Seven, browser compatible CopyToClipboard ("Copy content")

function CopyToClipboard (TXT) {if (window.clipboarddata) {window.clipboardData.clearData ();
        Clipboarddata.setdata ("Text", txt); Alert ("Copy succeeded!")
 
      ");
      else if (navigator.userAgent.indexOf ("Opera")!=-1) {window.location = txt; else if (Window.netscape) {try {netscape.security.PrivilegeManager.enablePrivilege ("Universalxpconne
        CT "); catch (E) {alert ("Rejected by browser!")
        \ nplease type ' About:config ' in the browser address bar and enter \ n then set ' Signed.applets.codebase_principal_support ' to ' true '); var clip = components.classes[' @mozilla. Org/widget/clipboard;1 '].createinstance (Components.interfaces.nsIClipboa
        RD);
        if (!clip) return; var trans = components.classes[' @mozilla. Org/widget/transferable;1 '].createinstance (
        Components.interfaces.nsITransferable);
        if (!trans) return;
        Trans.adddataflavor ("Text/unicode");
        var str = new Object ();
     var len = new Object ();   var str = components.classes["@mozilla. Org/supports-string;1"].createinstance (
        Components.interfaces.nsISupportsString);
        var copytext = txt;
        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); Alert ("Copy succeeded!")
      "); }
    }

Eight, compatible with the major browser replication code (combined with Zeroclipboard.js)
