Assuming that you have valid HTML, the trivial solution is:
var hereTd = document.getEle mentById('here' );
var hereHref = hereTd.getEleme ntsByTagName('a ')[0].href;

Hi
I need to get all links from an document element. In sample below how
can i get link to "www.google.com " from element with ID="here"
RobG's solution should work fine. However, if you have a big list of
urls on the page and you want them all, you need to do this...
var links = document.getEle mentsByTagName( "a");
for(var i = 0; i<links.length ; i++) {
//Do whatever you want with the links
alert(links[i].href)
} http://developer.mozilla.org/en/docs...mentsByTagName

}
A caveat is that it you will get all anchors as well ( like <a
name="section3" )
For each document on the parsing stage two collections are being
automatically created:
document.links - with all links so all A with HREF attribute set
document.anchor s - all A with NAME attribute set
IMO on big documents, rather than using a rather resource consuming
getElementsByTa gName it is more straightforward to use these pre-
sorted collection:
var lnk = document.links;
var len = lnk.length;
for (var i=0; i<len; i++) {
// do what you need with
// lnk[i]
}
RobG, you are the man :). I owe you.
Thank you all for your time spent.

I'm trying to get an <a> element to gain the focus onload, but only get
back 'has no properties'.
Reading through this ng, its clear that unless the element is within a
form, this doesn't happen, but according to the w3 TR on html 4.01, the a
element can take onFocus commands, which to me means you can do
document.getElementById(element).focus() ?
I'm trying to get the focus to a specific paragraph, so the page scrolls to

Hi, I have an XmlDocument loaded from a memory stream. I set the document
element prefix in this way
XmlElement e = xDoc.DocumentElement;
e.Prefix = "abc"
When i simply write the document element to the command line it shows the
prefix. However, it does not persist in the XmlDoc so when i save the XmlDoc
into a file, the prefix is no longer there.
