function copyToClipboard(txt) {
          if (window.clipboardData) {
              window.clipboardData.clearData();
              clipboardData.setData("Text", txt);
              alert("复制成功！");

          } else if (navigator.userAgent.indexOf("Opera") != -1) {
              window.location = txt;
          } else if (window.netscape) {
              try {
                  netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
              } catch (e) {
                  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'");
              }
              var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
              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("复制成功！");
          }
      }
