注意：此方法在Firefox下无法使用!一、XMLHTTP的基本使用方法
GET方式
<script>
var HttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
HttpRequest.open("GET", "http://www.google.com", false);
HttpRequest.send();
alert(HttpRequest.responseText);
</script>
POST方式
<script>
var HttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
HttpRequest.open("POST", "http://www.google.com", false);
HttpRequest.send("user=wo");
alert(HttpRequest.responseText);
</script> 稍微复杂些的代码
<script>
var HttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
HttpRequest.open("POST", "http://www.google.com", false);
HttpRequest.setRequestHeader("Content-Type", "text/xml;charset=utf-8");
HttpRequest.setRequestHeader("HOST", "www.google.com");
HttpRequest.setRequestHeader("user-agent", "Mozilla/4.0");
HttpRequest.send("user=wo");
switch(HttpRequest.Status)
{
case 200:
alert(HttpRequest.responseText);
break;
default:
alert("状态:" + HttpRequest.Status);
}
</script> 二、客户端自动刷新
<script>
function RefreshMe()
{
var HttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
// 2秒钟取得一次数据
timer = window.setInterval("RefreshMe()", 2000);
}
</script>
<body onload="RefreshMe()">
