如何在没有TWebBrowser的Delphi程序中执行Javascript？

优点：

>自Windows 98以来,它可用于所有默认的Windows安装.
这是死的容易.
>不需要第三方Delphi组件.
>不需要dll的包装器,所以部署很简单.

缺点：

>你会产生新的流程.在网络服务器上启动cscript.exe感觉错误.我不知道安全性是什么.
>您无法直接访问脚本引擎的内部.

示例程序(这只是一个概念证明…可能有更好的方法来做到这一点)：

program JsExample;    
{$APPTYPE CONSOLE}

uses Windows,IoUtils;

// start a new process
function RunProgram(const aProg,aParams: string; aHow2Show: Word; const aWaitTime: dword): boolean;
var LProcInfo: TProcessInformation; LStartUpInfo: TStartupInfo;
begin
  FillChar(LStartUpInfo,SizeOf(TStartupInfo),#0); FillChar(LProcInfo,SizeOf(TProcessInformation),#0);
  with LStartUpInfo do
  begin
    cb := SizeOf(LStartUpInfo);
    lpReserved := nil; lpDesktop := nil; lpTitle := nil; lpReserved2 := nil; cbReserved2 := 0;
    dwFlags := STARTF_USESHOWWINDOW;
    wShowWindow := aHow2Show;
  end;
  Result := CreateProcess(nil,PChar(aProg + ' ' + aParams),nil,false,CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS,LStartUpInfo,LProcInfo);
  if Result then
    Result := WaitForSingleObject(LProcInfo.hProcess,aWaitTime) <> WAIT_FAILED;
end;

// run javascript code
procedure RunJs(const aJavaScript: String);
var LTmpFileName: String;
begin
  LTmpFileName := TPath.ChangeExtension(TPath.GetTempFileName,'.js');
  try
    TFile.WriteAllText(LTmpFileName,aJavaScript);
    RunProgram('cscript','/NOLOGO "' + LTmpFileName + '"',SW_SHOWNORMAL,INFINITE);
  finally
    TFile.Delete(LTmpFileName);
  end;
end;



// main
begin

  // execute some stupid javascript sample code
  RunJs
  (
    'var Text="Hello from JavaScript!";' + // creating a js variable
    'for(var i=0;i<Text.length;i++)' +     // creating a js looop
    '  WScript.Echo(Text.charAt(i));'      // calling string.charAt() and print some stuff
  );

  ReadLn;    
end.

这个方法真的很简单..将JavaScript写入一个文件,然后调用cscript.exe作为参数.
