anchor array help 2

skills · Jul 10, 2003

I am trying to access the array of anchors. What I want to do is take either the name or id and assign it to a variable. This is used later on in an internal search engine. I am having a problem with null.

What I have now is this:

pdf_link = first_window.document.anchors;

Is it possible to compare pdf_link to a string of text?

Regard,

Jonathan

tags[x].name
tags[x].id

will give you a name or id for each link (it will be blank if you haven't named the link or given it an id)

<a href="somePage.htm" name="linkName" id="linkID">

ok, I don't get it.

It still doesn't like it.

I get a "id" is null or not an object. Same with the name.

Here is my code:

Code:

while (j < first_window.document.links.length)
            {  
               var pdf_link = &quot;&quot;;
               pdf_link = first_window.document.links[j];
               var pdf_link_text = &quot;&quot;;
               var tags = document.getElementsByTagName(&quot;a&quot;)
	       if (tags[j].name != null)
                  {
                     pdf_link_text = tags[j].name;
                  }
	       if (tags[j].id != null)
                  {
                     pdf_link_text = tags[j].id;
                  }
               alert(pdf_link_text);

What is wrong with this code?

pretty much everything is wrong with that code.

if you're saying that you want to extract the "id" from an <a> tag, here is how to do it:

var a = document.getElementsByTagName("a&quot

;
var sId = "";

for (var x = 0; x < a.length; x++) {
if (a[x].id) {
sId = a[x].id;
}
else {
sId = "no id value!"
}
alert(sId);
}

try { succeed(); } catch(E) { tryAgain(); }

That's it. It FINALLY works! I appreciate all your help with this.

Your code isn't even attempting my last few posts...

Run this code...

<script>
function anchors(){
tags = document.getElementsByTagName("a&quot

msg = ""
for(x=0; x<tags.length; x++){
if (tags[x].href != "&quot

{
msg += tags[x].href + " - " + tags[x].name + " - " + tags[x].id + "\n"
}
}
alert(msg)
}
</script>
<body onLoad="anchors()">

I have a slight problem with my coding.

It searches great, except that on a few pages, there is this:

<A NAME="2002">
<FONT SIZE="+3"><CENTER>2002</CENTER></FONT>
<HR SIZE=2 color="black">
<BR>

<TABLE BORDER=0 CELLSPACING=1 CELLPADDING=4 WIDTH=99%>
<TR><TD>2002_020</TD><TD><A HREF="fis\fis-02-020.pdf" ID="...">...</A></TD></TR>
<TR><TD>2002_019</TD><TD><A HREF="fis\fis-02-019.pdf" ID="...">...</A></TD></TR>

.

Here is the coding from before

var a = first_window.document.getElementsByTagName("a&quot

;
if (a[j].id)
{
pdf_link_text = a[j].id;
}
else
{
pdf_link_text = "no id value!";
}

My problem is that the (a name) is throwing off the link by one, or two, or how many ever (a name) there are.

What do need to have it skip over the (a name)s.

Look in my code again - you need something like this line...

if (tags[x].href != "&quot

{

I am not sure how that would fit into my code.

Here is what I have now:

Note this works except for those rare occasions I mentioned above.

var a = first_window.document.getElementsByTagName("a&quot

;
if (a[j].id)
{
pdf_link_text = a[j].id;
}
else
{
pdf_link_text = "no id value!";
}
if (pdf_link_text != "no id value!&quot

{
compare(pdf_link,pdf_link_text,find);
}

if (a[j].id && a[j].href != "")

Ok, that didn't work so I am going to make this easy and just post the whole code. Here goes:

function search(first,find)
{
var i = 0;
var first_window = window.open(first,"first_window","width=1,height=1,top=1700,left=1700&quot

;
while (first_window.document.readyState != "complete&quot

{
var waiting = 0;
}
while (k < first_window.document.links.length)
{
var pdf_link = "";
pdf_link = first_window.document.links[k];
var pdf_link_text = "";
var a = first_window.document.getElementsByTagName("a&quot

;

if ((a[k].id) && (a[k].href != "&quot

)

{
pdf_link_text = a[k].id;
}
else
{
pdf_link_text = "no id value!";
}
if (pdf_link_text != "no id value!&quot

{
compare(pdf_link,pdf_link_text,find);
}

k++;
}
first_window.close();
}

The code in green is the search part. The code in red is the file being searched. Somehow, pdf_link_text is being linked with the address of 2 down. The items in blue are throwing off the links.

Hopefully this may help.

Run this - it's working for me....

<script>
function showLinks(){
a = document.getElementsByTagName("a&quot

var msg = ""
for (x=0; x<a.length; x++){
if (a[x].href != "" && a[x].id != "&quot

{
msg += "\n" + x + " - HREF:" + a[x].href + " ---- ID:" + a[x].id + ">>>>> Name:" + a[x].name
}
else{
msg += "\n---not a link" + x + " - HREF:" + a[x].href + " ---- ID:" + a[x].id + ">>>>> Name:" + a[x].name
}
}
alert(msg)
}

I tried throwing in

if (a[x].href != "" && a[x].id != "&quot

{

into my code, and it still didn't work.

Also, what is with the

msg += "\n" + x + " - HREF:" + a[x].href + " ---- ID:" + a[x].id + ">>>>> Name:" + a[x].name

Is that just for testing purposes? Why don't you use my code?

if (a[j].href != "" && a[j].id != "&quot

{
pdf_link_text = a[j].id;
}
else
{
pdf_link_text = "no id value!";
}
if (pdf_link_text != "no id value!&quot

{
compare(pdf_link,pdf_link_text,find);
}

Any more suggestions?
