我作了个测试文件看看:
1:makeRequest.html
<html>
<body>
<script type="text/javascript" language="javascript">
var http_request = false;
function makeRequest(url) {
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Giving up
Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = alertContents;
http_request.open('GET', url, true);
http_request.send(null);
}
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
var xmldoc = http_request.responseXML;
var root_node = xmldoc.getElementsByTagName('root').item(0);
alert(root_node.firstChild.data);
} else {
alert('数据请求失败.');
}
}
}
</script>
<span
style="cursor: pointer; text-decoration: underline"
>
发送请求
</span>
</body>
</html>
2.test.xml
<?xml version="1.0" ?>
<root>I'm a test.</root>
为什么不能够取得test.xml中的文本内容那?
