flash 和asp 分页的一点心得

//显示程序如下:
//桢名称 "list"
stop();
var logList = new XML();
var logroot;
var page:Number; //当前页
var Tpage:Number; //保存总页
var Tnum:Number; //总日志数
var logname:String; //日志分类名称
var temp;
var i:Number;

//这里我用一个数组储存了对应的id号,如果用组件就不用这么麻烦了
var ids = new Array(15);

//两个按钮,用来翻页
bn_u.enabled = false;
bn_d.enabled = false;
if (page == null or page<1) {
page = 1;
}
//------------------------------
//清除函数;
function myclear() {
for (i=1; i<16; i++) {
ids[i-1] = 0;
list["lbn"+i]._visible = false;
list["ltitle"+i].text = "";
list["lauthor"+i] = "";
list["ltime"+i] = "";
}
}
//--------------------------------------
//--------------------------------------
myclear();
pageInfo.text = "正在读取数据...";
logList.ignoreWhite = true;
logList.load("Tree_list.asp?log_cat="+cat_id+"&page="+page);
//------------------------------------------------
//get数据函数
function logFunc(e) {
if (e) {
logroot = logList.firstChild;
logname = logroot.attributes.logname;
Tpage = logroot.attributes.Tpage;
Tnum = logroot.attributes.Tnum;
temp = logroot.firstChild;
list.ltitle1.text = Ftitle(temp.firstChild.nodeValue, 22);
list.lauthor1 = temp.attributes.author;
list.ltime1 = temp.attributes.Addtime;
ids[0] = temp.attributes.id;
i = 1;
list.lbn1._visible = true;
//循环读取节点
while (temp.nextSibling != null) {
temp = temp.nextSibling;
i++;
//如果是用别的方式显示,只需要改一下就可以了
ids[i-1] = temp.attributes.id;
list["lbn"+i]._visible = true;
list["ltitle"+i].text = Ftitle(temp.firstChild.nodeValue, 22);
list["lauthor"+i] = temp.attributes.author;
list["ltime"+i] = temp.attributes.Addtime;
}
pageInfo.text = logname+"共有日志"+Tnum+"篇 共"+Tpage+"页 当前是第"+page+"页 "+"15/页";
bn_u.enabled = true;
bn_d.enabled = true;
} else {
pageInfo.text = "当前没有日志。";
list.ltitle1.text = "读取数据出错，请联系管理员！";
}
}

//一个自定义的格式标题的函数,怕标题太长
function Ftitle(s, n) {
if (length(s)>n) {
s = s.substring(0, n-1)+"...";
}
return s;
}
logList.onLoad = logFunc;
//-------------------------------------
//按钮动作
Bn_up = new Object();
//按钮事件,判断页面大小是否超过值
Bn_up.click = function(evt) {
if (page>1) {
_root.page--;
gotoAndPlay("cycle");
} else {
stop();
}
};
Bn_d = new Object();
Bn_d.click = function(evt) {
if (page<Tpage) {
_root.page++;
gotoAndPlay("cycle");
} else {
stop();
}
};
bn_u.addEventListener("click", Bn_up);
bn_d.addEventListener("click", Bn_d);

桢"cycle"只有一个话:
gotoAndPlay("list");
//形成一个简单的循环

Tree_list.asp:
//log 是我的日志表 ,log_cat是分类表
下面的asp很清楚了
