<script type="text/javascript" language="javascript">
var http_request = false;
function makeRequest(url) {
if (window.XMLHttpRequest) { //mozilla...浏览器
http_request = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE 浏览器
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
http_request.onreadystatechange = alertContents; //事件
http_request.open('GET', url, true); //以GET方式发送请求
http_request.send(null);
}
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) { //请求正确收到
//在请求正确收到后用消息框显示内容
alert(http_request.responseText);
} else { //请求有错
alert('There was a problem with the request.');
}
}
}
</script>
<a href="#" onclick="makeRequest('test.html')">Make a request</a>
