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.btn1Click(Sender: TObject);
var
  s: string;
begin
  s := RunJs(mmo1.Text, 'myFunction()'); //留意这里，第二个参数是Js函数、要带乱号，直接写函数名称只会返回全部Js代码;
  ShowMessage(s);
end;
