TWebBrowser 与 MSHTML(2): 获取 window 对象的时机

这是在页面下载完毕后即刻获取:

---

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    Button2: TButton;
    procedure FormCreate(Sender: TObject);
    procedure WebBrowser1DocumentComplete(ASender: TObject;
      const pDisp: IDispatch; var URL: OleVariant);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

uses MSHTML;
var window: IHTMLWindow2;

{建立时同时打开页面}
procedure TForm1.FormCreate(Sender: TObject);
begin
  WebBrowser1.Align := alTop;
  WebBrowser1.Navigate('http://del.cnblogs.com');
end;

{当页面打开完毕时获取 window 对象}
procedure TForm1.WebBrowser1DocumentComplete(ASender: TObject;
  const pDisp: IDispatch; var URL: OleVariant);
begin
  if pDisp = (ASender as TWebBrowser).Application then
  begin
    window := ((ASender as TWebBrowser).Document as IHTMLDocument2).parentWindow;
  end;
end;

end.
