JS代码



<head>

<script type="text/javascript">

//生成XMLDOC对象

var xmlDoc=null;

}

//CODE FOR FF，Mozilla,Opera  --  在非IE下使用 document.implementation.createDocument生成XMLDOC对象

else if(document.implementation.createDocument)

{

    xmldoc=document.implementation.createDocument("","",null);   //非IE下要使用DOM创建XMLDOM对象的  

}

else

{

    alert("Your brower cannot handle this script");

}



//

xmlDoc.async=false;

x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue

你的getElemntsByTagName拼写错误

getElementsByTagName
