作者：feiwen 时间：2024-04-19 10:06:36
本文实例讲述了JS使用ajax从xml文件动态获取数据显示的方法。分享给大家供大家参考。具体分析如下：
下面的JS代码通过ajax检索xml文件的内容动态展示到网页，真个页面无刷新
<!DOCTYPE html>
<html>
<head>
<script>
function loadXMLDoc(url)
{
var xmlhttp;
var txt,x,xx,i;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
txt="<table border='1'><tr><th>Title</th><th>Artist</th></tr>";
x=xmlhttp.responseXML.documentElement.getElementsByTagName("CD");
for (i=0;i<x.length;i++)
{
txt=txt + "<tr>";
xx=x[i].getElementsByTagName("TITLE");
{
try
{
txt=txt + "<td>" + xx[0].firstChild.nodeValue + "</td>";
}
catch (er)
{
txt=txt + "<td> </td>";
}
}
xx=x[i].getElementsByTagName("ARTIST");
{
try
{
txt=txt + "<td>" + xx[0].firstChild.nodeValue + "</td>";
}
catch (er)
{
txt=txt + "<td> </td>";
}
}
txt=txt + "</tr>";
}
txt=txt + "</table>";
document.getElementById('txtCDInfo').innerHTML=txt;
}
}
xmlhttp.open("GET",url,true);
xmlhttp.send();
}
</script>
</head>
<body>
<div id="txtCDInfo">
<button onclick="loadXMLDoc('cd_catalog.xml')">Get CD info</button>
</div>
</body>
