1.加载后，以表格形式输出数据：<html>
<body>
<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","/example/xdom/books.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("book");
document.write("<tr><th>category</th><th>title</th><th>author</th></tr>");
for (i=0;i<x.length;i++)
{
document.write("<tr><td>");
document.write(x[i].getAttribute("category"));
document.write("</td><td>");
document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
document.write("</td><td>");
document.write(x[i].getElementsByTagName("author")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");
</script>
</body>
</html>
2.导航查看数据：<html>
<head>
<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","/example/xmle/cd_catalog.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
x=xmlDoc.getElementsByTagName("CD");
i=0;
function displayCD()
{
art= x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue ;
tit = x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue ;
year= x[i].getElementsByTagName("YEAR")[0].childNodes[0].nodeValue ;
txt="ARTIST:"+art+"<br/>TITLE:"+tit+"<br/>YEAR:"+year;
document.getElementById("show").innerHTML=txt;
}
function next()
{
if(i<x.length-1)
{
i++;
displayCD();
}
}
function previous()
{
if(i>0)
{
i--;
displayCD();
}
}
</script>
</head>
<body onload="displayCD()">
<div id='show'></div></br>
<input type="button" onclick="previous()" value="<<"/>
<input type="button" onclick="next()" value=">>"/>
</body>
</html>
3.当点击专辑信息时，出现专辑详情：
<html>
<head>
<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","/example/xmle/cd_catalog.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
x=xmlDoc.getElementsByTagName("CD");
function displayCDInfo(i)
{
artist=(x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue);
title=(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue);
year=(x[i].getElementsByTagName("YEAR")[0].childNodes[0].nodeValue);
country=(x[i].getElementsByTagName("COUNTRY")[0].childNodes[0].nodeValue);
company=(x[i].getElementsByTagName("COMPANY")[0].childNodes[0].nodeValue);
price=(x[i].getElementsByTagName("PRICE")[0].childNodes[0].nodeValue);
txt="Artist: "+artist+"<br />Title: "+title+"<br />Year: "+year+"<br />Country: "+country+"<br />Company: "+company+"<br />Price: "+price ;
document.getElementById("showCD").innerHTML=txt;
}
</script>
</head>
<body>
<div id='showCD'>点击某个 CD 就可显示专辑信息：</div><br />
<script type="text/javascript">
document.write("<table border='1'><tr><th>artist</th><th>title</th></tr>");
for(var i=0;i<x.length;i++){
document.write("<tr onclick='displayCDInfo("+i+")'><td>");
document.write(x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue+"</td><td>");
document.write(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue+"</td></tr>");
}
document.write("</table>");
</script>
</body>
</html>
