Down2.0 源代码
 程序代码/******
本程序需要IE5.5+支持,Flash Player 8.0+支持.
编译需要Notepad.exe以及Flash Pro 8
******/
文件包括:
- readme.txt(说明文件)
- main.flv(Flash主要文件)
- main.html(浏览的脚本代码)
Flash Action Script部分重要代码
程序代码

Java Script部分重要代码
程序代码
//建立表格.自动排列,加亮,添加事件触发.
function cre(){
var lis = 4;
var al = a.length;
var alv = al%lis;
var an = (al-alv)/lis;
var na=0;
var sn = 20;
//
var oT=document.createElement("table");
oT.style.width="100%";
for(var n1 = 0; n1<an; n1++){
var or = document.createElement("tr");
for (var n2 = 0; n2<lis;n2++){
var od = document.createElement("td");
var oa = document.createElement("a");
var s1 = a[na].url.slice(a[na].url.lastIndexOf("/")+1,a[na].url.lastIndexOf("."));
if(s1.length > sn){
s2 = s1.slice(0,sn)+"..";
}else{
s2 = s1;
}
oa.appendChild(document.createTextNode(s2));
oa.title = s1;
oa.style.fontSize="14";
switch (a[na].lv) {
case "0":
oa.style.color="#696969";
break;
case "1":
oa.style.color="#ff9999";
break;
case "2":
oa.style.color="#ff6699";
break;
case "3":
oa.style.color="#ff3399";
break;
case "4":
oa.style.color="#ff0099";
break;
}
oa.style.cursor="hand";
od.style.width="25%";
od.appendChild(oa);
od.onClick="ca(\""+na+"\")";
or.appendChild(od);
na++;
}
oT.appendChild(or);
}
var odiv=document.getElementById("div");
odiv.innerHTML=oT.outerHTML;
}
自此,Down2.0算是完工了,虽然数据库和表现页面连在一起让人很不满意,但也算过得去.
Down3.0的制作也结束了.
这个是Down2.0 源代码的原代码，请知道的高手解释一下原理
