Add to browser favorites/bookmarks from JavaScript but for all browsers (mine doesn't work in Chrome)?

Can anyone help, I am using the following for adding a bookmark to IE and Firefox but its not working in Chrome and I don't get my error msg saying "not supported" either..

Anybody know of a good script to support ALL browsers or at least to come back and tell me its not supported, I have access to jQuery - maybe there is some way to detect the browser

I am currently using this and it works for IE and Firefox but not chrome

if (window.sidebar) { // Mozilla Firefox
    window.sidebar.addPanel(name, url, "");
}
else if (window.external) { // IE
    window.external.AddFavorite(url, name);
}
else if (window.opera && window.print) {
    window.external.AddFavorite(url, name);
}
else {
    alert('not supported');
}

Sorry, but there's no cross-browser way to do this. Your FF example is broken as well: It won't create a regular bookmark, but a bookmark set to be opened in the sidebar. You'd have to use the bookmark-service to create an actual bookmark, but this'll fail due to security restrictions.

After discovering - like Edison! - a bunch of ways this doesn't work, I eventually came across this page that says adding bookmarks via JS is explicitly disabled in Chrome. Unfortunately it does not explain why.

Update: I was asked to expand this answer by another SO user...

My links and buttons for this function all have a class="addbookmark" associated with them. When the user agent is Chrome, I use some jQuery to disable the links and explain why:

<script type="text/javascript" src="/scripts/jquery-1.4.2.min.js"></script> 
<script type="text/javascript" src="/scripts/bookmark.js"></script> 
<script> 
    title='A Label for this Bookmark, ie title of this page'; // for example, not really generated this way... 

    $jQuery(document).ready(function(){ 
        // chrome does not permit addToFavorites() function by design 
        if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1) { 
            $('.addbookmark').attr({ 
                title: 'This function is not available in Google Chrome. Click the star symbol at the end of the address-bar or hit Ctrl-D to create a bookmark.', 
                href: 'javascript:return false' 
            }) 
            .css({opacity: .25});       // dim the button/link 
        } 
    }); 
</script>

And then elsewhere on the page:

 <td rowspan="2" class="noprint" style="width:24px;"> 
     <a class="addbookmark" title="Save a Bookmark for this page" 
        href="javascript:addToFavorites(location.href,title)"> 
        <img style="width:24px; height:24px; padding-top:2px;" src="/images/bookmark.gif"></a> 
 </td>

... which is by no means perfect, but it seems one's options are fairly limited.

The version of jQuery isn't important, and it's up to you whether you want a local copy or hot-link to the google version. bookmark.js is pretty much exactly as per the OP's code:

$ cat /scripts/bookmark.js 
/* simple cross-browser script for adding a bookmark 
    source: http://stackoverflow.com/questions/992844/add-to-browser-favourites-bookmarks-from-javascript-but-for-all-browsers-mine-do 
*/ 
function addToFavorites(url, name) { 
    if (window.sidebar) { // Mozilla Firefox 
        window.sidebar.addPanel(name, url, ""); 
    } else if (window.external) { // IE 
        window.external.AddFavorite(url, name); 
    } else if (window.opera && window.print) { 
        window.external.AddFavorite(url, name); 
    } else { 
        alert("Sorry! Your browser doesn't appear to support this function."); 
    } 
}

Hope that's useful.

You can always alert the client to press ctr+D. This is universal across all browsers. It's tacky, but just as useful to the client.

I couldnt get the above example to work. Anyway the answer to the original question 'its not working in CHROME and i don't get my error msg saying "not supported" either..' is due to the line

else if (window.external) { // IE

chrome actually passes this test and then obiously fails to add a bookmark. I changed this line to

else if(window.external && !window.chrome)  // IE

and now you get the 'not supported' message. I actually removed this message and called the function hotKeys() to get a more meaningful alert. I had to make a few changes to get that to work

function showHotKeys() 
{ 
var ua = navigator.userAgent.toLowerCase(); 
var str = ''; 
var isWebkit = (ua.indexOf('webkit') != - 1); 
var isMac = (ua.indexOf('mac') != - 1); 

if (ua.indexOf('konqueror') != - 1) { 
    str = 'CTRL + B'; // Konqueror 
} else if (window.home || isWebkit || isMac) { 
    str = (isMac ? 'Command/Cmd' : 'CTRL') + ' + D'; // Netscape, Safari, iCab
} 
return ((str) ? 'Press ' + str + ' to bookmark this page.' : str); 
}

My approach with help of jQuery.
Tested in IE 6-8, Fx 1-25, Opera 7-14. Degrades gracefully in Chrome, Saf.

CSS:

.no-js .link-bookmark {
   display: none;
}

JS:

/* ... Bookmark current page ... */
var $favLink = $('.link-bookmark');

if ( window.sidebar || 'AddFavorite' in window.external || window.opera ) {
    $favLink.show();
}

// add a 'rel' attrib if Op 7+ && Fx >= 23
if ( window.opera || window.sidebar ) {
    var $favLinkAttrRel = $favLink.attr('rel');
    if ( typeof $favLinkAttrRel !== "undefined" && $favLinkAttrRel !== false ) { // don't overwrite the rel attr if already set
        $favLink.attr('rel', 'sidebar');
    }
}

$favLink.click(function( event ) {
//event.preventDefault(); // prevent the anchor tag from sending the user off to the link
var url = this.href;
var $title = $('title').text();

// IE Favorite
if ( 'AddFavorite' in window.external ) {
    event.preventDefault();
    window.external.AddFavorite(url, $title);
}
// Fx <23 Bookmark, 'addPanel' not available from v23 on any more.
else if ( 'addPanel' in window.sidebar ) {
    event.preventDefault();
    window.sidebar.addPanel($title, url, '');
}
// Op 7+ && Fx >= 23
else if ( window.opera || window.sidebar ) {
    $favLink.attr('title', $title);
    return true; // do nothing - the rel="sidebar" should do the trick
}
// for Saf, Konq etc - browsers who do not support bookmarking scripts
else {
    event.preventDefault();
    alert('Your browser doesn\'t support the bookmark functionality,'
    + 'please add this page to your bookmarks manually.');
} 
});
