测试 “http://pan.baidu.com/s/1kTIBpMR” 顶楼提供数据 5分钟以内完成 可能机器配置的关系

1. @if (0)==(0) echo off
   
2. for /f "delims=" %%i in ('dir /a-d/b *.txt') do cscript //nologo //E:JScript "%~f0" <"%%i">#&move# "%%i" >nul
   
3. pause&exit
   
4. @end;
   
5. String.prototype.strreg = function() {
   
6.    return this.replace
   
7.       (/(.+?;)(\d+|\d+(\.\d+));(\d+|\d+(\.\d+));(\d+|\d+(\.\d+));(\d+|\d+(\.\d+));(\d+|\d+(\.\d+));(\d+|\d+(\.\d+))$/gm,
   
8.        function(a,b,c,d,e,f,g,h,j,k,l,m,n) {
   
9.            return b + (Math.floor(c*100)/100).toFixed(3) + ";" + (Math.floor(e*100)/100).toFixed(3) + ";" + (Math.floor(g*100)/100).toFixed(3) + ";" + (Math.floor(j*100)/100).toFixed(3) + ";" + (Math.floor(l*100)/100).toFixed(2) + ";" + (Math.floor(n*100)/100).toFixed(2);
   
10.    });
    
11. };
    
12. WScript.echo(WScript.StdIn.ReadAll().strreg())
