Hi All,

I have a rather complicated problem.
I use following function to display a hyperlink:

a="<"+"a href='";
b3="<"+"a href='http://nww.";
L="</"+'a><br>';

function h(a){document.writeln(a)}
function HN(link,tekst){target=telt();if
(wi==1)target="_top";h(b3+link+"'"+tag+target+"'"+"onclick='n(\""+target+"\",\""+"http://nww."+link+"\",\""+tekst+"\")'"+">"+tekst+L)}

Now I need an additional option to store a filename like:
function HN(link,tekst, filename)

The function HN should be rearranged that when I click this hyperlink
the filename gets stored to the clipboard, so I can release it with
Ctrl-V.

For Example:
HN('nix.nothing.int/WHERE/2005','My
Hyperlink','NIX.NOTHING.TEXT.20050723.')

Where the last part: NIX.NOTHING.TEXT.20050723. is the part which needs
to be copied to the clipboard.

Anyone knows how I should change the function HN to get this done?
Or is it not possible?

Regards

function HN(link, tekst, clipdata) {

   if (window.clipboardData) {
       window.clipboardData.setData('text', clipdata);
   }
   ...
}

Janwillem,

Thanks for the help but where exactly should I add this piece of code?
Like this?

function HN(link,tekst,clipdata){
    // IE only
    if (window.clipboardData) {
        window.clipboardData.setData('text', clipdata);
{target=telt();if
(wi==1)target="_top";h(b3+link+"'"+tag+target+"'"+"onclick='n(\""+target+"\"
,\""+"http://nww."+link+"\",\""+tekst+"\")'"+">"+tekst+L)}
}

No, because this will render the function useless to other browsers then IE.
The only part that needs to be excluded from other browsers is the
window.clipboardData bit. Take the code I have shown you before and insert
the original function body below it:

function HN(link,tekst,clipdata){
    // IE only
    if (window.clipboardData) {
       window.clipboardData.setData('text', clipdata);
   }

   // Original function body
   target=telt();

  // I assume wi is defined somewhere?
  if (wi==1) {
       target="_top";
   }
   h(....);
}

I tried the code listed below but it doesn't work:

function HN(link,tekst,clipdata){
    // IE only
    if (window.clipboardData) {
       window.clipboardData.setData('text', clipdata);
   }

   // Original function body
    {target=telt();
    if (wi==1)target="_top";

h(b3+link+"'"+tag+target+"'"+"onclick='n(\""+target+"\",\""+"http://nww."+li
nk+"\",\""+tekst+"\")'"+">"+tekst+L);
}

What went wrong?

You added an erroneous opening brace:

{target=telt();

This should be:

target=telt();

Please look again closely to the example in my previous reply.

Ok, tried again, the function is working but all text after where I run it
on the age is missing.

function HN(link,tekst,clipdata){
    // IE only
    if (window.clipboardData) {
       window.clipboardData.setData('text', clipdata);
   }

   // Original function body
   target=telt();

  // I assume wi is defined somewhere?
  if (wi==1) {
       target="_top";
   }

h(b3+link+"'"+tag+target+"'"+"onclick='n(\""+target+"\",\""+"http://nww."+li
nk+"\",\""+tekst+"\")'"+">"+tekst+L);
}

HN('nix.com/2005/','My Daily Report','DAILY.REPORT.')
------> after this all code on the page is missing....

Let's breakdown the function:

> target=telt();

Is the telt() function correctly defined?

> if (wi==1) {

Is wi defined as a global variable?

> h(b3+link+"'"+tag+target+"'"+"onclick='n(\""+target+"\",\""+
> "http://nww."+link+"\",\""+tekst+"\")'"+">"+tekst+L);

Is the h() function correctly defined?

Are the following variables globally defined:

b3
tag
L

Note that when variables not defined globally, should be defined in the
function itself.

BTW, a good JS debugging tool is FireFox's javascript console.

Everything was working fine until I entered the copy clipboard code.

b3 = "<"+"a href='http://nww.";
tag = "target='"
L = "</"+'a><br>';
tel=0;function telt(){tel++;return tel};

I tried to use Firefox JS console, but how do I check a complete html-file?

So everything works fine again when you remove the clipboard code?

Just call the script in FireFox, then look into the JS console to see if
there are errors.

That is: call the page that includes the script in FireFox. If this doesn't
bring up errors, then post an URL where the page can be viewed somewhere.

Got three time the error: Dialog has no properties

and this one (I don't know what it means):
Error: uncaught exception: [Exception... "Component returned failure
code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMWindowInternal.focus]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
chrome://global/content/bindings/tabbrowser.xml :: setFocus :: line
638"  data: no]

Do you programmatically create a popup window anywhere in your code? Does
the script work when you remove the window.clipboardData bit?

The following code works without any problems in both IE and FireFox:

<html>
<head>
<title> New Document </title>
<script type="text/javascript">
function test(text, clipdata) {
   if (window.clipboardData) {
       window.clipboardData.setData('text', clipdata);
   }
   document.write(text);
}
</script>
</head>

<body>
<script>test('Hello', 'World');</script>
</body>
</html>

Are you doing something simular or are you calling the HN function when the
page is already done loading? In that case it's important that the h()
function does not use document.write as this will wipe out the initial page
including the scripts.

The problem appears to be that the window.clipboardData.setData() function
expects a string as the second argument and sometimes it's an integer.

Changing the call into:

if (window.clipboardData) {
   window.clipboardData.setData('text', '' + clipdata);
}

will fix this...

With this new code it now works fine:

function setClip(clipdata) {
    if (window.clipboardData) {
      window.clipboardData.setData('text', clipdata);
   }
}

function HN(link,tekst,clipdata) {
    target=telt();
    if (wi==1) {
        target="_top";
    }

    text2write  = b3 + link + "'" + tag + target + "'";
    text2write += "onclick='setClip(\"" + clipdata + "\");";
    text2write +=
"n(\""+target+"\",\""+"http://www."+link+"\",\""+tekst+"\")'";
    text2write += ">" + tekst + L;
   
    h(text2write);
}

thanks a lot JW

Hi ,

This is a very intersting discussion thats going on. Now i tried doing
absolutely the same thing in FireFox and it just did not work. There are
2 things that i tried

1) <script language="javascript" type="text/javascript">

       function sendToClipboard(s){

     window.clipboardData.setData('text', "123456789");
       }

When i do this, i get the follwoing error in the JavaScript Console of
Firefox -:

Error: window.clipboardData has no properties
Source File: file:///C:/Ankur/Test/CopyTest.html
Line: 15

2) And when i try to do something like this -:

<script language="javascript" type="text/javascript">

    function sendToClipboard(s){

    if( window.clipboardData && clipboardData.setData ){
     alert("In the IF loop with s being " + s);
     window.clipboardData.setData("Text", s);
     }else{

       alert("In the ELSE loop ");
         }

    }
</script>

In this case , it does not even go to the IF loop. It just goes to the
else and comes out.

Any advise will be really appreciated. Thanks in advance

That's the whole idea of the condition; FireFox does not support
window.clipboardData, so you cannot populate data to the clipboard using JS
with this browser...

Hi JW,

Thanks a bunch for your reply and clearing that doubt.

Now if you are saying that window.clipboardData cannot be used with
Firefox, then can you please advise as to how may i achieve the same
functionality in Firefox, ie copying some data on the browser so that i
can paste it later somewhere using Ctrl V .

Thanks Again
Ankur

I don't think it is possible in FireFox without a special extension like the
one found at: http://www.gratisdei.com/copytoclip.xpi
