最近项目中用到了FLASH多文件上传功能,根据虽然CS4是最新的,但还是选择了CS3
FLASH CS3,使用的是ActionScript 3.0,在开发的过程中发现 AS3与AS2的区别是非常大的,比如geturl等,下面是完整源代码,希望对大家有用:
上传进度控件cs文件
package
{
import flash.display.*;
import flash.text.*;
public class UCProgress extends MovieClip
{
public function UCProgress()
{
_txt.autoSize = TextFieldAutoSize.LEFT;
_txt.text = '已完成:0%';
_mc.width = 0;
}
public function ready(n):void
{
_txt.text = '就绪:' + n;
// _txt.textColor = 0x666666;
}
public function updateinfo(n,b,t,fn):void
{
_txt.text = fn
_txt1.text = n + '%';
// _txt.textColor = 0xff6600;
_mc.width = b/t * 165;
}
public function complete(n):void
{
_txt.text = '上传完成:' + n;
// _txt.textColor = 0x0066cc;
}

}
