我尝试使用w3验证器验证我的html代码。 其中一个结果是：
Warning No Character Encoding Found! Falling back to UTF-8.
None of the standards sources gave any information on the character encoding labeling for this document. Without encoding information it is impossible to reliably validate the document. As a fallback solution, the "UTF-8" encoding was used to read the content and attempt to perform the validation, but this is likely to fail for all non-trivial documents.
第二个错误是：
Warning Unable to Determine Parse Mode!
the MIME Media Type (text/html) can be used for XML or SGML document types
No known Document Type could be detected
No XML declaration (e.g <?xml version="1.0"?>) could be found at the beginning of the document.
No XML namespace (e.g <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">) could be found at the root of the document.
第三个错误：
Warning No DOCTYPE found! Checking with default HTML 4.01 Transitional Document Type.
No DOCTYPE Declaration could be found or recognized in this document. This generally means that the document is not declaring its Document Type at the top. It can also mean that the DOCTYPE declaration contains a spelling error, or that it is not using the correct syntax.
但是，当我点击它在开头显示的网站上的浏览页面来源时：
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="profile" href="http://gmpg.org/xfn/11" />
<link rel="pingback" href="http://ijmra.is-best.net/xmlrpc.php" />
<title>my website</title>
等.... 我该如何纠正这些错误？ ... 更新：w3验证器用于此验证的源输入：
<html><body><script type="text/javascript" src="/aes.js" ></script><script>function toNumbers(d){var e=[];d.replace(/(..)/g,function(d){e.push(parseInt(d,16))});return e}function toHex(){for(var d=[],d=1==arguments.length&&arguments[0].constructor==Array?arguments[0]:arguments,e="",f=0;f<d.length;f++)e+=(16>d[f]?"0":"")+d[f].toString(16);return e.toLowerCase()}var a=toNumbers("f655ba9d09a112d4968c63579db590b4"),b=toNumbers("98344c2eee86c3994890592585b49f80"),c=toNumbers("7efc82a5df893398691d5e53fda9f0d9");document.cookie="__test="+toHex(slowAES.decrypt(c,2,a,b))+"; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/";location.href="http://my-site.net/?ckattempt=1";</script><noscript>This site requires Javascript to work, please enable Javascript in your browser or use a browser with Javascript support</noscript></body></html>
