在 Delphi 中调用 JavaScript(2)

代码文件:

---

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    Edit1: TEdit;
    Label1: TLabel;
    procedure Button1Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses ComObj;

{此函数需要 ComObj 单元的支持}
{参数 JsCode 是要执行的 Js 代码; 参数 JsVar 是要返回的变量}
function RunJs(const JsCode, JsVar: string): string;
var
  script: OleVariant;
begin
  try
    script := CreateOleObject('ScriptControl');
    script.Language := 'JavaScript';
    script.ExecuteStatement(JsCode);
    Result := script.Eval(JsVar);
  except
    Result := '';
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  s: string;
begin
  s := RunJs(Memo1.Text, 'str');
  ShowMessage(s);
end;

end.
