=================================
下面是我一个Flash留言的数据读取的部分代码: http://www.linjimu.com.cn/Flash
ls = new LoadVars();
ls.Action = "Read";
ls.CurrentPage = _root.CurrentPage;
//ls load and send ,ld load result;
ld = new LoadVars();
ls.sendAndLoad("Advice.asp", ld, "post");
_root.gotoAndPlay("Wait");
_root.WaitBtText = "返回留言";
_root.Frame = "Send";
_root.TextMessage.text = "\n 正在读取留言数据...\n\n 请稍后...";
ld.onLoad = function(ok) {
if (ok) {
if (this.message == "OK") {
_root.gotoAndPlay("ListView");
} else {
_root.gotoAndPlay("Wait");
_root.WaitBtText = "返回留言";
_root.Frame = "Send";
_root.TextMessage.text = " 读取数据不成功!\n\n 可能发生以下错误:\n 1.
读取数据超时,请稍后再试.\n 2.空间不支持ASP."+this.message;
}
} else {
_root.gotoAndPlay("Wait");
_root.WaitBtText = "返回留言";
_root.Frame = "Send";
_root.TextMessage.text = " 读取数据不成功!\n\n 可能发生以下错误:\n 1.读取数据
超时,请稍后再试.\n 2.空间不支持ASP.";
}
};
delete ls;
stop();

相比一下,他们都有相似之处:
AJax:
ajaxHttpRequest.open("POST",url,true);//发送数据的方法,类型,url地址..
ajaxHttpRequest.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
ajaxHttpRequest.send(values);//发送数据
ajaxHttpRequest.onreadystatechange = processRequest; //processRequest是一个过程函数,对返回数据的
处理。
--------
Flash:
ls = new LoadVars();
ls.Action = "Read";//是发送数据
ls.CurrentPage = _root.CurrentPage;//是发送数据
//ls load and send ,ld load result;
ld = new LoadVars();
ls.sendAndLoad("Advice.asp", ld, "post");//发送数据的方法,类型,url地址..
ld.onLoad = function(ok) {//code...} //也是一个过程函数,对返回数据的处理。
不过,在web方面,Ajax的页面完全基于HTML,文本网页会更有利于搜索引擎的搜索。
Flash开发人员还是偏重图形、动画设计,Flash能够更容易的调用浏览器以外的外部资源。比如摄像头、麦克风等。然而这是普通的HTML无法完成的。
他们的关系请去baidu一下:flash与AJAX http://www.baidu.com/s?wd=flash+ajax
