Clipboard copy function working

2008/10/17 13:28 in HTML, Javascript

When copying trackback address or shortcut url on the articles, clipboard function is really useful.
But there are some compatibility issue in browsers.

I checked below function is working on Microsoft Internet Explorer. For supporting Firefox, you need to find another solution.

function copy_clip(meintext){
    if (window.clipboardData) { 
        // the IE-manier
        window.clipboardData.setData("Text", meintext);
        // waarschijnlijk niet de beste manier om Moz/NS te detecteren;
        // het is mij echter onbekend vanaf welke versie dit precies werkt:
    } else if (window.netscape) {
        // dit is belangrijk maar staat nergens duidelijk vermeld:
        // you have to sign the code to enable this, or see notes below
        netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

        // maak een interface naar het clipboard
        var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
        if (!clip) return;

        // maak een transferable
        var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
        if (!trans) return;

        // specificeer wat voor soort data we op willen halen; text in dit geval
        trans.addDataFlavor('text/unicode');

        // om de data uit de transferable te halen hebben we 2 nieuwe objecten nodig om het in op te slaan
        var str = new Object();
        var len = new Object();

        var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);

        var copytext=meintext;

        str.data=copytext;

        trans.setTransferData("text/unicode",str,copytext.length*2);

        var clipid=Components.interfaces.nsIClipboard;

        if (!clip) return false;

        clip.setData(trans,null,clipid.kGlobalClipboard);
    }

    var msg = alert_msg['url_copy'];
    if(typeof(msg)=='undefined'||!msg) return;
    alert(msg);
}



Usage sample

<a href=# onclick='copy_clip( "http://kurapa.com"); return false;'>http://kurapa.com</a>
