兼容IE和火狐、crome的返回XML文件内容
1、XML文件
num.xml
<?xml version="1.0" encoding="utf-8" ?>
<shows>
<show>
<name>blue</name>
<email>bule@126.com</email>
</show>
<show>
<name>yellow</name>
<email>yellow@126.com</email>
</show>
<show>
<name>green</name>
<email>green@126.com</email>
</show>
</shows>
2、ajax.js
function getHttpObject()
{
var xhr = null;
if(window.XMLHttpRequest)
{
xhr = new XMLHttpRequest();
}else if(window.ActiveXObject)
{
xhr= new ActiveXObject("Msxml2.XMLHTTP");
}
return xhr;
}
function ajax(url,fnSucc,fnFail)
{
var oAjax = getHttpObject();
oAjax.open('GET',url,true);
oAjax.send();
oAjax.onreadystatechange = function()
{
if(oAjax.readyState == 4)
{
if(oAjax.status ==200)
{
//var contacts = JSON.parse(oAjax.responseText);
fnSucc(oAjax.responseXML);
}else
{
if(fnFail) fnFail(oAjax.status);
}
}
}
}
3、html文件
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta content="text/html; charset=utf-8;" http-equiv="Content-Type">
<title>讀取XML內容</title>
<script type="text/javascript" src="ajax_XML.js"></script>
<script type="text/javascript">
window.onload = function()
{
ajax('num.xml',function(str){
console.log(str);
/* var xmlRoot = str.documentElement;
var channel = xmlRoot.childNodes.item(0);
var itemlist = channel.childNodes;*/
//alert(str.firstChild[0].firstChild[0].firstChild[0].nodeValue);
var node = str.getElementsByTagName('show');
for(var i=0;i<node.length;i++)
{
if(window.XMLHttpRequest)
{
//ff crome 下利用textContent返回 <name>blue</name>z中的值.:node[i].getElementsByTagName('name')[0].textContent
alert(i+'name: '+node[i].getElementsByTagName('name')[0].textContent+' '+i+'email: '
+node[i].getElementsByTagName('email')[0].textContent);
}else if(window.ActiveXObject)
{
//ie下用text返回 <name>blue</name>z中的值.:node[i].childNodes[0].text
alert(i+'name: '+node[i].childNodes[0].text+' '+i+'email: '+node[i].childNodes[1].text);
}
}
});
}
</script>
</head>
