Ajax+ASP和Flash+ASP数据存取方法
两种数据存取方法差不多。
===============================
下面是一个ChatRoom的Ajax部分代码:
var ajaxHttpRequest = false;
function ajaxInit() {
if(window.XMLHttpRequest) { //Mozilla, Opera, ...
ajaxHttpRequest = new XMLHttpRequest();
if(ajaxHttpRequest.overrideMimeType) {
ajaxHttpRequest.overrideMimeType("text/xml");
}
}
else if(window.ActiveXObject) { //IE
try{
ajaxHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e) {
try{
ajaxHttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e) {
}
}
}
if(!ajaxHttpRequest) {
window.alert("不能创建XMLHttpRequest对象实例");
return false;
}
}

function ajaxSendPost(url, values, processRequest) {
ajaxHttpRequest.open("POST",url,true);
ajaxHttpRequest.setRequestHeader("Content-Type","application/x-/s?wd=flash+ajax
