2.复制专题地址和 url 地址，传给 QQ/MSN 上的好友

 1  function copyToClipboard(txt) { 2             if (window.clipboardData) { 3                 window.clipboardData.clearData(); 4                 clipboardData.setData("Text", txt); 5                 alert("复制成功！"); 6  7             } else if (navigator.userAgent.indexOf("Opera") != -1) { 8                 window.location = txt; 9             } else if (window.netscape) {10                 try {11                     netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");12                 } catch (e) {13                     alert("被浏览器拒绝！\n请在浏览器地址栏输入'about:config'并回车\n然后将 'signed.applets.codebase_principal_support'设置为'true'");14                 }15                 var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);16                 if (!clip)17                     return;18                 var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);19                 if (!trans)20                     return;21                 trans.addDataFlavor("text/unicode");22                 var str = new Object();23                 var len = new Object();24                 var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);25                 var copytext = txt;26                 str.data = copytext;27                 trans.setTransferData("text/unicode", str, copytext.length * 2);28                 var clipid = Components.interfaces.nsIClipboard;29                 if (!clip)30                     return false;31                 clip.setData(trans, null, clipid.kGlobalClipboard);32                 alert("复制成功！");33             }34         }
