nodeValue: Showing null? (EZ)

milton747 · May 30, 2006

Hi folks,

I have a 'very' simple script to retrieve the node values.
nodeName comes back good. But value is null. Trying to
retrieve either New York or Los Angeles from HTML below.

Any suggestions welcome.
Thanks
Milton.

-- script and HTML below ----- IE 6

<HEAD>
<SCRIPT>
function ShowAll()
{
var ALLDOC = document.getElementsByTagName("*");

for(var i=0; i < ALLDOC.length; i++)
{
if(ALLDOC.nodeName != "NOBR") continue;

alert('nodeName = ' + ALLDOC.nodeName); // OK!
alert('nodeValue = ' + ALLDOC.nodeValue); // Null
}
}
</SCRIPT>

</HEAD>
<BODY BGCOLOR="#ffffff" ONLOAD='ShowAll()' >

<DIV

<DIV
ID="I205"
REGION="EAST"
CLASS=C266
>
<NOBR>New York</NOBR>
<BR>
</DIV>

<DIV
ID="I206"
REGION="WEST"
CLASS=C299
>
<NOBR>Los Angeles</NOBR>
<BR>
</DIV>

</DIV>
</BODY>

I think you need to drill down into the NOBR element's childNodes, as the text is probably in its own text node.

Hope this helps,
Dan

Code:

<HEAD>
<SCRIPT>
function ShowAll()
{
var ALLDOC = document.getElementsByTagName("*");

    for(var i=0; i < ALLDOC.length; i++)
    {
    if(ALLDOC[i].nodeName != "NOBR") continue;

    alert('nodeName  = ' + ALLDOC[i].nodeName);  // OK!
    alert('nodeValue = ' + ALLDOC[i].firstChild.nodeValue); // Null
    }
}
</SCRIPT>

</HEAD>
<BODY BGCOLOR="#ffffff" ONLOAD='ShowAll()' >

<DIV

<DIV ID="I205" REGION="EAST"CLASS=C266>
<NOBR>New York</NOBR>
<BR />
</DIV>

</BODY>

I don't know the answer but my good friend Google does.

Thanks j4606.
This was the final piece of a monster JS I've been developing.

Thanks.
Milton.

Isn't that exactly what I said?
