找到 FileBrowser/FileWorkerBase.cs 文件
Response.Write( @"(function(){var d=document.domain;while (true){try{var A=window.top.opener.document.domain;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,‘‘);if (d.length==0) break;try{document.domain=d;}catch (e){break;}}})();" );
Response.Write( @"(function(){var d=document.domain;while (true){try{var A=window.top.opener.document.domain;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,‘‘);if (d.length==0) break;try{document.domain=d;}catch (e){break;}}})();" );
修改成：
Response.Write(@"(function(){var d=document.domain;while (true){try{var A=window.top.opener.document.domain;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,‘‘);if (d.length==0) break;}})();");
Response.Write(@"(function(){var d=document.domain;while (true){try{var A=window.top.opener.document.domain;break;}catch(e) {};d=d.replace(/.*?(?:\.|$)/,‘‘);if (d.length==0) break;}})();");
