See this string Code:
<SCRIPT type = text/JavaScript>
<! -- // --> <! [CDATA [//> <! --
VaR spacestaticdata = {
Style: '/style/common /',
Hostid: 2241772,
Hostpath :'',
Hostname: 'mycm22 ',
Visitorname: 'mycm22 ',
Hostnickname: 'mycm22 ',
Visitornickname: 'mycm22 ',
Visitorpopoaccount :'',
Visitorpopopasswdmd5 :'',
Visitorrank: '123 ',
Pagename: 'prevresource'
};
// --> <!]>
</SCRIPT>
Little has not studied XML knowledge.
"<! -- // --> <! [CDATA [//> <! --
// --> <!]> "
This part of the code is completely incomprehensible. Please advise me. Copy codeThe Code is as follows: CDATA is something in XML. The purpose of this Code is to pass the XHTML verification, because in XML, the content in CDATA is "text" and does not need to be escaped, there can be <> & and other symbols that are not allowed in XML.
