaaa </a>
<a class = "mi" href="#n">ffffffffffff </a>
....
</DIV>

theThing = document.getElementById('mi1');
theThingChilds = theThing.getElementsByTagName("a");
for (i = 0; i <= theThingChilds.length-1; i++)
{
alert(theThingChilds[i])
// first element alerts "javascript:alert('a');", second ... ??? }
}

Thanks for help.

e.g.
theThing = document.getElementById('mi1');
theThingChilds = theThing.getElementsByTagName('a');
for (i=0; i<theThingChilds.length; i++) {
alert(theThingChilds[i].firstChild.nodeValue); // [node object] [node value]
}

To explain again: I want FF:"[ObjectHTMLAElement]", IE: "[Object]" to be returned in alert box.
Whay this does not work in my code ? It works if I do it with DIV element or some other element.

there is complet sample that returns wrong result:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html >
<head >
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>
<body >
<DIV id = "mi1" >

<a href="#n">hhhhhhhhhhhhm </a>
<a href="#n">hkgffhgjkgfh </a>
<a href="#n">fhgjkhgjkl </a>

</DIV>

<script language="javascript" type="text/javascript">
theThing = document.getElementById('mi1');
theThingChilds = theThing.getElementsByTagName('a');
for (i = 0; i <= theThingChilds.length-1; i++)
{
alert(theThingChilds[i]);
}
</script>
</body>
</html>

what is being returned is an HTML-object, it just seems that browsers treat them differently when using alert. You can still access its properties, as with a div or anything else, why do you need it to alert something nonsensical?

Seems you are right. Was hunting some other error, and come up with this, and things got even more complicated.
Note: document.write produces same thing as alert. And it is not browser thing as far as I know(IE and FF works the same)

Thanks for tip.
