Dephi中擷取webbrowser選取地區的html程式碼範例

這個問題來自論壇提問，範例程式碼如下，主要是要瞭解Document對象

//------這個論壇居然不支援delphi代碼樣式

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    Memo1: TMemo;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  WebBrowser1.Navigate('www.csdn.net');
end;

procedure TForm1.Button1Click(Sender: TObject);
var doc:mshtml.IHTMLDocument2;
var select:mshtml.IHTMLTxtRange;
begin
   doc:= self.WebBrowser1.Document as mshtml.IHTMLDocument2;
   select:=doc.selection.createRange() as mshtml.IHTMLTxtRange;
   memo1.Text:=  select.htmlText;
end;

end.
