[PHP]XMLHTTP无刷新技术
如何做一个XMLHTTP无刷新页？我找了一段代码但是只有一半，还有＂test.php＂这个没有！有没有人帮我补一下？
<?
function loadXMLTreeDoc()
{
var url = "/test.php";
// branch for native XMLHttpRequest object
if (window.XMLHttpRequest)
{
req = new XMLHttpRequest();
req.onreadystatechange = processReqChange;
req.open("GET", url, true);
//req.setRequestHeader("text","text");
req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=utf-8');
req.send(null);
// branch for IE/Windows ActiveX version
}
else if (window.ActiveXObject)
{
isIE = true;
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req)
{
req.onreadystatechange = processReqChange;
req.open("GET", url, true);
//req.setRequestHeader("text","text");
req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=utf-8');
req.send();
}
}
//refresh on time
setTimeout( "loadXMLTreeDoc()" , 500 );
}
// handle onreadystatechange event of req object
function processReqChange() {
// only if req shows "loaded"
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.all.t.innerHTML=req.responseText;
req=null;
} else {
alert("Sorry,there was a problem retrieving the XML data, please check network!");
}
}
}
